CC 2014-09-23_08.c. Recycled Water Planning StudyMEMORANDUM TO: CITY COUNCIL FROM: TERESA MCCLISH, COMMUNITY DEVELOPMENT DIRECTOR SUBJECT: CONSIDERATION OF PARTICIPATION IN A RECYCLED WATER FACILITIES PLANNING STUDY AND GRANT APPLICATION FOR A SATELLITE WATER RESOURCE RECOVERY FACILITY FOR THE SOUTH SAN LUIS OBISPO COUNTY SANITATION DISTRICT DATE: SEPTEMBER 23, 2014 RECOMMENDATION: It is recommended the City Council 1) approve participation in the preparation of a grant application and Recycled Water Facilities Planning Study (Study) for a potential Satellite Water Resources Recovery Facility (SWRRF) for the South San Luis County Sanitation District (SSLOCSD); and 2) appropriate $40,877 from the Water Fund for the City’s portion of the study and matching costs. IMPACT ON FINANCIAL AND PERSONNEL RESOURCES: It is recommended the City split the costs with the SSLOCSD. The total cost of the study and application is anticipated to be $156,700. Each agency would pay $40,877. The remainder of the cost would be paid by the grant provided through the State Water Resources Control Board’s (SWRCB) Water Recycling Facilities Planning Grant Program. Staff work would need to be dedicated to the project, but water resources is a priority goal in the City’s Critical Needs Action Plan. BACKGROUND: The Water Recycling Funding Program (WRFP) provides grants to assist public agencies with facilities planning studies to determine the feasibility of using recycled water to offset the use of fresh/ potable water from the state and/ or local supplies. The grant will cover 50 percent of the eligible costs up to a maximum of $75,000. The SSLOCSD provides wastewater treatment services for the City, as well as the City of Grover Beach and the Oceano Community Services District. Groundwater supply for these member agencies may be severely impacted due to drought conditions. On June 7, 2012, a public Water Recycling Forum was held at the South County Regional Center. In recent years, agencies have recognized that Water Recycling will be a necessary component of meeting our future water demands in the South San Luis Obispo County Area. Water Recycling can help to effectively manage groundwater resources, protect water quality, and meet California Recycled Water goals. Item 8.c. - Page 1 CITY COUNCIL CONSIDERATION OF PARTICIPATION IN A RECYCLED WATER FACILITIES PLANNING STUDY SEPTEMBER 23, 2014 PAGE 2 ANALYSIS OF ISSUES: At the City Council meeting of June 10, 2014, the Council directed staff to pursue grant opportunities for recycled water projects in order to provide long term protection of the groundwater basin. The development of a recycled water project such as the SWRRF could be used to offset groundwater pumping or provide recharge to the groundwater basin and improve water supply reliability for the City. Opportunities have been identified by SSLOCSD consulting staff that include locating a SWRRF adjacent to the Arroyo Grande trunk sewer line in the general vicinity of land south of Arroyo Grande High School. This project would intercept effluent prior to it entering the SSLOCSD plant within or immediately adjacent to the City and as such would create benefits directly to the City. Potential benefits of the satellite facility include: improved jurisdictional control; fewer permitting obstacles due to location outside of the Coastal zone, favorable conditions for groundwater recharge, cost savings due to minimized distance of distribution piping, ability to discharge brine through the existing truck sewer line, assists the SSLOCSD in meeting redundancy requirements of the Regional Water Quality Control Board, better overall feasibility of a SSLOCSD Recycled Water project and improved timing for potential water bond funding opportunities. The project is conceptual at this time, but it is generally anticipated that at 90% recovery, the project could generate approximately 500-600 acre-feet per year of water. In order to evaluate the technical and economic feasibility of the SWRRF, the SSLOCSD is engaging Water Systems Consulting (WSC) to develop the grant application and, if successful, prepare the Study. An initial investment analysis is included in the scope of work to determine economic feasibility first. If the project is deemed economically viable, WSC will proceed with development of projected water supplies and characteristics, wastewater characteristics and facilities, treatment requirements, recycled water opportunities, legal permitting requirements, and the recommended facilities project plan. ALTERNATIVES: The following alternatives are presented for the Council’s consideration:  Approve staff’s recommendations;  Do not approve staff’s recommendations;  Modify as appropriate and approve staff’s recommendations; or  Provide direction to staff. ADVANTAGES: The recommended action will allow the City of Arroyo Grande to take advantage of a grant opportunity to leverage funding, pursue a recycled water project that would benefit Item 8.c. - Page 2 CITY COUNCIL CONSIDERATION OF PARTICIPATION IN A RECYCLED WATER FACILITIES PLANNING STUDY SEPTEMBER 23, 2014 PAGE 3 the City and the SSLOCSD, and potentially position the project for additional funding opportunities in the future. The project is in line with long term water resource objectives of the City. DISADVANTAGES: Staff believes there is little disadvantage to proceeding with the study. With regard to any future project, there are a number of issues that will need to be resolved in order to proceed. These include costs, coordination and approval by partner agencies, environmental impacts, and the permitting process involved. ENVIRONMENTAL REVIEW: No environmental review is required for the study at this time. Environmental review will be required prior to proceeding with approval of any improvement project(s). PUBLIC NOTIFICATION AND COMMENTS: The Agenda was posted in front of City Hall on Thursday, September 18, 2014. The Agenda and report were posted on the City’s website on Friday, September 19, 2014. No public comments were received. Attachment: 1. Proposal from WSC, Inc. Item 8.c. - Page 3 J o·~wsc ;~ WATER SYSTEMS CONSULTING, INC. 8/12/2014 Shannon Sweeney South San Luis Obispo County Sanitation District SUBJECT: PROPOSAL TO COMPLETE A RECYCLED WATER FACILITIES PLANNING STUDY FOR A SATELLITE WATER RESOURCE RECOVERY FACILITY FOR THE SOUTH SAN LUIS OBISPO COUNTY SANITATION DISTRICT As requested, WSC has prepared the following proposal to prepare a grant application for and complete a Recycled Water Facilities Planning Study (RWFPS) for a potential Satellite Water Resources Recovery Facility (SWRRF) for the South San Luis County Sanitation District (SSLOCSD). The pu'rpose of the RWFPS will be to evaluate, identify a preferred alternative and develop an implementation plan for a SWWRF within the SSLOCSD's collection system. The SSLOCSD Wastewater Treatment Plant (WWTP) currently lacks sufficient redundancy for its secondary treatment system to allow for the existing trickling filter to be taken out of service for extended maintenance or in the event of a process upset. It is envisioned that development of a SWRRF would provide the SSLOCSD with increased upstream treatment capacity and the ability to reduce flow -rates at the existing WWTP to accommodate maintenance activities and process upsets. The SSLOCSD provides wastewater treatment services for the Cities of Arroyo Grande, Grover Beach and the Oceana Community Services District (Member Agencies). The water supplies for these agencies, specifically the Northern Cities Managemer:it Area (NCMA) of the Santa Maria Groundwater Basin, have been significantly impacted by drought conditions over the last 10 years. The development of a SWRRF would provide these agencies with access to a supplemental water supply that could be used to offset groundwater pumping or recharge the groundwat~r basin and improve water supply reliability for Southern San Luis Obispo County. In order assist the SSLOCSD in evaluating the economic feasibility and funding the development of a SWRRF, WSC proposes the following funding plan: 1. Develop an application for grant funding of $75,000 for a Recycled Water Facilities Planning Study through the State Water Resources Control Board's (SWRCB) Water Recycling Facilities Planning Grant Program (FPGP). 2. Prepare the RWFPS, including an initial investment analysis to determine if the proposed concept is economically feasible_ to implement. 3. Upon completion of the RWFPS, apply for a low interest loan through the SWRCB's Clean Water State Revolving Fund (SRF) for planning, design, and construction of the SWRRF. Funds from this PO Rox tfl)'i I s,111 I uis OIJl'.po, CA 93403 I Pho1lP: (805) 457-ll83·; I i:,1x: (80<>) ggg 276'] I 'vVWW.W~< -Ill<" COili ATTACHMENT 1 Item 8.c. - Page 4 loan could be utilized to reimburse the SSLOCSD for expenses accrued during the development of the RWFPS. This proposal does not include scope to complete the SRF funding process. To accomplish the steps described above, WSC prepared the attached scope of work, schedule and fee estimate for SSLOCSD review.
