Santa Cruz River and Canada del Oro Wash; and
1.9 WHEREAS, Pima County Flood Control District and Reclamation hereby agree
that contract number 01-04-U-123237-0797 will be terminated according to the provisions of
that contract, and that this Agreement replaces contract number 01-04-U-123237-0797, which
was entered into on July 15, 1997 by and between the Pima County Flood Control District and
Reclamation.
NOW, THEREFORE, in consideration of the covenants and conditions herein contained,
Parties agree as follows:
2. INTRODUCTION AND PURPOSE
2.1 The purpose of this agreement ("Agreement") is to provide a framework for the
joint conduct ofSARWMS, and define the obligations of the Parties relative to the Study.
Reclamation provided funding in Fiscal Years 1997, 1998 and 1999, and may provide funding
in Fiscal Year 2000. The General Investigation Program requires cost sharing with local
sponsors. The Towns ofOro Valley and Marana, MDWID, and the Pima County Flood
Control District will participate as Local Sponsors.
2.2 The purpose of SARWMS is to coordinate and integrate the planning efforts ofthe
northwest T AMA water providers to develop a comprehensive water management plan for the
northwest portion of the T AMA.
.!.
2.3 The purpose of this Study is to develop a comparative analysis of four water
supply alternatives for the northwest T AMA. A study objective includes identifying long-
range needs and matching them with available and appropriate supplies, including
groundwater, CAP water and effluent.
2.4 The role of Reclamation in this Study is to fund a portion of the Study, and
provide project management and oversight for the Study. Reclamation will work with the
, ,
Local Sponsors to develop a comparative analysis of four water supply alternatives for the
northwest T AMA as described in Attachment "A". Because the basis for cost estimates of
three of the four alternatives have already been largely completed, the emphasis of this Study
will be to develop the cost estimate for the remaining water supply alternative (alternative 3,
Attachment "A").
3. SERVICES TO BE PERFORMED
3.1 The Parties hereby agree that an employee of Reclamation shall be the Project
Manager, and that said Project Manager shall perform and carry out the duties and
responsibilities required to accomplish the Work Plan as outlined in Attachment "A" of this
Agreement.
3.2 Reclamation shall, with its staff or by contract, use appropriated funds and
contributed in-kind services to complete the Work Plan as set forth in Attachment "A", to the
extent that in-kind services are provided by the Local Sponsors, and Federal funds are
appropriated for this purpose.
3.3 The Local Sponsors shall work with Reclamation, and shall provide guidance and
information as appropriate, and review work products.
3.4 Upon completion of the Study, Reclamation shall transmit to the Local Sponsors
the report as described in Attachment "A".
4. TERM OF AGREEMENT
4.1 This Agreement shall become effective upon the date an executed copy is recorded
and shall remain in effect until completion of the Study report, but in no event later than June
30,2000, unless either Party terminates work pursuant to Article 11 herein. The Parties hereto
anticipate that the draft Study report will be completed no later than December 31, 1999, and
the final Study report will be completed no later than March 31,2000. If work is terminated
pursuant to Article 11, this Agreement will terminate in ten (10) days following written notice.
5. COORDINATION AND PROGRESS REPORTS
5.1 A Study Management Team (SMT) shall be formed to oversee the development of
the Study alternatives, level of detail of the Study and conformance with Study goals. The
SMT shall consist of one representative from Reclamation, one from each of the Local
Sponsors, one from members who qualified under the Northwest Replenishment Program, and
one from members who qualify under Section 5.2 below.
~
,
'"
.i.
5.2 New members shall be added to the SMT if resources equaling or exceeding
$100,000 are committed to the Study. These resources may be cash, in-kind services, use of
consultants, or some combination thereof. The criterion for acceptability of a contribution is
approval of the sponsor's governing body, where necessary, and acceptance of the
contribution by Reclamation as qualifying for local matching funds for the study.
Reclamation shall determine whether the contribution is acceptable based on consistency with
the Work Plan (Attachment "A").
5.3 For purposes of dis~ussion, the SMT may include more than one
representative from each Project Sponsor. However, for purposes of resolving issues,
only one representative from each Sponsor shall have a designated right to vote.
5.4 Each Local Sponsor shall maintain an accounting of its contributions to this
Study, and shall provide an accounting to Reclamation when so requested by
Reclamation.
6. STUDY FUNDING
6.1 Reclamation shall perform portions of the Work Plan as documented in
Attachment "A", except that total Reclamation cost-share contributions shall not exceed
50% of the total cost of the study. The total cost-share contributions of the Local
Sponsors shall, at a minimum, equal Reclamation's cost contribution to the Study.
6.2 If, during the Study term, projections of Study costs indicate that the available
funds may be exceeded, Reclamation and the Local Sponsors' Study representatives shall
be notified. Should the Local Sponsors or Reclamation be unable to arrange for
appropriate funding or in-kind services, Study activities may be suspended until the Work
Plan is reconciled with the existing funding program, or other options are identified that
are acceptable to the Parties of this Agreement.
7. IN-KIND SERVICES
7.1 As determined by Reclamation, services provided by the Local Sponsors
which are consistent with the Work Plan in Attachment "A" and which would otherwise
be performed by Reclamation, shall be deemed to be "in-kind" services.
7.2 The value of in-kind services provided by the Local Sponsors shall be
credited toward the payment of the local cost-share, as documentation is received by
Reclamation that said in-kind services have been accomplished. The value of those
services will generally be compared to what it would have cost Reclamation to provide
the same service.
.l.
c
7.3 The following pre-Agreement activities qualify as local matching in-kind
services, subject to adequate documentation being provided to Reclamation:
~
.
a. Southern Arizona Regional Water Management Study
development costs incurred by the Local Sponsors, as approved by

ATTACHMENT "A"
WORK PLAN
SOUTHERN ARIZONA REGIONAL WATER MANAGEMENT STUDY
Background
Central Arizona Project (CAP) water was first introduced into the Tucson area in 1992.
Problems experienced during initial deliveries have led to a reassessment of local plans for
using CAP water, as well as a reassessment of the relationships among various local water
providers.
To date, there are no firm regional water resources plans to integrate CAP water supplies with
existing supplies within the Tucson Basin. In addition, there is a need to study and possibly
implement localized distribution system improvement and coordination projects. The Towns
of Oro Valley and Marana, the City of Tucson, and the Metropolitan Domestic Water
Improvement District are all performing separate studies of future water supply alternatives.
In order to assist in the development of an overall regional plan to provide water to the
Northwest Tucson area, the Bureau of Reclamation (Reclamation) is sponsoring this study,
referred to as the "Southern Arizona Regional Water Management Study".
Issues to be Addressed
There are a number of important issues that must be considered relative to future water
resources planning for the study area. These are as follows:
- CAP allocations, water use methods, and requirements
- CAP terminal storage facility requirements, sizing and locations
- CAP service reliability and sustainability
- CAP water quality
- Potential for localized distribution system coordination
- Aquifer recharge capabilities
- Aquifer safe yields
- Present and future ground water quality
- Present and future water treatment costs
- Environmental impacts of CAP imports, recharge and effluent reuse
- Present and future delivery system infrastructure
- Institutional restrictions and requirements
- Public perceptions of water resource management activities
,
..
"
Studv Activities Overview
:
The development and analysis of water resources management and distribution system
alternatives are to be the focus of activities in this regional study. Portions of the activities
discussed in this Work Plan have been performed for other studies, but not integrated into the
overall plan for the study area. Relevant material will be incorporated into this study.
Specific study activities will include a water supply and demand assessment; an inventory of
existing and associated problems; an inventory of institutional constraints; the development
and analysis of water supply alternatives; the development and analysis of distribution system
operational improvement through cooperation among water providers; and the development of
preliminary designs and cost estimates. Division of work will enhance a sense of ownership
in the results among the study participants and will provide for cost sharing as required for
Reclamation funding.
CAP reliability issues need to be looked at beyond those previously considered by
Reclamation. Reclamation has informed the northwest water providers that CAP reliability
features may be considered for direct delivery of CAP water alternatives.
Water Supply Assessment
The purpose of the water supply assessment will be to consolidate knowledge about how each
agency provides water to its customers; what each anticipates its present and future demands
to be; and to ascertain the quantity and quality of water resources that will need to be
developed in the future. The following activities will be performed in this study:
- Inventory existing and historic demand, and estimate future demand
- Inventory historic and existing water quality
- Identify future water quality objectives for import and/or reclaimed water
- Inventory existing infrastructure, and identify problems and needs
- Identify operational restrictions in distribution systems
- Identify overdraft areas
- Estimate safe yields without artificial recharge
- Identify requirements for import water (new water and/or reclaimed)
- Develop task summary report
Institutional Inventory
The development of an inventory of institutional constraints and requirements that affects the
regional management of water resources will be identified and summarized, as indicated in the
following task list:
.1
~
-;
- Identify Local, State and Federal Water Resources Policies, Agreements, and
activities
- Identify Federal project authorizations
- Summarize Southern Arizona Water Rights Settlement Act of 1982
- Identify CA WCD policies and agreements
- Summarize Ground Water Management Act of 1980 (A WS Rules)
- Summarize Ground Water Recharge and Underground Storage Act of 1986
- Summarize Arizona groundwater replenishment district policies and agreements
1
.
..
"'
_ Summarize pertinent State and Federal water quality regulations
- Develop task summary report
Alternatives Development
Several alternatives have been developed in other studies. Due to the limited financial and
human resources available for this study, an initial assessment will lead to the selection of up
to five alternatives for further analysis. The regulatory, financial and economic implications
of implementing each alternative, as well as the benefits, will be assessed.
There are a number of regional water supply issues that will be considered in shaping
alternatives in the SAR WMS. These are listed below:
- CAP water allocations
- CAP terminal storage locations and requirements
- CAP delivery costs
- Impacts of direct use of CAP water on infrastructure and water quality
- CAP, terminal storage, and distribution system reliability
- CAP water deliveries to recharge projects
- CAP water quality impacts on groundwater from recharge projects
- Blended use of CAP and groundwater
- Treatment plant and distribution system requirements
- Effluent treatment and reuse objectives
- Water conservation practices
Potable water supply alternatives that are being considered include:
1. Continued use of groundwater - Under this scenario, groundwater replenishment
can take place anywhere in the Active Management Area. Meets the "letter of the
law" for Assured Water Supply.
2. Recharge and recovery of CAP water - This alternative was studied in depth for the
Canada del Oro Project. The Lower Santa Cruz Project could provide recharge and
recovery primarily for the Marana portion of a regional system. This alternative
assumes that the northwest water providers want to go beyond the "letter of the law"
and want to use wet water in their delivery system.
3. Direct use of CAP water from a new water treatment plant - Assumes CAP water is
treated to primary drinking water standards using filtration and disinfection. Location
of a water treatment plant (WTP) will be based on several factors, after the analysis of
the water providers' distribution system plans has been completed.
4. Direct use of CAP water from the Hayden-Udall WTP - Assumes CAP water is
treated to primary drinking water standards using filtration and disinfection at the
Hayden-Udall WTP and is then delivered to the northwest water providers. This
scenario represents the original planning that Tucson Water had developed.
Localized Distribution System Imorovement and Cooperation Alternatives
Another main purpose of this study is to develop and analyze alternatives for localized
distribution system improvements, and related opportunities for cooperation among local
water providers in the northwest metropolitan area. This study will result in a number of
recommendations to help resolve how distribution system infrastructure improvements and
cooperative agreements can assist the northwest area water providers in serving their
customers and in meeting future growth requirements.
Modeling and Analysis of Distribution System Alternatives
The distribution system alternatives will be evaluated through the development and
application of a distribution system network model. This model will have the capability of
simulating pipe network deliveries to demand centers within the northwest area. Simulation
output would provide information about pipe network flows, pressures, and storage volumes.
The main function of the model is to size the pipeline and reservoir facilities identified in each
alternative. Results of network model simulations will be presented in tabular and graphical
form.
Preliminary Design and Economic Analysis
A cost estimate, which will include capital costs as well as operational and maintenance costs,
will be performed for each alternative. This information, combined with performance related
information from the network modeling and the results of the evaluation of regulatory
implications, will provide the basis for the selection of a preferred alternative.
Public Involvement
It is unclear, at this time, whether extensive public involvement will be required. It does,
however, seem appropriate to hold public meeting to present study results and conclusions. A
comprehensive program to educate the public relative to all aspects of implementation of the
preferred plans will be the responsibility of the northwest water providers.
~
:
Environmental Studies
The resources provided for the SAR WMS will not be sufficient to perform detailed
environmental impact analyses. Detailed studies would be a next logical step towards the
implementation of a preferred alternative. However, a preliminary study of the environmental
impacts of the preferred alternatives will be performed.
Strategy
Proposed infrastructure information supplied by each water provider will serve as the basis for
beginning to design the pipeline for direct delivery of CAP water. Information on proposed
infrastructure can also be used to begin identifying potential operational coordination benefits.
1. Reclamation will develop feasibility level designs and cost estimates for the main
delivery pump stations and pipelines for alternative 3 (direct use of CAP water from a
new water treatment plant).
2. Each water provider, working with Reclamation, will develop feasibility level
designs and cost estimates for infrastructure from the turnout off of the main pipelines.
3. Develop distribution system operational improvement/cooperation alternatives.
4. Reclamation will begin performing feasibility level designs for an "integral"
