Document Description
The San Francisco Public Utilities Commission (SFPUC) proposes the Cross Connection Controls project to address California Department of Health Services concerns regarding potential contamination along the SFPUC's regional water system. Contamination may occur where air valves and blow-off valves, while being opened or closed, allow water from outside of the system (rainfall, flood water, etc.) to enter and compromise water quality. The proposed project would install protective devices to insure the integrity of certain identified value systems. There are 27 sites along the regional water system in Alameda, Santa Clara, and San Mateo counties where existing configurations for air/vacuum relief valves and blow-offs create potential cross-connections that must be corrected. The proposed project would include one or more of the following activities: - Reconstruct or raise an existing vault with a new cover. - Install a new vault cover with new air vents. - Install new flap valves or blank flanges on an existing blow-off pipe. - Replace an existing air vent within an existing vault. - Modify, relocate or remove an existing blow-off. - Abandon a vault and construct a new one. - Exploratory excavation to determine needed construction.
