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. SGV Water's CPUC-regulated residential policy says bills are rendered monthly, are due upon presentation, and become past due 19 days after the mailing date. Route meter reads generally occur every 27–33 days, so the actual period and due date for Montebello 1 are the dates printed on the individual statement.
- Rate structure
- CPUC-regulated metered service using a fixed readiness-to-serve charge by meter size, a volumetric charge measured in CCF, and approved regulatory adjustments, conservation items, and surcharges or surcredits. One CCF equals 748 gallons. Montebello 1 is identified in the drinking-water registry as primarily purchased groundwater, with active wells and connections from California Water Service East Los Angeles, the City of Montebello, South Montebello Irrigation District, SGV Montebello 2, and SGV Water's Montebello interconnection. Exact Montebello 1 2026 tariff values were not text-exposed in the reviewed current rate PDF and are therefore not inferred.
- Wastewater and sewer calculation
- SGV Water Company provides potable water service only and does not bill sewer or wastewater for Montebello 1. Any wastewater charge, winter-average computation, residential cap, fixed sewer assessment, or usage percentage is administered by the separate municipal or sanitation provider serving the premise. Customers should not assume that a sewer charge is embedded in the SGV Water CCF bill.
- Meter reading
- SGV Water meters are typically read every 27–33 days and billed in CCF, with one CCF equal to 748 gallons. The registry lists active Montebello 1 wells and interconnections, but the current customer materials do not identify a universal AMI/AMR vendor, hourly radio transmission, or customer-facing smart-meter schedule. The defensible description is periodic route meter reading with account-history review and customer-service confirmation required for any advanced meter, leak-alert, or remote-read capability.
- New-account deposit
- SGV Water may require a deposit to establish or re-establish credit, but the reviewed 2026 customer pages do not state one universal Montebello 1 residential amount. The requirement depends on account history, credit status, premise, meter, and applicable CPUC rules. Applicants should provide government identification and proof of ownership or tenancy and ask the El Monte office whether a credit check waives the deposit, how the deposit is calculated, and when it is refunded or credited after satisfactory payment history.
- Activation or transfer fee
- A residential or business service application should be submitted at least 24 hours before the requested regular-business-day start or transfer date. Same-day service may be available when the request is completed before noon, and same-day restoration may require all charges to be paid before the office cutoff. SGV Water's reviewed public pages do not publish one universal Montebello 1 activation or transfer fee; connection, meter, deposit, field, credit, and same-day service charges must be confirmed for the individual premise at (626) 448-6183.
