City of Monterey Park Water Utility Division

Provider briefing

How this utility’s billing works

City of Monterey Park Water Utility Division operates as a municipal department serving City of Monterey Park municipal water service area, Los Angeles County; active CWS PWS CA1910092. 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 Monthly metered increasing-block residential water rates with a fixed meter service charge; single-family residential customers have three consumption tiers and other customers use a uniform consumption rate. The FY 2026–27 rate-study schedule effective July 1, 2026 lists SFR Tier 1 at 0–10 HCF, Tier 2 at 11–16 HCF, and Tier 3 at 17+ HCF, with charges of $4.26, $5.61, and $10.62 per HCF in the bond-funded schedule. The 5/8-inch monthly service charge is $25.16. One HCF equals 748 gallons. Sewer is separately billed, generally as a fixed account or dwelling-unit charge in the published bill-impact schedule.. Bills are generated monthly. the city recently transitioned from bi-monthly to monthly utility billing. monthly bills are due when rendered; the municipal code treats amounts unpaid 30 days after the billing date as delinquent, and the city code permits discontinuation after 60 days from the billing date when payment or an approved financial-need arrangement has not been received., and a typical residential cost reference is Approximately $54–$65 per month for water only for a 5/8-inch residential meter using 5,000–7,000 gallons (about 6.68–9.36 HCF), using the FY 2026–27 bond-funded schedule: $25.16 monthly fixed charge plus Tier 1 usage at $4.26/HCF. The City's published 3/4-inch 10-HCF example is $76.55 water and $24.71 sewer, or $101.25 combined monthly in FY 2026–27; the 5/8-inch estimate is not a sewer-inclusive bill quote and the actual account tier, meter, sewer charge, and adopted 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

Monterey Park bills sewer separately from water on the utility account. The FY 2026–27 City rate-study bill-impact table shows a $24.71 monthly sewer charge per account for the representative single-family example and $247.09 for a representative 10-unit multifamily account; the public material does not describe a winter-average or water-intake-percentage formula for ordinary residential accounts. Treat the sewer amount as a separate municipal charge, not part of the water consumption calculation.

Meter and infrastructure notes

The City operates approximately 13,400 water meters and lists meter readings, meter replacements and upgrades, pumping, flushing, and emergency repairs among Water Utility Division duties. The official pages do not identify a universal AMI/AMR vendor, hourly transmission, or route schedule; the defensible description is regular municipal meter reading with monthly billing and active replacement/upgrade work. Customers can request meter assistance through (626) 307-1342 and should not assume smart-meter leak alerts without premise confirmation.
