Henderson, Water Division Manager SUBJECT: WATER REUSE MASTER PLAN CAO RECOMMENDATION 1. Adopt resolution authorizing application for a grant from the State Water Resources Control Board for the Water Reuse Master Plan,and, 2. Approve the request for proposals and authorize staff to solicit proposals for the Water Reuse Master Plan. DISCUSSION The City of San Luis Obispo has been pursuing development of the Water Reuse Project for many years. The plans and specifications for the Water Reuse Project are currently being finalized and project construction is expected.to begin in early 2003. The current project will construct the necessary improvements at the Water Reclamation Facility and the distribution system needed to deliver water for uses in the southem part of the City. As part of the 2002 Water Resources Status Report discussions on June 11, 2002, the Council endorsed the concept of the development of a Water Reuse Master Plan to identify future logical extension of the water reuse distribution system.. The State Water Resources Control Board has a Water Recycling Facilities Planning Grant Program that provides up to $75,000 fordevelopment of planning documents such as the proposed Water Reuse Master Plan. The grant funds require matching local funds on a 50-50 basis. If the State grant is approved, the State will reimburse the City for allowable expenses up to the $75,000 limit. The proposed master plan would identify the logical expansion of the reclaimed water distribution system to allow full utilization of the available water from the Water Reclamation Facility. The plan will develop a long-term (approximately 20 year) plan for incremental extension of pipelines and related facilities to potential sites throughout the City. The full scope of work is provided in Attachment 2, "Request for Proposals for the Water Reuse Master Plan". FISCAL IMPACT The development of a Water Reuse Master Plan was not included in the 2001-03 Financial Plan. The funding necessary(City's match) to support this project will be appropriated from Water Fund Balance once proposals are received and consultant recommendation is provided to Council for approval. Staff will return to Council for approval of necessary funding following the State's decision of approval of the grant. (1/0-/ Council Agenda Report-Water Reuse Master Plan Page 2 Attachments: 1.

Introduction The City of San Luis Obispo is seeking proposals from qualified consulting firms for preparation of a Water Reuse Master Plan. The Master Plan will identify the logical expansion of the Water Reuse system, beyond the current planned system, to provide up to 600 acre feet of additional recycled water throughout the City of San Luis Obispo over the next twenty years. It should be noted that the chosen consultant will be asked to meet with staff after being chosen and before the contract is negotiated to clarify the work to be done and the final contract costs. The consultant will also include in the work schedule ample time for staff and consultant to assure the proiect is executed in a collaborative process and that the final product meets the City's needs. Background The City of San Luis Obispo is currently pursuing construction of a Water Reuse Project which will serve the southern portion of the City as shown in Figure 1. The City currently produces tertiary treated wastewater that meets Title 22 requirements for non-potable uses. The City has completed all environmental analysis required for the use of the recycled water and has been granted modifications to the discharge permit for the effluent to allow the use of the water by the State Water Resources Control Board. The City has also completed Section 7 consultation with the National Marine Fisheries Service and the biological opinion for the project has been issued to the City. Conditions of the biological opinion require minimum discharges from the Water Reclamation Facility to San Luis Obispo Creek to minimize potential impacts to the downstream habitat and species. Based on the minimum discharge requirements noted above, the Water Reclamation Facility has the potential to produce 1,233 acre feet of recycled water per year for use throughout the City. Following initial construction of the first phase of the distribution system, it is estimated that approximately 138 acre feet of recycled water will be used. Over the first five years, use is anticipated to increase up to approximately 1,000 acre feet per year. Much of the additional use will involve exchanges with agricultural areas for use of potential potable groundwater resources. The following are studies that have been completed which may be useful in developing a more thorough understanding of the issues associated with the Water Reuse Project. ❑ "Water Reclamation&Beneficial Use Investigations,August 1988" ❑ Draft"Water Reuse Project, Engineering Report,February 2000" E3 Final "Water Reuse Project, Engineering Report, October 2001" The draft engineering report above, envisioned a much larger initial project which would have delivered recycled water to many more locations throughout the City. The final report identified the current project which will serve only the southern portion of the City as previously noted. _�_ C/U-S� Attachment 2 FIGURE 1 Mto anWisoBispo Water Reuse Project `a [�..=. l v� JOE 40 —� 200 f �. 20 Water Reclamat M Faal 71 City of san LUIS OBispo` RoPosea y °Stationard \ LEGEND ./ mommism pMJw Pl*he MRS=Proposed Use Areas ' wma■•m Gmwdwater Exdwqe Plpellne posslele Fuwm Use Are 0 Potenbal for GrourWwater nge 20 Armual Corrsum bw in A,o- .m- 20 Annual CansurrotiOn Future Users 2 Attachment 2 Available Resources The City of San Luis Obispo has developed a Geographic Information System(GIS)which will likely be valuable in the preparation of the Water Reuse Master Plan. The system has many layers of information which includes: aerial photographs, land use designations, street right-of-ways, topographic information, waterlines, sewerlines, etc. The City can provide the consultant the available GIS information on CD's for their use for this project. There is a charge of$200 per CD with aerial photographs provided on one CD and all other information provided on a second CD. The consultant shall include these costs in their proposal if these resources are deemed necessary for the project. Scope of Work Based on the current design for the Water Reuse distribution system shown in Figure 1, the consultant shall identify potential sites throughout the City which could utilize recycled water for irrigation purposes. The goal is to identify uses for up to an additional 600 acre feet per year while minimizing overall project costs. The consultant shall identify numerous route alternatives to meet the project goals and evaluate the overall cost for each alternative which will include capital costs as well as operation and maintenance costs. The consultant shall also address potential storage needs for an expanded system. Previous studies have identified Terrace Hill as a potential storage tank site. Based on pipeline route alternatives, the consultant shall identify and evaluate other potential locations for storage. The system shall be designed to provide a minimum of 50 psi at each location/site. A hydraulic analysis of potential alternatives shall be prepared to identify proper pipe sizes, storage needs, booster pumps and other needed facilities to meet the required design parameters for the system. The consultant shall meet with City staff prior to submittal of the draft report to discuss the various pipeline/system configurations to evaluate which alternative should be selected as the preferred project. The decision of the preferred alignment will likely take into account other factors besides just overall project costs, such as community impacts, visual impacts, traffic impacts, etc. Once the preferred alternative is agreed upon,the draft written report shall be prepared and submitted to the City. The draft report shall discuss the various alternatives analyzed, identify the preferred alternative(s) and the reasons for selection of the preferred project. In addition, the consultant shall prepare a strategy for construction of the system over a long-term period (approximately 20 years) to allow the City to incrementally increase the use of recycled water while maintaining relatively constant annual capital expenditures for the project. 3 e10- 7
