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
- 909-395-2678 for water leaks, open or leaking fire hydrants, water-quality questions, and utility emergencies during OMUC hours. After hours, contact Ontario Police Department Dispatch at 909-986-6711 for water-related needs. OMUC’s posted regular hours are Monday–Thursday 7:30 a.m.–5:30 p.m. and Friday 7:30 a.m.–4:30 p.m.
- Leak-adjustment policy
- Ontario’s current customer pages do not publish a guaranteed private-leak bill credit, repair-receipt deadline, historical-average formula, or adjustment cap. OMUC maintains the City-owned portion of the service line through the meter; the customer’s responsibility begins after the meter. A high-bill customer should call 909-395-2678, request a leak or meter investigation, preserve meter readings, photographs, and licensed-plumber invoices, and ask Customer Service whether the current SB 998 disputed-bill or meter-testing procedure applies. Any adjustment must be confirmed by the City; the reviewed materials do not promise automatic forgiveness.
- Utility assistance program
- Ontario offers a Disabled Person’s and Senior Citizen’s Discount for eligible customers, with a published maximum of up to $15 per month off the combined water, sewer, and refuse bill. Applications and supporting documentation are submitted in person at 1333 S. Bon View Avenue. Ontario also offers payment plans for past-due balances; new bills issued after a plan is established remain separately payable. The reviewed pages do not publish a larger water-only credit or annual assistance cap.
- State and federal aid connection
- Ontario’s customer-service page provides local payment plans and the disabled/senior discount but does not publish a direct LIHWAP application workflow or named charity payment partner. Customers with hardship should contact 909-395-2050 before shutoff and ask about the current plan and SB 998 options. They should also check California’s current LIHWAP information at https://www.csd.ca.gov/lihwap and county assistance programs.
