EXECUTIVE SUMMARY
TOWN OF ORO VALLEY
WATER UTILITY COMMISSION
ANNUAL REPORT
APRIL 2013
In October 1996 the Oro Valley Town Council (Mayor and Council) formed the Oro Valley
Water Utility Commission (Commission) to act as the official advisory body to the Mayor
and Council regarding water related issues. The Commission is required to prepare an annual
report to the Mayor and Council each year. This report is the Commission's seventeenth
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 (FY) ending June 30, 2012 and calendar year (CY) 2012.
CUSTOMER SERVICE
The Town of Oro Valley Water Utility (Water Utility or Utility) has 18,716 customer
connections serving a population of 42,694. This includes both the customers within the
Town boundaries and the Countryside area. The Utility installed 171 new water connections
in CY 2012, a 0.92% growth rate. Approximately 2.27 billion gallons (6,956 acre feet) of
potable water was delivered to our customers. In addition, approximately 684 million gallons
(2,099 acre feet) of reclaimed water was delivered for golf course irrigation and other uses.
WATER QUALITY
For the eleventh consecutive year, the Utility is proud to report that it did not experience any
water quality violations. The number of tests performed in CY 2012 was 2,250 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.
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 is delivered to the Oro Valley
potable water system through Tucson Water's Distribution System. Reclaimed water is used
for turf irrigation and is delivered through a separate reclaimed water distribution system.
Oro Valley also uses its CAP water indirectly through groundwater storage credits.
Groundwater levels continue to decline in the Oro Valley aquifer but to a significantly lesser
extent than in previous years because of the decrease in groundwater pumping. Operation of
the reclaimed water system and the delivery of CAP water have slowed the groundwater
decline, thus conserving, preserving and protecting our aquifer and our groundwater supply.
Plans for future use of our remaining CAP water allocation are being developed.
-4-
In CY 2012, the Utility pumped 6,161 acre feet (2 billion gallons) of groundwater from its
wells. The wells in the Oro Valley Water Service Area produced 5,415 acre feet (1.76 billion
gallons) and the wells in the Countryside Water Service Area produced 746 acre feet (243
million gallons). This total pumped from our wells is 1573 acre feet (513 million gallons)
less than in 2011. This reduction is due to our CAP deliveries and water conservation efforts
in 2012. Well water levels declined an average of 1.29 feet in the Oro Valley Water Service
Area and declined 2.75 feet in the Countryside Water Service Area in CY 2012.
In 2012, the Utility also delivered 1,283 acre feet (418 million gallons) of its CAP through a
wheeling agreement with Tucson Water. The Utility also stored CAP water through an
agreement with Kai Farms and through permits to store in Central Arizona Water
Conservation District recharge projects to obtain groundwater storage credits within the
Tucson Active Management Area. The use of our existing groundwater allowance account
and groundwater storage credits reduces our obligations to the Central Arizona Groundwater
Replenishment District.

The Water Conservation Program continues to be a vital asset in assisting the Utility to
achieve its overall water management goals. In 2012, 144 water audits were performed. Since
the program's inception in 2003, participating customers received 1,630 free water audits,
which saved our customers both water and money.
The Utility encourages water conservation by educating our customers. A Youth Water
Conservation Education Program for elementary schools in Oro Valley is currently being
developed. This program will be implemented in the fall of 2013.

FINANCIAL HIGHLIGHTS, WATER RATES AND 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 2012, 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
2012.
The Utility continues to be fiscally sound with cash reserve at 35% of the annual budget.
Water rates include a Groundwater Preservation Fee which is used to fund the development
of our renewable reclaimed and CAP water supplies. Water development impact fees, which
fund expansion of the water delivery system, have been collected to ensure that growth pays
its fair share. In 2012, the Utility further reduced its debt obligations and annual debt service
through refinancing and paying off principal.
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.
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 mmorovalley,�gov/Town_Government/waterUtility

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 18,716 water service connections serving 42,694 people.
The Utility has grown over the past year and in 2012 an additional 171 meters were installed
for a growth rate of 0.92%. Over 4,947 customer accounts were changed in 2012, primarily
due to opening and closing of accounts for new move -ins and winter residents. In 2012 the
Utility delivered:
• 2.27 billion gallons (6,956 acre feet) of potable water
• 684 million gallons (2,099 acre feet) of reclaimed water for irrigation to five golf
courses and a school athletic field.
• Combined total of 2.99 billion gallons (9,055 acre feet) of water delivered and billed
to our customers.
The Customer Service Division mailed and processed 222,304 bills and 12,216 delinquent
notices to our customers during calendar year 2012. The Customer Service Division responds
to customer concerns that arise from the operation and management of the water system and
in 2012 responded to 31,437 customer contacts averaging 127 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. Providing professional and courteous service is paramount to the
successful operations of the Water Utility.
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's 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 the ability to view the current water bill, billing and payment information as
well as a two year history of water usage. The Utility provides convenient alternative
payment methods for our customers. During 2012, the Utility received $1.5 million in credit
card payments. Credit card and other payment options are listed below:
• Toll free telephone number via IVR (Interactive Voice Response) that accepts credit
cards for payment
• Online credit card payments accepted at the Water -on -the -Web site.
-7-
• Credit card payments accepted at the Utility office.
• Automated Clearing House (ACH) automatically pays the customer's water bill on
the due date and is deducted from their checking or savings account. There are
currently 4,336 customers enrolled in this program. This represents 23% of our
customer base.
• EFT (Bank to Bank transfer of payment funds). This "paperless" form of online
payments is received 1 week faster than traditional paper checks.
• QR (Quick Response) Code for customers with a Smart Phone that includes the toll L
free telephone number for quick easy credit card payments
To enhance customer service and to decrease 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, 1270 customers are enrolled in this program. L
As part of the 2011 AMI (Advanced Metering Infrastructure) project, F1exNet software r
continues to enable 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.
Where Advanced Metering Infrastructure is installed in the Countryside Water Service Area,
F1exNet software facilitates the monitoring of leaks on a daily basis. Utility Operators
provide early leak notification to our customers that ultimately save them money and
conserves water wasted by leaks that are not discovered and repaired in a timely manner.
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. AMI permits the staff to read
meters from our office and provides us the ability to obtain billing reads on the same day
each month. The Utility will begin AMI installation in the Oro Valley Water Service Area in
2013.
As the Customer Service Division looks to the future they will be selecting new technology
to streamline procedures and increase efficiencies. Utilizing computer tablet technology, staff
is now electronically sending and distributing work orders, service requests, and new and
closed account paperwork from CSRs to the Utility Operators. Employing this technology
has reduced staff travel time, wear and tear on vehicles and gasoline and has resulted in
higher efficiency and productivity.
In 2013 the Utility will be launching a customer web portal. Once a customer is enrolled in
the on-line service, they will be able to view their water use on an hourly, daily, weekly or
monthly basis. They will also be able to tailor personal notifications based on their individual
needs. The web portal is scheduled for launch in April of 2013 for the Countryside Water
Service Area.
Utility statistics including new meter installations, customer contacts, and water deliveries
for CY 2012 may be found in Appendix A.

METERS DIVISION
Advanced Metering Infrastructure Project
The Meters Division team started 2012 with great enthusiasm. In the Countryside service
area, the Advanced Metering Infrastructure (AMI) project and meter replacement program
was completed and in full operation. In addition to the centralized equipment and antenna,
over 2,200 meters were installed to facilitate electronic meter reading capabilities. The AMI
project and meter replacement program provides for more accurate measurements of water
usage and also assures that the volume of water billed is accurate. Additionally, the
technology provides an opportunity to use existing resources more efficiently. The Meters
team will now redirect their focus and capabilities to other responsibilities such as customer
work orders, meter box cleaning, angle meter stop repairs, and meter testing procedures. The
insight, knowledge, and experience gained from the project will help the team prepare for the
next phase of the AMI project.
Using AMI technology provides customers with accurate and complete water use
information. With AMI and FlexNet software, staff can review water use history on an
hourly, daily, weekly or monthly basis. This is extremely valuable in assisting our customers.
Understanding the benefits and efficiencies gained by using AMI, the Meters Division is
excited about expanding this technology into the Oro Valley service area. In 2013, the team
is continuing with the AMI and the meter replacement program. There are approximately
2900 meters scheduled for change out within the next phase.
As the project starts, the Meters Division team will work closely with external contractors
and take the lead role in organizing, planning, and scheduling work. In addition, existing
team members will actively participate in the programming of new electronic meters and
getting the units ready for operation. This is a team effort with high expectations and the
Meters Division team is looking forward to the challenge.
Automated Meter Reading Project
Due to the projected timeline of the AMI project in Oro Valley, the Meters Division team is
continuing with Automated Meter Reading (AMR) equipment in the Stone Canyon service
area. Stone Canyon is located in a mountainous region that will not be accessible with the
AMI planned for the Oro Valley service area. In 2013, the team will install AMR equipment
in the Stone Canyon area. 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 for
billing.
Technological Advancements
In 2012, the Meters Division team was excited about using advanced handheld equipment.
The technological advancement with the AMI project prompted the water utility to
incorporate the use of computer tablets.
-9-
These tablets allow the Meters Division team to generate or close work orders, receive and
send reports, view real time customer usage, and verify delinquent account payments in the
field.
This coming year will also have opportunities for implementing more technology. In addition C_
to the continued benefits and capabilities of the AMI project in Oro Valley, team members
are getting advanced handheld units for manual reading capability. These advanced handheld
units will also be capable of data logging, scanning, troubleshooting, and programming that
currently require multiple devices. These units have all the necessary features required to
work on both AMI and AMR equipment. r
L
The team will operate more efficiently and increase productivity with these two technologies
since there will no longer be a need to return to a central location and get the required
equipment.

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.
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.
In 2012 the Utility received 2,250 analytical results for required water sampling and
operational data. 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 required
by ADEQ. These stations are located in neighborhoods throughout the water distribution
system specifically selected to represent the water quality that is delivered to our customers.
The Utility also has an additional twenty-nine sampling stations that can be used during
emergencies and to meet future testing requirements. A new water quality sampling station
was installed where our CAP water is delivered from the Tucson Water system. 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.azdey.,,�,Yov. The Town's water
system is in full compliance with all State and Federal regulations.
-11-
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 by ADEQ 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. Additionally, comprehensive emergency plans have been developed to
ensure an immediate response to any adverse water situation.
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.
Detection of a contaminant in drinking water does not necessarily represent a threat to public
health. Due to current technology, water utilities are now able 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
a level of 0.2 to 0.8 parts per million (ppm), as a precaution against bacterial growth. The
Total Coliform bacteria group is used as an indicator to more closely monitor the distribution
system for possible unwanted bacteria. During 2012, the Utility collected 696 samples for
analysis of Total Coliform bacteria, all samples were negative for bacteria. This is a direct
result of a successful disinfection program, effective system monitoring, proficient sampling
methods, and routine maintenance.
The Utility regularly receives inquiries concerning water hardness. Water hardness is a
measurement of the concentration of calcium and magnesium. During CY 2012, the hardness
levels in Oro Valley range from 1.8 to 12.0 grains per gallon. On average our water quality is
in the soft to moderately hard range, which is considered acceptable.
Water quality standards are continually researched and regularly modified and changed based
on scientific research.
-12-
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, 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 for lead and copper were 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
Oro Valley is a growing community in an and 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.
-13-
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-B115, 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 1,271 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:
➢ 158 backflow assemblies owned by the Town of Oro Valley were tested
➢ 57 repairs on in ground and construction water backflow prevention assemblies
➢ 46 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.

CURRENT WATER SUPPLY
Developed Water Resources
• Groundwater: 13,384 acre feet per year
• CAP Water: 1,500 acre feet per year
• Reclaimed water: 2,500 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 2012, Oro Valley pumped 6,161 acre feet of groundwater from our wells and aquifer. This
total is 1,573 acre feet less groundwater pumping from our wells due to our CAP water
deliveries and water conservation. The wells in the Oro Valley Water Service Area produced
5415 acre feet and the wells in the Countryside Water Service Area produced 746 acre feet.
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 and the recent delivery of our CAP water has significantly reduced
our obligations to the CAGRD.
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 June 18 for the OVWSA and on June 10 for the CSWSA.

Groundwater studies indicate that the Oro Valley aquifer has a sustainable groundwater
production rate of approximately 5,500 acre feet per year. In 2012, Oro Valley pumped 6,161
acre feet of groundwater. This resulted in pumping our wells 661 acre feet more than the
sustainable groundwater production rate for our wells. In the OVWSA, the average annual
well water level decline for the last 5 years is 1.76 feet and for calendar year 2012 there was
an average well water level decline of 1.29 feet. For wells in the CSWSA, the average annual
well water level decline for the last 5 years is 1.54 feet and for calendar year 2012 there was
an average well water decline of 2.75 feet. For all wells, water level changes in CY 2012
ranged from a decline of 12.1 feet to a rise of 8.8 feet.

The use and development of our renewable water resources in 2012 has reduced our reliance
on groundwater. The use of reclaimed water since October of 2005 has helped to reduce the
impact on the Oro Valley aquifer over the last seven 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).
Groundwater pumping has been further reduced this year through the delivery of 1,283
acre-feet (418 million gallons) of our CAP water under a wheeling agreement with Tucson
Water.
Future development of these renewable water resources will further reduced our groundwater
production and will help achieve our goal of protecting and preserving our aquifer.
-16-
Undeveloped Water Resources
• Central Arizona Project Water: 8,805 acre feet per year
• Long -Term Storage Credits: 10,380 acre feet
• Ground Water Allowance Account: 13,700 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. On January 24, 2012, deliveries of our CAP water through a connection to the
Tucson Water system began. In 2012, 1,283 acre feet of our CAP water were 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 directly deliver or directly recover this remaining amount of our
CAP water. However, we continue to recharge our CAP water for groundwater storage
credits which are used for replacing groundwater depletions from our recovery wells. The
J development of our remaining CAP water will be paced based upon our water demands,
aquifer conditions and new growth.
1 The Utility has obtained permits to store CAP water at the various recharge facilities listed
� below and has stored the following amounts in 2012.
• Kai Farms, 2,500 acre feet
• Lower Santa Cruz Replenishment Project, 0 acre feet
• Pima Mine Road Recharge Project 500 acre feet
• Central Avra Valley Storage and Recovery Project 200 acre feet
• Southern Avra Valley Storage and Recovery Project 0 acre feet
• Total amount stored in 2012 5,000 acre feet
The Utility will continue to recharge CAP water for use at our recovery wells and to build
long-term storage credits until such time the water is needed for future delivery.
In addition to our long-term storage credits, our Groundwater Allowance Account (GWA)
J 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. Additional purchases of GECs will be evaluated
and considered in the future to increase the balance of the Groundwater Allowance Account.
-17-
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 2,099 acre feet of reclaimed water in 2012.
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.
In 2013, the Utility will evaluate if interruptible reclaimed water service from Tucson Water
is feasible. The Reclaimed IGA will also be reviewed for any other potential changes.
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 2013.
-18-
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. On 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 renewable 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 possibly acquire additional water
supply from the Colorado River. This includes review of the available CAP Non -Indian
Agricultural Water and a state wide effort known as the ADD Water Program (Acquire,
Develop and Deliver).
These potential water acquisitions will involve numerous water providers, the Central
Arizona Project, the Arizona Department of Water Resources and the U.S. Bureau of
Reclamation. The Utility will evaluate our future needs in applying or participating in these
programs.
Potable Water System
The potable water system improvements are included in the Fifteen Year Capital Projects
Program. The demand on our wells has been significantly reduced due to use of reclaimed
water for irrigation and the delivery of our CAP water through the Tucson Water system. 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 Central
Arizona Groundwater Replenishment District (CAGRD).
Our aquifer has benefited from the development of our renewable water and because water
levels are decreasing less, we have been able to acquire more recovery wells.
-19-
These additional recovery wells were permitted by the Arizona Department of Water
Resources in 2012 and will further reduce our reliance on the CAGRD.
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. In addition, non -turf irrigation uses such as
landscape irrigation, construction water, dust control and street cleaning 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 has executed an Intergovernmental Agreement with the City of Tucson to deliver
a portion of the Town's CAP water wheeled through the Tucson Water system via a
connection to the Oro Valley Water Utility system. This project started deliveries of our CAP
water on January 24, 2012 and benefits our aquifer by reducing groundwater pumping. This
is a regionally cooperative project that was nominated for an award by the Metropolitan Pima
Alliance in 2012.
OVWU has also been cooperating with Metropolitan Domestic Water Improvement District,
Flowing Wells Irrigation District, and the Town of Marana to study opportunities to develop
our CAP water. The Utility has developed studies that look at various alternatives and the
associated costs for future delivery of our CAP water.
The IGA with Tucson 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. 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" (actual) water
deliveries of renewable CAP water and reduces its reliance on groundwater.
Oro Valley's CAP water is delivered from the CAP canal and 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 were installed by Oro Valley to deliver its CAP water to the Oro Valley water
distribution system. All water is accurately metered and accounted for billing purposes and to
assure delivery volumes.
-20-
Oro Valley Central Arizona Project Water Connection
Pipeline and Dedication Celebration
In the short term, OVWU will also work with Tucson Water to increase deliveries of our
CAP water in accordance with our IGA. 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.
The short-term development of a portion of our CAP water provides financial benefit to our
customers in that it defers significant expense to develop a major capital project.
Additionally since the short-term costs were relatively lower capital expenditures, it could
also lower our capital expenditures when we develop our remaining CAP water in the future.
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. Regional cooperation to develop our CAP water and
possibly develop a joint project that provides for economies of scale will continue.
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
l slower growth rates may push projected water use demands further out in time. In addition,
Joptions to expand our CAP water deliveries through Tucson Water will also provide a benefit
to defer mayor capital costs for the development and implementation of the more expensive
options for CAP water delivery.

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 and 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 following are programs and services provided by the
Conservation Division.
➢ Water Audits
• Assessment of water use both inside and outside the home or business and includes
residential, commercial, and neighborhood common areas
• Approximately 144 audits were completed in 2012
• Approximately 1,630 audits have been completed since the program began in 2003
• Average water savings of 20% in the first year after the audit

➢ Youth Water Conservation Education Program
As part of our water conservation education efforts, the Water Utility is in the process of
developing a youth education program for Oro Valley schools that includes 2 components
and time scales.
_22_
The first component is to design a children's water conservation activity booklet for 3rd
grade education levels which is found to be an optimum level to introduce conservation
curriculum. The booklet would be a stand alone product and available for distribution at
events and through our office. The projected completion date is summer 2013. The second
component is the development of an outreach education program in participating schools.
Instructors will present conservation education and distribute the activity booklet to reinforce
lessons learned. The anticipated start of this program is fall 2013.
➢ Incentives
The current incentive program includes irrigation system rain sensors which are sold at a
reduced rate to our customers. It also includes low -flow shower heads and low -flow sink
aerators at no cost to our customers.
• Approximately 665 rain sensors have been sold to date
• 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.
➢ Additional Programs related to Water Conservation
In addition the water conservation programs above, the Water Utility has developed its
renewable water resources to conserve our groundwater. This includes the reclaimed water
system and the delivery of a portion of our Central Arizona Project water. The use of
renewable water resources is vital for groundwater conservation and preservation to help the
Town achieve sustainability.
The Utility also has a Drought Preparedness Plan, which identifies criteria and action plans
for various stages of drought.

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. There are a total of 49 sites that are maintained by the Production Facilities
staff. 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).
Water systems are classified by the level of operator certification required by ADEQ.
Operator certifications are classified into one of four grades by facility type, size, complexity
and population served. The grade corresponds with the level of system complexity, with
Grade 1 being the most simple and Grade 4 being the most complex. More information can
be viewed regarding water quality and water systems at the ADEQ website at
www. azdeg. gov.
The two potable water systems are chlorinated systems controlled and monitored by the
Production Facilities Division. Chlorine dosage rates and residuals are monitored 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. 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 14.72 million gallons
per day (10,219 gpm) with a storage capacity of 10.7 million gallons. The groundwater
production capacity within the CSWSA is currently 2.59 million gallons per day (1,797 gpm)
with a storage capacity of 0.90 million gallons. The CAP delivery capacity into the OVWSA
system is 1.44 million gallons per day (1000 gpm).
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 a more accurate water
level database and to analyze trends. Monthly monitoring of the water levels also helps 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.
-24-

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. The SCADA system is currently undergoing a major
upgrade.
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.
-25-
Distribution Facilities Division
Utility personnel in the Distribution Facilities Division are responsible for the operation and
maintenance of 343.1 miles of potable water main, 12.6 miles of reclaimed water mains for a
combined total of 355.7 miles of water mains. There are 2,066 fire hydrants and 7,525 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 ADEQ (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 the documentation of maintenance and replacement of
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 complaints, water quality, service line breaks, hydrant
repairs, system pressure regulating valves, system air relief valves and system flushing.
Repair of water line leaks are always treated as an emergency and are repaired quickly to
minimize impacts to our customers. 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, 760 air relief valves and 878
drain valve assemblies.

in conjunction with the Production Facilities Division, provides 24-hour on -call staffing to
respond to water system problems. In addition to providing 24-hour on call service, the
Distribution staff has taken on more responsibilities by repairing more main line and service
line breaks. The Distribution staff will continue to provide a high level of professional
performance and courteous service to our customers.
-27-
SECURITY AND EMERGENCY RESPONSE PLAN
The Public Health Security Act and the 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 any situational impact on
the integrity of the water system. 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 2012, 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 2012, 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 2012, 32 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.
_28_
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
("fingerprint") the water produced. This will help identify any anomalies during a suspected
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
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
emergency.
-29-
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.
Geographic Information System (GIS)
The GIS 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. Maps produced by GIS facilitate Operations and Planning and
Engineering.
New Development
The New Development Section is responsible for facilitating development by reviewing and
approving water improvement plans for proposed new developments. In 2012, the New
Development Section reviewed and approved 10 water improvement plans for construction.
Five plans were constructed, inspected, approved as -built, and placed into service. The
completion of these New Development projects together with Capital projects added
approximately 1.55 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.
CAPITAL PROJECTS
The Engineering and Planning Division manages the design and construction of capital
projects identified in the capital improvement program. and annual operating budget. These
projects are designed to improve efficiencies to existing facilities and improve service levels.
These capital projects are described below.

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 Operating 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 related 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.

As has been done in the past, in May 2012 the Utility paid off older bonds with higher
interest rates and refinanced at lower interest rates to reduce outstanding debt and annual debt
service payments. The new debt was structured to realize the most savings 10 years out when
the need for new debt would be greater. Additionally, the Utility paid down the debt in the
PWSDIF by $3,000,000 with this refinance. The Water Utility and Finance Department will
continue to review bonds and debt service to look for opportunities to reduce debt obligations
when it is fiscally sound and there is a financial benefit. By reducing outstanding debt, it will
be easier to maintain the required 1.30 debt service coverage requirement which may result
in smaller rate increases.

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 2012, 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.
All current water rates, fees and charges are available to view on the Town website at
hgp: //www. orovalleyaz. gov/Town Government/WaterUtility/Water- Rates and Fees. htm
As recommended by the Water Utility Commission last year, the Utility has hired a
consultant, CH2M HILL, to conduct a cost of service study. CH2M HILL will incorporate
the water rates analysis in the study. The study is anticipated to be completed by the end of
June 2013.
With the changes in the state statute regarding development impact fees, CH2M HILL will
also be preparing an impact fee analysis on the Utility's two impact fees. The study must be
completed by November of 2013 in order to have the revised fees in place by August 1,
2014. The Alternative Water Resources Development Impact Fees were increased in
December 2008 and the Potable Water System Development Impact Fees were increased in
September 2007. The current 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
prepared during 2013 that contains information on the three funds that comprise the Oro
Valley Water Utility. Each fund will be individually analyzed with regard to revenue and
J revenue requirements. It is anticipated that the Water Rates Analysis Report will be
completed in June of 2013 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.
