Disinfection Chemical Storage Project

The disinfection conversion project – known as the Disinfection Chemical Storage (DCS) is a $15 million project that included the construction of a new facility within the main plant fence.  It included a new Operations Building, fiberglass storage tank farm, unloading, transfer, and metering pumping, and distribution and injection of hypochlorite to the primary influent, primary effluent, and secondary effluent channels.  The other feature of the project included an expansion of the existing sodium bisulfate dechlorination system at the treatment plant’s outfall facility adjacent to the Sacramento River.  This included adding three new fiberglass storage tanks, unloading and metering pumps to inject the bisulfate where it dechlorinates the final effluent stream prior to discharging into the river.
