Plan. Applying a fixed and variable fee structure is an
industry best practice to support the Region's water and
wastewater system.
Understanding your residential water bill
How your bill is calculated
The Region partners with your local hydro utility to
produce a combined bill for your household's hydro
and water charges. Your bill is calculated by adding your
monthly fixed-service charge (based on meter size) to
your consumption charge (based on your water usage).
Bills are typically issued every two months for residential
customers, and every month for industrial, commercial and
institutional customers.
2026 water and wastewater rate increase
How the 2026 rate increase will be used
Effective January 1, 2026, your combined water and
wastewater rate will increase by 6.0 per cent. This increase
supports:
- operations and maintenance to keep our drinking water
safe and of the highest quality (2.5 per cent);
- capital financing of the State-of-Good-Repair Program
(3.0 per cent); and
- enhancements to the Basement Flooding Mitigation
Program (0.5 per cent).
