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
- Periodic municipal utility-services statements; the ordinance makes water, sewerage, refuse, sanitation, and related charges payable on the statement due date. The retrieved current public material does not state one universal monthly or bi-monthly schedule for every Santa Ana water account, so customers should follow the billing interval printed on the statement.
- Rate structure
- Metered volumetric water pricing with a water commodity charge, Water Commodity Adjustment, Water System Reliability Adjustment, and fixed water-service components established by City resolution. The 2026 rate notice identifies a proposed/current total commodity charge of $4.11 per HCF, composed of $0.15 WCA, $2.71 commodity charge, and $1.25 WSRA. Actual bill amounts also depend on meter size, service charges, and the City’s other municipal utility line items.
- Residential cost reference
- A precise 5,000–7,000-gallon estimate requires the customer’s meter size and the current Santa Ana fixed-charge schedule. At approximately 6.7–9.4 HCF, the published 2026 total commodity charge of $4.11/HCF implies roughly $27–$39 in usage charges before fixed water, sewer, refuse, sanitation, and other municipal charges. The public pages retrieved do not publish one universal average residential total; customers should use the City’s current statement and rate study for the combined water-and-sewer amount.
- Wastewater and sewer calculation
- Santa Ana’s municipal code states that sewerage service charges are listed separately on the same utility statement and are based on the volume of water entering the City sewer system as measured by metered water service. The public code does not describe a winter-average calculation or a universal flat percentage tie-in; sewer, refuse, sanitation, water, penalties, and fees are separate line items but share the statement’s payment and penalty rules.
- Meter reading
- Santa Ana’s MyWater portal exposes smart-meter consumption data, downloadable water-use analysis, and transaction history. The active CWS has approximately 40,025 residential meters, and the City’s ordinance provides monthly/periodic meter-read, reread, and seasonally adjusted estimation rules when a meter cannot register accurately. The public portal does not identify the AMI vendor or guarantee an hourly transmission interval, but customers can use the portal to review available account-specific smart-meter data.
- Activation or transfer fee
- The ordinance authorizes meter turn-on, meter-read-trip, meter-reset, and other field fees for new service, transfer of responsibility, or restoration, but the retrieved public text delegates dollar amounts to City Council resolutions. Santa Ana’s MyWater portal and City account channels support service-account management; customers should confirm the current ordinary activation or transfer charge and any same-day/after-hours premium before submitting a request.
