Sewer laterals that are in substandard condition (e.g., cracks, holes, root damage) may create blockages or poor drainage that can prevent wastewater from flowing from your home to the municipal sanitary sewer system. This can leave your home at risk for sewer back up and basement flooding.
The sewer (wastewater) lateral is the pipe that runs underground from your home to the sewer wastewater main under the street. It carries all the sewage (wastewater) from your drains such as toilets, showers, sinks, washing machine and dishwasher.
Substandard conditions such as cracks in the sewer lateral pipe can encourage root infiltration into the pipe. As the roots accumulate in the pipe, they create a blockage which prevents wastewater from properly draining. This can result in a wastewater (sewer) backup in your home.
Halton Region’s Sanitary Lateral Lining and Repair subsidy covers 50% of costs incurred for materials and labour charged to repair the sanitary lateral (underground sewer/wastewater pipe), up to a maximum of $2,000.
A Backwater Valve provides additional protection against basement flooding. Undertaking sewer lateral repair offers a good opportunity to also install a Backwater Valve at the same. Please see our Backwater Valve Installation subsidy for more details on how to qualify for this subsidy.
Please review the full Terms and Conditions in the subsidy application form before beginning backwater valve installation and/or sanitary lateral repairs.
