Water Rates and Charges

Understanding Your Water Bill

Water and wastewater charges are billed by Oakville Hydro on behalf of Halton Region; who set the water and wastewater rates. Your total bill is made up of:

  • A monthly service charge based on meter size
  • A consumption charge based on 100% of water consumption

The Halton Region Water & Wastewater Rates for 2024 were approved and take effect on January 1, 2024. These rates include a combined increase of 4.3% over 2023 rates. To view Halton Region’s 2024 Rate Card, click here.
