Basement Flooding Subsidy Program

The City of Windsor introduced a basement flooding subsidy program in 2011. This program was implemented to help prevent the costly flooding of a basement by subsidizing the cost of a sump pump with sump pump overflow and/or backwater valve(s).

The maximum eligible subsidy is $2,800 per home/unit. Coverage is as follows:

  • Install backwater valve(s) (licensed plumber required) – Up to 100 percent of cost, ($1,000 maximum)
  • Install sump pump with sump pump overflow and disconnect foundation drains to floor drains – Up to 100 percent of cost, ($1,750 maximum)
  • Install only sump pump overflow to discharge outside to surface (applies to existing sump pumps only) – Up to 100 percent of cost, ($300 maximum)
  • Install backwater valve and sump pump with sump pump overflow – Up to 100 percent of cost, ($2,800 maximum)
  • Disconnect foundation drains from floor drain and/or dye testing and camera work as required – Up to 100 percent of cost, ($400 maximum)
  • What this program does not cover:
    • The replacement of an existing sump pump
    • The upgrade of a sump pump
    • The addition of another sump pump
    • The installation of a sump pump when the foundation drains are already separated from the floor drain or sanitary sewer
    • Work performed for which a permit cannot be obtained

There are specific program requirements by the city.

  • All eligible basement flooding protection work must be performed by a contractor/licensed plumber of master plumber. The plumber or master plumber should be able to present a current City of Windsor Licence. If you have any concerns about whether or not the plumber is licensed, please contact the City’s Licensing Department at (519) 255-6200 or call 311.
  • If a backwater valve is installed by a contractor, a licensed plumber must certify its installation.
  • If a sump pump is installed, please ensure the disconnection and capping of leads from the foundation drains to the floor drains.
  • Any work performed by the homeowner themselves does not qualify for subsidy.
  • Disputes with respect to qualifying work will be resolved by the City Engineer and/or the Chief Building Official or their designate.
  • The contractor must use material or fittings that are approved by the Ontario Building Code.
  • A building plumbing permit and an approved final inspection must be obtained for backwater valve and sump pump installations.
  • The contractor must obtain the permit within 60 days of receiving Building Inspector approval to proceed with eligible work under the program
