California Water Service Increases Water Supply Reliability with Two New Storage Tanks in San Carlos

SAN CARLOS, Calif. — California Water Service (Cal Water) will break ground on an infrastructure improvement project in the city of San Carlos that will add two new seismically designed, steel water storage tanks to the water system. The new tanks will improve water supply reliability during both normal conditions and during an emergency, as earthquakes and settlement are both concerns in the area. The project is slated to start next week.

One tank will be constructed at a station on Crestview Drive and the other at a station a few blocks away on Los Vientos Way. Cal Water worked with the city to ensure that the new 400,000-gallon tanks also blend in aesthetically with the neighborhood. The project is expected to be completed by December.

"This project is vital to improve the safety and reliability of the system," said Interim District Manager Mike Utz. "With additional storage capability, our crew will be better equipped to provide water to our customers in San Carlos during normal conditions, as well as during emergencies or natural disasters."

Cal Water serves approximately 53,500 service connections in San Carlos, San Mateo, and South San Francisco and about 2 million people through 480,300 service connections in California. The company, which has provided water service in the area since 1931, was ranked "Highest in Customer Satisfaction among Water Utilities in the West" in 2016 by J.D. Power in its inaugural Water Utility Residential Customer Satisfaction Study. Additional information may be obtained online at
