Document Description
PROJECT NUMBER: 4410010-003C
The State Water Resources Control Board (State Water Board) is a Responsible Agency for the Project. The State Water Board is funding the Project referred to internally as Graham Hill Water Treatment Plant Facility Improvements Project. The Project would replace and substantially upgrade the majority of the existing water treatment processes at the Graham Hill Water Treatment Plant (GHWTP) and associated infrastructure. The Project would include solids dewatering to allow for more efficient separation and disposal of solids that are removed from the raw water during the treatment process. Upgrades to the chemical feed systems would also be included as well as a replacement wash water supply tank, a new ozone contactor, pre-treatment processes, granular activated carbon contactors, and recycled water clarifiers.
The Project includes demolition of the operation and filter building, water treatment facilities (e.g., sedimentation basins), and infrastructure, as needed to address facilities beyond their useful life or to accommodate new facilities.
Also, the Project involves new and upgraded buildings including a new administration building and/or operations building, new maintenance building, heating, ventilation and air conditioning (HVAC) improvements, replacement or upgrade of the filter gallery building, and new ozone, solids dewatering, and chemical storage facilities. These activities would occur on the GHWTP parcel.
The Project includes infrastructure and site improvements including piping and storm water management improvements; electrical, and Supervisory Control and Data Acquisition (SCADA) improvements; vehicular access improvements; landscaping improvements; and may include fencing and site security. These activities would occur within the utility corridor, Graham Hill Road right-of-way and the alternate sanitary sewer lateral improvement area.
