Site work for a water / sewer project in N Richmond, California. Completed plans call for site work for a water / sewer project.

The West County Agency (WCA) provides coordination between WCW and the City of Richmond. The treated effluent from the West County Wastewater (WCW) WQRRP flows to the confluence structure at the City of Richmond Wastewater Treatment Plant (COR WWTP). The confluence structure at the COR WWTP is where the two effluent sources are combined into the Joint Marine Outfall (Outfall) that discharges into the San Francisco Bay. An aerial exhibit showing the location of the two treatment plants, the Outfall and the approximate location of the work is included as Attachment A. Please note as shown on Attachment B the work site is approximately 31 feet under water. The Outfall was designed and constructed in 1978. Attachment B shows an overall profile of the Outfall. It consists of approximately 1,050 feet of 54inch reinforced concrete pipe (RCP) and 12,025 feet of 72-inch RCP. The Plan and Profile sheets from the original 1978 plans (1980 As-builts) are included as the Attachment C. The last 1,100 feet of the Outfall consists of 140 diffusers connected to the crown of the pipe. The diffuser section of the outfall pipeline was rehabilitated in 1993 with the replacement of the 140 diffuser ports. The Tide Flex diffuser nozzles provide a positive effluent discharge and reduce the possibility of backflow of seawater due to changes in water depth due to tidal action. The 1993 plans for the replacement of the outfall diffusers and associated anodes is included as Attachment D. Attachment E is the Outfall Diffusers Inspection Report from January 17, 2020, which details the most recent inspection results and identifies diffusers and anodes that need replacement or minor repair. This report was used to develop the current scope of work. In the event of a conflict between Attachment F and Attachment E; The quantities in Attachment E shall govern.
