Water Supply Master Plan and Recycled Water Program Cost Analysis
City of Sacramento, California

West Yost led the City and associated stakeholders through an evaluation and cost analysis of a potential recycled water program for the City. This evaluation provided the City with information to make an informed decision on whether to proceed with the Recycled Water Program. The analysis involved a recycled water program cost estimate; a no-project cost estimate; a discussion about options for participation, such as the pros and cons of the City becoming a recycled water purveyor; a summary of recycled water project funding opportunities; and a discussion about the City’s water rates and ratepayer’s willingness to pay.

West Yost completed a comprehensive Water Supply Master Plan (WSMP) Update for the City. This plan presented a reliable and flexible water supply strategy for using surface and groundwater sources to meet the future demands, and recommended a capital improvement program (CIP) to guide the City’s immediate and long-term investments. The Plan recommended future groundwater projects that should be implemented to improve the existing pumping capacity reliability and to develop a citywide conjunctive use supply portfolio. 

West Yost evaluated alternative water supplies that included the conjunctive use of groundwater and surface water supplies, recycled water, conservation, and greywater to meet the future needs in a sustainable manner. The plan included a reliable and flexible water supply strategy using surface and groundwater sources to meet the future demands, and included a recommended CIP to guide the City’s immediate and long-term investments. Our team performed the analysis using a GIS-based approach to develop water use projections tailored to detailed land use planning categories established by the City. The supply analysis evaluated further integration of groundwater and surface water supplies for the City. West Yost also assessed the feasibility and impacts of using reclaimed water to meet non-potable demands and used the City’s GIS system to assist in identifying where recycled water is the most economically feasible.
