Document Description
Improvements to the Wastewater Treatment Plant (WWTP) with addition of ultraviolet (UV) disinfection facilities for removal of fecal coliform to meet new discharge requirements for cyanide and trihalomethane (THMs), and denitrification modifications to meet more stringent nitrogen limits. The project will be constructed within the City of Grass Valley's existing WWTP. The proposed project consists of removal/decommissioning of existing chlorine gas and sulpher-dioxide disinfection equipment; installation of UV disinfection facility in an existing chlorine contact basin; a sodium hypochlorite feed system for the non-potable water system; covers on one of the secondary clarifiers; covers on the tertiary filters and other yard structures; and air piping to improve denitrification facilities.
