California Water Service Main Replacement Project Will Improve Water Supply Reliability in Chico

CHICO, Calif. — California Water Service (Cal Water) is completing a water main replacement project in the city of Chico that includes the addition of nearly 1,500 feet of new water main. The new main will increase the flow of water, eliminate leaks, enhance fire protection, and improve the overall water supply reliability in the downtown Chico area.

The older 6-inch, cast iron main was replaced with an 8-inch PVC pipe. Once the project is completed, which is expected by the beginning of March, residents on Olive Street and East 6th and 5th Streets will also have had their service lines replaced, and their meter boxes replaced, if needed.

"This project is part of a larger, proactive plan to replace aging and less reliable water main in the Chico District to improve the dependability of our system. It's part of our commitment to provide our customers and communities with quality, service, and value," said District Manager Pete Bonacich. "One of the many benefits of the project is that the new main will allow more water to flow to the area to better support important fire-fighting capabilities."

Cal Water serves about 104,000 people through 29,000 service connections in Chico and Hamilton City. The company, which has provided water service in the area since 1926, 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
