- California Water Service Group is a publicly traded water utility company providing water and wastewater services to over two million people primarily west of the Mississippi River in the United States. Founded in 1926 and headquartered in San Jose, California, the company operates through its five subsidiaries: California Water Service, Hawaii Water Service, New Mexico Water Service, Texas Water Service, and Washington Water Service. Its core products and services include securing, treating, testing, storing, and delivering potable water for residential, commercial, industrial, and public authority use, fire protection services, wastewater collection and treatment, recycled water provision, and non-regulated water-related services such as operating municipally and privately owned water systems, meter reading, billing services, and leasing of communication antenna sites. Recent major company developments include the acquisition agreements signed in 2025 by California Water Service, the largest subsidiary, to acquire water utility assets of Casa Loma Water Company and Palm Mutual Water Company in the Bakersfield region, subject to regulatory approval and intended system upgrades to improve fire flow and system pressure. Additionally, the company has ongoing infrastructure upgrades across various service areas including Oak Hills, Visalia, Chico, and Leona Valley aimed at enhancing water supply reliability and fire protection. Hawaii Water Service recently proposed its first rate adjustment since 2021 reflecting investments to improve reliability and maintain safety. The company also launched its annual Firefighter Grant Program supporting local first responders. California Water Service Group operates across multiple states including California, Hawaii, New Mexico, Texas, and Washington. It is recognized as the third-largest publicly traded water utility in the United States, focusing on infrastructure investment, regulatory compliance, and expansion through strategic acquisitions and system improvements. The company emphasizes environmental sustainability, water quality, and community-oriented service initiatives as central to its operational strategy.
