Leak relief and household assistance

A high water bill may have a path to review

Hidden plumbing failures can produce an alarming bill before the problem is visible. This guide separates what Fontana Water Company, a San Gabriel Valley Water Company division publicly describes from the practical steps every customer can take while requesting help.

Provider-specific review

What the public record says about a leak adjustment

Fontana’s customer pages explain that a high bill is often caused by landscape irrigation leaks, broken sprinkler heads, leaky or continuously running toilets, or open valves, and direct customers to inspect the property and contact Customer Service. The public pages reviewed do not publish a private-leak adjustment percentage, repair-receipt deadline, calculation formula, or lifetime cap. Fontana separately publishes CPUC Rule 18 meter-testing and meter-error adjustment materials; a customer disputing a meter reading should request the applicable meter test or bill-review procedure. Customers should document the abnormal readings, promptly repair the leak, retain invoices and parts receipts, and ask Customer Service whether a case-specific adjustment is available; no private-leak credit should be assumed automatically.

Stop the loss

Shut off the failing fixture or supply and arrange a qualified repair.

Keep proof

Save dated invoices, parts receipts, photographs, and meter readings.

Request review

Submit the request promptly and keep paying any undisputed amount.

Utility assistance

Customer assistance and eligibility

Fontana Water Company offers the CPUC-regulated Customer Assistance Program (CAP) for qualifying low-income households. The company’s official 2026 fact sheet estimates that a 5/8-inch customer using 12 CCF would pay about $74.15 per month under CAP versus $90.50 without CAP after the 2026 rate change. Eligibility and income thresholds are set by the current CAP tariff and Form 16B; the linked June 1, 2026 CAP PDFs were not readable through the native browser, so the exact income table and maximum credit are not publicly stated here. The company also offers critical-care protections and third-party notifications but no separate published senior or disabled-veteran rate discount.

State and federal connections

Where to ask for broader aid

Fontana’s CAP is administered under CPUC tariff rules and its Form 16B notice/application. The company’s regulatory materials identify California-regulated customer assistance and critical-care processes, but the reviewed pages do not describe direct LIHWAP intake, local charity vouchers, or a federal benefit payment-posting workflow. Customers should contact Fontana Water Company at (909) 822-2201 before the notice deadline, request the current CAP Form 16B, and separately review California’s current LIHWAP resources at https://www.csd.ca.gov/lihwap and county assistance programs.

Leak and assistance notes

Build the file before asking Fontana Water Company, a San Gabriel Valley Water Company division for relief

A high bill can have several causes, including a hidden plumbing failure, irrigation use, a meter issue, a change in occupancy, or a rate adjustment. The provider’s leak policy determines whether any credit is available; an unusually high bill does not automatically qualify.

Keep a dated record of the reading, the suspected source, the repair, the contractor or parts receipt, and the return to normal use. Ask whether the utility requires a specific form, a licensed repair, a meter test, photos, or a request within a fixed number of days.

For income-related difficulty, ask about local assistance, payment arrangements, state programs, and community referrals separately from a leak adjustment. These programs often use different applications, documents, funding limits, and deadlines.
