Provider briefing
How this utility’s billing works
Los Angeles Department of Water and Power (LADWP) – Water System operates as a municipal department serving Los Angeles and the Los Angeles Department of Water and Power water-service territory, including certain Eastern Sierra service communities. 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 Seasonal, tiered metered water rates measured in hundred cubic feet (HCF), with Schedule A residential tier allotments and pass-through adjustment factors that vary by month and temperature zone. For 2026, LADWP publishes Schedule A total consumption charges for service inside Los Angeles of $12.495/$14.681/$15.427/$17.522 per HCF for Tiers 1–4 in January–June and $11.794/$14.278/$15.024/$15.024 in July–December. The posted amounts include base rates and current water-supply, water-quality, revenue-target, infrastructure, and other adjustment factors; service outside the City of Los Angeles adds the 2026 outside-city surcharge of $0.319 per HCF. The water bill is combined with separate sanitation charges administered for the City’s Bureau of Sanitation.. Bills are generated bi-monthly for residential and multi-residential water customers; the first bill for a new customer may cover more or less than 60 days. commercial service is billed monthly. ladwp also offers a voluntary level pay monthly budgeting arrangement, which does not change the underlying regular billing cycle., and a typical residential cost reference is Approximately $60–$110 per month for combined water and residential sewer service at 5,000–7,000 gallons, treated as a planning estimate rather than a universal quote. LADWP bills water every two months in HCF and applies seasonal tiers; the City’s residential Sewer Service Charge is calculated from the prior rainy-season winter-water-use estimate and is relatively stable across the following six billing periods. Trash, low-income sewer surcharges, service fees, meter conditions, temperature-zone allotments, and the actual winter average can move the total materially, so the current bill and LADWP rate schedule control.. 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
LADWP provides billing for the City of Los Angeles Bureau of Sanitation’s Sewer Service Charge (SSC). Residential sewage volume uses the Winter Water Use method: for the July 1–June 30 service year, the City calculates an average daily sewage volume from the lowest average daily water use during the preceding rainy-season review period, generally October/November through April/May. The resulting SSC is billed throughout the next six bi-monthly periods and is not tied directly to each current billing period’s water consumption. A Dry Winter Compensation Factor of 1.0 or less may be applied based on rainfall and consumption. Residential customers can request a BOS adjustment, including for qualifying pool-fill or other abnormal winter use; a private tributary/non-tributary sub-meter can replace the estimate at customer expense.
Meter and infrastructure notes
LADWP bills residential customers on a bi-monthly meter-reading cycle and measures water in HCF, with the field system able to estimate usage when a reading is inconsistent with historical use, the meter is inaccessible, or the meter is defective. Standard water meters may have direct-reading or round-dial registers; the customer can inspect the register and analyze usage through My Account. LADWP is modernizing metering and has AMI projects, but the current public water pages do not claim that every residential water meter is already a fully deployed two-way AMI endpoint. The current 2026 record is therefore mixed conventional/remote-read infrastructure, with automated or field reads and estimated bills when necessary; optional Flume monitors provide minute-by-minute customer usage data but are not the LADWP billing meter.
