Basement Flooding Protection Subsidy Program (BFP)

The City of Windsor makes improvements annually to the complex system of underground pipes, sewers and catch basins. However, these improvements alone cannot completely protect a home from basement flooding. With increasingly frequent and severe weather events related to climate change, it is essential that residents take the appropriate action to reduce the risk of basement flooding on their own private property.

On May 3, 2011, to assist homeowners, Windsor City Council approved a Basement Flooding Protection Subsidy Program. (Council Report)

What is the Basement Flooding Protection Subsidy Program?

The City is offering residents a financial subsidy to install a sump pump with sump pump overflow and/or backwater valve(s) and/or disconnect foundation drains from the floor drain.
