Preparing for heavy rainfall
Homeowners can take these steps to reduce the likelilhood of their homes flooding.
- Grade and landscape your lot to move water away from the house
Grade and landscape to make sure there is a positive slope away from the wall for at least the first 1.5 metres (5 feet). The ground should drop a minimum of 75mm (3 inches) in this area.
Use landscaping to disperse the water more evenly. Aerate your lawn, especially if it is hard and compacted; this will help water soak into the ground.
Water flow from downspouts should be directed at least 1.5 metres from the basement wall. Seal any cracks between your house and driveway. - Make sure your backwater valve or sump pump is working
Flush, clean and exercise your backwater valve to make sure it moves easily.
Check your sump pump by slowly pouring water into the sump tank. Watch for the "float" to rise and trigger the pump. Once the pump has started, the water level will quickly lower and the float will shut off the pump. - Reduce your water use
During times of heavy rain, conserving water in your home can help reduce the demand on our sewer system. This can help reduce sewer backups. - Leave natural plants along the shoreline of stormwater ponds
If you live beside a stormwater pond, leave natural plants along the shoreline. The plants help to slow the flow of water. Stormwater ponds were built to accommodate rainfalls, and rising of the water levels in the ponds is normal. It may take up to two days of dry weather for the water levels in the stormwater ponds to return to normal.
