Provider briefing
How this utility’s billing works
San Gabriel County Water District operates as a public water authority serving San Gabriel County Water District service area in Rosemead, San Gabriel, Temple City, and adjacent Los Angeles County communities; active CWS PWS CA1910144. Customers should use the provider’s current account-specific bill and official customer-service instructions as the final authority for deadlines, balances, and service requests.
The published water-rate framework is described as Bi-monthly fixed meter-capacity charge plus a uniform commodity rate per HCF, with separate pass-through Water Quality Authority, cross-connection, and fire-service charges. Effective January 1, 2026, a 5/8-inch meter capacity charge is $51.49 per bi-monthly bill and the commodity rate is $2.71 per HCF/748 gallons for all customers.. Bills are generated bi-monthly. sgcwd’s sb 998 page states that bills are issued on a bi-monthly basis and bills unpaid after 60 days are subject to shutoff., and a typical residential cost reference is Approximately $45–$58 per month water-only equivalent for a 5/8-inch residential meter using 5,000–7,000 gallons: the $51.49 bi-monthly capacity charge averages $25.75/month, while 6.68–9.36 HCF at $2.71/HCF adds about $18.10–$25.38/month, before the Water Quality Authority pass-through and any other account charges.. These descriptions are useful planning benchmarks; actual charges can change with meter size, usage, sewer averaging, local taxes, drought stages, or account-specific fees.
Wastewater and sewer calculation
SGCWD is a water district and its published bill explanation identifies water meter charge, water charge, Water Quality Assurance pass-through, and other water-account items; it does not publish a sewer/wastewater calculation. Any sewer charge is likely a separate city or sanitation-agency bill and should not be inferred from SGCWD’s water HCF charge.
Meter and infrastructure notes
The District’s bill explanation uses bi-monthly billing periods and HCF units, and its 2021 news page references high-tech meter upgrades. The reviewed current pages do not identify a universal AMI vendor or exact telemetry interval; the defensible description is bi-monthly metered service with upgraded digital/remote-read capability where installed, subject to District confirmation for the individual account.
