San Francisco Groundwater Supply Project

San Francisco Groundwater Supply Project

The San Francisco Public Utilities Commission (SFPUC) is proposing the San Francisco Groundwater Supply Project, which would provide an average of four million gallons per day (mgd) of groundwater to San Francisco's municipal water supply. Groundwater would be blended with San Francisco's existing municipal water supply for distribution within San Francisco. The project consists of the construction and operation of six potable groundwater well facilities - two that would be converted from existing irrigation well facilities and four that would be newly constructed. Nine locations are currently under consideration for potable groundwater well facilities; however, only six facilities would be constructed. Each facility would include a groundwater production well and a pump station. The SFPUC would also construct a distribution system (including pipelines and connection points) that would connect five of the well facilities to Sunset Reservoir; the sixth well would connect to the existing Lake Merced Pump Station, and would require a short length of distribution piping to make this connection. The groundwater would be pumped from the North Westside Groundwater Basin, which is located withing the larger Westside Groundwater Basin that underlies parts of the San Francisco and San Mateo Counties.
