The Rancho California Water District (RCWD) and Eastern Municipal Water District (EMWD) have entered into a mutual agreement to swap sewer flows to allow for the decommissioning of RCWD’s Winchester Park lift station.
The current sewer flows entering the lift station will be permanently diverted at the influent manhole (MH) to the downstream gravity sewer connected to EMWD's gravity collection system. An equal amount of flow (50,000 gallons per day current to 270,000 gpd buildout) will be diverted from EMWD's gravity sewer to the Santa Rosa Water Reclamation Facility at the Adams Avenue Diversion structure.
LEE + RO’s role is to review, evaluate, and validate RCWD’s developed and selected concepts for flow control modifications and flow diversions. LEE + RO will make recommendations supporting the flow control concepts, develop flow calculations, preliminary layout, sizing, and configuration of the recommended flow control facilities.
LEE + RO’s design services are for a bid-ready set of contract documents. The documents will include plans, specifications, and cost estimates for the Winchester lift station Influent MH Modifications and the Adams Avenue Diversion Structure Modifications.
