3. UPDATE AND REVIEW OF COMPREHENSIVE PLAN FOR THE
DEVELOPMENT OF CENTRAL ARIZONA PROJECT WATER (P.
Saletta) Discussion and/or possible action regarding the planning for the
development of Central Arizona Project Water. Discussion may include
interim delivery of Oro Valley's CAP water through the Tucson Water
system, recharge and recovery, and direct treatment and delivery. Various
studies, costs, impacts to water rates and next steps regarding CAP water
delivery may also be discussed.
Mr. Saletta presented a draft presentation to the Commission which will be
presented to Town Council on March 16, 2011. Mr. Saletta pointed that Tucson
Water had a draft report indicating that the acre foot payment could be in the
vicinity of$500. The draft analysis report originally reported the payment to be
$562. This payment will be finalized in the Intergovernmental Agreement with
Tucson Water and will be brought back to the Commission and Council for
approval.

3/14/2011 MINUTES, ORO VALLEY WATER UTILITY COMMISSION
Mr. Saletta gave a quick over view:
-Water Supply Portfolio -Water Supply and Usage -Need to develop
Renewable Water Resources
-CAP Delivery Options (Focus on Short-term options)
-Inform and update Council regarding plan to develop CAP water
The reason for the presentation is to inform Council about the Utility's plan to
develop CAP water and to seek direction from Council to proceed with
discussions and negotiations with Tucson Water.
Mr. Saletta reviewed the OVWU Water Use and Supply Map and explained that
Oro Valley's goal is to be under the 5,500 AF sustainable groundwater
production level. He also explained the various options of 1,000 thru 3,000 acre-
feet per year (AF/YR) interim deliveries through Tucson Water's delivery system.
Mr. Saletta mentioned that the Projected Demand is based upon 1% to 3%
growth rate.
Mr. Saletta also explained the need for Renewable Water because of declining
water levels, meeting Assured Water Supply requirements, the need to reduce
reliance on Central Arizona Groundwater Replenishment District, and that this
project will deliver "wet" water not "paper" water credits.
Staff will also present the various Short-term CAP Delivery Options available to
Oro Valley based on Cost per AF estimates. He explained that the net adjusted
cost after considering power and CAGRD savings is approximately $387
(1,000 AF/YR), $445 (1,500 AF/YR) and $678 (3,000 AF/YR). All of the
advantages and disadvantages will be listed in the CAP Delivery Options table.
Although, there are no significant increases as a result of these projects it
will affect the Utility's ending cash balances because the 1,500 AF option will be
cash funded. The 3,000 AF/YR option will affect the ending cash balance
because of the debt service payments.
-The cost per acre-foot (AF) estimates are they based on the original cost of
$562? (Commissioner Reynolds). Mr. Saletta confirmed that the estimates
included the $562 per acre-foot cost. These costs could come down when a set
payment is agreed upon.
-Is the cost per AF being adjusted before it is presented to Council?
(Commissioner Milkey). Mr. Saletta stated that Council will receive the same
information that the Commission has to date and that the costs will not be
adjusted until finalized payment to Tucson Water has been determined and
agreed upon. That payment amount will be brought back to the Commission
and Council for approval in the IGA.

3/14/2011 MINUTES, ORO VALLEY WATER UTILITY COMMISSION
-Will you be keeping the Commission informed about the negotiations with
Tucson Water? (Commissioner Shapiro). Mr. Saletta indicated he will keep the
Commission updated. He explained that negotiations could take a while but he is
hopeful that everything could be completed by June with approval possibly in
July.
Schedule:
-7/?/11: Town Council consideration of IGA
-8/1/11: OVWU Staff commences design
-10/1/11: OVWU Staff commences construction
-1/1/12: Short-term/interim CAP delivery in operation
Commissioner Milkey requested that any significant developments or updates
between Town Council be emailed to the Commission as quickly as possible.
Mr. Saletta explained that if the Water Utility Commission has reviewed the
Tucson Water short-term CAP delivery options and recommends moving forward
with discussions and negotiations, a draft Intergovernmental Agreement will be
developed for review and future consideration by the Commission and Council.
Mr. Saletta indicated that Staff requests and recommends moving forward. Mr.
Saletta also mentioned that the results with Tucson Water's study looks good,
but we need to proceed cautiously with the IGA.
-Is there sufficient time until the IGA is finalized to get infrastructure
construction done and be ready and operational in January? (Commissioner
Reynolds).
Mr. Ruiz explained that Staff is meeting with Tucson Water to discuss what
infrastructure would be required to deliver the required volume of wheeled water
to the Town of Oro Valley. Design would not start until the IGA is approved. He
was very confident that Tucson Water would be ready and also explained that
they were currently modeling their water flows. Staff will be meeting with Tucson
Water design staff in the near future. The design work offsite connection points to
Oro Valley's water system will be done by Oro Valley. Mr. Ruiz felt that both
design projects could be completed in 3 months and take approximately 3 to 6
months to build.
Commissioner Milkey emphasized the over pumping of 2,100 AF of groundwater
per year and if we can replace 1,500 AF, we have really cut the percentage in
over pumping.
Commissioner Tustison indicated that Council must understand the
importance of 5,500 AF sustainable groundwater level and the details in the chart.
Mr. Saletta mentioned he would spend time with Council answering any
questions.

Commissioner Hoffmann also felt that Council must be allocated sufficient time
to understand what is being presented. Mr. Saletta indicated that the
presentation could take 5-7 minutes and will be followed with a question and
answer session.
Commissioner Shapiro indicated that the Countryside wells were declining
and asked how CAP wheeling would affect the Countryside area. Mr. Saletta
mentioned that over the last five years, Countryside area wells have declined .75
feet on average and are doing better than Oro Valley's aquifer. Countryside will
not receive direct CAP water delivery but will receive its water through the
recovery wells located in the Countryside Water Service Area.
There were no further questions, Mr. Saletta ended his report. No action was
required on this item.
Call to Audience: Mr. Doug McKee Oro Valley resident mentioned the problems
with the water table declines, and questioned the accuracy of the 5,500 AF
sustainable groundwater productions established several years ago. He felt there
could be new engineering data to re-verify or re-calibrate the existing 5,500 AF.
He also mentioned that the residents and Council must understand why the
3,000 AF delivery option was being delayed, what are the financial obligations or
engineering reasons. He also felt that CAP deliveries could be increased.
4. OVERVIEW OF THE CENTRAL ARIZONA PROJECT ACQUISITION,
DEVELOPMENT AND DELIVERY WATER PROJECT (P. Saletta)
Discussion and/or possible action regarding the CAP Acquisition,
Development and Delivery (ADD) Water Project. This is a project that
involves numerous stakeholders and the CAP Staff to look at new water
supplies for Arizona.
Mr. Saletta updated the Commission regarding the Acquisition, Development and
Delivery Water Project (ADD Water):
He explained that CAP staff and various other stakeholders meet to discuss the
opportunities to deliver more Colorado River water to Arizona. He indicated that
the canal has more delivery capacity than water delivered through CAP water
rights off the Colorado River. This capacity is estimated to be about 300,000 AF.
However, there is a problem getting the required capacity and having it delivered
to the numerous water providers.
There are several parties interested in the ADD water project, development
interests, Arizona Department of Water Resources, Central Arizona Groundwater
Replenishment District, Arizona Water Banking Authority, Arizona Municipal
Water Users Association, Southern Arizona Water Users Association, Northern
Arizona Municipal Users Association.

3/14/2011 MINUTES, ORO VALLEY WATER UTILITY COMMISSION
There have been discussions on how CAGRD fits into the acquisition and
allocation process, will they be competing with water providers, and how they will
meet their demands in the future. Oro Valley is also a CAGRD customer.
There are several outstanding issues:
-Planning costs, acquisition costs, delivery costs
-Availability of water on the river and whether the numerous parties pursue this
effort individually/jointly or will CAGRD do it independently. There could be a
lot of synergies if all work together.
Mr. Saletta believed it was important for Oro Valley to participate in the ADD
Water project in order to consider additional supply of Colorado River Water
for Oro Valley's future growth by year 2025.
He also emphasized that the acquisition for additional sources of water supply
could be very expensive in addition to the infrastructure, but it was very important
for Oro Valley to participate in the project.
Mr. Saletta indicated he was the representative for Oro Valley and the Southern
Arizona Water Users Association.
-What kind of sources of water are they making available? (Commissioner
Hoffmann). Mr. Saletta said they could have purchase some agricultural water
rights on the Colorado River or treat brackish groundwater depending on the
feasibility and availability in the West Phoenix area. However, the main focus is
the Colorado River water.
There were no further questions, Mr. Saletta ended his report. No action was
required on this item.
5. UPDATE ON METER REPLACEMENT PROGRAM (S.Seng) Discussion
and/or possible action regarding the activities and benefits of the Meter
Replacement Program.
Ms. Seng reported on the Meter Replacement Program:
-Overview: Purpose, Statistics, Automated Meter Reading (AMR), New meter
type, Proposed meter replacement project in Countryside service area
-Purpose: Replace all malfunctioning meters that typically under register flow as
they age. Ms. Seng gave several examples (monitor volume of water, bill for
actual water used, reduce lost and unaccounted water, water conservation).
-Statistics: Formal meter replacement began late in 2008, prior to program
implementation; the utility replaced a total of 503 meters in a 7 year period.

3/14/2011 MINUTES, ORO VALLEY WATER UTILITY COMMISSION
-Meter replaced since new program: CY 2009= 627, CY 2010= 469, CY 2011
(ytd) = 252 Total: 1,348
-Photos: 3-inch meter replacement. Ms. Seng circulated two 5/8 inch meters for
the Commission's viewing. She explained the significant difference in
size between a 3-inch meter and a 5/8 inch meter.
-Automated Meter Reading (AMR) equipment consists of transponders, receivers
and encoders. Currently 474 meters are equipped with AMR. The data is sent
from meter to receiver to laptop computer. The data is downloaded to the billing
system; AMR eliminates data entry errors by manual reading and reduces labor
costs
-AMR installations prioritized based on safety first followed by reduction in read
times
-The area where AMR's are installed include the Highlands Subdivision, Oro
Valley Market place, Mercado Del Rio Commercial site and Campo Bello
Subdivision.
New Meter Type iPERL: Circulated the new Dana Kepner meter iPERL and the
existing meters to the Commission. iPERL is very accurate and has no moving
parts with magnetic field technology and a 20 year life. In the Countryside Water
Service Area, 188 iPERL meters have been installed.
A brief discussion occurred about the cost of the new meters and whether it
required a low flow indicator. Ms. Seng indicated that the meters did not require a
low flow indicator. Ms. Seng also mentioned there was less pressure lost since
there were no moving parts with these new meters.
-Is the initial cost of the iPERL significantly greater than the others?
(Commissioner Milkey). Ms. Seng said yes, but the iPERL meter costs were
included in the last rate increase to Council so the meter rates were appropriately
increased. She explained that the meters are made in 5/8 & 3/4 inch, the 1 inch
are not available yet.
Proposed Meter Replacement in the Countryside Service Area
are 2,223 meters and is a 40 minute round trip for field staff with a manual meter
read time of 1 person for 32 hours.
Proposed project: Replace existing 5/8" meters with iPERL meters, all
commercial have been replaced with T2 & C2 meters -Install radio read
equipment on meters, All meters would be read electronically from the office
through Automated Meter Infrastructure (AMI) tower base station.

3/14/2011 MINUTES, ORO VALLEY WATER UTILITY COMMISSION
-Do the meters read in total gallons or can you also get instantaneous flows in
gallons per minute? (Commissioner Davis). Ms. Seng was not certain, but if the
project is approved she would have the vendor come in and give a presentation
for the Commission.
-Can you tell if someone has a leak from these meters? (Commissioner Shapiro).
Ms. Seng responded yes, all staff that have access to the Utility's data billing
base will have the software availability, also every customer can have read-only
access to their own account via the Internet and can see their water consumption
patterns (by the hour, day, week or monthly).
Ms. Seng outlined the advantages and disadvantages of the Proposed Meter
Replacement.
-What is the life expectancy of the iPERL versus the old meters? (Chair Powell).
Ms. Seng mentioned that the iPERL was about 20 years as opposed to the
existing 10 years.
-Public Relations: -Billing inserts -Article in Countryside Community Association
newsletter -Open house at Countryside Community Center.
Commissioner Shapiro mentioned that she would be glad to help Staff with the
open house and newsletters.
How long will water service be interrupted with the new meter replacements?
(Commissioner Milkey). Ms. Seng mentioned it could take only 10 minutes per
meter.
-When would you anticipate doing this program? (Commissioner Tustison). Ms.
Seng indicated if approved in the budget it could begin July or August.
Ms. Seng also indicated there were 2,223 meters in Countryside Service area
and there are more meters than homes.
-Do you have the separate number for the unaccounted water in Countryside?
(Commissioner Milkey). Ms. Seng indicated that for year 2010 it was 9.75% and
it was higher than Oro Valley's combined average but they are reported to the
State together.
-If someone has a leak in their meter are they being replaced with the new
i-PERL meters? (Commissioner Shapiro). Ms. Seng indicated yes, and that Oro
Valley meter replacements will also have the iPERL meters.
There were no further questions, Ms. Seng ended her presentation. No action
