California Water Service Begins Storage Tank Improvement Project in Rancho Palos Verdes

TORRANCE, Calif. — California Water Service (Cal Water) is making significant improvements to a 9.5-million-gallon water storage tank that serves Ranchos Palos Verdes residents and businesses. The project will extend the lifespan of the tank and improve the water supply reliability of the system.

The concrete storage tank, built in the 1970s, is the largest owned by Cal Water. It is configured in a unique "hopper bottom" style, or an upside-down pyramid without the tip, which will require a multi-stage approach to make the needed improvements. Specialty equipment will first be used to identify improvement areas, which will be followed by the development of an engineered solution.  After water in the tank has moved into the distribution system, the crew can enter and begin work.

 "This storage tank is a major part of this community because it has such a large storage capacity," said District Manager Dan Armendariz. "Our crew has come up with unique ways to tackle the construction upgrades to ensure we continue to deliver a reliable supply of high-quality water to our customers."

The water system improvement project is expected to be completed by the end of April.

Cal Water serves approximately 92,000 service connections in the Rancho Dominguez District and about 2 million people through 480,300 service connections in California. The company, which has provided water service in the area since 1927, 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 www.calwater.com.
