Caledon homeowners get their main basement-flooding rebate through the Region of Peel: 60% of the cost of installing a sanitary backwater valve, up to $1,500. The valve stops wastewater from backing up into your basement when the sanitary sewer overflows.
Why Caledon homes need this
Caledon mixes established towns and fast-growing subdivisions where heavy storms can surcharge the sanitary sewer. A sanitary backwater valve is the core device the Region subsidizes against sewer-backup flooding.
What the rebate covers
Combined under the up to $1,500 program cap. Per-measure limits may apply — confirm current amounts with Region of Peel before you start.
Read this before you spend a dollar
Get your building permit from the Town of Caledon and confirm eligibility before installation — the Region pays after the passed inspection, on the paid invoice.
