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 current SB 998 policy states that bills are rendered monthly unless a rate schedule provides otherwise, are due upon presentation, and become overdue and subject to discontinuation if unpaid within 60 days of the bill date. The owner service application says current utility bills are due by the 20th of the month billed, so the printed bill date and due date control for a particular account.
- Rate structure
- Metered monthly service with a fixed readiness-to-serve meter-base charge, a dwelling-unit charge, and a volumetric water rate by billing classification. The FY 2026–27 schedule effective July 1, 2026 lists residential 1–5-unit usage at $2.58, residential 6–25 units at $3.63, and residential 26+ units at $4.48, with commercial/industrial/all multifamily rates of $3.63 or $4.48. The 5/8-inch meter-base rate is $41.02 monthly and the dwelling-unit charge is $16.45; verify whether the account's classification and actual service units place it in the appropriate row.
- Residential cost reference
- Approximately $81–$91 per month for a 5/8-inch residential account with one dwelling unit and 5,000–7,000 gallons, using the July 1, 2026–June 30, 2027 schedule's $41.02 meter-base charge, $16.45 dwelling-unit charge, and the $3.63 residential 6–25-unit volumetric row for roughly 6.68–9.36 HCF (748 gallons per HCF). This is an estimate before any taxes, penalties, special charges, or classification differences; the customer's actual rate row and bill control.
- Wastewater and sewer calculation
- South Montebello Irrigation District's public rate schedule and SB 998 policy cover potable water only and do not publish a sewer or wastewater charge, winter average, sewer cap, or percentage tie-in. A separate sanitation or municipal provider may bill wastewater. Do not add sewer to the SMID water estimate unless a separate account or assessment applies.
- Meter reading
- The District's current materials do not identify an AMI/AMR vendor, hourly transmission, or smart-meter customer portal telemetry. A current District water-worker description identifies meter reading as an operating duty, and the SB 998 policy treats meters and monthly bills as the source of the current and prior readings. The documented method is periodic field meter reading with monthly billing; confirm any premise-specific remote-read or leak-alert capability with the District.
- New-account deposit
- The owner water-service application requires proof of ownership or lease, California identification, and a non-refundable $25 opening fee included on the first month's water bill. The public application does not state a universal refundable startup deposit, but the SB 998 restoration policy can require a security deposit after nonpayment shutoff. The owner remains ultimately responsible for charges and liens, and the District may require account-specific security or other amounts before turning on service.
- Activation or transfer fee
- The owner application identifies a $25 non-refundable opening fee included with the first month's water bill. Start-service applicants email the completed owner or tenant application, proof of ownership or lease, and California driver's license or ID to smidwater@pacbell.net; District staff call within 24 business hours Monday–Friday, 8:00 a.m.–4:30 p.m. The form supports new owner, closing bill, change of name/address, and transfer-to-tenant requests. Any additional field, meter, security, or transfer charge is account-specific and not published as a universal 2026 fee.
