WATER RESOURCES The Utility operates two water systems, the Oro Valley Water Service Area and the Countryside Water Service Area. There are three sources of supply: groundwater, Central Arizona Project water and reclaimed water. Groundwater is pumped from the wells in the aquifer below the water service areas, blended with the Central Arizona Project water and then delivered through the potable drinking water distribution system. Reclaimed water is for non-potable uses and is predominantly used for irrigation on golf courses, parks and athletic fields. The potable drinking water system is completely isolated from the reclaimed water system. TABLE 1 Total Water Produced in 2021 (Acre Feet) Groundwater CAP Water Reclaimed Water Total Water Produced 4,997 2,671 1928 9,596 The Utility uses Central Arizona Project water in the following three ways: 1) Recharge and recover water for delivery to the potable water systems in both Oro Valley and Countryside 2) Recharge for replacement credit to apply to water pumped from the Utility’s wells 3) Recharge and store water in recharge facilities for future use As of December 31, 2021, the Utility has accrued an estimated 29,500 acre feet of long-term storage credits and has a Groundwater Allowance Account balance of approximately 19,230 acre feet. CUSTOMER SERVICE At the end of 2021, the Utility had 20,966 customer connections serving a population of approximately 49,300 residents in the service area. Utility water sales revenues totaled $14.7 million for fiscal year 2020-21. 5 WATER CONSERVATION The Utility encourages water conservation by informing and educating customers. Specifically, in 2021, the following conservation efforts were accomplished: ➢ First edition of the quarterly newsletter Behind the Meter ➢ Additional publications: Water Wisdom Video Series and Virtual Welcome Guide ➢ Over 8,200 automated alerts sent with water savings of over 16.5 million gallons ➢ 45% of leaks confirmed by customers on WaterSmart were related to irrigation WATER UTILITY OPERATIONS Water Operations are a 24 hour per day, seven days per week operation. Staff performed routine maintenance on all production and distribution facilities. Utility personnel inspected new development projects and the Utility’s capital projects. In 2021, Water Operations completed the following: ➢ Commission – La Reserve Reservoir ➢ Staff cross training – internal and external employees ➢ Warranty replacement of 2 faulty water reservoir mixing units ➢ Distribution maintained 1,587 water valves, replaced 3 valves and performed 55 valve adjustments WATER QUALITY In 2021, the Utility received 2,704 analytical results for required water sampling and operational data. The water system is in compliance with the Arizona Department of Environmental Quality and the United States Environmental Protection Agency requirements. FINANCIAL HIGHLIGHTS The Utility continues to be fiscally sound. The water rate study for FY 2022/23 resulted in a recommendation to increase the base rates and commodity rates for potable water customers. These proposed changes will result in a monthly increase of $1.79 per month for a customer with a 5/8-inch meter using 7,000 gallons month. Customers with a 5/8-inch meter represent 87 percent of the total customer base and include residential, commercial and irrigation classifications with the majority being residential. The proposed changes will be presented to the Town Council in June 2022 and, if adopted, the new potable water changes would become effective in July 2022. All current water rates, fees and charges including impact fees are available to view on the Town website at https://www.orovalleyaz.gov/town/departments/water-utility/rates-and-fee 6 TOWN OF ORO VALLEY WATER UTILITY ANNUAL REPORT APRIL 2022 INTRODUCTION This report provides information to the Mayor and Council and the public on the annual work of the Water Utility Commission and updated information on the Oro Valley Water Utility (Utility). The report outlines how the divisions within the Utility work together to provide the community with reliable and safe water supplies. Through partnerships with other professional water agencies, the Utility maintains water quality standards, protects the groundwater supply, and conducts long-term planning for water resources and capital infrastructure. The report details how the Utility maintains financial health through analyzing and initiating responsible water rates and through cost recovery for new development. This report provides information and details activities for calendar year (CY) 2021 with additional financial information reported for the fiscal year (FY) ending June 30, 2021. WATER RESOURCES The primary function of the Utility is the production and efficient use of available water resources that meet or exceed water quality standards. To ensure long-term sustainability, the Utility works closely with regional water providers, state agencies and the development community in planning for future water resource requirements. Utility staff closely monitors all water resources in the Utility’s water portfolio. The water portfolio includes groundwater, Central Arizona Project (CAP) water entitlement, reclaimed water entitlement, long -term storage credits and groundwater allowance account credits. Current Water Supply includes groundwater, CAP water and reclaimed water. The Utility operates in two separate water service areas: the Oro Valley Water Service Area (OVWSA) and the Countryside Water Service Area (CSWSA). The CSWSA was acquired by the Town with the acquisition of the private water companies in 1996. This small satellite service area is located approximately two miles from the western boundary of the Town. Data from these two service areas is combined for regulatory reporting purposes. The following table provides the water production in acre feet (AF) for both service areas in 2021. TABLE 2 Total Water Production in 2021 Water Resources OVWSA CSWSA Totals Groundwater 4,544 AF 453 AF 4997 AF CAP Water 2,494 AF 176 AF 2,670 AF Reclaimed Water 1,872 AF ---- 1,872 AF Total 8910 AF 629 AF 9,539 AF 7 Total water production for 2021 was 183 acre feet less than the total water production in 2020. This decrease is due to customer response to a wetter than average summer compared to 2020. Figure 1 shows total water production in each service area from 2000 through 2021. The components of total water production include 1) groundwater production 2) CAP water utilization and 3) reclaimed water utilization. The graph depicts the decrease in overall water production for 2021 as compared to 2020 as well as the dramatic decrease in groundwater utilization since 2005. FIGURE 1 Groundwater target maximums are also illustrated on the graph shown in Figure 1. These target amounts were defined in a study entitled Groundwater Sustainability Evaluation of the Oro Valley Aquifer dated March 14, 2007. The study concluded that the annual groundwater production flow rate for wells in the OVWSA should be established at 5,480 acre feet and 880 acre feet for wells in the CSWSA. In 2021, Oro Valley pumped 936 acre feet less than the groundwater target maximum production rate for the OVWSA well s and 427 acre feet less than the target maximum production rate for the CSWSA wells. The groundwater production targets have not been exceeded since 2011. Groundwater remains the primary potable water resource for the Utility. In 2021, the Utility’s 18 groundwater production wells produced 53 percent of the Utility’s total water production. 8 Table 3 highlights the production capacity in all wells, the storage capacity in all reservoirs and the average rise or decline in static water levels for the wells in both service areas at the end of CY 2020. TABLE 3 Groundwater Production Capacity Storage Capacity (Gallons) Average Water Level +Rise/-Decline OVWSA 13.1 MGD 11 Million -0.58 Feet CSWSA 2.2 MGD 1 Million -2.51 Feet On an individual basis, groundwater level changes in 2021 for active wells varied from a rise of 4.12 feet to a decline of 7.66 feet. Details on static groundwater levels for individual wells may be found in Appendix A. Central Arizona Project (CAP) Water is the Utility’s only other potable water resource. In 2021, the Utility’s four CAP wheeling locations delivered 2 8 percent of the Utility’s total water production. The Utility delivers its entire annual CAP entitlement of 10,305 acre feet to several recharge facilities in the Tucson Active Management Area. In 2021, the Utility purchased the entire entitlement for use as follows: 1) Recharge and recover water for delivery to the potable water system 2) Recharge and replace water pumped from the Utility’s wells 3) Recharge and store water in recharge facilities for future use When Oro Valley’s CAP water is recharged and recovered for delivery, it is first delivered to Tucson Water’s Central Avra Valley Storage and Recovery Project. The recharged CAP water is then recovered and delivered (wheeled) through the Tucson Water system to various connection points on the Oro Valley system for delivery to Utility customers. The Utility has an Intergovernmental Agreement (IGA) with Tucson Water enabling the delivery of CAP water to customers through four connections to the Tucson Water system. There are three CAP water connection points in the OVWSA. One is located on Vista del Sol, north of Naranja Drive a second connection is on Calle Buena Vista, south of Calle Concordia and a third is located near Oracle and Hardy. CAP water is also delivered to the CSWSA at a connection located on Camino de Oeste, just north of Linda Vista Blvd. The Utility delivered 2,671 acre feet of CAP water in 2021 thus reducing its reliance on groundwater. CAP water deliveries are shown in Table 4. 9 TABLE 4 CAP Water Deliveries in 2020 Locations Delivery Vista Del Sol (OVWSA) 1,618 AF Calle Buena Vista (OVWSA) 395 AF Oracle & Hardy (OVWSA) 480 AF Camino De Oeste (CSWSA) 177 AF Total 2,670 AF In calendar year 2017, the Town of Oro Valley, Metro Water and the Town of Marana began collaboration on the development of a unique IGA to construct a future project known as the Northwest Recharge, Recovery and Delivery System (NWRRDS). The IGA was unanimously approved by each governing body in March of 2017. This agreement provides another means for the Town to deliver CAP water to the Utility’s service areas. The project is estimated to be completed in FY 2024 and will allow for the annual delivery of up to an additional 4,000 acre feet of recovered CAP water. The reservoirs on the Colorado River supply water to the CAP and other water projects in the lower basin states of Arizona, California and Nevada. In addition, these reservoirs provide required water deliveries to Mexico. This Colorado River water storage decline is due to the extended drought the basin has experienced for over 20 years as a result of decreased precipitation and snowpack. This has decreased flow in the river creating significant wa ter level declines in Lake Mead and Lake Powell, resulting in historically low reservoir levels. Over the last 21 years, water demands have exceeded available inflows for supply driving reservoir levels lower. Reservoir levels determine supply availability in accordance with shortage sharing guidelines established in 2007 and amended in 2019. Beginning in 2018, The Arizona Department of Water Resources (ADWR) and CAP staff collaborated with CAP water users and the Lower Colorado River Basin states to finalize the Lower Basin States Drought Contingency Plan (LBDCP). The LBDCP modifies the 2007 shortage sharing guidelines so that curtailments in CAP deliveries happen sooner and are larger. The goal of this plan is to close the gap between the over-allocation of the river’s natural replenishment capability and water deliveries, thus leaving enough water in Lake Mead to avoid drastic cuts to priority subcontract holders like Municipal and Industrial users. The LBDCP was approved by Governor Doug Ducey on January 31, 2019, and was later approved by the Federal Legislature and went into effect on January 1, 2020. The LBDCP specifies what the curtailments are to each of the Lower Basin States depending on the water surface elevation of Lake Mead on January 1st of the given year. Near term CAP water delivery curtailments to municipal water providers, such as Oro Valley, are very unlikely because Municipal users have the highest priority within the Central Arizona Project. CAP water deliveries to agricultural users, the Central Arizona Groundwater Replenishment District (CAGRD) and the Arizona Water Banking Authority (AWBA) will be curtailed 100 percent before Municipal users would be affected. If the Utility were to experience 10 curtailments to CAP water deliveries, the Utility could replace the curtailed volume with CAP water previously stored from various underground storage facilities until the storage balance is depleted. In accordance with the LBDCP, CAP curtailments on the order of 192,000 acre feet of the CAP’s 1.6 million acre feet entitlement begin when the Lake Mead water surface elevation falls below 1,090 feet in the August projections for the following January. Water surface elevations between 1,090 feet and 1,075 feet are considered a “tier 0” shortage. We are currently below water surface elevation 1,075 feet and are in a “tier 1” shortage. Fortunately, because the Oro Valley Water Utility is a municipal water service provider, the Utility is among the highest priority users of the CAP and will not see reductions in CAP water deliveries during a “tier 1” shortage. Unfortunately, the Utility can expect increased delivery costs of the Town’s CAP allocation due to the “tier 1” shortage. The State of Arizona offers a level of protection from potential CAP curtailments for priority CAP users through the creation of the Arizona Water Bank Authority. The AWBA has been storing water underground for municipal and industrial water users to guard against the impacts of potential CAP delivery curtailments. Over 600,000 acre feet of water ha ve been stored underground by the AWBA in the Tucson Active Management Area. This stored water will be made available to municipal water providers to mitigate curtailments of CAP water deliveries to municipal water users. In addition to the AWBA storing water, the CAGRD has stored water for the future to replenish groundwater. The Utility also continues to store a portion of its CAP water to increase its balance of long- term storage credits. This water will also be available to mitigate curtailments of CAP water deliveries. The above action plans combined with a diverse water resource portfolio reduces the chances of a water resource shortage in the event of CAP water delivery curtailments. In addition, reducing demands through an increased focus on the efficient use of water resources will help to preserve water supplies for future uses. Reclaimed Water is produced from wastewater effluent from the sanitary sewer system and then treated for irrigation and other non-potable uses. In 2021, the Utility’s reclaimed system produced 19 percent of the Utility’s total water production. Oro Valley owns all the effluent produced by its customers. The Utility has an IGA with Tucson Water to deliver reclaimed water to the OVWSA through their facility at Thornydale and Tangerine. From that location, the Utility independently operates the transmission and water distribution system that delivers the reclaimed water to reclaimed water customers in the OVWSA. No reclaimed water is delivered to the CSWSA. The Utility supplies reclaimed water for the irrigation of four golf courses, athletic fields at one elementary school and Naranja Park. In 2021, 1,751 acre feet of reclaimed water was delivered. This is a decrease of 209 acre feet compared to the 1,960 acre feet delivered in 11 2020. For 2021, the Utility utilized all of its estimated 1,600 acre feet of reclaimed entitlement. REGULATORY The ADWR requires the Water Utility to replace all the groundwater pumped from wells owned and operated by the Utility. To comply with this requirement, every acre foot of groundwater pumped is replaced through annual aquifer recharge uti lizing CAP water. The replacement of pumped groundwater can happen anywhere within the Tucson Active Management Area. Due to the lack of Utility-owned aquifer recharge facilities, the Utility recharges the aquifer outside of the service area to meet this requirement. Long-term storage credits can also be used to replace the groundwater pumped to maintain compliance with ADWR requirements. The Designation of Assured Water Supply (DAWS) issued by the ADWR requires compliance with the Fourth Management Plan in the Tucson Active Management Area. In 2021, the Utility was in compliance with all requirements under the DAWS and fully expects to meet all requirements in 2022. The ADWR requires the Utility to submit water system information and water usage data in an annual report. The information provided includes service area boundaries, total water use, population, gallons per capita per day, recharge, recovery and system water loss. Pursuant to the DAWS, the Utility has a right to pump a maximum of 13,384 acre feet per year. However, the 2007 study entitled Groundwater Sustainability Evaluation of the Oro Valley Aquifer determined that the Oro Valley aquifer has a sustainable groundwater production rate of approximately 6,360 acre feet per year (5,480 acre feet for the Oro Valley Service Area plus 880 acre feet for the Countryside Service Area). "Sustainable" in this 2007 study refers to the projected volume of water that can be pumped from wells each year as calculated over a 30-year period through 2037. The Utility has established a goal that the “sustainable” value be a groundwater target maximum value by which annual groundwater required beyond this threshold would trigger the utilization of additional renewable water resources. Groundwater levels are assessed annually to determine the impact on the aquifer and well production. Recently, groundwater levels have shown declines less than projected in the 2007 study. Long-Term Storage Credits are earned when water is recharged and stored underground for more than one year. In 2021, the Utility purchased 10,305 acre feet of CAP water for delivery to recharge facilities. Of that amount, approximately 2,702 acre feet were not used for direct delivery or annual recovery; therefore, increasing the long-term storage credit balance. The water stored will be saved for future use. At the end of 2021, the Utility calculated that it had approximately 29,500 acre feet in long-term storage credits. Table 5 shows the estimated water storage summary for the end of the 20 21 calendar year. The ADWR will make adjustments to the storage balance to account for recharge basin 12 evaporation and aquifer losses. The final balance will be provided by the ADWR in October of 2022. TABLE 5 Water Storage Summary Calendar Year 2021 (Acre Feet) Groundwater Storage Facility 2021 CAP Delivery to Storage Facility 2021 CAP Recovery from Storage Facility Storage Balance 12/31/21 Kai Farms 4,000 2,000 17,253 Lower Santa Cruz 2,805 2,297 8491 Pima Mine Road --- --- 2,868 Central Avra Valley 3,500 3,370 961 Effluent Storage --- --- 65 Total 10,305 7,667 29,702 Note: The 2021 CAP recovery from storage facility column (3rd column) represents the aggregate of CAP water either delivered to customers or used to replace the groundwater that was pumped. The Groundwater Allowance Account identifies the amount of groundwater that can be pumped, if desired, and still be considered exempt from the state's requirement for replenishment in the Tucson Active Management Area. In general, the balance in the account may be used for any groundwater pumped from a well that has a five -year average annual decline greater than four feet or water pumped from a well that is not permitted as a recovery well. In 2021, the Utility did not use any credits from the Groundwater Allowance Account. All the Utility’s wells are permitted as recovery wells; therefore, long -term storage credits were used to meet the replenishment requirements instead of using credits in the Groundwater Allowance Account. The balance in the Groundwater Allowance Account at the end of 2021 was 19,230 acre feet.

WATER CONSERVATION Water Conservation is a key component of the Utility’s overall water resource management efforts. The Water Conservation Program serves customers through community outreach and education. It engages the public with a variety of tools and information to emp hasize long- term support for more efficient water use. The Utility continually looks for new ways to engage and communicate important water information to our customers. Spring of 2021 marked the first edition of our new quarterly newsletter Behind the Meter. This publication is mailed as a billing insert to all customers and highlights information on our water resources, services, and programs offered. It is also available electronically on the WaterSmart customer portal and our website. Additional Publications ➢ Virtual Welcome Guide ➢ Water Wisdom Video Series 18 Community Outreach and Education Programs Participation in the WaterSmart Program continues to increase. This online program provides customers with a self-service tool to view their water use at any time. Early leak detection and high use notifications save water, reduce water waste and reduce the shock of high water bills. Although the program is available to all customers, Single Family Residential (SFR) and Irrigation accounts show the highest average registration rate at 25% over the last year. ➢ There are over 6,700 registered accounts on the WaterSmart Program ➢ Approximately 8,200 automated alerts were sent during CY 2021 with water savings of over 16.5 million gallons ➢ 45% of leaks confirmed by customers on the WaterSmart program were related to irrigation ➢ There were over 3,700 visits to the WaterSmart customer portal in CY 2021 The Water Audit Program is a free educational and technical assistance service offered to residential, HOA and commercial customers. Audits are typically conducted onsite and used to evaluate potential water savings for both indoor and outdoor water use. The water use information available through smart meters allows staff to help many of our customers over the phone. Irrigation is one of the most common leak problems reported by customers. Leaks related to irrigation may not be obvious to the customer. Confusion with irrigation timer settings and over watering are significant contributors to high water use complaints. ➢ Customers saved just under 1 million gallons participating in our Water Audit program (2020 audits) ➢ 38% of participants had pools ➢ Over 2,261 audits have been completed since 2003 Break Down of Leaks Reported to WaterSmart Irrigation Toilet Unspecified Pool Other LEAK TYPES REPORTED CY 2021 19 Youth Education Programs Oro Valley Water Utility partnered with the Environmental Education Exchange in 2013 to develop and manage our Conservation Kids Program (grades 1-3).

Staff updates system mapping installs new assets and performs e rosion repairs, asphalt paving and system flushing. These components are tracked by a database under the Utility’s preventive maintenance program. Distribution staff is also responsible for the departmental safety program. Distribution staff has significant direct customer contact and professionally responds to customers regarding water quality and pressure or flow related problems. Distribution staff is responsible for repair of main line and service line breaks. Distribution staff bluestakes underground water mains for all new and existing construction projects throughout the Town’s water service area. Arizona law requires that all underground utilities be bluestaked prior to any excavation to ensure the safety and welfare of the community by protecting underground facilities from damage. An inventory of all facility assets may be found in Appendix D. The following are the major activities and accomplishments of Distribution staff in 202 1: ➢ Responded to 171 customer inquiries and 97 after hour call outs ➢ Maintained 1,587 water valves, replaced 3 valves and performed 55 valve adjustments ➢ Maintenance performed on 120 fire hydrants and made 120 repairs to fire hydrants 21 ➢ Performed 124 inspections on 36 pressure reducing valves, and made repairs on 31 pressure reducing valves ➢ Performed 11,207 bluestakes for potable and reclaimed pipelines ➢ Repaired 6 main breaks ➢ Replaced 3 water distribution main line valves: 4”, 6” and 8” METER OPERATIONS Advanced Metering Infrastructure (AMI) is an integral part of the Oro Valley Water system. The advanced metering technology transformed how the Utility gathers water use data, how staff collaborates with customers, and improved water data manag ement practices. The AMI system has improved customer service by providing historical, on-site water usage data to the customer to explain a problem such as a water leak. This saves customers water, money and promotes continued water conservation efforts. Utility staff has increased their technical knowledge and skills to provide this improved customer service feature. Staff uses analytical and critical thinking skills to analyze and troubleshoot complex metering problems and technical issues within the AMI system. Staff uses AMI network software, Meter Data Management software, field collection and meter reading hardware, GIS software and data collection software to manage water usage data and develop solutions to solve complex problems and mitigate water use issues that impact Utility customers. AMI technology also increases operational efficiency by eliminating the need for labor intensive manual meter reading and reducing travel time. By increasing operational efficiencies, meter operations staff can focus their time and capabilities on oversight of the AMI system and related software. This includes proactively monitoring and maintaining the AMI system, providing instruction and insight for electronic equipment installations, programming, maintenance, and repairs. Meter operations staff members focus their efforts on improving operational efficiencies to perform additional water system preventive maintenance and commercial meter testing. The following are major activities and accomplishments of Meter Operations personnel in 2021: ➢ Installed over 500 meters for new developments Using Town equipment, the Utility’s distribution staff repaired 6 main line breaks and 8 service line repairs. The Utility realized an estimated savings of $230,000 by performing this work in-house rather than hiring an outside contractor to make these repairs. 22 ➢ Completed 110 warranty meter installs ➢ Repaired more than 20 angle meter stops ➢ Successfully completed the requirements to take over the AZ811-Bluestaking program ➢ 1 internal employee promoted ➢ 3 new employee training WATER QUALITY Water quality sampling and testing is essential to providing safe and reliable water. The Town’s water system is in full compliance with all state and federal regulations. The Utility is regulated by the ADEQ and provides all required water quality testing results to ADEQ. The Utility works closely with ADEQ to ensure all federal and state standards are met. The website for ADEQ is www.azdeq.gov. In 2021, the Utility received 2,704 analytical results for required water sampling and operational data for the potable water system and all ADEQ requirements were met. Each year, the Utility collects hundreds of water samples from 15 point of entry sites. Including groundwater wells, reservoirs and pumping stations. The Utility also samples from 58 sampling stations as required by ADEQ. These stations are located in neighborhoods specifically selected to represent the water quality delivered to the customers throughout the water distribution system. The Utility has an additional 101 sampling stations that can be used during emergencies or to meet future testing requirements. Every three years, water samples are taken from 50 private residences within the water service areas and tested for lead and copper. This sampling was completed in June of 2019 and met the EPA’s rules for lead and copper. The Utility provides all water quality testing results to ADEQ and works closely with that agency to ensure all federal and state standards are met. During 2021, 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 through wellhead chlorination, effective system monitoring, proficie nt sampling methods and routine maintenance. Testing includes water hardness which is a measurement of the concentration of calcium and magnesium. During 2021, the hardness levels in Oro Valley ranged from 2.1 to 14.6 grains per gallon (36 ppm to 250 ppm). The Utility’s water hardness ranges from soft to very hard with the majority of the water testing at moderately hard to hard. The water hardness varies depending on the volume of CAP water that is being blended at any given time in a specific pressure zone. Due to proposed regulatory changes and requirements, in 2021 the Utility continued preparation to phase in five proposed and pending EPA regulations related to monitoring rules: ➢ Fifth Unregulated Contaminant Monitoring Rule 2023-2025 ➢ Revised Long-Term Lead and Copper Rule October 2024 23 ➢ Perchlorate TBD ➢ Strontium TBD ➢ Chromium Total/Hexavalent Chromium TBD In 2022, the Utility will continue to phase in sampling and monitoring of new contaminants in accordance with regulatory requirements. The Utility produced a 2020 Consumer Confidence Report for each water system in May of 2020. These reports are available electronically. Notices were mailed to customers letting them know the reports could be found on the Town’s website at https://www.orovalleyaz.gov/Government/Departments/Water-Utility/Water- Quality#section-1 The 2021 Consumer Confidence Reports will be completed in June of 2022. In addition to sampling the potable water system, water quality samples are routinely taken on the reclaimed water system for chlorine levels and turbidity to assure compliance with regulatory standards. All ADEQ standards and regulations for reclaimed water were met in 2021. BACKFLOW PREVENTION Backflow prevention is an important component of water quality designed to protect the public water system. The purpose of this program is to keep the water supply safe from contaminants that could be introduced into the distribution system through backflow, back siphoning or back pressure from customer’s plumbing systems or internal processes. The Backflow Prevention Program is administered in accordance with the Town of Oro Valley Ordinance (O) 07-21, ADEQ Administrative Code section R18-4-215, and the guidelines of the University of Southern California Foundation for Cross Connection Control and Hydraulic Research. There are 1,445 backflow prevention assemblies in the program. The following are some of the major activities and accomplishments performed by the Backflow Prevention Division in 2021: ➢ Tested 236 backflow assemblies ➢ Repaired 32 in-ground and construction water backflow prevention assemblies ➢ Issued 41 permits for new and replacement backflow prevention assemblies ➢ Implemented new cross connection control program software 24 SECURITY AND EMERGENCY RESPONSE Under current federal guidelines, Water Operations personnel are considered first responders. Though primarily mandated by state rules with public health responsibilities (Arizona Administrative Code Title 18), water operators also have a public safety responsibility relevant to the water systems they operate which includes support of firefighting tasks. Any water system security situations also directly involve water operations along with the Oro Valley Police Department as a first response action. In 2020, Utility personnel, with the assistance of a security consultant were mainly focused on finalizing and submitting the Risk and Resilience Assessment Certifications for the America’s Water Infrastructure Act (AWIA) of 2018. Certifications for the Oro Valley Water System and the Countryside Water System were submitted, and confirmation received, before th e due date of 12/31/2020. Selective training was conducted in 2021 and Water Utility staff participated in an Emergency Simulation Tabletop Exercise. The training was in accordance with the guidelines from the Department of Homeland Security, Federal Emergency Management Agency, and the United States Environmental Protection Agency. The Utility continues to update the Emergency Response Plan and Business Continuity Plan on an annual basis and will continue to mitigate the elements defined in the vulnerability assessments as well as those identified through the course of business. Security features which include perimeter fencing, security walls, warning signage, motion sensors, and cameras at all active production facilities were inspected to maintain int egrity. Hydrants throughout the system are protected by security locking systems. The Utility is kept abreast of local, regional, and national security issues by the Water Information Sharing and Analysis Center (WaterISAC). WaterISAC has established secure and close contact with partners in government to access sensitive and classified security information. WaterISAC maintains two-way communication with the U.S. Department of Homeland Security, especially its National Cybersecurity and Communications Integration Center, the FBI, the U.S. Environmental Protection Agency, state intelligence fusion centers, and other federal and state agencies. The Utility is also a member of the Arizona Water/Wastewater Agency Response Network (AZWARN). Members of AZWARN agree to provide aid to other member utilities in the event of an emergency. 25 FINANCIAL HIGHLIGHTS The Utility is financially sound and continues to manage its revenues, control expenses, and reduce debt. The Water Utility’s outstanding revenue bonds have a rating of “AA+” from Standard and Poor’s and “AA+” from Fitch Ratings. Ratings criteria include stable economic base, sufficient water supply for current and long-term needs, a manageable capital improvement plan, timely rate increases, maintaining adequate debt service coverage and cash reserve balances. Revenues and Expenses 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 Utility has two funds: ➢ The Operating Fund is the primary fund for the Utility. Costs for the administration, operations, existing system improvements and debt service are managed in this fund. The sources of revenue are water sales, service-related charges and Groundwater Preservation Fees (GPF). The GPF funds are dedicated to pay for debt or capital costs related to renewable water resources, renewable water supplies and costs to wheel CAP water to the Town. ➢ The Water Resource and System Development Impact Fee Fund (WRSDIF) provides funding for expansion related projects for new growth, development of renewable sources of water supply and infrastructure required for delivery of those resources. The source of revenue for this fund is impact fees collected at the time water meters are purchased. 26 Table 6 below illustrates actual to budgeted revenues for Fiscal Year 2020/21 for the Operating Fund and Water Resource and System Development Impact Fee Fund: TABLE 6 * Note: Interest Income for FY 2020/21 is a negative $1,211 due to the recording of unrecognized losses per the information provided by the Town’s finance department Revenues from water sales exceeded budget by $1.6 million due to above average water usage directly related to the hot and dry weather conditions at the time. Impact fees exceeded budget by $2.2 million primarily due to higher than anticipated residential meter sales. 27 Table 7 below illustrates actual expenses for the Operating Fund and Water Resource and System Development Impact Fee Fund compared to budgeted expenses (excluding depreciation and amortization) for FY 2020/21: TABLE 7 Capital outlay was below budget due to unexpected delays with the Northwest Recharge, Recovery, and Delivery System (NWRRDS) project. Outstanding Debt Table 8 is a summary of the outstanding debt (principal only) and the annual debt service payments (principal and interest) for all funds within the Utility: TABLE 8 28 Water Rates The functions and duties of the commission include annually reviewing and developing recommendations for water revenue requirements, water rates and fee structures. The commission evaluates staff recommendations based on an annual water rates analysis to ensure the recommendations meet Town policies and bond covenants. The Utility bases its financial analysis on the American Water Works Association Cash Needs Approach. The water rate study for FY 2022/23 resulted in a recommendation to increase the base rates and commodity rates for potable water customers. These proposed changes will result in a monthly increase of $1.79 per month for a customer with a 5/8-inch meter using 7,000 gallons. Customers with a 5/8-inch meter represent 87 percent of the total customer base and include residential, commercial and irrigation classifications with the majority being residential. The proposed changes will be presented to the Town Council in June 2022 and, if adopted, the new potable water changes would become effective in July 2022. All current water rates, fees and charges including impact fees are available to view on the Town website at https://www.orovalleyaz.gov/town/departments/water-utility/rates-and-fee TOWN OF ORO VALLEY WATER UTILITY 2022 ANNUAL REPORT APPENDIX A STATIC GROUNDWATER LEVELS STATIC GROUNDWATER LEVELS The following table lists all production wells, the amount of groundwater pumped and the change in depth to groundwater between January of 20 20 and 2021 for both the Countryside and Oro Valley Main Water Service areas.

One acre foot is equal to 325,851 US gallons. Arizona Water/Wastewater Agency Response Network – AzWARN is a statewide mutual assistance program between water and wastewater utilities. This volunteer-based network allows utilities to help one another in times of emergency when the resources of a utility are overwhelmed. The foundation of the network is a signed mutual aid agreement between all participating utilities. Aquifer – An underground layer of water-bearing permeable rock or unconsolidated materials (gravel, sand, or silt) from which groundwater can be extracted using a water well. Central Arizona Groundwater Replenishment District (CAGRD) – It was created in 1993 to replenish (or recharge) the amount of groundwater pumped or delivered to its members which exceeds their pumping limitations using any water source available except groundwater. Central Avra Valley Storage and Recovery Project – An approved Underground Storage Facility operated by Tucson Water located in the Tucson Active Management Area located approximately one mile west of Sandario Road and just south of Mile Wide Road, in the Avra Valley, Pima County, Arizona. Colorado River Basin – The drainage basin of the Colorado River is located in the southwestern United States and northwest Mexico. The 1,450 mile river drains an expansive, arid watershed that encompasses parts of six U.S. (Wyoming, Colorado, Utah, New Mexico, Arizona and California) and two Mexican states (Sonora and Baja). Rising in the central Rocky Mountains in the U.S., the river flows generally southwest across the Colorado Plateau and through the Grand Canyon before reaching Lake Mead on the Arizona–Nevada line, where it turns south toward the international border at Yuma, Arizona. After entering Mexico, the Colorado approaches the large Colorado River Delta where it naturally empties into the Gulf of California. Effluent – Generally refers to wastewater that is treated and discharged to a natural water course. Oro Valley Water Utility’s effluent is treated at facilities owned and operated by Pima County. This treated wastewater effluent is the source of Oro Valley’s reclaimed water. Five Year Capital Improvement Plan – A long-term plan for development of water related projects to develop and deliver water supply to our community. It includes existing system improvements and expansion related projects to meet future demands. Groundwater – The water located in an aquifer beneath earth's surface in soil pore spaces and in the fractures of rock formations. The depth at which soil pore spaces or fractures and voids in rock become completely saturated with water is called the water table. E-2 Groundwater Extinguishment Credits – Credits that are generated when a grandfathered groundwater right is extinguished or retired and never used again. The credits are issued as a certificate from the Arizona Department of Water Resources. Ownership of the credits can be transferred from the owner to another entity within the same Active Management Area. Kai Farms – An approved Groundwater Savings Facility located at a farm near Redrock, Arizona that uses CAP water for irrigation. Lake Powell – A water storage reservoir on the Colorado River near Page, Arizona with a capacity of 24.3 million acre feet. Glen Canyon Dam forms the lake and provides hydro-electric power.
