What can cause a high water bill?

The City lists changed usage patterns, household leaks, leaking toilets, appliances, meter-reading error and estimated readings. Compare consumption with previous periods before choosing a remedy. A higher total can involve both usage and fixed charges.

Can I receive a warning before the next bill?

MyWaterAccount can send alerts when use reaches a daily, weekly or monthly amount you choose. The City provides a setup video. An alert helps identify unusual use but does not repair a leak or automatically submit an adjustment application.

Which customers can apply for leak relief?

Residential customers and residential not-for-profit organizations may qualify. The high bill must have been issued within the last 90 days. This is a limited policy, not a general discount for every water customer or every large bill.

Leak-relief eligibility and proof

How much higher must consumption be?

The page says additional water billed must be at least twice the customer's average consumption. Ask the Billing team to apply the policy to the actual history rather than treating a doubled dollar total as the only test.

Are there limits on repeat adjustments?

No adjustment can have been granted in the last 12 months, and no more than two adjustments are allowed within a ten-year period. Check prior account adjustments before assuming a new leak is eligible.

Must the leak be repaired first?

Yes. The high-water problem must be identified and repaired, and proof of repair must accompany the application. Keep invoices or other evidence requested by the City. Use the online high-water adjustment form after assembling the documents.

What review is needed before an appeal?

How do I send an eligible appeal?

Email the Billing team with the concern's details and Water Billing Appeal in the subject line. Include the account, bill and prior discussion details requested. The appeal route is separate from simply reporting a leaking fixture.

Which pipes and equipment belong to the owner?

Owners maintain private service pipes from the property line into the building, internal plumbing and valves. The water meter itself belongs to the City. Contact Public Works through 519-623-1340 about municipal infrastructure problems; private leaks require the owner's repair arrangements.
