How the program works
What the Peel backwater valve rebate covers
A sanitary backwater valve stops sewage from flowing back into your basement when the municipal sewer surcharges during heavy rain. Peel Region offers a rebate to help Mississauga, Brampton and Caledon homeowners install one.
We install mainline backwater valves in Mississauga homes, including the permit and inspection, and give you an itemized invoice so your rebate application is complete.

Protect more than the sewer connection
The Peel rebate covers a sanitary backwater valve. Many Mississauga homes also benefit from a sump pump, downspout redirection and better lot grading. We look at the whole property and quote each item separately, so you can decide what to do now and what can wait.
