Regional Groundwater Storage and Recovery (GSR) Project to Begin Well Drilling on June 18

On Thurs., June 18, the San Francisco Public Utilities Commission (SFPUC) Groundwater Storage and Recovery project will begin drilling a new groundwater well to a depth of 750 feet deep at Benjamin Franklin Intermediate School in Daly City. Once well drilling begins, work will occur continuously for 24-hours a day for up to a month.

To minimize noise impacts, the contractor will monitor... noise levels and install sound blankets to ensure it does not exceed the local noise ordinance. During night work, the contractor will rotate construction lighting to direct it away from homes near well drilling work.

What is the GSR Project? The SFPUC is working with Peninsula partners to diversify the region's water supply. SFPUC will store up to 20 billion gallons of groundwater in wet years to use it in future dry years. The SFPUC will drill 16 new recovery wells, stations, pumps and pipelines in order to connect to the Hetch Hetchy Regional Water System.

The GSR Project is part of the SFPUC's Water System Improvement Program. The $4.8 billion program consists of more than 80 projects to repair, replace, and seismically upgrade the aging Hetch Hetchy Regional Water System that serves 2.6 million people in San Mateo, San Francisco, Alameda, and Santa Clara counties.
