The Commission is required to prepare an annual report to the Mayor and Council each year. This report is the Commission's sixteenth Annual Report. It includes topics on customer service, water quality, water supply, water resource planning, conservation, and capital improvements. This report covers information and activities for fiscal year (FI) ending June 30, 2011 and calendar year (CY) 2011. The Executive Summary contains a briefing on several of the Utility's significant operations during this past year as well as projects specific to water issues facing the Town of Oro Valley (Town) in the future. More detailed information may be found in specific sections of this report and the appendices. CUSTOMER SERVICE The Town of Oro Valley Water Utility (Water Utility or Utility) has 18,545 customer connections serving a population of 49,104. This includes both the customers within the Town boundaries and the Countryside area. During CY 2011, 71 new meter connections were installed and approximately 2.4 billion gallons (7,350 acre feet) of potable water was delivered to our customers. In addition, approximately 735 million gallons (2,256 acre feet) of reclaimed water was delivered for golf course irrigation and other uses. WATER QUALITY For the tenth consecutive year, the Utility is proud to report that it did not experience any water quality violations for Total Coliform bacteria. The number of tests performed in CY 2011 was 2,969 and our water quality was in compliance with all standards established by federal and state agencies. In addition to testing for water quality, the Water Utility administers a backflow prevention program to protect our water system from potential contamination. Oro Valley wells have excellent water quality. Our Staff s diligent operation and monitoring of the water system is critical to providing a safe and reliable water supply for our customers. CURRENT WATER SUPPLY Oro Valley currently delivers water from three sources of supply. Groundwater is pumped from wells in the aquifer below the Town and delivered through the potable water distribution system. Central Arizona Project (CAP) water deliveries began January 24, 2012 to Oro Valley's potable water system through Tucson Water's Distribution System (wheeling) in accordance with an intergovernmental agreement with the City of Tucson - Tucson Water. Reclaimed water is used for irrigation and is delivered through a separate reclaimed water distribution system. Oro Valley also uses its CAP water indirectly through groundwater storage credits. -4- Groundwater levels continue to decline in the Oro Valley aquifer but to a lesser extent than in previous years because of the decrease in groundwater pumping. Operation of the reclaimed water system has slowed the groundwater decline, thus conserving, preserving and protecting our aquifer and our groundwater supply. The use of reclaimed water is a significant accomplishment, but it is not the only renewable source of supply available to assure a sustained reliable water supply. The Utility recently began delivery of 1,500 acre feet per year of its CAP water allocation through a connection with the Tucson Water system. This will further reduce our reliance on and use of groundwater. Plans for future use of our remaining CAP water allocation are being developed cooperatively with Marana, Metro Water, Flowing Wells, and Tucson Water. In CY 2011 approximately 7,734 acre feet of groundwater was pumped from the aquifer. Well water levels rose an average of 1.06 feet in the Oro Valley Water Service Area and declined 2.21 feet in the Countryside Water Service Area in CY 2011. The Utility continues to use its CAP water through an agreement with Kai Farms and through permits to store in Central Arizona Water Conservation District recharge projects. This allows the Utility to obtain long-term groundwater storage credits within the Tucson Active Management Area. Participation in the Lower Santa Cruz River Managed In -Channel Recharge Project also provides the Utility with long term storage credits from unused wastewater effluent. The use of our existing groundwater allowance account and long-term storage credits reduces our monetary payments to the Central Arizona Groundwater Replenishment District for groundwater replenishment requirements. RECLAIMED WATER SYSTEM The Town of Oro Valley delivers reclaimed water for irrigation to five existing golf courses and to Painted Sky Elementary School athletic fields. In 2011 these five golf courses and Painted Sky Elementary School used approximately 735 million gallons or 2,256 acre feet of reclaimed water for irrigation purposes. This resulted in a reduction of approximately 23.5% in the amount of groundwater pumped from the aquifer. WATER CONSERVATION The Water Conservation Program continues to be a vital asset in assisting the Utility to achieve its overall water management goals. During the past year, the primary focus of the conservation program continued to be residential water use audits. In 2011, 119 audits were performed. Since the program's inception in 2003, participating customers received 1,484 free water audits, which saved our customers both water and money. The Utility encourages water conservation by educating our customers. Water use audits, which save our customers money and reduce the demands on our system, are a key component of the Water Conservation Program. Stage 1-Drought Conditions were in place for 2011 and continue to remain in place. This condition calls for voluntary restrictions under the Town's Drought Preparedness Plan. Oro Valley Water Utility also participated regionally with other water providers through membership in the Water Conservation Alliance of Southern Arizona. -5- WATER RATES AND IMPACT FEES The functions and duties of the Water Utility Commission and Staff include reviewing and developing recommendations for water revenue requirements, water rates and fee structures. In 2011, recommendations regarding water rates, fees and charges were provided in the Water Rates Analysis Report. There was no recommended increase in water rates and fees in 2011. CONCLUSION The Oro Valley Water Utility Commission is proud to serve the Mayor and Council of the Town of Oro Valley and its residents and customers. We are pleased to present this Annual Report to the Mayor and Council for their consideration. While much has been accomplished in the past year, the Water Utility Commission and Staff look forward to direction regarding those items detailed in the Report. We thank the Mayor and Council for their consideration, direction and guidance. Any questions regarding this report should be directed to Philip Saletta, Director, Oro Valley Water Utility at 229-5010. Additional information for the Oro Valley Water Utility can also be found on the Town website at www.orovalleyaz.gov/Town Government/WaterUtility INTRODUCTION The Oro Valley Water Utility is a municipally owned water utility that has been in operation since May 1, 1996. During this time, the Utility has achieved a number of significant goals. The Utility installed 71 new water connections in CY 2011, a 0.38% growth rate, for a total of 18,545 water connections. We continue to operate under the Intergovernmental Agreement with Tucson Water regarding the delivery of reclaimed water to the Thornydale Pump Station. In addition, starting in January of 2012, renewable Central Arizona Project (CAP) water is being delivered under an Intergovernmental Agreement (IGA) with the City of Tucson. The Utility's infrastructure has grown to meet existing and growing demands with the addition of 2.17 miles of potable water mains. The Utility continues to be fiscally sound. Water development impact fees, which fund expansion of the water delivery system, have been collected to ensure that growth pays its fair share. There was no water rate increase recommended for 2012. However, the rate increase approved in 2010 was implemented in October 2011. This was an increase in the Groundwater Preservation Fee that pays for renewable water supplies. The Utility has also decreased its debt over the last several years. The following are some of the Utility's resources and assets as of December 31, 2011: Resources: Employees: 36 Groundwater Supply (Assured Water Supply): 13,384 acre feet per year Reclaimed Water: 2,300 acre feet per year Effluent Water: L500 acre feet per year CAP Water: 10,3 05 acre feet per year Long Term Storage Credits: 13,075 acre feet Groundwater Allowance Account: 13,189 acre feet Assets: Water Service Areas: Oro Valley Water Service Area and Countryside Water Service Area Water Distribution Storage Reservoirs: 19 Potable Water Reservoir Capacity: 11,600,000 gallons Reclaimed Water Reservoir Capacity: 1,500,000 gallons Water Mains: 354 miles Potable Water Booster Stations: 25 Reclaimed Water Booster Stations: 2 Operating Wells: 22 � Well Pumping Capacity: 12,448 gallons per minute (gpm) The Utility continues to plan for future water supply both for existing customers and new growth. This is demonstrated by the cooperative regional planning for the delivery of CAP water. -7- CUSTOMER SERVICE Customer Service personnel include Customer Service Representatives (CSRs) and Utility Operators. This staff is responsible for meter reading, meter installation, billing and collection and customer service for 18,545 water service connections serving 49,104 people. The Utility has grown over the past year and in 2011 an additional 71 meters were installed for a growth rate of 0.3 8%. Over 4,742 customer accounts were changed in 2011, primarily due to opening and closing of accounts for new move -ins and winter residents. The Utility delivered 2.4 billion gallons (7,350 acre feet) of potable water to our customers in 2011 and over 735 million gallons (2,256 acre feet) of reclaimed water for irrigation to five golf courses and a school playground. Combined, this totals 3.13 billion gallons (9,606 acre feet) of water delivered and billed to our customers. The Customer Service Division mailed and processed 225,573 bills and 12,442 delinquent notices to our customers during calendar year 2011. The Customer Service Division responds to customer concerns that arise from the operation and management of the water system and in 2011 responded to 33,718 customer contacts averaging 135 contacts per day. Customer contacts can range from handling a payment to responding to questions or problems related to billing, opening or closing an account, water quality or pressure and flow problems. CSRs work closely with field personnel to respond in a timely manner to customer concerns. CSRs are generally the first and sometimes the only contact our customers may have with the Utility. Their training -and skills are utilized on a daily basis while addressing customer concerns. Ongoing training provided to CSRs include: stress management, dealing with difficult people, utility billing software and security. Staying abreast of new information is a key element to consistently improving customer service as well as providing for the mental and physical well being of Utility employees. Customer Service staff collects and posts payments for the Water Utility, Pima County Regional Wastewater Reclamation Department and the Town's Storm Water Utility. A fee is charged to Pima County and the Town for this service. The Customer Service Division bills the Town Storm Water Utility charges to residents within the Town that are Oro Valley Water customers, Tucson Water customers and Metro Water customers. The Water Utility also collects taxes on water use that are imposed by the State of Arizona and the Town of Oro Valley. These taxes are then distributed to the State and Town. The Water Utility receives all of its revenues from water rates and fees and does not receive any funding from taxes. The Utility continually updates customer account information on the Water -on -the -Web site. This includes current billing and payment information as well as a two year history of water usage. Customers have the ability to pay their water bill with credit cards and view their current water bill online. This option helps to facilitate payment of water bills. In addition, to enhance customer service and to assist in decreasing costs, the Utility offers an e-bill or paperless option. This feature sends customers electronic notification that their current water bill is ready to view on the Water -on -the -Web site. Utility customers may request- e-billing online. To date, 789 customers are enrolled in this program. -8- The Utility offers an automatic payment. program through an Automated Clearing House (ACH) in which the amount of the customer's water bill is automatically deducted from their checking or savings account. There are currently 4,678 customers enrolled in this program. For those customers who pay their water bills online through their bank, the Utility implemented electronic or "paperless" bank to bank transfer of payment funds. This allows their payments to reach us up to 1 week faster than the traditional paper checks. The Utility has a toll free telephone number that accepts customer credit card payments through an Interactive Voice Response System (IVR). In addition, customers can make payments online at the Water -on -the -Web site. The Utility received 8,791 credit card payments in 2011 utilizing these payment methods. An additional 1,294 customers paid with credit cards in the Utility office. Payments via credit cards represented 9% of the total Utility revenue received in CY 2011. The successful implementation of this service has provided alternative payment methods particularly for those customers with delinquent accounts and those customers who frequently travel. During the last quarter of 2011, the Utility upgraded the Countryside service area with new meters that provide real time data via Advanced Metering Infrastructure (AMI). This project is discussed in more detail in the Meters Division. As part of the AMI project, F1exNet software allows Customer Service staff to view customer consumption data and pinpoint high water use on their computers while communicating with the customer in person or on the telephone. Customer Service Staff can view water use from their desk F1exNet software has the capability to monitor leaks on a daily basis. In turn, this allows early leak notification to our customers that will ultimately save them money and conserve water wasted by leaks that are not discovered and repaired timely. This new technology monitors water use on an hourly basis, can trigger alerts and allows for better utilization of resources with the least amount of waste. Examples of daily and hourly data available through FlexNet software may be found in Appendix A. AMI allows the staff to read meters from our office and provides us the ability to obtain billing reads on the same day each month. -9- I F Over the past year, the Customer Service Division has received numerous complimentary comments, emails and letters regarding their personal and helpful customer assistance. This level of professional and courteous service is paramount to the successful operation of the Water Utility. Utility statistics including new meter installations, customer contacts, and water deliveries for CY 2011 may be found in Appendix A. LI I -10- METERS DIVISION All personnel in the Meters Division are licensed operators. During 2011 they conducted 219,973 meter readings and responded to 4,606 customer requests in the field. These included checking meter accuracy, meter replacement, water pressure and leaks. Staff works closely with the builders and contractors of Oro Valley to ensure that water meters are installed on a timely basis. During the past 3 years, the Meters Division has implemented several significant programs in their division. The table below illustrates these programs and the status of each. Program Start Date Status as of 12/31/11 Meter Replacement 2008 Replaced 3,629 water meters Meter Testing 2009 Tested 57 large meters Automated Meter Reading (AMR) 2009 Installed 474 meters with AMR equipment Advanced Metering 2011 Installed 2,244 with AMI equipment Infrastructure (AMI) The Meter Replacement Program provides for more accurate measurements of water usage and also assures that the volume of water billed is accurate. In addition, meter replacement is one of the Best Management Practices approved by the ADWR to meet water conservation requirements. The Meter Testing Program involves testing all water meters 3-inches and larger on an annual basis. It is important to be vigilant on larger meters to minimize the loss of revenue due to under reporting of significant flows through these larger meters. Automated Meter Reading (AMR) equipment consists of encoder registers that attach to water meters and transmit data via radio waves. As the meter route is driven, a computer located inside the vehicle receives the radio waves and stores the data until it is downloaded to the billing software. The focus for installation of this equipment has been in residential areas that are, labor intensive to read and commercial corridors because of the high flow of traffic which can be a safety issue. AMR equipment will eventually be replaced with Advanced Metering Infrastructure (AMI). With AMI, the meters will be read from the office rather than when driving a meter route. All AMR equipment can be easily replaced with AMI equipment. Once replaced, the equipment manufacturer has agreed to give the Utility a credit for the AMR equipment. AMI equipment consists . of fixed antennas, base stations, modems, computer servers, encoder registers, and electronic meters. All of this equipment has a 20-year life. The encoder (also known as an MXU) reads the electronic meter and via the. antenna, base stations and modem, transmits the data to computer servers located at the Town Hall. Data received from the Sensus equipment is managed by their proprietary software known as FlexNet. FlexNet allows the Utility to read the meters from our office. There are numerous features of FlexNet that will be valuable to not only the Utility but to our customers as well. -11- FlexNet can provide alarms for different situations including leak detection, low battery, tampering, and non-functioning meters. Using FlexNet, Utility Staff can review water use history on an hourly, daily, weekly or monthly basis. This is extremely valuable in assisting our customers with leak detection and ultimately will eliminate leak disputes. The electronic meter referenced above is known as iPERL. The iPERL is a state of the art meter providing an innovative concept in water metering. The iPERL meter innovates measurement technology with unparalleled low flow accuracy and high flow durability. With no moving parts, the iPERL meter requires minimal maintenance resulting in lower life -cycle costs. The iPERL meters register water flow as low as 1 / 10 of a gallon per minute thus measuring water that had previously passed through the system undetected. AMI Project The Utility began deployment of AMI equipment in October of 2011 in the Countryside service area with the installation of the antenna, base station and computer servers. The meter replacement portion of this project began on November 1 st and consisted of replacing approximately 2,000 meters ranging in size from 5/8-inch to 2-inch. The meter replacement portion was successfully completed on December 24th. With the implementation of AMI in the Countryside service area, the Meters Division staff no longer has to manually read these meters. They are being read electronically from our office. This capability allows staff that used to read the Countryside routes to assist in reading the remaining routes in this billing cycle thus reducing the overall read time by I V2 days. Utility staff will now have more time to focus on routine maintenance including service line repairs, meter testing, and meter replacements. The integration of AMI throughout the entire water service area will change the operating culture of the Meters Division. This technology will promote proactive maintenance with the capability to routinely monitor the meters for leaks and malfunctions which will in turn allow us to notify customers within 24 hours if they have a leak. The FlexNet software will facilitate significant improvements in our customer service capabilities with access to water use history on an hourly, daily, weekly or monthly basis. As part of the AMI project, the Utility will be implementing a customer web portal. The customer web portal will be linked to the Utility's website. Each customer will have a personal identification number that will allow them access to their water use history. Just as with FlexNet, our customers will be able to view their individual water usage on an hourly, daily, weekly or monthly basis. This information will provide an opportunity for them to become more aware of their water use, help establish or adjust irrigation settings, pinpoint when water use is occurring to assist in leak detection, and hopefully, help them conserve water. -12- WERL water meter Dual port meter and AMU installation AMI installation -13- WATER QUALITY There is a complex and extensive framework of regulatory requirements and sampling methodology in place to ensure clean, safe drinking water is served by every public water system in Arizona. Protection of drinking water quality starts with an assessment of the drinking water source quality and continues through regulations that govern water system design and construction. Finally, drinking water quality is assured through scheduled tests required of all public water systems for a wide variety of potential contaminants. As a result of these regulations and continued testing, drinking water supplies in Oro Valley and in many areas throughout the United States are among the cleanest and safest in the world. �k Yi r 4 r d M I k, p.v xm xm. x �"Wy u , '} �+ ". � rFaP y�>K: .��, '.ti _ •� .o-.'i .. r' ���f p„vl"4 �.vi"`kM T+"4' ��i'x f ��� � .. .� � - • 1 .r �..� �i'�- "M � »�R�� �. -� 5 a� ..- : .i'�V°^S" ..r ..., i'..� _ w11 a.9 . - ♦Y �•'� • ... .� .. � W � ., ~ �"dn "� � ... a .. ��ej:� Water Quality Testing The Water Utility operates two potable water systems. The Oro Valley Water Service Area (OVWSA) that has a Public Water System Number of AZ0410164. It also operates a potable system that is not located within the Town boundaries, known as the Countryside Water Service Area (CSWSA) that has a Public Water System Number of AZ0410175. Over the course of a year the Utility collects hundreds of water samples from approximately 19 "point of entry" sites. These sites include groundwater wells, reservoirs and pumping stations. The Utility also samples from 58 sampling stations located in neighborhoods throughout the water distribution system specifically selected to represent the water quality that is delivered to our customers. Water samples are taken from 50 private residences within the Oro Valley area and tested for lead and copper. The Utility provides all water quality testing results to the Arizona Department of Environmental Quality (ADEQ) and works closely with that agency to ensure all Federal and State standards are met. The website for ADEQ is www.azdeq. _ ov. The Utility's State certified water operators are legally responsible for the health and safety of our customers. The operators meet this responsibility by maintaining a daily vigilance over the system's production, distribution, and water quality. All of our water operators are licensed and attend continuing education and training through Personal Development Hours required by ADEQ. This also benefits our community and adds value to the water Utility. -14- Additionally, comprehensive emergency plans have been developed to ensure an immediate response to any adverse water situation. The Town's water system is in full compliance with all State and Federal regulations. In 2011 the Utility received 2,969 analytical results for required water sampling and operational data. Please refer to Appendix B for the Environmental Protection Agency's required contaminant monitoring list and the Utility's most recent analysis. Drinking water standards are regulations that the Environmental Protection Agency (EPA) sets to control the level of contaminants in the nation's drinking water. These standards are part of the Safe Drinking Water Act's "multiple barrier" approach to drinking water protection which includes, assessing and protecting drinking water sources; protecting wells and collection systems; making sure water is treated by qualified operators; ensuring the integrity of distribution systems; and making information available to the public on the quality of their drinking water. Community water suppliers throughout the country are required to provide an annual water quality report to their customers. The report provides information about the source of the drinking water, and any contaminants detected in the water. The OVWSA and the CSWSA Consumer Confidence Reports are annually distributed to all customers in June. The report is also available in the Utility's office and on the website. There are two categories of drinking water standards. A National Primary Drinking Water Regulation or (primary standard) is a legally enforceable standard that applies to public water systems. Primary standards protect drinking water quality by limiting the levels of specific contaminants that can adversely affect public health and are known or anticipated to occur in water. They take the form of Maximum Contaminant Levels (MCL) or Treatment Techniques. A National Secondary Drinking Water Regulation or (secondary) standard is a non -enforceable guideline regarding contaminants that may cause cosmetic effects (such as skin or tooth discoloration) or aesthetic effects (such as taste, odor, or color) in drinking water. The EPA recommends secondary standards to water systems but does not require systems to comply. However, ADEQ requires the Utility to sample these contaminants every three years. A contaminant list and the most recent analysis for the Utility are included in Appendix B. Detection of a contaminant in drinking water does not necessarily represent a threat to public health. Current technology allows water utilities to detect extremely. low levels of contaminants in drinking water. All drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants. Oro Valley's groundwater contains naturally occurring dissolved minerals and organic compounds, which have been leached from the rock, sediments, and plant materials through which the water traveled. One would expect to find constituents (ions), such as -calcium, magnesium, chloride, bicarbonate, sulfate, and metals such as iron, copper, arsenic and lead, which may be either beneficial or harmless at low concentrations. However, these constituents are harmful at high concentrations. � Other contaminants that may be present in source water are microbial contaminants, such as viruses and bacteria. The Utility disinfects its water source by adding sodium hypochlorite at 1 a level of 0.2 to 0.8 parts per million (ppm), as a precaution against bacterial growth. J -15- The Total Coliform bacteria group is used as an indicator to more closely monitor the distribution system for possible unwanted bacteria. During 2011, the Utility collected 737 f samples or analysis of Total Coliform bacteria, of which two resulted positive for bacteria. p y Repeat samples were found to be negative. This is a direct result of a successful disinfection program, effective system monitoring, proficient sampling methods, and routine maintenance. Two inorganic compounds found in groundwater are presently of special interest. These compounds are arsenic and fluoride. Arizona is among a handful of western states whose soil contains naturally high levels of arsenic, which can increase risks for some types of cancer. As of January 2006, all water systems were required to comply with the EPA's MCL for arsenic of no more than 10 parts per billion (ppb) as compared to the previous standard of 50 ppb. EPA estimates that approximately one-third of the systems nationwide subject to the new standard presently exceed the 10 ppb arsenic standard. In 2011, the Utility conducted compliance tests for arsenic in its wells. All "points of entry" to the drinking water system were reported less than 5 ppb. These results are significantly below the new arsenic MCL. Fluoride at a level of 1.0 ppm has been shown to help prevent tooth decay. In high concentrations however, fluoride can be harmful. Oro Valley's groundwater has fluoride at low concentrations ranging from <0.5 (the laboratory's detection level) to 0.53 ppm. The Utility regularly receives inquiries concerning water hardness. Water hardness is a m and magnesium. During CY 2011 the hardness L measurement of the concentration of calcium b g levels in Oro Valley range from 1.8 to 7.0 grains per gallon. These levels are considered low and as such water softeners would not be required. Water quality standards are continually researched and regularly modified and changed based on scientific research. In early 2006, EPA released the STAGE 2 Disinfectants .and Disinfection By -Products Rule. This is an important component to the agency's multi - pronged strategy to reduce drinking water risks to human health through improved standards for pathogens as well as disinfection by-products. Compliance with the new Groundwater Rule began on December 1 of 2009, and is expected to require many small groundwater systems to add disinfection to their systems. The Utility's disinfection program was implemented for both systems in 2002 and presently meets the Ground water Rule requirement. EPA's rule revisions to Lead and Copper was published in 2006. The revisions are a targeted update of the current rule including guidance on lead in drinking water in schools, including information on improved testing, monitoring and maintenance efforts. Nitrate, lead, perchlorate, fluoride, and chromium VI are all getting renewed attention from the USEPA as more information has become available and their potential health effects have become better understood. Proposed and Pending USEPA Regulations; • Revised Total Coliform Rule November 2012 • Third Unregulated Contaminant Monitoring Rule March 2012 • Revised Long -Term Lead and Copper Rule 2014 • Carcinogenic Volatile Organic Chemicals Rule 2015 • Epichlorohydrin and Acrylamide TBD -16- Oro Valley is a growing community in an arid environment. The future of drinking water quality will continue to command serious attention by everyone involved with water supply for the community. Water quality compliance requirements will continue to increase in both complexity and cost, requiring the support and resources needed to ensure regulatory compliance and to provide a safe and reliable water supply to our customers. BACKFLOW PREVENTION Backflow prevention is an important component of water quality. The Town of Oro Valley Water Utility implemented the Backflow Prevention Program in response to requirements set forth in the Arizona State Drinking Water Regulations. The Backflow Prevention Section administers these requirements in accordance with the Town of Oro Valley Ordinance No. (0) 07-21, the Arizona Department of Environmental Quality Administrative Code, section R18-4-B 115, the International Plumbing Code and the guidelines of the University of Southern California Foundation for Cross Connection Control and Hydraulic Research. The Backflow Prevention Program is designed to protect the public water system from high risk service connections which include, but are not limited to, commercial, fire and irrigation. By state statute single family residences are exempt unless a known hazard exists on the premises. The Backflow Prevention Section oversees 1,240 backflow prevention assemblies. The Utility is required to notify each customer on an annual basis to have each active assembly tested. An initial notification letter is mailed followed by a second and final letter. Customers are notified by phone when the second letter is sent. The backflow prevention assemblies must also be tested if they are replaced, relocated or repaired. Completed test forms are recorded into a database and the hard copies must be kept by the Water Utility for 3 years. All assemblies are surveyed on a 3 year cycle. The backflow assemblies that are owned by the Town and in service are maintained, tested and inspected by the Water Utility Backflow Prevention Section. The following are some of the major activities and accomplishments that were performed by the Backflow Prevention Section in 2011: ➢ 151 backflow assemblies owned by the Town of Oro Valley were tested ➢ 43 repairs on in ground and construction water backflow prevention assemblies ➢ 64 permits for new and replacement backflow prevention assemblies The program works to keep the water supply safe from contaminants that could be introduced into the distribution system through backflow, backsiphonage or backpressure from our customers plumbing systems or internal processes. -17- CURRENT WATER SUPPLY Developed Water Resources • Groundwater: 13,384 acre feet per year • CAP Water: 1,500 acre feet per year • Reclaimed water: 2,300 acre feet per year The Town of Oro Valley has a groundwater supply of 13,384 acre feet per year based on its Designation of Assured Water Supply (DAWS) from ADWR. Under our DAWS for each calendar year our groundwater pumping cannot exceed this amount. This amount is an upper limit of pumping and even though we pump less than this amount, we are required to replace or replenish the total amount pumped. In addition, our sustainable groundwater production is modeled to be 5,500 acre feet per year which we are currently exceeding and this has caused significant groundwater level declines over the years. Developing our renewable water supplies reduces our replacement requirements and decreases our ground water level declines protecting and preserving our aquifer. In 2011, Oro- Valley pumped 7,734 acre feet of groundwater. A requirement of our DAWS is that the Town must be a member of the Central Arizona Groundwater Replenishment District (CAGRD). The Town has a Member Service Area Agreement with CAGRD that was approved by Resolution (R) 97-06. Each year under this agreement, the CAGRD assesses the Town an increasing portion of the annual groundwater pumped at an increasing rate to replenish what is deemed "excess groundwater withdrawal". Use of our recovery wells has helped to reduce a portion of the CAGRD obligations and costs which are increasing in price per acre foot. The Water Utility operates in two water service areas: the Oro Valley Water Service Area (OVWSA) and the Countryside Water Service Area (CSWSA). The table below provides water capacities of the wells in their respective water service areas. The maximum daily usage occurred on August 31, 2011 for the OVWSA and on June 27, 2011 for the CSWSA. Water Service Area Well Capacity Daily Capacity Average Day Max Day Oro Valley (OVWSA) 1052 GPM 15.34 MGD 5.92 MGD 8.54 MGD Countryside (CSWSA) 1,796 GPM 2.59 MGD 0.65 MGD 0.97 MGD Groundwater studies indicate that the Oro Valley aquifer has a sustainable groundwater production rate of approximately 5,500 acre feet per year. -In 2011, well production was 7,734 acre feet of groundwater from our aquifer. This resulted in pumping our aquifer 2,234 acre feet more than the sustainable groundwater production rate. To monitor the impact on the Oro Valley aquifer, each year the Utility measures the groundwater levels in all of its wells. For wells in the OVWSA, the average annual well water level decline for the last 5 years is 2.60 feet and for calendar year 2011 and there was an average well water level rise of 1.06 feet. For wells in the CSWSA, the average annual well water level decline for the last 5 years is 0.85 feet and for calendar year 2011 there was an average well water decline of 2.21 feet. For all wells, water level changes in CY 2011 ranged from a decline of 9.2 feet to a rise of 10.6 feet. Detailed information on the individual wells and their associated water levels may be found in Appendix C. -18- The Water Utility Staff will continue to monitor our well water levels and production capacity and plan for future well replacements and improvements to minimize well production capacity losses. Reducing groundwater production to a sustainable amount provides the only assurance of protecting and preserving our aquifer and reducing water level declines. The use of reclaimed water since October of 2005 has helped to reduce the impact on the Oro Valley aquifer over the last six years. The Town of Oro Valley currently has a reclaimed water supply of approximately 2,300 acre feet per year. This was acquired in 2003 under an Intergovernmental Agreement (IGA) with Tucson Water (TW). The IGA contains a complex formula for computing the annual allotment of effluent produced from the wastewater discharged to the sanitary sewer by Oro Valley Water Utility customers. The Town's effluent is treated at Pima County Wastewater facilities and then delivered to the TW Sweetwater Reclamation Facility where it is further treated for use in the reclaimed water system or recharged through the TW Sweetwater Recharge Facility. From there Oro Valley's reclaimed water is delivered through TW's reclaimed water conveyance system to Tangerine and Thornydale where it is pumped into Oro Valley's reclaimed water pipeline and distribution system. Undeveloped Water Resources • Central Arizona Project Water: 8,805 acre feet per year • Long -Term Storage Credits: 13,075 acre feet • Ground Water Allowance Account: 13,189 acre feet • Effluent Water: 1,500 acre feet per year The Town currently has undeveloped water resources that consist of our CAP water allocation, Long -Term Groundwater Storage Credits, Groundwater Allowance Account and effluent water. Until recently there was no infrastructure to deliver our undeveloped CAP water directly. On January 24, 2012, deliveries of our CAP water through a connection to the Tucson Water system began. In 2012, approximately 1,500 acre feet of our CAP water will be delivered (wheeled) to the Oro Valley Water Utility service area through a connection to the Tucson Water system. This project provides a "wet" renewable water supply to our community reducing groundwater use and reducing obligations to the CAGRD. The long- term groundwater storage credits are used indirectly through recovery wells as "paper water" credits that offset groundwater usage and reduce CAGRD obligations. The Town currently has a total allocation of CAP water in the amount of 10,305 acre feet per year under a Municipal and Industrial (M&I) subcontract with Central Arizona Water Conservation District (CAWCD). Of this amount, 1,500 acre feet are developed through the first phase of the IGA with Tucson. The remaining 8,805 acre feet of our CAP M&I subcontract water is critical to the Town and its future water supply. At this point there is no infrastructure in place to deliver this remaining amount of our CAP water. The Water Utility will continue to cooperate regionally with Metropolitan Domestic Water Improvement District, Flowing Wells Irrigation District, the Town of Marana and Tucson Water to develop our remaining CAP water. The development of our remaining CAP water will be paced based upon our water demands, aquifer conditions and new growth. -19- In addition to delivery of our CAP water through the TW system, the Town uses its CAP water for recharge pursuant to agreements with Kai Farms and the CAWCD. The Utility has obtained permits to store CAP water at Kai Farms, the Lower Santa Cruz Replenishment Project and the Pima Mine Road Recharge Project. The Utility stored 2,500 acre feet of CAP water in 2011 under the Kai Farms Agreement. The Water Utility also stored an additional 2,500 acre feet in CAWCD Lower Santa Cruz Recharge Facilities in 2011. Long-term storage credits have accumulated to 13,075 acre feet. The Utility will continue to use long-term storage credits to reduce a portion of the costs that are assessed annually by the CAGRD. The Utility will continue to recharge CAP water until such time the water is needed for future delivery. Although our membership in the CAGRD does meet the requirements for our DAWS, it does not provide "wet" water to the Town of Oro Valley. This is because the Water Utility and the CAGRD do not artificially recharge in the vicinity of the Oro Valley aquifer because there are no recharge facilities near or in Oro Valley. The recharge facilities utilized are located in the Tucson Active Management Area and near the CAP canal. In addition to our long-term storage credits, our Groundwater Allowance Account (GWA) must be used wisely and carefully managed over the next several years. This account had been depleted over past years from 75,000 acre feet to less than 10,000 acre feet. Recent purchases and subsequent pledges of Groundwater Extinguishment Credits (GECs) have increased the current balance of the GWA. The GWA balance as of the end of 2011 is 13,189 acre feet. Additional purchases of GECs will be evaluated and considered in the future to increase the balance of the Groundwater Allowance Account. By purchasing GECs, the Water Utility is saving its customers money by reducing monetary payments and obligations to the CAGRD and effectively managing our water resources. Included in the Town's DAWS is 4,000 acre feet per year of effluent which is the source of supply for our reclaimed water. Oro Valley owns its wastewater effluent through an IGA with the City of Tucson. The Utility delivered 2,256 acre feet of reclaimed water in 2011. The reclaimed water system supplies irrigation for five golf courses and the athletic fields at one elementary school. The remaining amount of undeveloped wastewater effluent is used for obligations to Pima County and for the Southern Arizona Water Rights Settlement Act (SAWRSA) obligations. Oro Valley delivers treated effluent as reclaimed water under another IGA with the City of Tucson. Under this IGA, Tucson Water will treat and deliver up to 3.75 MGD of reclaimed water daily to Oro Valley Water Utility. On days when additional reclaimed water was available, the Utility received up to 4.4 MGD which is the maximum pumping rate for the pumps at Thornydale Reservoir and Pump Station. In 2010, Tucson City Council and the Oro Valley Town Council approved an Intergovernmental Agreement which provided for a two-year time extension to determine the uninterruptible rate for the delivery of reclaimed water through the Tucson reclaimed water system and to negotiate changes to the IGA (TOV Resolution (R) 10-66). Under our Designation of Assured Water Supply, we are required to comply with the Third Management Plan in the Tucson Active Management Area. We have been in compliance with the Assured Water Supply Program and expect to meet all the requirements of this program in 2012. -20- WATER RESOURCE PLANNING AND MANAGEMENT The Utility's water resource planning effort incorporates previous studies and reports that have been developed over recent years. These reports provide the framework for water resource planning and management. Recently, the Water Utility developed plans for short- term and long-term options for the delivery of our CAP water. As of January 24, 2012, the Water Utility started delivering a portion of its CAP water through the Tucson Water System. The Water Utility, in cooperation with the other NW Water Providers and Tucson Water will continue planning for the development of our remaining CAP water allocation. Water resource planning will involve investigating alternatives for future water supply and delivery and will include the following: ➢ Groundwater development ➢ Reclaimed water system ➢ CAP water planning and development ➢ Water conservation Water resource planning will involve technical, financial, legal, political, institutional and environmental issues. Involving the public will be a key aspect of a successful program for future water supply. Funding for the development of CAP water and reclaimed water under the water resource planning effort has been included in the Utility's budget under the Alternative Water Resources Development Impact Fee Fund budget. The Water Utility has also been involved in an effort to acquire additional water supply from the Colorado River. This is a state wide effort known as the ADD Water Program (Acquire, Develop and Deliver), involving numerous water providers, the Central Arizona Project, the Arizona Department of Water Resources and the U.S. Bureau of Reclamation. The concept is to acquire additional water rights from the Colorado River and deliver that water through the use of excess capacity in the CAP canal and also expand the canal in the future. This is a long term project and effort that is in the early stages of determining the feasibility, economics, institutional and environmental issues related to acquiring, developing and delivering additional water supply from the Colorado River. Potable Water System The potable water system improvements are included in the Five -Year Capital Projects Program. The demand on our wells has been reduced due to use of reclaimed water for irrigation. In 2012 demand on our wells will be reduced further through the direct delivery of our CAP water. The use of reclaimed and CAP water preserves and protects our aquifer and valuable groundwater. All groundwater depletions must be replaced through the use of our recovery wells, our Groundwater Allowance Account, our Long -Term Storage Credits and/or the CAGRD. The Commission recommended and Council approved an IGA for the delivery of our CAP water through the Tucson Water system. This IGA was approved in July of 2011 and on January 24, 2012 delivery of approximately 1,500 acre feet per year of our CAP water commenced. The specifics of this CAP water delivery project are described in the Central Arizona Project Water section below. -21- Reclaimed Water The use of reclaimed water for turf irrigation has a beneficial impact on the Town's aquifer. The Utility will continue to look for opportunities to expand the customer base of the reclaimed water system for turf irrigation. Recently a new customer was added to the system. In addition, non -turf irrigation uses such as landscape irrigation, construction Water, dust control, car washes, street cleaning and recreational uses may also be served with reclaimed water to help reduce demands on the groundwater aquifer. The Development and Infrastructure Service Department is currently using reclaimed water for street cleaning and other approved maintenance purposes. This saves the Town both water and money. Central Arizona Project Water The Town through the Water Utility has been cooperating with Tucson Water and the Northwest Water Providers (Metropolitan Domestic Water Improvement District, Flowing Wells Irrigation District, and the Town of Marana) to develop CAP water delivery. Recently, the Town of Oro Valley and the City of Tucson executed an Intergovernmental Agreement to deliver a portion of Oro Valley's CAP water through the Tucson Water system. This project started deliveries of our CAP water on January 24, 2012. The IGA allows for up to 2,000 acre feet per year of Oro Valley's CAP water to be delivered (wheeled) through the Tucson Water (TW) system. The first phase is approximately 1,500 acre feet per year. This is a regionally cooperative project that protects and preserves the aquifer in the Oro Valley area and within the Tucson Active Management Area. This is a mutually beneficial project in that Tucson Water uses its excess capacity and receives revenues that shares in operations and maintenance costs. Oro Valley benefits in that it receives "wet" water deliveries of renewable CAP water and reduces its reliance on groundwater. -22- Oro Valley CAP Pump and Discharge Pipeline at Tucson Water's Naranja Reservoir Site Tucson Water's Central Avra Valley Storage and Recovery Project Oro Valley's CAP water is delivered from the CAP canal TW's recharge facilities at the Central Avra Valley Storage and Recovery Project and/or the Southern Avra Valley Storage and Recovery Project. The water is then pumped into the TW distribution system and delivered to the northern part of the TW system. A connection to the Oro Valley system was made near Naranj a and Shannon at the TW Naranj a C-Zone Reservoir site. A pump and pipeline was installed by Oro Valley to deliver its CAP water to the Oro Valley water distribution system. All water is accurately metered and accounted for to assure delivery volumes and for billing purposes. This cooperative project was made possible through the approval of the IGA by the Oro Valley Town Council and the Tucson City Council. Their approval and support of this project is evidence of the regional cooperation in Southern Arizona. The Oro Valley Water Utility Commission also supported and recommended approval of the IGA and this project to Town Council. Through teamwork and cooperation, Oro Valley Water " Utility staff and Tucson Water staff worked diligently to successfully accomplish this project on time and within budget. Oro Valley Water Utility will continue to plan for the development of the remaining portion of our CAP water. Long-term plans for recharge and recovery and/or treatment and direct delivery of our CAP water will be developed to determine the best alternative and plan for delivering our CAP water in the future. Cooperation as a member of the NW Water Providers to develop our CAP water and develop a regional project that provides for economies of scale will continue. In the short term, OVWU will also work with Tucson Water to increase deliveries of our CAP water in accordance with our IGA. This next fiscal year studies will be conducted to further develop options for increasing our CAP deliveries within the available amount of excess delivery and storage capacity of the Tucson Water system. -23- Central Arizona Project Canal The short-term development of our CAP water provides financial benefit to our customers in that it defers significant expense to develop a major capital project. In addition, it could also lower capital expenditures by reducing the amount of our remaining CAP water that would need to be developed. For example, the NW Water Providers originally looked at constructing a joint system, for up to 30,000 acre feet per year of CAP water into the northwest area to the four water providers. • r u 10 � Under this original scenario Oro Valley would participate in the project for p to ,0 0 0 acre feet per year or approximately one-third of the project. If Oro Valley develops 3,000 acre feet through the Tucson Water system on a permanent basis, this would reduce our portion of a project. larger 'ect. Since costs will be split among the participating water providers according to g p their system capacity and delivery location; Oro Valley's share of this project which was originally estimated to be $66 to $77 million dollars may be reduced to $55 to $60 million for a smaller project. This would still be a significant capital cost but would reduce and defer debt service which is a major element in our financial planning. The Town of Oro Valley is committed to the use of CAP water and will continue to work regionally to deliver our CAP water to our community. Recent economic conditions and slower growth rates may push projected water use demands further out in time. In addition, options to expand our CAP water deliveries through Tucson Water will also provide a benefit to defer major capital costs for the development and implementation of the more expensive options for CAP water delivery. CAP Water Treatment Pilot Study Project L The Town of Oro Valley and the other Northwest Water Providers developed a pilot study in cooperation with the Bureau of Reclamation and the University of Arizona to investigate water quality and salinity issues related to the treatment of CAP water. Tucson water also participated in the study. This pilot study was in operation for several years to investigate alternatives for the treatment of CAP water. It also included studying concentrate management options such as the use of halophyte (salt tolerant plants) irrigation as a means of disposing of the concentrate (salts) created by using reverse osmosis. -24- This project has been completed and the site is now decommissioned. The results of the study were reported to the NW Water Providers in a presentation prepared by the University of Arizona. The group is now considering additional water quality work related to recharge and recovery near the Lower Santa Cruz Recharge Project facilities. -25- WATER CONSERVATION PROGRAM Water conservation is an important factor in balancing our current and future water supply needs. Climate and the demands on our water supply place a significant impact on our water resources. Combine the state's arid climate with persistent drought conditions and the importance of managing our water resources effectively becomes even greater. The Utility recognizes the complexity and importance of sustained reliability. The Water Conservation Program is an important element in the overall water resource management efforts of the Utility. The water conservation program focuses on water audits, public outreach and education, incentives and cooperative relationships involving current issues and research. The following paragraphs provide insight into the various policies and programs that support water conservation for our customers and community. Water Audits Water audits for residential, commercial and homeowner association common areas continue to function as a key element in the water conservation program. Water Conservation Audit Audits are valuable educational tools that create an awareness -of water consumption by homeowners, businesses and the community as a whole. Utility staff completed 119 water audits during CY 2011. Figure 1 illustrates the total number of audits performed annually. Figure 2 illustrates the average number of audits conducted on a monthly basis from 2003 through 2011. The number of water audits conducted since the program began in 2003 totals 1A4. -26- 300 250 200 150 Q 100 50 0 Figure 1 Water Audits Completed 2003-2011 2003 2004 2005 2006 2007 2003 2009 2010 2011 Figure 2 Average Monthly Participation 2003-2011 25 V 20 a� � 15 O 0 10 .a Q 5 0 JAN FEB MAR APR MAY JUN JUL AUG SEP OCT NOV DEC MONTH Audits allow for a number of important conservation issues to be addressed while maintaining a cooperative relationship with our citizens and customers. As part of these free audits, customers are informed on general water conservation practices and principles. _27_ Irrigation systems and swimming pools, as well as interior household fixtures and appliances, are assessed for efficiency and proper use methods. Water use strategies are specifically tailored to the individual's water use habits and landscape needs. In addition, any observed leaks or equipment malfunctions are brought to the attention of the customer. Data collected during the audit is used to assess and recommend changes that may be needed to improve water use management. The Utility also uses the data collected in audits to identify the concerns of customers and help direct the focus of the conservation program. Analysis of these statistics allows the Utility to identify trends in town -wide water consumption and helps evaluate the effectiveness of the program. Water use by audit participants is tracked for the year prior to the audit and then compared to their use for a minimum of one full year after the audit. For audits completed in 2010, water consumption dropped approximately 22% in the first year after the audit resulting in an average water savings of over 4.9 million gallons. This is illustrated in Figure 3. Figure 3 Pre and Post Audit Water Use (1 Year Later) 259000,000 2020005000 0 m 15,000,000 ■ Pre Audit n ❑ Post Audit D 10,000,000 a� 5,000,000 0 2010 2009 2008 2007 2006 2005 2004 2003 Education and Resources Enhancing education, communication and water conservation related services for customers and the community is a very important aspect of the conservation program. The Utility is continually revising and assessing its services. The Utility provides a wide variety of adult and children's literature through various channels. The literature is free to our customers and is distributed through our main office, at the Oro Valley Library, at Town events, and during water audits. Landscape irrigation schedule cards are also available for watering guidelines related to plant types. In addition, the Water -Wise Landscaping for Southern Arizona CD is available in our main office. Conservation education and public outreach efforts during 2011 included participation in the following: speaking engagements for 3 professional organizations; presentations at 5 different Town sponsored events; publications in 12 issues of the Oro Valley Vista and 1 issue of The Talk of the Town. _28_ During 2011, the Water Utility partnered with the Conservation and Sustainability Division to install 3 rainwater harvesting cisterns in the Town Hall courtyard. Rainwater is collected from the rooftops of the buildings and captured by gutters to fill the cisterns. The cisterns have a series of underground piping that allows for distribution of the rainwater for landscape irrigation. There is a potential to collect 43,000 gallons of rainwater a year which is equivalent to the volume of water needed to fill three swimming pools. The FlexNet , software employed with the implementation of Advanced Metering Infrastructure has already proven to be a valuable resource in educating customers on their individual water use patterns. The ability to view hourly and daily water consumption history is extremely beneficial in teaching the customers how to detect leaks and how to adjust irrigation timers. In addition to literature and adult education classes, the Utility also offers toilet dye strips for leak detection purposes along with low flow shower heads, faucet aerators and in -line shut off valves to retrofit existing shower heads. Plans for a youth education program are discussed in the long-term goals section. Professional Memberships and Affiliations The water conservation staff continues to work with all divisions of the Utility and other departments within the Town. In addition, the Utility maintains memberships in professional organizations as a means of keeping up to date on current technology and providing progressive training for staff. The memberships include the American Water Works Association, the Irrigation Association and the Water Conservation Alliance of Southern Arizona (Water CASA). Renewable Water Resources Renewable water resources available to the Town include reclaimed water and CAP water. The Utility is currently serving reclaimed water to 5 golf courses, the athletic fields for 1 elementary school and 2 construction water hydrants. The Utility will continue to look for ways to expand the existing reclaimed water delivery system for other irrigation purposes. Additionally, the Utility has developed methods for the interim delivery of CAP water through Tucson Water's delivery system. CAP water deliveries began in January 2012. The Utility will also continue to study long-term options for the delivery of our CAP water. The use of renewable water resources is vital for groundwater conservation and preservation to help the Town achieve sustainability. Drought Preparedness Plan � The Utility has complied with a directive from ADWR by creating and filing.a Drought Preparedness Plan (DPP). The Town of Oro Valley maintained Stage 1 drought conditions throughout 2011. This condition calls for voluntary restrictions under the Town's DPP. The DPP identifies four different drought stages. Each stage identifies specific actions and restrictions that apply to all customers and Town facilities. Drought stages may change when two or more of the subsequent criteria or triggers are met. Criteria include temperature, precipitation, US Drought Monitor levels, and annual average decline of static groundwater levels in the aquifer underlying Oro Valley. -29- I Incentives The current incentive program includes irrigation system rain sensors which are sold at a reduced rate to our customers. To date, approximately 660 rain sensors have been sold to customers with active accounts. In an effort to better serve the customers, a Rain Sensor Installation Guide is distributed by the Utility and is also available on our website. Research Partnerships with Town departments, organizations and professionals in the water management industry continue to be vital in assessing the latest practical technologies and methodologies in water resource management. Information is then passed on to our customers through a variety of venues such as education programs, audits, and consultations. Policy In an effort to provide Oro Valley customers more options to expand their conservation efforts, changes were made to the Town Code in 2009 that requires the installation of graywater plumbing in new residential construction. In addition, the Landscape Section of the Town Code has been updated to reflect the importance of water conservation. Water plans will be required for irrigation water use on new multi -family, commercial and homeowner association common areas. New Code requirements will also apply to all projects that entail cumulative revegetation of 25% or more landscaped areas. Water plans or "budgets" allow properties -to monitor water use much more effectively and determine the presence of leaks much quicker. A fine or surcharge may be imposed when water budgets are exceeded. Water audits for new commercial development are a critical component of the revised code. These revisions became effective June 2010. Long Term Goals I1 Ll F1 The Utility continues to evaluate rebates and incentives as potential tools in the water conservation program. The research and establishment of landscape water budgets for homeowner associations and commercial properties would be a valuable tool for existing properties that are not affected by the revision of the Landscape Section of the Town Code. Other goals include the development of a water conservation education program for children. Education of children at an early age where behaviors are still being developed can have the greatest impact. A youth conservation education program would allow the water utility to r sponsor water education programs in elementary schools located within Oro Valley. L -30- WATER UTILITY OPERATIONS Production Facilities Division Water Utility personnel in the Production Facilities Division are responsible for the operation and maintenance of the wells, booster pumps and reservoirs on two potable water distribution systems and the booster pumps, metering stations and reservoir on the reclaimed water delivery system. All Production Facilities personnel are operators licensed and certified by the Arizona Department of Environmental Quality (ADEQ). The operators have the direct responsibility to operate the facilities section of the water systems according to the regulations and rules set forth by the EPA (40CFRI41) and ADEQ (Arizona Administrative Code Title 18). More information can be viewed regarding water quality and water systems at the ADEQ website at www.azdeq.gov. The potable systems are chlorinated systems and the Production Facilities Division controls and monitors the chlorine dosage rates and residuals on a daily basis. The potable system located within the Town of Oro Valley Water Service Area (OVWSA) is a Grade IV Water Distribution and a Grade II Water Treatment system and currently delivers water to twenty pressure zones and a consecutive system located at La Cholla Air Park (LCAP). LCAP is considered a consecutive system because it is served off of the OVWSA through a large 6-inch meter and the Water Utility does not have responsibility for the operation and maintenance of the LCAP water distribution system. The Public Water System Number is AZ0410164 for OVWSA. The potable system that is not located within the Town boundaries, known as the Countryside Water Service Area (CSWSA), is a Grade III Water Distribution system that currently delivers water to a single pressure zone at the Countryside development. The Public Water System Number is AZ0410175 for CSWSA. The groundwater production capacity within the OVWSA is currently 15.34 million gallons per day (10,652 gpm) with a storage capacity of 10.70 million gallons. The groundwater production capacity within the CSWSA is currently 2.59 million gallons per day (1,796 gpm) with a storage capacity of 0.87 million gallons. Production Facility Operations The Production Facility Staff continue to be proactive in the implementation of facility upgrades and a preventive maintenance program. Facility sites are evaluated annually to determine necessary upgrades to ensure efficient operation of the facilities. A continuing effort to retrofit water level sensing equipment in each production well will help the Utility collect monthly water level data and will assist in the development of an accurate water level database and to analyze trends. Monthly monitoring of the water levels will also help the Utility identify potential problems with either the pumping unit and/or the well itself and schedule required maintenance before a well and/or pumps fail. -31- Production Facility Operations The following are some of the major activities and accomplishments that were performed by the Production Facilities Division in CY 2011: ➢ ADEQ Sanitary Survey on System 10-175. There were no violations ➢ Reorganized and submitted Area wide AZPDES De Minimis General Permit ➢ Assisted with the commissioning of the La Canada 3MG reservoir ➢ Responded to and minimized impact on systems from low ambient temperatures on February 2nd and 3' . 50+ system wide repairs and 30+ preventative measures.

It The Supervisory Control and Data Acquisition (SCADA) system is continuously updated, improved and programmed to streamline operational control, data trending, and alarm annunciation. The SCADA system, a centralized industrial network, currently monitors and controls all potable and reclaimed system facility sites. Utility staff monitors and operate all water systems via the SCADA system on a twenty four hour seven day a week (24/7) basis. Production facilities staff is also responsible for the installation and maintenance of security devices at the Utility's facilities. Production staff works very closely with Distribution Facilities and Water Quality personnel to address any system problems. The Production Facilities staff is on -call 24/7 and utilizes a tiered level after-hours response protocol that is in accordance with the developed Emergency Response Plan. Production staff is continually monitoring and checking the system to provide safe and reliable water service for our customers. DDistribution Facilities Division Utility personnel in the Distribution Facilities Division are responsible for the operation and maintenance of 341.55 miles of potable water main, 12.5 miles of reclaimed water mains for a combined total of 354 miles of water mains. There are approximately 2,035 fire hydrants and 7,453 valves on the water distribution system. All Distribution Facilities personnel are operators licensed and certified by the Arizona Department of Environmental Quality �� (ADEQ). The operators have the direct responsibility to operate the distribution section of the water systems according to the regulations and rules set forth by the EPA (40CFRI41) and nADEQ (Arizona Administrative Code Title 18). The staff conducts maintenance programs � and repairs that keep the distribution system functioning properly and minimizes problems that are inherent to water distribution systems. Data bases have been established for hydrants; pressure reducing valves, and air release valves. A valve exercising program that helps monitor equipment and develop maintenance cycles has been established. The program provides information and equipment history data that facilitate a proactive replacement program. The Division works closely with Customer Service and responds to complex customer work orders such as high/low pressure, water quality, service line breaks, hydrant repairs, system pressure regulating valves, system air relief valves and system flushing. The Division also is responsible for bluestaking all underground water mains. The Division is responsible for maintaining 15 active and 7 inactive pressure reducing valves (PRV) for a total of 22 PRVs, 749 air relief and 878 drain valve assemblies. The Division also responds to water pipeline leaks and repairs these leaks in a timely and cost effective manner to minimize impacts to our customers. The Division also works with local fire protection agencies to flow test and repair approximately 38 fire hydrants. The following are some of the major activities and accomplishments that were performed by the Distribution Facilities Division in CY 2011: a ➢ Maintained, replaced and/or repaired 25 fire hydrants ➢ Flow tested 3 8 fire hydrants for fire protection ➢ Performed 100 tests and/or repairs for the maintenance and operation of the 22 pressure reducing valves ➢ Maintained, replaced and/or repaired 14 air relief valves ➢ Maintained, replaced and/or repaired 2 drain valve assemblies ➢ Performed 2,881 Bluestakes for underground pipeline and facilities locations ➢ Responded to and repaired 1 water pipeline break ➢ Responded to 432 customer inquiries in the field ➢ Responded to and repaired 35 service line breaks ➢ Responded to 139 after hour call outs ➢ Installed 13 new hydrant defenders ➢ Modified 2 pressure reducing valves The Distribution Division also has significant direct customer contact and responds to customers regarding pressure or flow related problems in the field. The Distribution Division, in conjunction with the Production Facilities Division, the 24-hour on -call staffing to respond to water system problems. The Distribution staff received numerous letters from customers who received assistance from Distribution personnel that exceeded their expectations. This is confirmation of the high level of professional performance and courteous service provided by Utility personnel. i -34- SECURITY AND EMERGENCY RESPONSE PLAN The Public Health Security and Bioterrorism Preparedness and Response Act were enacted in 2002. This federal mandate required the Utility to perform a Vulnerability Assessment (VA) and develop an Emergency Response Plan (ERP) that incorporates the vulnerabilities identified by the VA. Under Homeland Security Presidential Directive No. 7 (HSPD7) the Water Utility infrastructure is considered critical infrastructure of national interest. Under current Federal guidelines, water operations personnel are considered first responders. Though primarily mandated by State rules with public health responsibilities, water operators also have a public safety responsibility with relevance to the water systems they are charged with operating. First response staff and vehicles are placed in an after hours position to directly respond to any developing emergency in order to minimize a situational effect on water system integrity. Production Facilities and Distribution Facilities staffs coordinate their response actions and will respond with an appropriate level of personnel to mitigate the problem. Currently, the combined first response staff from Distribution and Production can handle the initial stages of two small-scale concurrent system events or one widespread system event. Any facilities security situations directly involve the Oro Valley Police Department as a first response action. The VA and the ERP were submitted in 2004 and are reviewed annually. In 2011, Utility personnel, with the assistance of a security consultant, reviewed, refined and updated the security program, Emergency Response Plan, and the Business Continuity Plan (BCP). The ERP and BCP are currently up to date regarding the Utility operational or response situations, contact information and procedures. The changes are designed to protect and "harden" the facilities against potential threats from the acts of people who wish to do harm to the residents of Oro Valley. In 2011, under the security program, a series of training classes and exercises were made available and completed by the Utility Staff. This training is done on an annual basis as per the guidelines from the Department of Homeland Security, FEMA, and the EPA. Utility personnel will continue to complete the required training and certification for Incident Management courses provided by FEMA. Operations personnel also receive emergency management courses provided by ADEQ. The Utility will continue to implement the elements defined in the VA, ERP and the BCP as well as those that may be identified through the course of business. The hydrant lock program continues to be implemented through the new development process and all hydrants within Oro Valley systems are protected from illegal entry and use. In 2011, 13 new hydrant defenders and locks were installed. There is extensive cooperation under this program with the three fire districts serving Oro Valley water Utility customers, the Oro Valley Police Department, and other area water providers. Security features, which include perimeter fencing, security walls, warning signage, motion sensors and cameras at all active production facilities were inspected to maintain integrity. -35- C C The Water Utility also has the equipment and capability to test water samples under a first response scenario. A continuing program has been initiated to chemically characterize r ("fingerprint") the water produced. This will help identify any anomalies during a suspected L event involving water quality. These baseline data are taken on a monthly basis. The Utility is kept abreast of local, regional and national security issues via weekly situation L reports provided by Water Information Sharing and Analysis Center (Water ISAC). The Utility is also a member of the Arizona Water/Wastewater Agency Response Network (� (AZWARN) which mutually cooperates with other water and wastewater providers in an L emergency. L -36- ENGINEERING AND PLANNING The Engineering and Planning Division is responsible for planning and managing the design, construction and inspection of all new water infrastructures for the Town of Oro Valley as well as planning for the delivery of new water resources to the Town. New water infrastructure is constructed both through the new development process where the developer finances the project and through the Water Utility's capital improvement program. The Engineering and Planning Division provides technical support to both operational groups, Distribution and Production as well as to other Water Utility personnel. Additionally, it is responsible for managing and maintaining a Geographic Information System data base on all existing water system infrastructure in coordination with the Information Technology Department. As part of the long-term plan to deliver CAP water to the Town in January 2012, the Engineering and Planning Division worked with two engineering firms, CH2MHILL and Westland Resources. They completed the studies for the water quality, treatment and distribution of CAP water to the Town of Oro Valley. The study looked at two options to delivering CAP water to the Town. One option was to deliver treated CAP water from a treatment facility constructed in the general area of Tangerine Road and the I-10 freeway next to the CAP canal. The second option was to deliver our CAP water to Tucson Water's recharge and recovery facilities and then have them deliver it through their water system to us through their Naranja Reservoir and Booster station located at Shannon Road and Naranja Road on the west side of the Town. The second option, using Tucson Water to deliver (wheel) our CAP water to the Oro Valley Water Service Area, was selected based on the cost and the short amount of time required for implementing the delivery. The water quality studied under this option was found to be compatible with the Town's groundwater and with very few differences. The Town selected 1500 acre feet per year as the first phase and initial amount for delivery of our CAP water allocation. The Town worked with Tucson Water to structure an IGA that would make this delivery possible. The Town paid for all of the capital costs of the infrastructure required to deliver the water which included the addition of a new pump and related mechanical and electrical equipment at TW's reservoir site and approximately 900 feet of 16-inch pipeline to connect to the Town's water system. New Development The New Development Section is responsible for facilitating development by reviewing and approving water improvement plans for proposed new developments and assisting with planning for future water system expansion. Water improvement plans are reviewed for compliance with Water Utility standards and are approved for construction once all requirements are met. Through this process the need for additional pipelines, booster pump stations and water storage reservoirs are identified as they relate to future developments. Each new development project is required to have an executed Line Extension Agreement (LEA) which outlines the responsibilities of the developer and the Town of Oro Valley. The LEA is the legal document that transfers the ownership of the new infrastructure to the Town and provides a two year warranty for the new water infrastructure installed. The New Development Section works closely with the Pima County Department of Environmental Quality to acquire a certificate for the "Approval of Construction" prior to placing new water facilities in service. Coordination with Development and Infrastructure Services Department is critical to this process to ensure quality construction and that water facilities are constructed in accordance with approved standards. In 2011, the New Development Section reviewed and approved 10 water improvement plans for construction. Seven plans were constructed, inspected, approved as -built, and placed into service. The completion, of these New Development projects added approximately 1.75 additional miles of pipeline to the existing water distribution system. Construction Inspection All new development and capital projects are inspected during construction for conformance with the approved design as well as material and installation standards. The Water Utility has two full time Construction Inspectors and utilizes the services of .a consultant inspector to assist when specialized inspections are required. In addition to inspecting new construction, both inspectors assist Operations Staff in the monitoring and inspection of existing water main repairs. In 2011, inspections were performed on 7 new development projects and 4 capital improvement projects. These projects included potable water system pipeline, the construction completion of a 3 million gallon concrete in -ground reservoir and the start of a new booster station. Due to the decline in new development projects, Water Utility inspectors were available to inspect all of the Utility's capital improvement projects typically performed by outside consultant inspectors for a savings to the Water Utility. CAPITAL PROJECTS The Engineering and Planning Division manages the design and construction of capital projects that are identified in our five-year capital program and annual operating budget. These projects are designed to improve existing facilities to maintain current levels of service. These capital projects are described below. Design Projects The Chlorine Storage Facility Project located at the reclaimed water facility site and the Campo Bello water main designs are complete. Construction of these projects will commence in spring of 2012. In 2012 design projects include Tangerine Hills to replace existing valves and install fire hydrants. We will start preliminary design to wheel an additional 1,500 acre feet per year (for a total of 3000 acre feet per year) of CAP water through the Tucson Water System. Planning Studies Three CAP water studies that were completed during 2011 are as follows: 1. CAP Water. Distribution and Delivery Study 2. CAP Delivery Cost Study 3. CAP Delivery Cost Study - Recharge and Recovery at Red Rock -3 8- In FY 2012-13 we will study the blending of groundwater and CAP water to further reduce total dissolved solids and hardness. Another study will evaluate the potential of delivering CAP water through the Oracle Road corridor and possibly the Countryside water service area. Construction Projects El Conquistador C-D Zone Booster Pump Station Reconstruction of the El Conquistador C-D Zone Booster Pump Station started in 2011 and will be completed in March 2012. The existing facility has been in operation since the early 1980's and is located near El Conquistador Way and Oracle Road. The new facility will have pumps designed to improve system capacity and efficiency. This project is financed through a low interest loan from the Arizona Water Infrastructure Finance Authority (WIFA). El Conquistador C-D Zone Booster Pump station Construction La Canada 24-Inch Water Main The project was completed May of 2011. The water main is located along La Canada Drive and Moore Road. The 24 inch water main connects the new 3.0 million gallon La Canada Reservoir to the distribution system. North La Canada Reservoir The North La Canada Reservoir is a 3.0 million gallon concrete buried reservoir that was completed in November 2011. It is located near Moore Road and King Air Drive. The project includes an in -ground valve vault and provision to add a second reservoir and a booster pump station in the future. It is the largest potable water reservoir in the Town. This project has proven to be very beneficial to the water system, specifically for needed reservoir storage and the delivery of our CAP water. -39- tag•. 71 t {,� ♦ ' '`., 3 #i *Fy •'� R `q..

Well E-1 B Lambert Lane Water Improvements To date the Town has installed over 3,500 feet of new 16-inch water main as part of the Lambert Lane road widening project. The project calls for the installation of 7,000 feet of new water main. The project is scheduled for completion September 2012. The road improvement will continue through 2012 with completion in 2013. -40- Interim Delivery of CAP Water through Tucson Water Interconnect. The project was constructed to deliver our CAP water through the Tucson Water system. A new pump and controls were added to the Tucson Water Naranja facility that were designed and constructed by Tucson Water. Oro Valley Water Utility installed over 900 feet of 16 inch pipe on Vista Del Sol to connect to the Tucson Water system. Tucson Water and Oro Valley Water worked cooperatively to complete the project. The project was completed and placed in service on January 24, 2012. Oro Valley's CAP Water Pipeline Installation Future Projects Oro Valley CAP Pump and Discharge Pipeline at Tucson Water's Naranja Reservoir Site Potable water capital improvement projects planned for FY 2012-13 include the following: ➢ Construct water main replacement in the Campo Bello Subdivision ➢ Construct the RV Chlorine Storage Facility ➢ Replace 10 flow meters at various well sites ➢ Install control valve and flow meter at High Mesa facility ➢ Install hydrants and replace valves in the Tangerine Hills subdivision ➢ Install pressure reducing valves on Naranja and Palisades ➢ Finish the Lambert Lane water improvement project ➢ Begin installation of Advanced Metering Infrastructure in the Oro Valley Water Service Area Construction costs have stabilized in the past twelve months and we are expecting a slight increase in next fiscal year. Five Year Capital Projects Program The following table summarizes the Utility's proposed five year Capital Projects Program. A detailed schedule of the program may be found in Appendix D.

It is proposed that projects in future years will be cash funded and/or debt financed through loan or bond proceeds. -42- FINANCIAL HIGHLIGHTS The Utility's revenue consists of potable and reclaimed water sales, groundwater preservation fees, miscellaneous service fees and charges, water development impact fees and interest income. The Water Utility has three funds: ➢ The Enterprise Fund provides funding for the Water Utility administration and operations as well as existing system improvements. The sources of revenue for this fund are water sales and service charges. ➢ The Potable Water System Development Impact Fee Fund provides funding for expansion related projects for new growth. The source of revenue for this fund is potable water development impact fees. These fees are paid at the time a meter is purchased. The funds collected ensure that system expansion is paid for by new development. ➢ The Alternative Water Resources Development Impact Fee Fund provides funding for the development of renewable sources of water supply, specifically reclaimed water and CAP water and any infrastructure required for delivery of those resources. The sources of revenues for this fund are impact fees and Groundwater Preservation Fees (GPF). Alternative water resources development impact fees are paid by new development for that portion of renewable water supply and infrastructure attributed to new growth. The GPF is paid by existing customers for their portion of renewable water supply and related infrastructure. The following table contains the actual revenue received for FY 2010-11 for all funds within the Utility: Revenue Source Amount Received Potable Water Sales: Residential $ 89030,770 Commercial $ 9119914 Irrigation $ 19162,574 Turf $ 147,424 Construction $ 979052 Reclaimed Water Sales: Turf $ 196569707 Construction $ 815 Irrigation $ 139258 Misc.

The Water Utility and Fin ance Department will continue to review bonds and debt service to look for g opportunitles to reduce debt obligations when it is fiscally sound and there is a financial g benefit. By reducingoutstanding debt, it will be easier to maintain the required 1.30 debt service coverage requirement which may result in smaller rate increases. -44- WATER RATES AND DEVELOPMENT FEES The functions and duties of the Commission include reviewing and developing recommendations for water revenue requirements, water rates and fee structures. The Commission annually evaluates staff recommendations based on a water rates analysis to assure the recommendations meet Town policies and bond covenants. The Utility bases its financial analysis on the American Water Works Association (AWWA) Cash Needs Approach. In 2011 the Town Council did not consider a water rate increase because, after reviewing the Water Rates Analysis Report prepared by staff, the Water Utility Commission determined no increases in water rates or service charges were required. However, on November 17, 2010 an increase in the Groundwater Preservation Fees (GPF) was approved and adopted by Town Council that deferred the effective date of the increase until October 1, 2011. For potable water use the GPF increased by $0.20 from $0.75 to $0.95 per 1,000 gallons. For reclaimed water use, the GPF increased by $0.10 from $0.40 to $0.50 per 1,000 gallons. The average residential customer using 8,000 gallons of water experienced an increase of 4.1 % or approximately $1.60 per month. All current water rates fees and charges are available to view on the Town website at htto •//www orovalleyaz ov/Town Government/WaterUtility/Water Rates and Fees.htm The Alternative Water Resources Development Impact Fees were last increased in December 2008 and the Potable Water System Development Impact Fees were increased in September 2007. The cur rent impact fees are also on the Water Utility website and the Town website in the Town Code — Chapter 15 Water Code. Each year, on or before September 28th, an �. accounting of the water development impact fees is presented in a report required by Arizona Statute and is available for public review. In accordance with Mayor and Council Policy, a Water Rates Analysis Report will be d during 2012 that contains information on the three funds that comprise the Oro prepared g • Valley Water Utility. Each fund is individually analyzed with regard to revenue and revenue p requirements. It is anticipated that the Water Rates Analysis Report will be completed in September of 2012 and reviewed by the Water Utility Commission shortly thereafter. If, after ' receiving the recommendation of the Commission, the Council approves a Notice of Intent to increase water rates or fees, a public hearing date will be set to review and consider the recommended increases and hear comments from residents and customers. Council action on water rates will be taken only after that public hearing. -45- YEAR 2009 2010 2011 Customer Base 181401 185474 181545 Water Deliveries in Gallons 2,492,488,000 2,358,509,000 2,3951142,000 Reclaimed Water Deliveries in Gallons 637,1327000 637,690,000 735,065,000 Bluestakes 35389 31127 2,880 Customer Contacts Customer Service 37,430 331323 33718 Field Operations 3,616 31557 5,290 Water Conservation -Audits 179 178 119 Water Quality Samples 4,491 5,891 21969 Meter Reads 2147530 2201098 2191973 Billing Collection Rate 99.84% 99.59% 99.83% A-1 A-2 A-3 A-4 138503130,000 $964,; Accounts By User Type As of December 31, 2011 17,675 Gallons Sold By User Type January -December 2011 255,0081000 55,000 Revenue By User Type January -December 2011 $8,039,133 $128,141 �1,665,007 A-5 11136,752 ■ Construction - 1 % ❑ Commercial - 2% ■ Residential - 95% ■ Irrigation - 2% • Reclaimed - 0% ■ Potable Turf - 0% ■ Construction - 0% ❑Commercial - 7% ■ Residential - 59% ■ Irrigation - 8% • Reclaimed - 24% ■ Potable Turf - 2% ■ Construction - 1 % ❑ Commercial - 8% ■ Residential - 67% ■ Irrigation - 9% Reclaimed - 14% ■ Potable Turf - 1 % cyj ca CIO a) C13 C13 C:) < .......... ---------------- CO CLI r14 in L. in C CA C:p C> ci C)p C? � i'74 R= ICDI wn %r swipiv In pead t O J PLLEY O� 29 lip SOUND ED �g3 44 TOWN OF ORO VALLEY WATER UTILITY COMMISSION 2012 ANNUAL REPORT APPENDIX B WATER QUALITY (I`- c O O U)C C ca � O >, t O N 0 Z w O Z O J Q W Q J F- LU H Q W J _!
