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
- Residential accounts may be billed monthly or quarterly according to the account and meter-reading route. California American Water describes regular meter readings and says residential customers can receive monthly or quarterly bills; the statement's service dates and due date control the individual account.
- Rate structure
- The 2026 CPUC Schedule SOU-1 for the Southern Division Los Angeles Service Area covering San Marino, Duarte, and Rio Plaza uses increasing residential block rates per 100 gallons (CGL): the first 85 CGL at $0.6657, the next 50 at $0.7766, the next 163 at $0.8727, and all use over 298 CGL at $0.9844. A 5/8 x 3/4-inch residential meter has a $25.95 monthly readiness-to-serve charge; larger meters have higher charges. The bill can also include the $0.0670 per-CGL San Marino purchase-water surcharge, the $0.0024 per-CGL purchase-power surcharge, CPUC reimbursement, CAP, the 1.111% San Marino franchise fee, and other authorized tariff items.
- Residential cost reference
- For a typical 5/8 x 3/4-inch meter using 5,000–7,000 gallons per month (50–70 CGL, still within the first tier), the 2026 base calculation is approximately $59.24–$72.55 before the San Marino purchase-water and purchase-power surcharges, CAP surcharge, 1.111% franchise fee, CPUC reimbursement, taxes, and any other bill items. Including the two published quantity surcharges but excluding percentage-based and account-specific items gives an indicative $62.71–$77.41 range; the actual bill should be calculated from the current statement and all tariff schedules.
- Meter reading
- California American Water describes regular monthly or quarterly meter readings for residential accounts, with the actual schedule depending on the account and route. The company is replacing aging meters with Badger Meter AMI, which can provide detailed usage, near-real-time readings, streamlined meter reading, and possible leak notifications. Customers can request a manual-meter opt-out by calling 1-888-237-1333; the current company information states a $13 monthly opt-out charge plus a $70 initial fee. The San Marino record does not publish a conversion percentage or exact route date, so the local system should be treated as AMI-transitioning with account-specific wireless or manual reads.
- New-account deposit
- California American Water Rules 6 and 7 govern establishment or re-establishment of credit and deposits. The reviewed public San Marino pages do not state one universal 2026 startup-deposit dollar amount or a guaranteed credit-check waiver. A deposit can be required based on the applicant's credit and account circumstances and may be required after delinquency or restoration; the exact amount, payment method, and refund or application-to-bill terms must be obtained from California American Water for the specific premise.
- Activation or transfer fee
- No universal publicly stated 2026 routine activation or name-transfer fee was found for San Marino. MyWater can support turning service on or off, while California American Water tariff rules govern applications, connections, meters, deposits, construction, and special services. Any physical connection, meter, or special-service charge is separate from an ordinary account transfer and must be quoted for the address.
