High river levels increase risk of basement flooding

Homeowners advised to check sump pumps and backwater valves and ensure drainage is directed away from homes

Winnipeg, MB - Winnipeg property owners are advised that there is an increased risk of basement flooding due to current high river levels and potential for rain this weekend. The Red River is expected to rise to between 14 and 15 feet at James Avenue by Tuesday or Wednesday next week.

High river levels increase the risk of basement flooding across the City. Although basement flooding is a risk any time of the year, the risk increases with high river levels because the sewer system must then rely heavily on pumping stations rather than gravity to carry the rainfall runoff.

What can be done to protect your home?

The following protective steps can greatly reduce the risk of sewer backup and basement flooding:

  • Install a backwater valve and sump pit drainage system
  • Check and maintain your backwater valve and sump pit drainage system regularly
  • Improve drainage around your house

Property owners are reminded it is illegal to drain sump pump water into the basement floor drain or any other part of the house plumbing system, as it can overtax the sewer system placing their basement and those of their neighbours at risk of flooding and damage.

Homeowners are also encouraged to take advantage of the Basement Flood Protection Subsidy Program. The program was launched by the Province of Manitoba and the City of Winnipeg in 2011 to help homeowners protect their basements from flooding caused by overloaded sewers during severe weather (e.g., heavy rain, high river levels). Homeowners can apply for a subsidy of 60 per cent of the invoiced cost, up to a maximum subsidized amount of:

  • $1,000 for installing an in-line backwater valve only,
  • $2,000 for installing a sump pit drainage system only,
  • $3,000 for installing both an in-line backwater valve and a sump pit drainage system

More information on basement flood protection and the Basement Flood Protection Subsidy Program is available on the following web pages:

The City also reminds citizens to be cautious around fast moving rivers and creeks.
