Groundwater Management Program


San Francisco's Groundwater Basins

Our groundwater management program ensures that local groundwater resources designated for current or future beneficial use are properly protected to prevent overdraft, pollution or contamination. There are 7 groundwater basins in San Francisco.

North Westside Basin Groundwater Management Plan

We are preparing a Groundwater Management Plan for the North Westside Basin. The overall goal of the plan will be to assure a long-term, high quality, local water supply for current and future uses. Management of groundwater resources under a Groundwater Management Plan is essential to maintain a good quality, reliable groundwater source.

If you wish to be added to our list of interested parties, you may submit your contact information to: Carolyn Cooper, San Francisco Public Utilities Commission, Water Resources Division, 525 Golden Gate Avenue, 10th Floor, San Francisco, California, 94102 or

On January 28, 2014, the San Francisco Public Utilities Commission held a public hearing to discuss and adopt a Resolution of Intent to Prepare a Groundwater Management Plan for the North Westside Basin. A copy of the resolution can be found here.

Groundwater Monitoring and Data Management

The Westside Basin Groundwater Monitoring Program provides information summarizing basin-wide groundwater pumping, groundwater levels and quality in the different aquifer systems within the basin, and surface water conditions, most notably in Lake Merced. The program also monitors physical and chemical changes in the groundwater system resulting from current pumping at the San Francisco Zoo and Golden Gate Park, the proposed San Francisco Groundwater Supply Project wells, and the proposed Regional Groundwater Storage and Recovery Project in northern San Mateo County.

The current Annual Monitoring Report is available here.
