Flood prevention and spring flooding


Prevent flooding! 

During heavy rains, a home is vulnerable to water damage such as: water infiltration, equipment breakdowns or sewer back-up. 

It is recommended that you have your property inspected regularly to maintain it, detect any defects and take corrective action, if necessary. 

Compliance with standards and bylaws is also required. Preventive measures may be taken as well. 

1. Exterior building envelope

Make a regular visual inspection of cladding, foundations and caulking to detect any defects and have a professional carry out any necessary repairs.

2. Gutters and downspouts

Extend downspouts to keep water away from the foundation and driveway leading to a basement garage, if your home has one.

3. Sloping grounds on property

Landscape your grounds to keep water away from the building.

4. Sump pump

Every year, check that it is in good working order. 

5. Check valve (also called a “non-return valve”)

A check valve is a simple device. It allows water to flow in one direction only, i.e. toward municipal facilities. A check valve has a slanting flap that closes when water tries to flow in the opposite direction, thereby protecting your home.

Under Bylaw 802 on construction, this required protective device must be installed on all horizontal connections of equipment carrying wastewater, such as plumbing fixtures, floor drains, retention pits, oil separators, tanks, interceptors and other pipes or siphons installed in basements or cellars.

6. Driveway below street level

An old driveway built below street level must be constructed with an elevation so as not to catch runoff water from the street and must have a drain before the access door. 

The Town of Rosemère cannot be held responsible if water infiltration occurs where your devices and equipment do not comply with the various bylaws in effect.

We encourage you to read the document La gestion des eaux… une histoire de réseaux (French only) for advice on standards and good practices to prevent water infiltration in basements.


Spring flooding

Please note that the Town’s employees is monitoring the situation and is ready to intervene quickly if necessary.

Questions?

Citizens can contact the Public Works Department directly for any questions regarding flooding  at 450 621-3500 ext. 3300. For emergency calls, please dial 911.

It is the citizen's responsibility to ensure that they do what is necessary to protect their property.

Electricity

If the flood cannot be prevented but water has not yet started coming into the basement:

Cut the power to the whole house to prevent any risk of electric shock or fire by doing the following:

  1. Make sure you aren’t standing on a wet floor or leaning on anything made of metal.
  2. Flip the main breaker off.

If water has started coming into the basement:

Don’t touch anything! Call Hydro-Québec right away at1 800 790-2424 to have service to the meter or pole cut.


Preventive measures and emergency kit

Residents concerned are being urged to take certain preventive measures to ensure their safety and limit material damage:

· Move valuables from the basement to the ground floor as well as any other basement items that can be brought upstairs.

· Keep chemicals and toxic products, such as insecticides and other flammable products, in a safe place.

· Block floor drains in the basement to prevent water backflow.

Feel free to consult our information pamphlet or website for more information.

We also invite you to prepare an emergency kit.
