California Domestic Water Company

What California Domestic Water Company does

California Domestic Water Company is a not-for-profit mutual water company incorporated in 1902 (with predecessor origins dating to 1889), headquartered in Whittier, California. The company operates as a wholesale water provider, extracting and treating groundwater from the Main San Gabriel Basin through seven active wells and a 30-mile transmission pipeline that crosses Los Angeles and Orange Counties, ultimately delivering 20,000-25,000 acre-feet of potable water annually to three primary shareholders: City of La Habra, City of Brea, and Suburban Water Systems, collectively serving approximately 222,000 people in Whittier, La Mirada, La Habra, and Brea.

The company's core technology is its groundwater extraction, treatment, and transmission system. Water is processed through three primary treatment facilities — an air stripper (constructed 1986) for removal of industrial solvents and VOCs, an ion exchange facility (constructed 2000-2002 and expanded 2018-2023) for PFAS, perchlorate, and NDMA, and a UV light facility (2000-2002) — alongside high-efficiency pumping plants and a 5-million-gallon storage reservoir (Bassett, 1999). The company conducts over 2,000 water quality samples annually to ensure compliance with federal Safe Drinking Water Act standards. The capital-intensive infrastructure includes approximately 30 miles of transmission pipeline, with a near-term $12 million priority replacement of the 48-inch M-Line funded through shareholder capital.

Cal Domestic generates revenue primarily through wholesale water sales to its three primary shareholders, with rates established annually by the Board of Directors. Water deliveries are governed by stock entitlements allocated under the 1973 Main San Gabriel Basin adjudication overseen by the Watermaster Board. A retail service segment serving approximately 160 remaining residential shareholders is being actively transitioned to municipal providers. Capital is raised through common stock issuances to shareholders — most recently a 2022-2023 issuance generating $5,718,750 — supplemented by federal grants (e.g., $2.6M from the San Gabriel Basin Water Quality Authority for PFAS treatment). The company also benefits from the Baldwin Park Operable Unit Superfund settlement, which reimburses 100% of treatment O&M costs from 2001-2027. Ownership is mutual, with the three primary shareholders holding the majority of common stock; the wholly-owned subsidiary Cadway, Inc. manages related real estate.
