Document Description
CLWA proposes to expand the existing Rio Vista Water Treatment Plant (RVWTP) treatment capacity from 30 million gallons per day (mgd) to 60 mgd in response to current and proposed water quality standards, and to improve reliability to meet existing customer demands and demand from planned and approved development. Additionally, the proposed project would include modifications to the Intake Pump Station (IPS) to increase the capacity to 60 mgd. As part of the project, a parallel pipeline connection to the existing 42-inch connection to the Metropolitan Water District of Southern California's (MWD) 201-inch Foothill Feeder would be constructed. This would include approximately 200 feet of 48-inch underground pipeline and an associated meter structure.
