Sanitary Backwater Valve Rebate Program

Peel Region offers a sanitary backwater valve rebate of $700 for eligible homeowners.

The sanitary backwater valve rebate is a subsidy program. It helps homeowners cover the cost of installing a sanitary backwater valve to reduce basement flooding due to rainfall.

Other information

Backwater valves can be an effective way to stop wastewater from backing up into your basement, but they’re not suitable for all homes.

Before you apply, be sure that a backwater valve installation is the right decision for your property.

Consider that:

  • A backwater valve must be installed by a licensed professional. Installation is expensive and complex.
  • Even when a backwater valve is installed correctly, basement flooding might still result from water sources other than the sanitary sewer.
  • Backwater valves require ongoing maintenance.

The following resources about sanitary backwater valves can help you make an informed decision.



If you’ve done your research and feel that a backwater valve is right for your home, arrange an in-depth investigation of your plumbing by a licensed plumber.

You’re eligible for the Sanitary Backwater Valve Rebate Program if you have been flooded as a result of an excessive rainfall. Proof of the flooding incident will be required.

If you have not been flooded or do not have proof of the incident, please contact us at 905-791-7800, extension 4409 to confirm your eligibility.

You will not qualify for the program if you’ve already received a subsidy from Peel Region through a previous basement flooding subsidy program.

To receive the rebate, you must submit a complete Application Package that includes:

  • Confirmation that all of your downspouts have been disconnected or a signed Acknowledgement and Release form.
  • A building permit from the City of Brampton, the City of Mississauga, or the Town of Caledon.
  • Confirmation that the installed sanitary backwater valve adheres to the Ontario Building Code.
  • Confirmation that your sanitary backwater valve was inspected, and your building permit was signed by a municipal inspector.
