H2O America

H2O America, operating nationwide via its various subsidiaries, is a key provider of essential water utility and associated services.

The company manages the entire water lifecycle, from procuring, storing, and purifying water to its distribution, wholesale, and retail sale, alongside offering wastewater management services.

Its water supply is diverse, sourced from groundwater wells, surface water collected through watershed runoff and diversions, reclaimed water, and imported water acquired from the Santa Clara Valley Water District. Beyond its primary utility offerings, H2O America also delivers a suite of non-regulated services. These include the management and maintenance of water systems, various contracted services, leasing opportunities for antenna sites, and other water and sewer operational services. A notable offering is the "Linebacker protection plan," specifically tailored for its public drinking water clients in Connecticut and Maine.

The company's extensive service footprint spans several regions. In California, it supplies water to approximately 232,000 connections, benefiting about one million residents in portions of San Jose and Cupertino, as well as the cities of Campbell, Monte Sereno, Saratoga, the Town of Los Gatos, and surrounding unincorporated areas of Santa Clara County. In Connecticut and Maine, H2O America serves roughly 142,000 connections, providing water to an estimated 463,000 individuals across 81 municipalities within an approximate 275-square-mile service area.

Additionally, it oversees around 3,000 wastewater connections in Southbury, Connecticut. Further south, in the corridor between San Antonio and Austin, Texas, the company services approximately 29,000 water connections for about 88,000 people across an area exceeding 271 square miles, supplemented by approximately 1,000 wastewater connections. H2O America also holds various real estate assets, including undeveloped land in California and both commercial properties and land parcels situated in Connecticut.

The company, which was incorporated in 1985 and is headquartered in San Jose, California, was previously known as SJW Group before officially rebranding to H2O America in May 2025.
