TOWN OF ORO VALLEY
WATER UTILITY COMMISSION
WATER RATES ANALYSIS REPORT
OCTOBER 7, 2009
The functions and duties of the Oro Valley Water Utility Commission include reviewing and
developing recommendations for water revenue requirements, water rates and fee structures.
The Commission annually evaluates staff recommendations based on a rates analysis to
j assure the recommendations meet Town policies and bond covenants.
J The Utility has based its financial analysis on the American Water Works Association
(AWWA) Cash Needs Approach. The AWWA is the largest national organization that
develops water and wastewater policies, specifications and rate setting guidelines accepted
l by both government -owned and private water and wastewater utilities worldwide.
_J This Water Rates Analysis Report contains detailed information on the three funds that
comprise the Oro Valley Water Utility:
• Enterprise Fund
• Alternative Water Resources Development Impact Fee Fund
1 • Potable Water System Development Impact Fee Fund
Each fund is individually analyzed with regard to revenue and revenue requirements.
There were significant changes in assumptions used to prepare this report than what has been
used in the past. The changes include water use trends, vacant homes and/or disconnected
meters, growth trends and debt service coverage requirements. All of these will be addressed
individually within this report.
] The Water Utility Commission has made a recommendation for a Preferred Financial
Scenario. The Preferred Financial Scenario generates the revenue needed to maintain an
adequate cash balance of $2.5 million for the Enterprise Fund over the projected five year
period. Additionally, the Preferred Financial Scenario reduces the amount of future
financing by using available cash for capital projects. Coupled with the reduction in
financing, modest rate increases annually allows the Utility to avoid rate shock in future
years.
The Preferred Financial Scenario also builds the cash balance of the Alternative Water
Resources Development Impact Fee Fund over the five year period while we continue to pay
off our current debt on the Reclaimed Water Delivery System. Building this cash balance
will be important as the Town moves forward with the treatment and delivery of Central
-1-
Arizona Project (CAP) water. More information on the Preferred Financial Scenario may be
found on page 17. �-
The Preferred Financial Scenario includes five year projections for each fund. This allows
the Utility to evaluate the impact of future costs and the revenue sources that will be required
to meet those costs. Based on the data contained within the Preferred Financial Scenario, the
Water Utility Commission has made recommendations on water rates and fees that the Utility
could assess in FY 2009-10. Those recommendations are as follows:
• Increase the base rates for both the potable and reclaimed water rates by 2.0%.
• Increase the commodity rates for the potable water rates as follows:
o Tier 1 increase of 1.0%
o Tier 2 increase of 1.5%
o Tier 3 increase of 2.0%
o Tier 4 increase of 2.5%
• Increase the commodity rate for the reclaimed rates by 1.0%.
• The construction rate for potable water will increase from $6.25 to $6.38 per 1,000
gallons.
• The construction rate for reclaimed water will increase by 1.0% and will remain equal
to the reclaimed commodity rate.
• The water use contained within specific tiers will remain the same.
• Increase the Groundwater Preservation Fee by $0.20, from $0.55 to $0.75 per 1,000
gallons for potable water use.
• Increase the Groundwater Preservation Fee by $0.10, from $0.30 to $0.40 per 1,000
gallons for reclaimed water use.
• Increase the existing new service establishment fees to recover labor and material
costs.
• Increase the existing reconnection fees to recover labor and material costs.
• Increase the existing backflow permit fees to recover labor and material costs.
• Increase the existing refundable security deposits to minimize bad debt write off.
• Increase the existing meter installation fees to recover labor and material costs.
The Water Rates Analysis Report also includes an Alternate Financial Scenario for the
Council's consideration. The Alternate Financial Scenario does not propose any increase in
the base rates or the commodity rates for FY 2009-10 but does include an increase in the
Groundwater Preservation Fee of $0.20 for potable water use and $0.10 for reclaimed water
use. The Alternate Financial Scenario incorporates most of the same basic assumptions as the
Preferred Financial Scenario. More information on the Alternate Financial Scenario may be
found on page 21 of this report.
The Commission presents this Water Rates Analysis Report for the review and consideration
of the Mayor and Council. The Commission and Water Utility Staff are available to discuss
this report in greater detail at the Council's request. Utility Staff are planning to request
Council's approval of a Notice of Intent on October 7, 2009 which will set a Public Hearing
date for November 18, 2009 and make the report available for public review. The Notice of
Intent initiates the process and does not approve any changes or increases in water rates.
-2-
Approval of any rate increases would be considered by Town Council at the Public Hearing
on November 18, 2009.
The Oro Valley Water Utility Commission is proud to serve the Town of Oro Valley, its
1 citizens and the customers of its water utility. The Commission extends their appreciation to
the Mayor and Council for their consideration and guidance and looks forward to their
continued direction.

WATER RATES ANALYSIS REPORT
OCTOBER 7, 2009
I Q1I .Tlllisle] _I ffle1
The Oro Valley Water Utility was established in 1996 as a self-supporting enterprise of the
Town. The Utility is comprised of three separate funds that have been established for
specific purposes. The Funds are as follows:
• Enterprise Fund
• Alternative Water Resources Development Impact Fee Fund
• Potable Water System Development Impact Fee Fund
The Enterprise Fund is the operating fund for the Utility. The expenditures managed from
this fund include personnel, operations and maintenance for both potable and reclaimed
water systems, capital costs for existing potable water system improvements and related debt
service. Revenue for this fund includes water sales, service fees and miscellaneous charges
and interest income. The Utility does not receive any funds from the Town General Fund.
The Alternative Water Resources Development Impact Fee Fund was established in 1996 to
manage capital expenditures related to alternative water resources including reclaimed water
and Central Arizona Project (CAP) water. Expenditures include acquisition of water rights
required for growth and capital costs, including debt service, to deliver reclaimed water and
CAP water to the Town. Revenue for this fund is received from impact fees collected at the
time water meters are purchased and from interest income. Additionally, the Groundwater
Preservation Fees, which are collected through the Enterprise Fund, are transferred to the
Alternative Water Resources Development Impact Fee Fund to pay for capital costs and debt
service.
The Potable Water System Development Impact Fee Fund was established in 1996 to
manage capital expenditures related to expansion or growth -related potable water capital
projects and related debt service. These projects include wells, pump stations, reservoirs and
mains for the potable water system. Revenue for this fund is received from impact fees
collected at the time water meters are purchased and from interest income.
The revenue and expenditures of all three funds are combined primarily to determine if the
Utility meets the debt service coverage requirement established in the Mayor and Council
Water Policies and the 2003 Bond Covenants. Otherwise, each fund is independent with
regard to revenue and expenses. The revenue from the individual funds may not be
consolidated nor used for any purpose other than for which they were originally established.

There were changes in key assumptions used to prepare this report other than what had been
used in the past. The changes include water use trends, vacant homes and/or disconnected
meters, growth trends and debt service coverage requirements. All of these will be addressed
individually within this report as they have a significant impact on the analysis and projected
water rate increases.
1`LI VYDI:i1MAI Y;7x►f�y
The Utility has experienced an overall reduction in water use, both potable and reclaimed,
over the last two years. The chart below illustrates a 4.7% reduction in water use from
calendar year 2007 to 2008. This data is based on actual water use for both years. The 2009
reduction in water use is projected using actual water use for January through August of 2009
and estimating the same water use as in 2008 for the months of September through
December. The reduction in water use for 2009 is estimated at 2.1% less than in 2008. The
combined 2 year reduction in water use is estimated to be 6.9%. The reduction in water use
is a result of a combination of occurrences including conservation, reduction in growth,
vacant homes and/or disconnected meters. The average single family residential customer
-5-
with a 5/8 x 3/4-inch water meter reduced their monthly water use to 8,093 gallons, down
from 9,000 gallons in 2008. For the analysis in this report, the average monthly water use for
a single family residential customer with a 5/8 x 3/4 inch water meter will be calculated at
8,000 gallons per month. Monthly water use was also reduced in all other customer
classifications. Revenue projections for this analysis included this reduction in water use. r

VACANT HOMES AND/OR DISCONNECTED METERS
2009
To ascertain why water use has declined, the Utility's customer base was analyzed. The
analysis revealed that 238 meters were disconnected or had the water service turned off and
locked as of August 20, 2009. The following is the classification of those meters:
➢ Residential
160
➢ Commercial
9
➢ Irrigation
59
➢ Construction
10
Each account was categorized by user classification and meter size and then analyzed to
project if and when the water service would be restored. It was assumed that 20% of all
residential meters would be re -activated annually beginning in FY 2010-11. After review, it
was determined that all construction meters were homes that were under construction when
the water service was disconnected thus it was assumed that 20% of these meters would also
be re -activated annually. Analysis of the commercial accounts revealed that it was highly
unlikely that any of these meters would be re -activated. Likewise, the majority of irrigation
meters were for common areas which are not likely to be re -activated in the near future.
These meters are not being billed; therefore, there has been a negative impact on water sales
revenue. This impact was factored into the 5 year projections as a reduction in water sales

and Groundwater Preservation Fees (GPF) revenue. As the meters are projected to be re-
activated, the reduction in revenue is minimized proportionate to the number of meters, meter
J size and projected water rates on an annual basis. The following table shows the projected

GROWTH TRENDS
The Utility's growth rates have decreased significantly over the past several years. The
growth projections used for this report were provided by the Town's Finance Director and
are consistent with the Town's overall financial planning. The chart below illustrates the
Utility's growth rate based on new metered connections over the last 4 years plus the
projected growth for FY 2009-10. It is projected that growth rates will increase to 75 new
metered connections annually from FY 2010-11 through FY 2013-14 which is also consistent
with the Town's financial planning.

DEBT SERVICE COVERAGE REQUIREMENTS
During this water rates analysis process, staff modified the method for calculating the debt
service coverage ratio pursuant to Town Financial Policies adopted by the Town Council in
2008. The adopted policy with respect to debt service coverage ratios states the following:
"When utility revenues are pledged as debt service payments, the Town will strive to
maintain a 1.3 debt service coverage ratio or the required ratio in the bond indenture
(whichever is greater) to ensure debt coverage in times of revenue fluctuation."
The Water Utility currently pays debt service on a number of outstanding debt issuances and
loans. For the Series 2003 Senior Lien Water Revenue Bonds, the 2007 Water Infrastructure
Finance Authority (WIFA) Loan, and the anticipated 2009 WIFA Loan, water utility
revenues are specifically pledged as the repayment source for these obligations at 1.3 times
coverage per the Town's adopted financial policy.
The remaining outstanding debt obligations of the Water Utility are excise tax pledged
obligations meaning that the Town's unrestricted sources of sales taxes, fines, permit fees
and state shared revenues are pledged as the repayment sources for these bonds in the bond
indentures. Even though the bond indentures pledge these excise taxes as the repayment
source, the Water Utility will continue to be responsible for and budget for these debt service
payments at a calculated debt service coverage ratio of 1.0, rather than the 1.3 times
coverage.
It is important to note that the bond indentures for the excise tax -backed bonds require that
the Town's excise tax collections each fiscal year total at least 2.5 times the annual debt
service requirements in order to avoid having to fund a debt service reserve fund. These
conditions have been met annually in the past and are expected to continue in the future.
This methodology of segregating the water utility revenue -pledged debt from the excise tax -
pledged debt in the rates analysis process is an accepted practice in the industry and has been
reviewed by the Town's Finance Director and the Town's financial advisors with Stone and
Youngberg.
The debt service coverage ratio is determined by dividing the annual net operating revenue
by the annual debt service payments. Using the methodology described above is in
accordance with the 2008 policy and reduces the amount of the debt service coverage
requirement amount.
ENTERPRISE FUND
REVENUE
The Enterprise Fund had a cash balance of $10.4 million at the beginning of FY 2009-10.
On July 1, 2009 the Utility paid off the Series 1999 Bonds in the amount of $1.9 million
leaving a balance of $8.5 million for FY 2009-10 expenditures. Enterprise funds may be

used for operating costs including personnel, operations and maintenance, capital

( $ 184,922)
The reduction in water sales resulted in the Utility not meeting the budgeted revenue amount.
The $64,858 received in excess of the service fees budget is due largely to the increase the
Utility received for providing sewer billing services for Pima County Wastewater
rj Reclamation Department. The reduction in interest income is a result of lower interest rates
J experienced with the downturn in the economy.
Revenues projected for FY 2009-10 were based on anticipated annual growth in the customer
base of 60 single family residential customers and water consumption patterns similar to
calendar year (CY) 2008. Analysis of the water use trends for CY 2008 indicated the
average monthly use for a single family residence with a 5/8 x 3/4 inch water declined from
9,000 gallons to 8,093 gallons per month. For this analysis, 8,000 gallons per month was
used to project water sales revenue. This reduction may be a result of increased water
conservation by our customers coupled with the number of homes that are currently vacant,
and commercial and irrigation meters that have been disconnected. The reductions in water
use, along with the vacant and/or disconnected metered accounts, were taken into
consideration when projecting future water sales revenue. The following table indicates the
amount of water sales revenue that would be realized with the existing rate structure and no

Projected personnel costs do not include any new personnel and there are no merit increases
or Cost of Living Allowances (COLA). In FY 2008-09, some vacant positions were filled
resulting in partial -year salaries and benefits for those affected employees. In FY 2009-10,
those positions will be at full -year salaries and benefits thus the increase of $69,808 for
personnel.
The projected operations and maintenance (O&M) costs include the O&M costs for both the
potable water system and the reclaimed water system. Although CAP allotment costs, CAP
Recharge costs and CAGRD costs are included in the O&M budget for the Enterprise Fund,
they are segregated above because of the significant costs of each line item. To appropriately
manage the Utility's financial and water resources, the Utility is limited in the amount of
control it has over these specific costs. The rates are set by the Central Arizona Project and
the Central Arizona Groundwater Replenishment District on an annual basis with projections
for 4 years in the future.
The CAP allotment costs will be less as a result of a rate decrease by Central Arizona Project.
The CAP recharge costs are projected to decrease based on the specific types of CAP water
(incentive priced vs. subcontract priced) and the volume of water that will be recharged at the
Kai Farms Groundwater Water Savings Facility and the Central Arizona Water Conservation
District Facilities. In FY 2009-10, the Utility is proposing to recharge 4,000 AF. Of this
amount 2,500 AF will be at subcontract pricing and 1,500 AF will be at incentive pricing.
The projected decrease in costs for the Central Arizona Groundwater Replenishment District
(CAGRD) is a result of the reduction in water use and continued management of water and
-10-
financial resources. The Utility will use Long Term Storage (LTS) credits to offset a portion
of the costs charged by the CAGRD through permitted recovery wells. In addition, the
recent purchase of groundwater extinguishment credits will help to reduce payment
(j obligations to the CAGRD.
J There are a number of other annual O&M expenses that the Utility has the least control over
and therefore is unable to reduce anticipated expenditures. In addition to the CAP and
j CAGRD costs, some of the other expenses that the Utility has the least control over include:
electrical power for pumping, water quality testing, chemicals for disinfection, potable and
reclaimed water purchased from other providers, software maintenance on existing software,
regulatory permits, insurance, office lease, services provided by other Town departments and
costs directly related to billing. The billing costs include printing of the billing forms,
envelopes, postage, outsource vendor for bill insertion and delivery to post office, lockbox
7 and other bank charges for processing payments. Where applicable, the materials and/or
services have been bid or quotes have been received to assure the lowest price.
The O&M expenses that the Utility has minimal control over include maintenance on
production and distribution facilities such as wells, boosters, reservoirs, and water mains.
The Utility includes known preventative maintenance costs in the budget as well as
contingency funds for unknown repairs and maintenance. The majority of these facilities are
underground which allows for unforeseen malfunctions. Additionally, water mains develop
leaks that must be repaired immediately. The Utility budgets for these specific items based
on historical data; however, it is difficult to predict the exact amount that may be spent in any
given year.
The O&M expenses that the Utility has the most control over include office supplies, field
supplies, memberships and subscriptions, printing, telecommunications, uniforms, rentals,
training, conservation education and outside professional services. The Utility reduced the
J requested budget for these costs in the FY 2009-10 as compared to last year's budget.
Projected debt service will decrease for FY 2009-10 as a result of paying off the Series 1999
Bonds on July 1, 2009. Although the Utility plans on incurring additional debt in FY 2009-
10, it is projected that the initial debt service payment for the proposed WIFA loan will not
be made until the beginning of FY 2010-11.
Debt service payments are established by debt amortization schedules prepared by the
Town's Bond Underwriters for all past bond issues. Likewise, WIFA also provides debt
amortization schedules that the Utility must adhere to. All debt service payments are pre-
defined for any given fiscal year unless funds are available to pay off the debt like the Utility
did in July of this year.
The Utility has financed capital projects in the past and proposes to continue to finance
l projects as necessary in order to spread the costs out over time. This allows the Utility to
Jmaintain the required cash reserves and minimize water rate increases.

Projected capital outlay for existing system improvements in FY 2009-10 include drilling and
equipping 1 replacement well, construction of a 3 million gallon reservoir, water main
replacements and relocations. The reservoir was designated at 50% existing system
improvement and 50% expansion related. As such, the total project cost is split 50-50 with
the Potable Water System Development Impact Fee Fund. Capital outlay also includes the
purchase of water meters, security equipment and other minor assets.
Projected expenditures in the Enterprise Fund are proposed to be funded with revenue
generated from water rates, fees, charges, cash reserves and a loan from the Water
Infrastructure Finance Authority of Arizona (WIFA).
ALTERNATIVE WATER RESOURCES DEVELOPMENT IMPACT FEE FUND
REVENUE
The Alternative Water Resources Development Impact Fee Fund (AWRDIF) had a cash L
balance of $1.6 million at the beginning of FY 2009-10. AWRDIF funds may be used for
capital expenditures related to alternative water resources including reclaimed water and
CAP water. The revenue sources for the AWRDIF Fund are from impact fees collected l
when a water meter is purchased and from interest earned on cash balances. The
Groundwater Preservation Fees (GPF) collected through the Enterprise Fund are transferred
to the AWRDIF Fund to help repay outstanding debt for the reclaimed water delivery system l _
and for future debt on the CAP water delivery system. The following table provides the

The Town Council adopted new impact fees in 2008. The increase in impact fee revenue
7 occurred as a result of the number of large commercial meters that were purchased as well as
the increase in the impact fees.
The decrease in GPF revenue is a result of customers using less water. The water use trends
are discussed in more detail on page 5 of this report.
j Revenues projected for FY 2009-10 were based on anticipated annual growth in the customer
11 base of 60 new connections or 90 Equivalent Dwelling Units (EDUs). An EDU is equivalent
to one single family residence with a 5/8 x 3/4 inch meter. For impact fee projections, the
J Utility converts the estimated new connections to EDUs at a ratio of 1.50 EDUs to 1 new
J connection based on ten year historical trends. In FY 2008-09 the actual growth rate was 615
EDUs.

The acquisition of 3,557 AF of CAP water rights in FY 07-08 will continue to be funded
through the AWRDIF Fund over the next three years. The final payment on the water rights
will be made in December 2011. The costs associated with this acquisition are the capital
costs to build the CAP canal plus interest from inception of the repayment schedule to the
date of acquisition by the Town. This additional water will be necessary to meet the
demands of future customers and as such will be paid from this Fund.
The following table is a comparative summary of expenditures for the AWRDIF Fund. The
following table provides the budgeted expenditures for FY 2008-09 compared to the actual

The professional services are expenses incurred for renewable water studies including the
CAP water pilot study for treatment techniques and the pipeline routing studies for delivery
of CAP water.
The capital improvements in FY 2008-09 represent the completion of construction costs for
the second phase of the reclaimed water system.
The debt service is repayment of the portion of the Series 2003 Bonds used to finance Phase
1 of the Reclaimed Water Delivery System and the 2007 WIFA loan used to finance Phase 2
of the Reclaimed Water Delivery System.
Projected expenditures in the AWRDIF Fund are proposed to be funded with revenue
generated from impact fees, groundwater preservation fees and interest income. In the table

The Utility's FY 2009-10 budget included $3 million for capital improvements related to
land acquisition and engineering and design services for the CAP treatment and delivery
system. It is unlikely that these costs will be incurred in FY 2009-10; therefore, the costs
were not included in the 5 year projection for this Report. When the Utility incurs costs
related to the CAP treatment and delivery system, it is assumed that the project will be
financed through WIFA or the sale of bonds. A partial year of debt service for the project
has been included in FY 2013-14 of this report.
POTABLE WATER SYSTEM DEVELOPMENT IMPACT FEE FUND
REVENUE
The Potable Water System Development Impact Fee Fund (PWSDIF) had a cash balance of
7 $8.9 million at the beginning of FY 2008-09. The PWSDIF Fund was allocated a portion of
the Series 2003 Bond proceeds to finance construction of growth -related potable water
system improvements and the refinancing of the Series 2000 Bond issue. Revisions to the
capital improvement plan due to reduced growth have left sufficient bond proceeds available
to construct the needed improvements for FY 2009-10. It is projected that growth -related
improvements after this time will be paid for with cash.
The revenue sources for the PWSDIF Fund are from impact fees collected when a water
meter is purchased and from interest earned on cash balances. The Town Council adopted
new impact fees in 2007. These new fees became effective in September 2007. The
following table provides the budgeted revenue compared to the actual revenue for FY 2008-

-, The increase in impact fee revenue in FY 2008-09 is a result of numerous new commercial
Jconnections during 2008.
Revenues were projected for FY 2009-10 based on anticipated annual growth in the customer
base of 60 new connections or 90 EDUs. An EDU is equivalent to one single family
residence with a 5/8 x 3/4 inch meter. For impact fee projections, the Utility converts the
t estimated new connections to EDUs at a ratio of 1.50 EDUs to 1 new connection based on
Jten year historical trends. The following table indicates the amount of impact fee revenue

Growth -related potable water system improvements are managed through the PWSDIF Fund.
These improvements include new potable water reservoirs, pump stations, water mains and

reservoir and related piping. This project was designated at 50% existing system
improvement and 50% expansion related. As such, the total project cost is split 50-50 with
the Enterprise Fund. Projected expenditures in the PWSDIF Fund are proposed to be funded
with the remaining Series 2003 bond proceeds and cash reserves generated from impact fees.

PREFERRED FINANCIAL SCENARIO
Prior to developing financial forecasts, financial considerations were evaluated relating to
significant short and long tern capital expenditures, the Utility's existing cash reserves,
n existing outstanding debt, proposed future debt and the related debt service payments. To
l J arrive at a Preferred Financial Scenario, the goals of the Commission were to ensure that all
existing rate setting policies were met, cash reserves were utilized to minimize future debt
(� and proposed rate increases would not result in rate shock. In prior years, a key component in
�J the rate setting process was the calculation of the debt service coverage ratio. A 1.3 debt
service coverage ratio was established by Council policy with the adoption of Resolution No.
(R)05-09. With the implementation of the new methodology to calculate the debt service
coverage ratio, the required debt service coverage ratio is not as difficult to achieve, resulting
in lower rate increases than previously projected. The Commission's finance subcommittee
j� and Utility Staff evaluated different financial scenarios prior to forwarding a
L J recommendation to the Commission.
The Water Utility Commission has made a recommendation for a Preferred Financial
Scenario. The Preferred Financial Scenario generates the revenue needed to maintain an
adequate cash balance of $2.5 million for the Enterprise Fund over the projected five year
period. Additionally, the Preferred Financial Scenario reduces the amount of future
financing by using available cash for capital projects. Coupled with the reduction in
financing, modest rate increases annually allows the Utility to avoid rate shock in future
years.
The Preferred Financial Scenario also builds the cash balance of the Alternative Water
Resources Development Impact Fee Fund over the five year period while we continue to pay
off our current debt on the Reclaimed Water Delivery System. Building this cash balance
will be important as the Town moves forward with the treatment and delivery of Central
JArizona Project (CAP) water.
With regard to the Preferred Financial Scenario, the following are key assumptions used to
develop the financial projections. The entire set of assumptions may be found in Appendix
A.
• Annual growth is estimated at 60 new connections annually which equates to 90
EDUs for FY 2009-10. Projected growth for future years has been estimated at 75
new connections annually which equates to 112 EDUs annually.
• Reduction in water use for FY 2009-10 remains constant throughout the 5 year
period.
• Vacant homes and/or disconnected residential meters will be re -activated at 20% per
1 year beginning in FY 2010-11.
J • The Utility will use cash reserves and a WIFA loan to fund existing system capital
improvements in FY 2009-10.
j • The Utility will continue to use cash reserves to finance existing system capital
J improvements through FY 2011-12.
• The Utility will finance existing system capital improvements beginning in FY 2012-
13.
J -17-
• All 18-hole golf courses will be delivered reclaimed water throughout the 5 year
projection period.
• Debt service for CAP water development begins in FY 2013-14.
• Projected operating costs in FY 2009-10 are similar to the Utility's budget request.
Future years include annual inflation factors after one time expenditures have been
deducted.
• Projected operating costs for direct delivery of CAP water begin in January 2014.
• The Potable Water System Development Impact Fees are not projected to increase
within the 5 year projection period.
• The Alternative Water Resources Development Impact Fees were increased to $4,982
per EDU effective in December 2008. These fees are not projected to increase within
the 5 year projection period.
Analysis of the Preferred Financial Scenario indicates that the Enterprise Fund can utilize
cash reserves to finance a portion of the proposed existing system capital improvements for
FY 2009-10 but will need to finance $3.4 million to complete the capital improvements in
later years. The Preferred Financial Scenario proposes using cash to finance capital
improvements in FY 2010-11 and FY 2011-12. New debt is proposed in FY 2012-13. These
financing assumptions result in a slow decline of the Utility's projected cash balance ranging
from $6.5 million in FY 2009-10 to $2.6 million in FY 2013-14. The projected average
ending cash balance of the 5 year period is $4.4 million.
The Preferred Financial Scenario includes modest increases in the base and commodity rates
in each year throughout the 5 year projection period. The operating and maintenance costs
for direct delivery of CAP water will be paid through water rates; however, the capital costs
to construct the CAP water delivery system will be funded with revenue derived from
Groundwater Preservations Fees and Alternative Water Resources Development Impact Fees.
The financial projections detailed in the Preferred Financial Scenario for the AWRDIF Fund
include assumptions that the repayment of capital costs for the reallocation of 3,557 AF of
CAP water will be funded through the AWRDIF Fund. These payments for the reallocation
began in FY 2007-08 and continue through FY 2011-12. Construction of the CAP water
delivery system will be managed through the AWRDIF Fund. It is estimated that debt
service for this project will begin in FY 2013-14. To help meet the revenue requirements of
this Fund, it has been assumed that the Groundwater Preservation Fees will increase annually
for the five year projection period. The Alternative Water Resources Development Impact
Fees were increased pursuant to Ordinance No. (0) 08-14 adopted in 2008.
The financial projections detailed in the Preferred Financial Scenario for the PWSDIF Fund
include assumptions for growth related capital improvements as detailed in the Potable
Water System Master Plan adopted by the Town Council in 2006. In order to pace water
infrastructure construction with new growth demands, some of these projects have been
delayed over the last several years resulting from a growth rate slower than projected. As
such, there are 2003 bond proceeds remaining to fund the capital improvements for FY 2009-
10. The Potable Water System Development Impact Fees were increased pursuant to
Ordinance No. (0) 07-31 adopted in 2007.

The projections for the Enterprise Fund, AWRDIF Fund and the PWSDIF Fund were
� combined to evaluate the overall debt service coverage at the end of each fiscal year.
I l Analysis indicates that, under the Preferred Financial Scenario, the Utility will meet the debt
service coverage requirement established by the Mayor and Council Water Polices and Bond
rj Covenants for all five years. Proformas for the Preferred Financial Scenario may be found in
J Appendix B.
I 1 RECOMMENDATION ON WATER RATES, FEES & CHARGES
n
After reviewing the analysis of the three Funds and their respective revenue requirements
`J
contained in the Preferred Financial Scenario, the Water Utility Commission is
recommending:
�J
• Increase the Groundwater Preservation Fee by $0.20, from $0.55 to $0.75 per 1,000
gallons for potable water use.
n
• Increase the Groundwater Preservation Fee by $0.10, from $0.30 to $0.40 per 1,000
J
gallons for reclaimed water use.
• Increase the commodity rates for potable water rates
o Tier 1 increase of 1.0%
o Tier 2 increase of 1.5%
o Tier 3 increase of 2.0%
o Tier 4 increase of 2.5%
• Increase the commodity rate for the reclaimed water by 1.0%.
• The construction rate for potable water will continue to be $1.00 greater than the
highest tiered rate and will increase from $6.25 to $6.38 per 1,000 gallons.
• The construction rate for reclaimed water will increase by 1.0% and will remain equal
to the reclaimed commodity rate.
• The water use contained within specific tiers will remain the same for each meter
size.
• Increase the existing new service establishment fees to recover labor and material
J
costs.
• Increase the existing reconnection fees to recover labor and material costs.
• Increase the existing backflow permit fees to recover labor and material costs.
J
• Increase the existing refundable security deposits to minimize bad debt write off.
• Increase the existing meter installation fees to recover labor and material costs.

Oro Valley Water, Tucson Water and Metro Water no longer include water usage in their
base rates; however, Marana Water includes 1,000 gallons. Oro Valley, Metro and Marana
all base their rates on 1,000 gallons. Tucson Water's commodity rates are based on the use
of 100 cubic feet which is equivalent to 748 gallons. To simplify the comparison, the rates
for Tucson Water have been converted to represent the charge for 1,000 gallons. For the
most part, the tiered rate structures for all the Water Utilities are similar. A table providing
proposed rates for all Oro Valley Water Utility meter sizes may be found in Appendix C.
Appendix C also contains tables that calculate the dollar increase and the percentage
increase that a customer would experience on a monthly bill under the proposed rates.
Monthly bill amounts are calculated in 1,000 gallon increments for the 5/8 x 3/4 inch meters
and a variety of increments for larger meter sizes.
For comparison purposes, the following table provides a calculation of a monthly bill
amount for a single family residential customer with a 5/8 x 3/4 inch meter for the water
utilities surrounding the Oro Valley Water Utility service area. Direct comparison of raw
base rates and commodity rates is less effective because of the varying rate structures of each
utility. A better comparison is to calculate the cost for specific consumption levels during a
summer month. Please note that these charges only reflect water use fees and specifically
exclude taxes, Groundwater Preservation Fees and similar renewable water resource fees
charged by other water providers.

The typical single family residential customer averaged 8,093 gallons of water per month
j over the course of 2008. As mentioned earlier in this report, for purposes of this analysis, it
J is assumed that the average single family residential water use is 8,000 gallons per month.
Based on this water use, they would experience an increase of $0.43 per month for water
-j used and an increase of $1.60 for Groundwater Preservation Fees. The total monthly
J increase for 8,000 gallons of water used in a month would be $2.03. This represents an 5.6%
increase of which 1.2% is for water use and 4.4% is for the GPF. Each individual customer's
increase in their monthly bill will depend on the volume of water they use. Tables that
calculate the dollar increase and the percentage increase that a customer would experience on
a monthly bill under the proposed rates may be found in Appendix C.

The proposed increase in the GPF will help repay the debt on the reclaimed water system, the
capital charges associated with the reallocation of 3,557 AF of CAP water and ultimately,
repay the debt for the costs to construct the CAP water delivery system. It is proposed that
the GPF be increased gradually over a five year period. In keeping with the Town Council's
direction in prior years, the reclaimed water customers will pay a reduced rate for the GPF.
ALTERNATE FINANCIAL SCENARIO
Appendix D presents an Alternate Financial Scenario to allow for a comparison with the
1 Preferred Financial Scenario. Both scenarios used identical assumptions for growth, water
J use trends and operating costs. A significant difference is the timing and amount of the
proposed future debt. In the Alternate Financial Scenario, it is assumed that the Utility
l would borrow money for capital projects in FY 11-12 and FY 12-13 and use cash for all
J projects in FY 13-14. This financing assumption results in the Utility maintaining
approximately $5 million projected cash balance in all years except FY 13-14 in which the
projected cash balance would drop to $2.2 million. The projected average ending cash
balance of the 5 year period is $4.9 million.
21-
The only other difference between the two scenarios is that there are no increases in the base
and commodity water rates. The proposed increases to the GPF are the same in both
scenarios. The Alternate Financial Scenario includes the following:
• Increase the Groundwater Preservation Fee by $0.20, from $0.55 to $0.75 per 1,000
gallons for potable water use.
• Increase the Groundwater Preservation Fee by $0.10, from $0.30 to $0.40 per 1,000
gallons for reclaimed water use.
• Increase the existing new service establishment fees to recover labor and material
costs.
• Increase the existing reconnection fees to recover labor and material costs.
• Increase the existing backflow permit fees to recover labor and material costs.
• Increase the existing refundable security deposits to minimize bad debt write off.
• Increase the existing meter installation fees to recover labor and material costs.
Given the current economic conditions, the Water Utility Commission and Utility Staff
wanted to provide an option for the Council to consider with regard to water rates. The
Alternate Financial Scenario proposes no rate increase for the base rates and the commodity
rates in FY 2009-10 as opposed to the 1.2% rate increase that is proposed in the Preferred
Financial Scenario. The Alternate Financial Scenario does not have the rate increases that
will generate needed revenues and therefore further reduces the ending cash balance in FY
2013-14. In order for the Alternate Financial Scenario to meet all the financial requirements,
the scenario included debt financing of $5.9 million in FY 2011-12.
The following table illustrates the proposed financial impact of the Alternate Financial
Scenario during the 5 year projection period for proposed rate increases, GPF increases, the
total financial impact and the projected monthly bill for a single family residential
customer using 8,000 gallons of water per month.

OTHER SERVICE FEES & CHARGES
n
Both the Preferred and Alternate Financial Scenarios include the same increases in other
service fees and charges as listed below. The schedules for these proposed increases are
n included in Appendix E. None of these service fees and charges are development impact
i J fees.
NEW SERVICE ESTABLISHMENT FEES
New service establishment fees provide the Utility a means of recovering labor and material
costs related to performing new service establishment procedures. The costs related to new
service establishment procedures include staff labor, printed forms and vehicle costs. It is
recommended that the new service establishment fees be increased to recover the costs to
provide the service.
RECONNECTION FEES
Reconnection fees provide the Utility a means of recovering labor and material costs related
to performing delinquent turn off procedures. The costs related to delinquent account turn
off procedures include staff labor, vehicle costs, printed forms, out -source mailing expenses
and postage.
BACKFLOW PERMIT FEES
Backflow permit fees provide the Utility a means of recovering labor and material costs
rl
related to inspect new backflow assembly installations, maintain a backflow data base,
J
notification to owner of testing requirements and following up to insure that the testing was
completed and is in compliance with State regulations. The costs related to backflow permit
fees include staff labor, vehicle costs, printing costs and postage.
SECURITY DEPOSITS
Security deposits are required of all new customers establishing water service with the Utility
for the first time and are refundable after one year if the account has not been delinquent.
Security deposits are also required if an existing account becomes delinquent. Currently, the
Jsame
deposit is required regardless of the customer classification.
Recent trends indicate that the majority of customers closing accounts without paying their
final water bill are tenants. These customers frequently have delinquent accounts prior to
leaving, thus the amount owned is typically more than one month's water use.
"1 METER INSTALLATION FEES
J There are currently over 18,000 water meters in the water distribution system. Water meters
are the equipment that measure the volume of water used in order to bill each customer for
l their specific water use. Water sales revenue represents 93% of the total revenue collected
J for the Enterprise Fund. The meter installation fees need to be increased to recover the labor
j and material costs related to meter installations.
J No other adjustments to service fees and charges are necessary at this time; however, the
Commission recommends that the service fees and charges continue to be reviewed on an
annual basis.

CONCLUSION
The Commission presents this Water Rates Analysis Report for the review and consideration
of the Mayor and Council. The Commission and Water Utility Staff are available to discuss
this report in greater detail at Council's request. Utility Staff are planning to request
Council's approval of a Notice of Intent on October 7, 2009 and approval of any rate ( ,
increases at a Public Hearing on November 18, 2009. r l
The Oro Valley Water Utility Commission is proud to serve the Town of Oro Valley, it t

l l SERVICE FEES & CHARGES
Security Deposits:
l l Purpose: To provide the Utility a means of recovering water sales revenue when a
customer closes a water service account without paying their final water bill.
Security deposits are charged to all new customers that do not have an
existing account with the utility. These deposits are refunded to the customer
after one year unless the account has been delinquent.
Recent trends indicate that the majority of customers closing accounts without
paying their final water bill are tenants. These customers frequently have
a delinquent accounts prior to leaving, thus the amount owed is typically more
than one month's water use.
With regard to commercial accounts, other regional water providers increase
the amount of the security deposit based on meter size or two times the
estimated monthly water bill.
Costs: There are no costs associated with security deposits; however, if there is no
security deposit when a customer leaves without paying their final bill, the
Utility loses that water sales revenue.
Due to the increase in the number of customers leaving the service area without paying their
final water bill, it is recommended that Security Deposits increase as shown:

Assumptions:
Sensus Meter & AMR equipment costs quoted by Dana Kepner.
Average meter reader labor is $21.53 per hour including 30% benefits.
Rounded labor costs to $25.00 per hour to include costs for gasoline, uniforms, phones, & administration.
Average distribution labor is $27.50 per hour including 30% benefits.
Rounded labor costs to $30.00 per hour to include costs for gasoline, uniforms, phones, & administration.
Use of Omni meters for 1.5 and 2-inch meters are proposed because of the following reasons:
C2 meters measure flow as low as .5 gpm and up to 200 gpm
The current meters being used measure flow from 2 gpm to 200 gpm
T2 meters measure flow as low as 1.25 gpm up to 200 gpm (1.5-inch)
The current meters being used measure flow from 4 gpm to 120 gpm
T2 meters measure flow as low as 1.5 gpm up to 200 gpm (2-inch)
The current meters being used measure flow from 4 gpm to 160 gpm
Additionally C2 & T2 meters can be tested without removing the meter and has data logging
capability to record up to 31 days of of water use on an hourly basis.
