Basement flooding protection subsidy program – Frequently asked questions (FAQ)
The Basement Flooding Protection Subsidy Program did not receive funding for the 2017 program year and has now been canceled by City Council. As a result, any applications received after December 30, 2016 have and will not been processed.
All new homes built since 1979 were required to have an in-line backwater valve. However, some older homes may have had an in-line backwater valve installed after construction.

We recommend that you have both of these devices to protect against basement flooding.
An in-line backwater valve is designed to prevent sewage in an overloaded main sewer line from backing up into your basement.
The sump pit, set into the basement floor, collects water from the weeping tiles around your basement. The pump pushes the water outside your house through the discharge pipe.
If you do not install a sump pit drainage system, weeping tiles connected to the sewer line can't drain when the in-line backwater valve closes, causing water from your weeping tiles to overflow into your basement from the floor drain.
A dedicated electrical circuit is required to reduce the chance of the circuit breaker tripping due to another device being placed on the same circuit and overloading it.
Yes. However, we recommend that you hire a plumber licensed by the City of Winnipeg because of the complexity of retrofitting this device into an existing home.
If you choose to install the in-line backwater valve yourself you will still need to take out the necessary permits and have the work inspected by a City inspector.

If you choose to install a sump pit drainage system yourself you will still need to take out the necessary permits and have the work inspected by a City inspector.
Yes. You must ensure that appropriate permit(s) are obtained from the Planning, Property and Development Department, before work begin and arrange for the required inspection of the eligible installation. The person listed on the permit will be responsible for the quality of the work.
If you are claiming eligible labour costs, the contractor must take out the permit(s) and you must write the permit number(s) on your application form.

Every installation is different, so we recommend that you contact a plumbing contractor licensed by the City of Winnipeg for an estimate.

We recommend that all properties have an in-line backwater valve and sump pit drainage system. No matter where you live in Winnipeg, your home is at risk of basement flooding. Heavy rainstorms that fall over short periods of time can overwhelm City sewer systems. Overloaded sewers can back up through house sewer lines and flow into basements that aren't protected. Even if you have never had any basement flooding before, severe weather (e.g., heavy rain, high river levels) can cause basement flooding in unprotected homes.
Ask your plumber for their licence number. If you are unsure, please contact City of Winnipeg Planning, Property and Development Department by phone at 204-986-5140 or by email. A permit will not be issued to an unlicensed plumber.
Ask your electrician for their licence number. If you are unsure, please contact City of Winnipeg Planning, Property and Development Department by phone at 204-986-5140 or by email. A permit will not be issued to an unlicensed electrician.
No. If you are hiring a building contractor to install your sump pit drainage system, 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.
Ask your contractor to give you a copy of the permit(s). You will need to write the permit number(s) on your application form. If you still have concerns, please contact Planning, Property and Development by phone at 204-986-5140 or by email.
