Protect your home from basement flooding
Basement flooding protection subsidy program
The 2015 Program is closed. We will continue to accept applications and when funding becomes available we will continue to process applications in the order in which they were received.
The City of Winnipeg and Province of Manitoba have introduced a subsidy program to help homeowners protect their basement from flooding caused by overloaded sewers during severe weather (e.g., heavy rain, high river levels).

- The subsidy is not available to any homes that were required by Building or Plumbing Codes to have a backwater valve and/or sump pit drainage system installed at the time of construction, namely:
- homes built since 1979, which were required to have backwater valves, and

Installing the sump pit drainage system
This work may be done under either a plumbing permit (already required if you are having an in-line backwater valve installed) or a building permit. Only labour costs from a plumbing contractor licensed by the City of Winnipeg or a building contractor are eligible for the subsidy:
- If you are hiring a plumbing contractor, the plumber must take out the plumbing permit and be responsible for installing the sump pit drainage system.

Please note – work done by the property owner is not eligible for the subsidy
How to apply for the subsidy
Depending on the plumbing in your house, you may require one or more in-line backwater valves of either the normally open or normally closed type to properly protect your basement from flooding. We recommend that you consult with a plumbing contractor licensed by the City of Winnipeg for an assessment of the cost involved in installing any of the following eligible devices. For backwater valve installation requirements, see the Manitoba Plumbing Code.
An in-line backwater valve:
- must be installed in your main sewer pipe or the basement branch line of your home so that it protects all fixtures below grade from sewer backup,
- must close if sewage backs up from the main sewer, and
- must be a Manitoba Plumbing Code approved device.

Note: Backflow devices installed in the floor drain protect only the floor drain, not any other basement plumbing. These devices are not eligible for the subsidy program.
- The system includes a sump pit, a sump pump and a discharge pipe.
- The sump pit must be constructed in accordance with the Winnipeg Building By-law and the Basement Flooding Protection Subsidy Program By-law.
- The sump pump must comply with subsection 23.2 of the Winnipeg Building By-law.
- The discharge pipe must drain the water to comply with the Lot Grading By-law.
Before hiring a contractor (e.g., plumbing, electrical, building), we recommend that you:
- get at least three estimates (ask friends and neighbours for referrals),
- ask for and check contractor references, and
- call the Better Business Bureau for a reliability report on contractors.
Ensure that appropriate permits are obtained from the Planning, Property and Development Department. The contractor must take out the permit(s) (e.g., plumbing, electrical, building). You will need to write the permit number(s) on your application.
- You must arrange for the necessary inspection of the eligible installation once the installation is complete. Your contractor may arrange the inspection for you.
- Note: The final inspection must take place before enclosing or covering the eligible installation. If the inspector is not able to see if the installation meets the applicable Building Code requirements, he or she cannot sign off on the final inspection.
If you are claiming labour costs performed by your contractor, obtain an itemized invoice from your contractor showing:
- the address of the eligible installation,
- the name and licence number of the contractor,
- a cost breakdown of all charges, verifying installation of an in-line backwater valve approved by the Manitoba Plumbing Code and/or a sump pit drainage system, and outlining in detail the eligible installation that was done, and
- the total amount paid and be clearly marked as "paid in full".
