Cal Water will begin work on a water infrastructure upgrade next month that will enhance water supply reliability and fire protection in South San Francisco. Cal Water crews will install nearly 1,000 feet of new water main just south of San Bruno Mountain, which is prone to wildfires.
“Infrastructure improvements like these are crucial. Not only do they help us continue to deliver a reliable source of water for everyday needs, but they also allow us to keep supporting our firefighters as they protect our communities,” said Ross Moilan, Bayshore District Manager. “For Cal Water, it’s all about providing quality, service, and value to the communities we serve.”
The project is expected to take three months, beginning in August and culminating by the end of November. Work will take place south of Mills Montessori School, Monday through Friday from 7 a.m. to 5 p.m. Construction will begin near the intersection of Ridgeview Court and La Montagne Place, continue through the apartment complex nearby, then toward the intersection of Hemlock Avenue and Lincoln Street, and continue north until reaching Hillside Boulevard. Crews will work to minimize impact to traffic and will notify customers when there are any traffic disruptions. Temporary asphalt will be applied until permanent paving is completed, which can be up to 30 days after project completion.
