Water comes from City of Seal Beach water system
The City of Seal Beach water system supplies Seal Beach: about 96% of residents live in its service area. It buys treated surface water (EPA lists Long Beach Utilities Department and Metropolitan Water Dist. of So. Cal. and Golden State Wc - West Orange County and City of Huntington Beach and City of Westminster as sellers) and serves 24,937 people in all.
No health-based violations reported to EPA in the five years to October 2026, like 83% of the 3,525 systems serving 10,001–50,000 people.
