San Carlos Main Replacement Project to Ensure Future Reliability to Customers

SAN MATEO, Calif.—California Water Service Company (Cal Water) announced today that it would be starting an infrastructure improvement project in the city of San Carlos on Jan. 5, 2015, with the installation of 1,900 feet of water main.

The original four- and six-inch cast-iron main will be replaced with 6-inch ductile iron water main to increase flow and improve water quality and reliability through the water distribution system. The existing water mains were starting to leak and were in declining condition due to their age and the limited materials that were available when the pipeline was originally built.

The aging main will be replaced on Hillcrest Road, beginning at the intersection of Ensenada Road and continuing south to Valley Road. Construction will then continue down Valley Road, concluding at Hull Drive. The work will be done between 9 a.m. and 4 p.m. Mondays through Fridays, and detours will be established and residents may experience minor traffic delays. The project is expected to be completed in late February.

"We will do our best to minimize traffic impacts and repave the trench and ensure the streets are left in good condition when the project is complete," said Cal Water District Manager Tony Carrasco. "This project will benefit the surrounding community for years to come, as it will improve water supply reliability and quality and also increase fire protection capabilities for Cal Water customers."

Cal Water serves about 187,600 people through 53,200 service connections in San Mateo, San Carlos, and South San Francisco. The company has provided water service in the area since 1931. Additional information may be obtained online at
