HomeMy WebLinkAboutTask Order No. 10069 with Murray Smith and Associates, Inc. for Water Master Plan• TASK ORDER 10069 WATER MASTER PLAN CITX OF MERIDIAN,1[DAkIO • This Scope is for Professional Services between Murray, Smith & Associates, lne. (MSA} and the City of Meridian, Idaho (City). This proposal shall be for professional engineering services to develop a Water Master Plan (Plan). This Plan will evaluate the ability of the City's existing infrastructure to meet projected demands and regulatory requirements for the next 20 years. The terms of this work shall be in accordance with the MSA Master Agreen:eat for Ptn~essiona! Services, dated Juste 11, Zt1U7. Background This project will serve to provide the City with a Department of Environmental Quality (DEQ) approved Plan to specifically address the water system specific section. of 5$A1.0$ of the ldaho Code. This Ptan will serve as an update to previous water planning efforts conducted by the City that focused on existing and future supply as well as water quality regulations. It will also include new sections on operations and maintenance, source water protection, conservation, water supply planning as well as design and construction standards. The project will employ workshops to solicit stafyinput and develop consensus on what alternatives should be selected for future implementation. A 20 year capital improvement plan will be generated at the conclusion of the PIan that will describe the projects in a prioritized order and provide order of magnitude costs. The City has experienced very high growth rates over the past 20 years while the past two years have been relatively flat, illustrating how variable growth can be. The City is committed to updating their water master plan every five or so years. which enables them to provide course corrections on the longer term water use and capital improvement projections. The Gity's goal is to provide a detailed analysis of what is required over the next five years while also having a longer term capital improvements vision.

Task ~ -Population and Demand Pxojeetlons The development of future population growth and associated water demand projections is a fundamental building block for determining the City's future needs. Of equal importance is understanding where in the system growth will occur so that infrastructure is adequately sized. In this Task, MSA will work with the City to develop and describe these items. Several pieces of information will be required to successfully project population and demands including: • Current and future service area boundaries • Location based population and employment information • Pressure zone delineation • Historical water usage by customer location City of Meridian, Idaho MURRAY, SMITH & ASSOCIATES, INC. Water Master Plan January 2010 Fngineers/Plamie~rs 4 of 21 • • Historical water production records • 20 year population and employment projections Current population and water production records will be used to determine per capita demands that can then be used for future forecasting. Historical SCADA will be used to determine the appropriate peak day and peak hour factors that should be used, The City has recently undertaken an aggressive reuse program at the wastewater treatment facility. This in conjunction with the more formalized conservaxion planning that is currently being undertaken may reduce the amount of water consumed by each customer in the future from an annual average as well as peak perspective. MSA would propose to develop two (2) different water use growth rates for the next 20 years. This would include a growth rate assuming per capita water use rates do not change significantly from those seen today and a second that assumes at least a modest reduction due to an active conservation program. This reduction may be in the order of 10 to 20 percent, but more importantly it will provide numbers to evaluate the capital investment impact of trying to actively promote conservation versus staying the current course. The percentage to use will be identified in Task 5 as part of the conservation planning effort. Within the last two years MSA has made population projections fvr the City using COMPASS information. MSA would propose to utilize this process again unless other City Comprehensive Planning data can be provided. The COMPASS data utilizes traffic analysis none (TAZ) based data that can be overlayed with the City's service area and pressure zones. It is the intent of the Plan to tie future improvements to population and the related water usage thresholds, not necessarily dates in time. This will enable the City to utilize maximum day demands (MDD) for example, as "trigger points" for determining when new supply or storage should be constructed. Assumptions • MSA will utilize COMPASS based planning data unless other information is provided. • Five (5) and twenty (20) year projections will be made for population and demand by pressure zone. Deliverables • A Draft Technical Memorandum (electronic version} summarizing the population and demand projections. Task 5 -Water Supply Planning Subtask S.1- Couservation Flag Development The City currently does not have a formalized conservation plan. This subtask would provide the basis for the development of a conservation plan that could ultimately serve as a City of Meridian, Idaho MURRAY, SMITH & ASSOCIATES, INC. Water Master Plop January 2610 Engineers/Planners 5 of 21 • stand-alone document. Some of the initial steps required for the development of a conservation plan are already included in the overali Water Master Pian and can be leveraged for use in this subtask. This includes reviewing the existing demand forecast and describing the water system. MSA would propose the conservation plan include the following steps: l . Idenrify any existing conservation measures 2. Define conservation potential 3. Identify potential conservation measures 4. Perfi'orm cost/benefit analysis 5. Select conservation measures 6. Summarize Phase 1 and longer teen conservation goals 7. Document conservation plan MSA would conduct a conservation planning workshop with City staff to discuss, existing conservation measures, formal or informal. A large portion of the workshop would be spent discussing potential conservation measures that could be implemented that are specific to the City of Meridian such as; leak detection, sowce and customer meter maintenance, pressure reductionlmanagement, inclining block rate structures, conversion of neighborhoods or commercial/governmental users to non~potable irrigation, public education programs, appliance rebate/replacement programs, smart irrigation control systems, establishing a City Conservation Coordinator and water conservation ordinances. The City may choose a number of these to evaluate from acost/benefit perspective for phase 1 implementation. City staff will then take the lead in evaluating and documenting various conservation measures. The City will then prepare information to be used. in a second workshop to discuss the findings of the cvst/benefit analysis and to make recommendations for which measures should be implemented, which MSA will attend. MSA will make suggestions based on previous experience on the City's conservation planning. The City will prepare a document summarizing the Phase 1 conservation goals and longer term goals wilt be developed. MSA will review this document and provide any additional recommendations that maybe incorporated. Assumptions • The City will take the lead in developing the conservation chapter and will provide a written document in Microsoft Word format that includes all required information. • Two conservation workshops are included in the scope of work • The conservation plea will be included as a chapter in the Plan. • No additional council presentations or meetings have been included in the budget for the conservation planning.

Deliverables • A document summarizing the City's existing water rights planning efforts and strategy will be provided to the City as part of the overall Water Supply section. Subtask 5.3 - Interties The City has opportunities in a few locations to create emergency interties with adjacent public water purveyors. This would likely provide a two way flow of water under emergency conditions. The City has existing locations already identifed and this subtask would simply provide a review of those locations and document the assumptions associated with their operation. A map including the location of the potential interties would be included in the document. Assumptions No time has been budgeted to conduct discussions with adjacent purveyors on the details of an interagency agreement regarding the interties.
