California Water Service Begins Water Main Installation Project in King City

Project Will Improve Water Quality and Reliability for Customers

KING CITY, Calif. — A California Water Service (Cal Water) project in King City is underway to install almost 2,500 feet of large-diameter water main and connect the southwest portion of the water system to the northeast portion. The water system improvement project will improve water quality and reliability of the system.

This project, in conjunction with other main installations recently completed, will enable Cal Water to bring water from wells in the southwestern part of the city, where natural water quality is better, to the northeastern part. Construction is expected to be completed by mid-April and will include:

  • Installation of 2,496 feet of new 16-inch diameter ductile iron pipeline to replace the existing 8-inch concrete pipeline along Ellis Street
  • Connection of the existing pipelines that run across Ellis Street to the new main
  • Replacement of service lines and meter boxes for all customers on Ellis Street

"Our team is excited about this water system upgrade in particular because we've been working in close partnership with the city to improve Ellis Street," said District Manager Steve Vasquez. "At the end of the project, not only will we be better equipped to meet increased demand with a reliable supply of high-quality water, but the residents will also benefit from a repaired and cleaner Ellis Street."

Following the city's sewer line project in the summer of 2016, Cal Water agreed to reattach and seal the road after the completion of the transmission line project.

Cal Water serves approximately 2,600 service connections in King City and about 2 million people through 480,300 service connections in California. The company, which has provided water service in the area since 1962, 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
