Provider-specific findings
Relief research for this provider
The notes below may document a route, rule, or explicit public-information limit. General preparation steps are not represented as utility policy.
- Emergency reporting route
- (951) 736-2234 is the Utilities Department emergency line for water outages, main breaks, and urgent water issues. During Monday–Thursday working hours, call the same number; after hours and on weekends, call and press option 4 for standby emergency assistance. Routine billing and account issues use (951) 736-2321. Call 911 for an immediate life-threatening emergency.
- Leak-adjustment policy
- Corona uses a water-budget variance process rather than a simple automatic leak-credit percentage. Residential budgets combine an indoor allowance based on household size and an outdoor allowance based on irrigated landscape area; the default indoor budget is four residents at 47 gallons per resident per day. After repairing a leak or filling a pool, a customer may request a one-time budget variance online, by email, or by mail to City of Corona Utility Billing Division, P.O. Box 950, Corona, CA 92878-0950. The customer should describe the event, repair date, readings, and supporting documentation and submit promptly to CustomerCare@CoronaCA.gov. If the customer disputes the amount used, the City reads the meter and checks for leaks; if no leak is found, the customer may request a variable-flow meter test. A meter found more than 2% fast produces a refund of the contested billing-period overcharge; an accurate meter or meter registering low leaves the customer responsible for the test fee. The City’s public material does not publish a universal private-leak credit cap or receipt deadline.
- Utility assistance program
- Corona offers Promise Pay installment plans for past-due balances and directs customers to Riverside County Community Action Partnership CARES for emergency assistance with water, sewer, garbage, utility, technology, and special-needs bills. The City’s public pages describe CARES and the former or temporary LIHWAP resource but do not publish a recurring senior, disabled-veteran, or low-income water-rate discount cap. Customers with unusual hardship may request a reasonable extension or fee reversal from the Utilities Director under the municipal code; the City also provides water-budget variances for household size, repaired leaks, and filled pools.
- State and federal aid connection
- Corona’s bill-assistance page directs residents to Riverside County Community Action Partnership CARES and previously described LIHWAP assistance of up to $2,000 for eligible past-due water and sewer bills. Because California’s current CSD page states that the federal LIHWAP application period has ended, customers should verify current program status at https://www.csd.ca.gov/waterbill rather than assume a new application is available. Corona’s local workflow is to call Customer Care at (951) 736-2321, ask for a Promise Pay arrangement, and contact CARES through https://capriverside.org for local emergency screening. The City does not publish a separate senior or disabled-veteran utility-credit application.
