SAN JOSE, Calif.—(NYSE: CWT)—California Water Service (Cal Water) has been ranked highest in overall customer satisfaction among large water utilities in the western United States, in the J.D. Power 2023 Water Utility Residential Customer Satisfaction StudySM. The results, which recognize the top-ranking large utility and midsize utility in four U.S. regions, were based on survey responses collected from residential water utility customers in four waves from June 2022 through March 2023.
