Basement Flooding Protection Subsidy Program (BFPSP)

To report basement flooding, please call 311 or visit

New: "Fast-Track" Option

In light of the on going COVID-19 pandemic, the City is implementing a "fast-track"’ option, effective April 1, 2020, allowing residents to continue through the Basement Flooding Program until inspections can commence again. The fast-track option still requires an application to be submitted prior to beginning the work, however, the applicant will not have to wait for the courtesy inspection to be performed before having a plumbing contractor perform the work. See details on the "Fast-Track" process.

Prior to obtaining a permit, the plumbing contractor is required to provide the following:

  1. Preconstruction photos of the area of work

Note: Due to the fact that a final determination of eligibility of the work performed does not occur until after the City of Windsor building inspector has performed the final inspection on the building/plumbing permit, there is some risk to the property owner that they may not be entitled to receive a subsidy payment.

What is the Basement Flooding Protection Subsidy Program?

The City of Windsor makes improvements annually to its 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.

The City is offering owners of residential dwellings (single family and duplex homes) 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.

Visit our Flooding page for more information on how to reduce basement flooding.
