Customers in Fresno are much happier with their water service than residents of San Diego. So are ratepayers in Sacramento, Los Angeles, Honolulu and Denver. In fact, a new survey found only one water provider in the western United States less popular than the San Diego Water Department — the San Jose Water Co., a for-profit utility whose corporate owner is publicly traded on the New York Stock Exchange. The city of San Diego ranked 23rd out of 24 large water providers in a customer-satisfaction survey published by J.D. Power, the global marketing and information services company based in Orange County.
