On August 23, 2021, San Francisco Public Utilities Commission (SFPUC) crews were fixing a leaking air valve on a 54-inch pipeline when the air valve casing failed. Water spewed into air and into adjacent areas, including Sigmund Stern Grove.
The SFPUC deployed several emergency contracts to clear debris, remove hazard trees, dry out and restore any damaged structures, and stabilize the hillside beneath the break.
The SFPUC is working closely with the San Francisco Recreation and Parks Department as well as the Stern Grove Festival Association on the repairs.
