Overland Flooding: What Residents Need to Know

By: Jennifer Beard

Our region saw more than 100 mm of rain in just a few hours last night, and that kind of sudden downpour has caused overland flooding, water across several roads, and lift stations running right at—or even past—their limits. Many homes are dealing with sewer backups and rising water, and crews are working hard to stabilize the situation. While things dry out and systems catch up, here are a few practical tips to help you stay safe, protect your home, and reduce strain on municipal infrastructure.

1. Avoid Flooded Roads

Water can hide washouts and debris. Do not drive through water-covered roads.  Use caution when driving over roads that were flooded, as they may still be unstable.

2. Reduce Water Use

Limit flushing, laundry, showers, and dishwashing until lift stations are fully restored.

3. Keep Sump Pumps Discharging Outside

Do not pump water into floor drains or the sewer system. This increases the risk of backups.

4. Turn Off Electricity in Flooded Areas

If water has reached outlets or appliances, shut off power to that area before entering.

5. Document All Damage

Take photos and videos of flooded basements, damaged belongings, and sewer backups for insurance and disaster assistance.

6. Use Protective Gear During Cleanup

Wear gloves, boots, and masks. Sewer water contains bacteria and chemicals.

7. Keep Children and Pets Away from Floodwater

Floodwater may contain sewage, fuel, and other contaminants.

8. Check on Neighbours

Seniors and vulnerable residents may need help with pumps, cleanup, or transportation.

9. Do Not Use Flooded Appliances

Have furnaces, water heaters, and freezers inspected before turning them back on.

10. Ventilate Your Home

Open windows and use fans or dehumidifiers to reduce mould growth.

11. Clear Ditches and Culverts (If Safe)

Remove debris blocking water flow. Report major blockages to the municipality.

12. Follow Municipal Updates

Watch for notices on lift station status, road closures, boil-water advisories, and waste disposal instructions.

13. Separate Flood-Damaged Waste

Bag contaminated items separately. The municipality may announce special disposal days.

14. Test Private Well Water

If you use a well, assume contamination until testing confirms safety.

15. Contact Your Insurance Provider Early

Start your claim and keep receipts for cleanup, pumps, fuel, and temporary accommodations.
