Sewer back-ups occur when the storm or sanitary sewers become too full and the sewage flows backwards into residents' homes. It is more common for this to happen with sanitary sewers that have downspouts, weeping tiles, foundation drains, or sump pumps connected to sanitary sewers. The rainwater from these sources drains into the sanitary sewers and quickly over-fills them during large storms. In these situations, sewage will enter the basement, flowing up through floor drains and other plumbing fixtures.
By taking the right steps and being prepared, you can help keep your home safe from the effects of flooding.
Home Flood Protection Program |
|
The City of Burlington has implemented the Home Flood Protection Program to help homeowners reduce their risk of basement flooding and minimize damage if flooding occurs. The program offers homeowners up to 50 per cent of the cost of Home Flood Protection Assessments which aim to find potential ways that water/sewage can enter your home. These assessments are done by a trained third-party assessor and can be completed in-person or virtually based on homeowner preference. Subsidized in-person assessments cost $285 + HST (Regular price: $570 + HST). Subsidized virtual assessments cost $240 + HST (Regular price: $480 + HST). 20 assessments are available each year. |

A Household Drainage Survey is an in-home assessment that helps homeowners understand how water drains around and away from their property. It provides information about:
Halton Region requires confirmation of any stormwater connections to the wastewater system to determine whether the work qualifies for a subsidy. This information can help identify issues that may increase the risk of basement flooding. You may qualify for a Household Drainage Survey if your home:
If you would like to confirm if you are located within a region-defined priority area, confirm if you are eligible, and/or request a survey, please email Halton Region or call 311.

This cost qualifies as part of the existing rebate limits for eligible projects completed under the subsidy program. |
Conservation Halton Programs |
Rainwater Conservation FundMost of our infrastructure has been designed to move water through our urban landscape as quickly as possible. As a result, creeks and other bodies of water are overwhelmed with the amount of water and suspended particulates during rainfall and snowmelt. The Rainwater Conservation Fund supports urban landowner projects, greenhouse projects and nursery projects that divert and infiltrate rainwater into the ground on the landowner’s property. Landowners living in Aldershot, Brant Hills, Tyandaga and part of North Burlington are eligible to receive a grant of up to $7,500. Learn more about eligible projects, guidelines and application process.
Water Quality and Habitat Improvement ProgramMost of the natural area in the watershed is owned and managed by private landowners, so the health of our communities and environment depends on their efforts. The Water Quality and Habitat Improvement Program is a funding incentive program that supports landowners who are carrying out projects that contribute to water and habitat quality.

Do you know what your home insurance covers when severe weather strikes?
When it comes to flooding, not all water damage is treated the same by insurance providers. Coverage for sewer backups and overland flooding is often optional and may need to be added to your policy. Understanding what is covered (and what isn't) before an emergency happens can help you avoid unexpected costs and make informed decisions about protecting your home or rental property.
This webinar explains how home insurance works when you need it most, including the differences between common types of flood-related damage, what coverage options are available, and questions to ask your insurance provider.
If you notice flooding on streets, roadways, parks or other public areas, please contact Service Burlington by call or email. These types of surface flooding are managed by the City of Burlington.
If you experience flooding in your basement or yard during a rainfall event, complete Halton Region’s Report a Property Flood online form or call 3-1-1 to report. Include photos or video of the flooding and damage with the form as this will help support investigations. Please note that Halton Region staff do not conduct in-home visits during extreme weather events.
If there is immediate danger, dial 9-1-1.
