Provider briefing

How this utility’s billing works

Suburban Water Systems - La Mirada System (Whittier/La Mirada Service Area) operates as a private investor-owned utility serving Whittier/La Mirada service area: portions of Whittier, La Mirada, Buena Park, La Habra, Compton, Willowbrook, and adjacent Los Angeles and Orange County areas. 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 CPUC-regulated two-block metered residential pricing, with service charge by meter size plus quantity charges that vary by Whittier/La Mirada tariff area. The current Schedule WLM-1 lists 2026-applicable base rates of $3.864/$4.361 per CCF in Area 1, $4.106/$4.527 in Area 2, and $4.438/$4.815 in Area 3, with the block-1 breakpoint at 20 CCF and a 5/8 x 3/4-inch service charge of $16.55 per month. Bills also carry applicable CPUC fees, water-offset charges, CAP surcharges or surcredits, and a City of Whittier local-government fee where applicable.. Bills are generated monthly billing. the bill shows the billing date, past-due-after date, meter readings, ccf usage, service charge, water charge, applicable offsets, cpuc or local charges, and total current amount due. suburban states that one ccf equals 100 cubic feet, approximately 748 gallons, and fractions of a ccf are not charged., and a typical residential cost reference is Approximately $42-$55 for 5,000 gallons and $62-$75 for 7,000 gallons before city taxes, CPUC fees, water-offset charges, CAP surcharges, and other line items, using 6.684 and 9.358 CCF respectively, the $16.55 5/8 x 3/4-inch service charge, and the published 2026 Whittier/La Mirada tariff-area ranges. Exact cost depends on the tariff area, local tax, and approved temporary adjustments.. 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

Suburban Water Systems' bill can include water and, in some service areas, wastewater-related charges, but the WLM-1 potable-water tariff prices metered water by CCF. Where sewer is provided by Whittier, La Mirada, Buena Park, La Habra, a sanitation district, or another agency, that agency may bill a separate fixed, winter-average, or water-use-based charge. Customers should identify the sewer line item and ask the serving agency for its current base, winter average, cap, and adjustment formula rather than assuming a fixed percentage of the Suburban water charge.

Meter and infrastructure notes

Suburban bills from customer meter readings and reports the current and prior readings and CCF usage on the bill. The reviewed La Mirada system materials do not publish a uniform AMI deployment percentage or fixed route calendar; customers should use the bill's read dates, My Account usage history, and any alerts, and ask Suburban to confirm the exact meter technology and leak-monitoring capability for the premise. The SDWIS record lists active groundwater wells and multiple interconnections with metropolitan, city, and neighboring Suburban systems.
