Water Billing

All properties in the Town of Grimsby below the Niagara escarpment are billed for water services.

The Town of Grimsby offer its residents many options to pay their water bill.

Changes Coming to Your Water and Wastewater Bill in 2026!

Big changes are coming to how Grimsby residents are billed for water and wastewater services starting in 2026.

Here's what's changing:

One combined bill: All properties will now be billed for 100% of water and wastewater services directly on the water bill.
No more wastewater levy on the tax bill: The wastewater tax levy (SAR) will be eliminated beginning in 2026.
Bills will be based on your meter size (for fixed charges) and your actual water usage (for variable charges).
Billing timelines will increase from tri-annual to bi-monthly, helping customers track water use and manage their budgets more easily.

The new system is consistent and easy to understand for everyone. Customers with the same meter size and consumption will pay the same amount.

Visit our Let’s Talk Grimsby page for lots more information about these changes, timelines and Frequently Asked Questions.
