Severe rain events can overwhelm the City’s wastewater and storm water sewer systems, especially in older neighbourhoods where the systems weren’t designed and constructed up to today’s standards. Markham has invested millions of dollars to improve City sewer systems. To further protect properties from basement flooding, City Council has endorsed the Private Plumbing Protection Rebate Program. The program offers financial support for property owners who are making certain improvements on their private plumbing system.
Three private plumbing protection measures can be implemented to help protect your property.
- Backwater Valve Installation. A backwater valve is a device that acts as a ‘check valve’ that allows sewage or stormwater to flow out of the home’s plumbing system during normal conditions, and prevents back flow of sewage or stormwater into your home during storms.

- Weeping Tile Disconnection and Sump Pump Installation. Weeping tiles (also called foundation drains) collect groundwater or infiltrated rainwater from around the outside of homes and may directly connect to municipal sewer systems. Disconnecting weeping tiles from municipal sewers and installing a sump pump can help prevent infiltration flooding through foundation walls or the floor when municipal sewers surcharge during large storm events.
- Sanitary and Storm Lateral Relining and Repair. Sanitary and storm laterals are underground pipes that carry wastewater or drainage away from your property to the City sewer systems. Blocked or collapsed laterals can cause a sewer backup in your basement.
