Billing and account research from public material
Provider-specific research notes are displayed separately from fields that contain only an unavailable-information marker. Read qualifiers in each note and verify current account terms with the provider.
- Billing frequency
- 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.
- Rate structure
- 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.
- Residential cost reference
- 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.
- 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 reading
- 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.
- New-account deposit
- A meter deposit of $50 or more, depending on meter size, is required before new service can be established. Under the municipal code, an applicant may avoid the security deposit by establishing credit; one year of prompt monthly payment without nonpayment discontinuance is presumed to establish credit, and an owner who has paid promptly for at least one year may request return of the deposit. Other deposits are returned when the account closes after unpaid bills are deducted, subject to receipt and code rules.
- Activation or transfer fee
- The City does not publish a universal 2026 water activation or account-transfer fee in the reviewed start-service materials. New service or cancellation requires a completed Utility Request Form, service address, identity, proof of ownership or tenancy, and the meter deposit; partial applications are rejected. New services and cancellations take one business day to process, and City Hall is closed Fridays, weekends, and holidays. Call (626) 307-1342 or email utilitypayments@montereypark.ca.gov for any connection, transfer, field, or special inspection charge.
