As floodwaters begin to recede, residents may be eager to remove water from their basements. However, pumping a basement out too quickly can cause serious structural damage.
The water surrounding your home is putting pressure on your foundation. If you remove the water inside your basement too quickly, the difference in pressure can cause basement walls or floors to crack or even collapse.
Before You Start
- Never enter a flooded basement unless you know the electricity has been shut off.
- Always assume electrical equipment and wiring remain energized until Manitoba Hydro has confirmed it is safe.
- • If your property has been affected by flooding and you require your power to be disconnected, contact Manitoba Hydro at 1-888-624-9376.
- Take photos of any damage before beginning cleanup for insurance purposes (MORE INFO)
- Wait until floodwaters around the outside of your home have receded before pumping out your basement.
- Never use gasoline-powered pumps or generators indoors. They produce deadly carbon monoxide gas

How to Pump Your Basement Safely
- Pump out only 2 to 3 feet of water at a time.
- Mark the new water level and wait overnight.
- Check the water level the next day.
- If the water has risen again, stop pumping and wait another 24 hours before repeating the process.
- If the water has not risen, pump another 2 to 3 feet and repeat the process.
- Continue gradually until the basement is completely drained.
