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
- Regular water and sewer bills are generally monthly, although the municipal code permits billing at regular intervals as infrequently as bimonthly. The City posts same-business-day payment credit for online, drop-box, and other payments received before the applicable cutoff; customers should rely on the due date shown on the individual bill.
- Rate structure
- Tiered water-budget pricing plus a fixed Ready to Serve charge. Effective January 1, 2026, residential potable consumption is $2.13 per unit for Tier 1 efficient indoor use, $3.60 for Tier 2 efficient outdoor use, $4.77 for Tier 3 usage 1%–50% over the assigned water budget, and $5.69 for Tier 4 usage 51% or more over budget. The 5/8-inch potable Ready to Serve charge is $35.75 per month. A single-family indoor budget defaults to four residents at 47 gallons per person per day, or 188 gallons per day, while the outdoor budget uses irrigated-landscape area; residents can request a variance for household size, a repaired leak, or a filled pool.
- Residential cost reference
- Approximately $100–$106 per month for water plus the standard residential sewer charge for a 5,000–7,000-gallon household, before trash, EMS, taxes, or unusual budget overages. At 6.7–9.4 units, water is about $50.03–$55.77 when usage remains in the $2.13 Tier 1 range, consisting of the $35.75 5/8-inch Ready to Serve charge plus commodity use; the 2026 residential sewer fixed charge is $50.01 per dwelling. Actual water cost depends on the assigned indoor/outdoor budget, season, meter size, and whether use enters Tiers 2–4.
- Wastewater and sewer calculation
- Corona bills sewer service with a $50.01 monthly residential fixed charge per dwelling effective January 1, 2026. The fixed charge includes an 8-unit monthly allowance for all customers; non-residential customers pay a $6.05 variable charge for water used above 8 units in a billing period. The City’s bill explanation says sewer charges are generally based on residential units served or meter size rather than a winter-average clean-water formula. Sewer and water may appear on the same consolidated bill, but the wastewater charge is set by the separate sewer schedule.
- Meter reading
- Corona is upgrading water meters citywide to smart AMI meters. The City says the upgrade will provide hourly water-use data, leak alerts, and improved billing through MyAccount.CoronaCA.gov; the customer usage portal is identified with WaterSmart branding. During deployment, meters still need to be accessible for billing reads and the portal may show historical or newly transmitted usage depending on installation status. Customers should use the portal’s hourly data and leak alerts, compare them with the monthly bill, and call Customer Care when a read appears inconsistent or a leak alert persists.
- New-account deposit
- Corona’s public start-service page identifies a $26 new-account setup fee but does not state a universal residential startup-deposit amount. Under the municipal code, service re-establishment after a delinquency requires a cash deposit equal to three times the average monthly bill, and the City can require deposits or other security under its credit and service rules. The exact initial residential deposit, if requested for a particular applicant, is account-specific and should be confirmed with Customer Care at (951) 736-2321; the City’s public pages do not describe a credit-check waiver or standard deposit-return period.
- Activation or transfer fee
- A $26 new-account setup fee is charged on the first utility bill for all new water accounts, covering account records, a meter read, and/or turning the service on. After-hours activation, or activation requested within two hours of closing, adds $116. Start, stop, and transfer service can be requested by phone at (951) 736-2321, email to CustomerCare@CoronaCA.gov, or in person at 400 S. Vicentia Avenue; the City does not publish a separate universal transfer fee beyond the setup and applicable timing charges.
