EXECUTIVE SUMMARY
This section summarizes the activities of the Water Utility Commission, the Utility’s
operations, capital projects, water resource portfolio and financial management.
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 2022 (Acre Feet)
Groundwater CAP Water Reclaimed

Total Water
Produced
4,826 2,612 1,741 9,179
The Utility uses Central Arizona Project water in the following three ways:
1) Aquifer recharge and recovery for water delivery to the potable water systems in
both Oro Valley and Countryside.
2) Aquifer recharge for replacement credit for water pumped from the Utility’s wells.
3) Aquifer recharge in nearby recharge facilities for future use.
As of December 31, 2022, the Utility has accrued an estimated 31,686 acre-feet of long-term
storage credits and has a Groundwater Allowance Account balance of approximately 19,500
acre feet.
CUSTOMER SERVICE
At the end of 2022, the Utility had 21,114 customer connections serving a population of
approximately 49,000 residents in the service area. Utility water sales revenues totaled $14.4
million for fiscal year 2021-22.
5
WATER CONSERVATION
The Utility encourages water conservation by informing and educating customers.
Specifically, in 2022, the following conservation efforts were accomplished:
➢ First anniversary of the quarterly newsletter Behind the Meter.
➢ Survey distributed to over 13,000 customers for newsletter feedback.
➢ Over 8,500 automated alerts sent with water savings of over 11 million gallons.
➢ 43% 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. In 2022, Water Operations
completed the following:
➢ Security upgrades at two main facilities which included badge access, automa tic gate
actuators and security cameras.
➢ Staff cross training – internal and external employees.
➢ Relocated operations staff to single facility.
➢ Began SCADA software upgrade to Ignition in partnership with ITD.
➢ Partnership with Water Engineering on efficient and timely plan review.
WATER QUALITY
In 2022, the Utility received 4,732 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 2023/24 resulted in a
recommendation to increase the base rates and commodity rates for potable water
customers as well as a commodity rate increase for reclaimed water. These proposed changes
will result in a potable water monthly increase of $2.11 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. Additionally, the proposed changes will result in reclaimed
water commodity rate increase of 10 cents per 1,000 gallons. The proposed changes will be
presented to the Town Council in June 2023 and, if adopted, the new potable water changes
would become effective in July 2023.
All current water rates, fees and charges including impact fees are available to view on the
Town website at https://www.orovalleyaz.gov/government/departments/water-utility

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 of activities for calendar year (CY) 2022 with
additional financial information reported for the fiscal year (FY) ending June 30, 2022.
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 2022.

Figure 1 shows total water production in each service area from 2000 through 2022. 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 2022 as compared to 2021 as well as the dramatic decrease in groundwater
utilization since 2005.

FIGURE 1
Groundwater remains the primary potable water resource for the Utility. In 2022, the
Utility’s 18 groundwater production wells produced 53 percent of the Utility’s total water
production.
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 2022.

On an individual basis, groundwater level changes in 2022 for active wells varied from a rise
of 3.02 feet to a decline of 6.36 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
2022, 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 2022, the Utility
purchased the entire entitlement for use as follows:
1) Aquifer recharge and recovery for water delivery to the potable water systems in
both Oro Valley and Countryside.
2) Aquifer recharge for replacement credit for water pumped from the Utility’s wells.
3) Aquifer recharge in recharge nearby 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
2,612 acre-feet of CAP water in 2022 thus reducing its reliance on groundwater. CAP water
deliveries are shown in Table 4.

Total 2,612 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 2027 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 23 years as a result of decreased
precipitation and snowpack. This has decreased flow in the river creating significant water
level declines in Lake Mead and Lake Powell, resulting in historically low reservoir levels.
Over the last 23 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.
In 2022 the Bureau of Reclamation (BOR) determined that beginning in January of 2023, the
BOR would declared a Tier 2a water shortage for many Colorado River Water users including
Arizona. A Tier 2a water shortage reduces Arizona’s Colorado River allocation by 21%, but has
no effect on Oro Valley’s CAP allocation.
The BOR has requested that all Colorado River water users create a new plan to leave even
more water in the river. Six of the seven Colorado River Basin states submitted a consensus
framework plan for Colorado River water cuts that met the goals set forth by the BOR.
Unfortunately, the plan failed to gain the support of California, seen as critical to making
meaningful cutbacks since California has the largest apportionment of the river. California
released its own plan which minimizes their obligation to leave water in the river while vastly
increasing what Arizona must cut. At the time of this report’s creation, it is unclear how the
BOR will view any plan to save the river that doesn’t have the support of all the states.
The BOR needs to take decisive action. All Colorado River water users will need to commit to
reductions. The sooner the river’s demand is reduced to a sustainable level the sooner the
river will be protected, benefiting everyone. For 2023, Oro Valley will not see any reduction in
Colorado River Water deliveries, but we can expect a reduction in deliveries in future years.
Fortunately, Southern Arizona water professionals have been planning for these challenging
times for over 2 decades.
10
Figure 2 shows the relationship between the CAP priority order, Lake Mead water surface
elevation and the LBDCP. The area highlighted in yellow represents the current Tier 2a water
shortage.
FIGURE 2
The State of Arizona offers a level of protection from CAP curtailments for priority CAP users
through the creation of the Arizona Water Banking Authority. The AWBA has been storing
water underground for municipal and industrial water users for decades to guard against the
impacts of 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 is also 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 when CAP water delivery curtailments occur. 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 2022, the Utility’s reclaimed system
produced 19 percent of the Utility’s total water production.
11
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 2022, 1,741 acre feet of reclaimed water was
delivered.
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 utilizing 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.
Figure 3 graphically shows how the Utility utilized water resources in 2022 as described in
this WATER RESOURCES section.
FIGURE 3
12
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 20 22, the
Utility was in compliance with all requirements under the DAWS and fully expects to meet all
requirements in 2023. 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 w ells 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.
Long-Term Storage Credits are earned when water is recharged and stored underground for
more than one year. In 2022, the Utility purchased 10,305 acre feet of CAP water for delivery
to recharge facilities. Of that amount, approximately 2,867 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 2022, the Utility calculated that it had
approximately 31,686 acre feet in long-term storage credits.
Table 5 shows the estimated water storage summary for the end of the 20 22 calendar year.
The ADWR will adjust the storage balance to account for recharge basin evaporation and
aquifer losses. The final balance will be provided by the ADWR in October of 2023.

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 2022, 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 2022 was 19,230 acre feet.
ENGINEERING AND PLANNING
The Engineering and Planning Division is responsible for planning and managing the design,
construction and inspection of new water infrastructure for the Town of Oro Valley as well as
providing engineering support to the Water Operations group.
Engineering and Planning is also responsible for managing and maintaining a Geographic
Information System (GIS) database on all existing and new water system infrastructure. Maps
produced by GIS staff facilitate Utility operations, planning and engineering. Additionally,
Engineering has spearheaded the design and parameters for the Water Utility’s asset
management system (Cartegraph) and documenting the lifecycle of our water assets.

CUSTOMER SERVICE
Customer Service is an integral element of the Utility, providing a full range of support to its
customers. The Utility’s 21,114 metered connections serve a combined population of
approximately 49,000 for both water service areas. Customer Service responsibilities include
preparing the monthly billing, processing cash receipts, preparing daily deposits and
processing new meter applications. Staff also manages new and closed accounts as customers
move in and out of the water service areas.
Customer Service staff produced over 229,828 bills in FY 2021/22 generating $14,406,541 in
water sales revenue. This revenue does not include sales taxes, groundwater preservation
fees or service fees. Water sales revenue by user classification is illustrated in Figure 2.
FIGURE 2
The Utility has an IGA with Pima County Regional Wastewater Reclamation Department to
provide their monthly sewer billing. In addition, the Utility provides monthly and quarterly
billing for the Town’s Stormwater Utility. In FY 2021/22, the Utility processed a total of
$30,053,902 in payments for the Utility and the other two organizations as follows:
➢ Oro Valley Water Utility $ 18,588,219
➢ Pima County Wastewater Reclamation $ 9,976,807
➢ Town of Oro Valley Stormwater Utility $ 1,488,876
19
It is important to note that the total payments handled by the Oro Valley Water Utility are in
excess of the water sales billed because the payments processed include sales taxes,
groundwater preservation fees, security deposits and other service fees char ged by the
Utility.
Of the above payments processed, payments made by credit card or electronically totaled
$29.7 million or 99 percent. These payment methods create efficiencies for customers and
customer service staff. Payments are posted to customer accounts in a timely and efficient
manner. In addition, this reduces data entry errors and increases time available for staff to
perform other job functions.
In August 2022, the Water Utility implemented a new Customer Information System (CIS) that
replaced the Utility’s legacy software. This cloud-based platform provides customers and
staff with modern functions and features. In addition to CIS, this software includes a mobile
application for field staff and a customer portal. The customer portal allows customers to
manage their account, review consumption information, make payments with several
payment options, and a variety of other self-service features.
WaterSmart is a customer portal that provides customers the ability to monitor their own
water use on an hourly, daily, weekly or monthly basis. They can also set their individual
water use thresholds that will enable the technology to send them high water use alerts.
Customer Service staff use the Utility’s customer kiosk to assist customer s with registering in
WaterSmart and to teach them how to establish water use thresholds.
The major accomplishments by Customer Service staff in 2022 include the following:
➢ Produced over 292,838 water bills.
➢ Registered accounts on new customer portal was 5,700.
➢ Processed 148 new meter installation applications.
Utility statistics for 2022 may be found in Appendix C.
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 2022 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
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 34% over the last
year.
➢ There are over 7,200 registered accounts on the WaterSmart Program
➢ Approximately 8,500 automated alerts were sent during CY 2022 with water savings of
over 11 million gallons.
➢ 43% of leaks confirmed by customers on the WaterSmart program were related to
irrigation.
➢ There were over 3,900 visits to the WaterSmart customer portal in CY 2022.
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 over 500,000
gallons participating in our Water Audit
program (2021 audits).
➢ 35% of participants had pools.
➢ Over 2,299 audits have been completed
since 2003.
21
Break Down of Leaks Reported to WaterSmart
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). In 2022, we added
Discover Our Water Program to serve grades 4-5. For the current school year to date we have
reached over 1,100 students within Oro Valley and adjacent service areas.
Future Focus Areas
The Utility continually looks for ways to expand opportunities for public education
and advocacy regarding water conservation.
➢ Increase customer participation in the WaterSmart Program across all meter classes
through targeted outreach efforts.
➢ Improve our understanding of key water use patterns by leveraging the data from our
Automated Metering Infrastructure.
➢ Develop water use benchmarks that are useful and practical to Utility customers as
determined by evaluation models.

Meter Operations
Advanced Metering Infrastructure (AMI) is an integral part of the Oro Valley Water s ystem.
The advanced metering technology transformed how the Utility gathers water use data, how
staff collaborates with customers, and improved water data management 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 custom er 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.
Using Town equipment, the
Utility’s Water Distribution staff
assisted the Parks and Recreation
Department in constructing new
water mains at the Steam Pump
Ranch. This saved the Town
approximately $250,000.
25
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 oversigh t 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 f ocus their efforts
on improving operational efficiencies to perform additional water system preventive
maintenance and commercial meter testing.
Meter 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.

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 Arizona Department of Environmental Quality (ADEQ) and provides all
required water quality testing results to the ADEQ. The Utility works closely with the ADEQ to
ensure all federal and state standards are met. The website for the ADEQ is www.azdeq.gov.
In 2022, the Utility received 4,732 analytical results for required water sampling and
operational data for the potable water system and met requirements of the US
Environmental Protection Agency’s (EPA), Safe Drinking Water Act (SDWA). 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 the 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 2022 and met the EPA’s SDWA rules for lead
and copper. The Utility provides all water quality testing results to the ADEQ and works
closely with that agency to ensure all federal and state standards are met.
During 2022, the Utility collected 696 compliance samples for analysis of Total Coliform and
E.coli bacteria, all samples were negative for these contaminates. This is a direct result of a
successful disinfection program through wellhead chlorination, effective system monitoring,
proficient sampling methods and routine maintenance.
Testing includes water hardness which is a measurement of the concentration of calcium and
magnesium. During 2022, the hardness levels in Oro Valley ranged from 2.2 to 18.7 grains per
gallon (38 ppm to 320 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 hardn ess 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 2022 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
➢ Perchlorate TBD
➢ Strontium TBD
➢ Chromium Total/Hexavalent Chromium TBD
In 2023, the Utility will continue to phase in sampling and monitoring of new contaminants in
accordance with SDWA regulatory requirements.
28
The Utility produced a 2021 Consumer Confidence Report for each water system in April of
2022. 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 2022 Consumer Confidence Reports will be completed and available to
consumers by June of 2023.
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 the ADEQ standards and regulations for reclaimed water were met
in 2022.
In 2023 the Water Quality section of the Utility will begin initial implementation of SAMS
Water. SAMS Water is a scheduling monitoring and analysis software tool that helps water
systems comply with federal and state drinking water regulations. SAMS Water is an
additional module added to the Cross Connection Module we are currently using.
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 p rocesses.
The Backflow Prevention Program is administered in accordance with the Town of Oro Valley
Ordinance (O) 07-21, the ADEQ Arizona Administrative Code (A.A.C.) section R18-4-215, and
the guidelines of the University of Southern California Foundati on for Cross Connection
Control and Hydraulic Research.
There are 1,491 backflow prevention assemblies in the program. The following are major
activities and accomplishments of Water Quality personnel in 2022:
➢ Tested 259 backflow assemblies.
➢ Repaired 56 in-ground and construction water backflow prevention assemblies.
➢ Issued 42 permits for new and replacement backflow prevention assemblies.
➢ Implemented new cross connection control program software.

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 secu rity 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 the 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, moti on
sensors, and cameras at all active production facilities were inspected to maintain integrity.
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.

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.

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 2023/24 resulted in a recommendation to increase the base rates
and commodity rates for potable water customers as well as a commodity rate increase for
reclaimed water. These proposed changes will result in a potable water monthly increase of
$2.11 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.
Additionally, the proposed changes will result in reclaimed water commodity rate increase of
10 cents per 1,000 gallons. The proposed changes will be presented to the Town Council in
June 2023 and, if adopted, the new potable water changes would become effective in July
2023.

GLOSSARY
Acre Foot – The volume of water necessary to cover an area of one acre to the depth of one
foot, 43,560 cubic feet. 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.
Lake Mead – The largest water storage reservoir in the United States with a capacity of 25.9
million acre feet. It is located on the Colorado River about 24 miles southeast of Las Vegas,
Nevada. Hoover Dam forms the lake and provides hydro-electric power.
Long-Term Groundwater Storage Credit – A credit for storing CAP water or wastewater effluent
that is accrued when this water is delivered to and recharged into an approved underground
water storage facility. Once the water is recharged and stored and a deduction is taken for losses
to the aquifer, it becomes a credit that can be used in the future either by direct delivery or used
as credits to replace groundwater pumped from recovery wells.
Lower Santa Cruz Replenishment Project – An approved Underground Storage Facility operated
by the Central Arizona Project located in the Tucson Active Management Area near Marana,
Arizona.
Northwest Recharge Recovery and Delivery System – Partnership project between The Town of
Oro Valley, Metro Water and The Town of Marana to plan, design, construct and operate a
recovery and delivery system to facilitate the delivery of recovered CAP water from the Lower
Santa Cruz Recharge Project and the Avra Valley Recharge Project to each partner’s respective
service area.
Pima Mine Road Recharge Project – An approved Underground Storage Facility operated by the
Central Arizona Project located in the Tucson Active Management Area near Sahuarita, Arizona.
Recharge – The replenishment of an aquifer's groundwater. An aquifer recharges water that
percolates into the ground. Recharge takes advantage of water supplies available now and stores
them for future use. Recharge also allows the slow introduction of new water supplies into our
drinking water system by blending the new source with existing groundwater.
Tucson Active Management Area – One of five Active Management Areas in Arizona established
under the 1980 Groundwater Code to manage groundwater usage through the Assured Water
Supply Program.
Turbidity – Turbidity is the cloudiness or haziness of a fluid caused by large numbers of individual
particles that are generally invisible to the naked eye similar to smoke in air.
Zones – A “zone”, or “pressure zone” is defined as the area bounded by both a lower and upper
elevation. Water service areas with elevation changes establish pressure zones to ensure that all
customer’s water pressure is within a prescribed pressure range regardless of the customers’
service elevation. E-3

Water Utility Commission Meeting
March 13, 2023
Oro Valley Water Utility
Update & Discussion on the Partnered &
Independent Northwest Recharge, Recovery &
Delivery System
NWRRDS Partnered Project Update
The foundation of the NWRRDS Project
April 2017: The governing bodies of Metro Water, the Town of Marana and the Town of
Oro Valley unanimously approved the NWRRDS IGA, a 50-year IGA.
Capacity Entitlement: Oro Valley & Metro Water: 4,000 AFY Marana:2,400 AFY
The partnered project design is complete and consists of:
Construction & Equipping of 3 recovery wells, 7-miles of transmission pipeline and a 1-million-gallon
reservoir. Cost shared by all 3 partners based on allocation capacity. (Except for well construction
and equipping. This cost is only shared between Oro Valley & Metro Water.)
NWRRDS Partnered Project Update
Invitation for bids was published March of 2022
Thirty-seven entities requested bid documents (twenty-two were general contractors).
3 bids received, 2 were deemed responsive.
Granite construction was the apparent lowest and responsive bidder.
Bid was approximately 20% over the latest Engineer’s estimate and 30% over recent
budget projections.
Determination
For large construction projects there is a shortage of labor, material availability, lack of
supplier guaranteed pricing, competition for labor and material due to recent passage
of infrastructure law and global conflict all contribute to the escalation of bids.
Moving forward
Partners had decided not to award the contract. The Partners are evaluating the
bidding environment on an annual basis to determine the appropriate time to move
forward with a new bid solicitation
Partners are repackaging the bid documents and plan to resolicit the project mid 2023.
NWRRDS Independent Project Update
Moving forward with components of the NWRRDS Independent Project.
Those NWRRDS Independent construction elements that are not dependent on the
Partnered NWRRDS to support growth, provide system reliability and facilitate the
transmission of CAP water throughout the existing water system are moving forward.
Approximately 3-years of work to complete those NWRRDS Independent projects that
are not dependent on the Partnered NWRRDS to be beneficial to the existing system.
Not expecting gross overinflated construction costs on NWRRDS Independent
projects due to their smaller scale, and the relatively simple construction methods
compared to the Partnered NWRRDS project.
