Stormwater Management

Stormwater Management aims to protect the community and the environment from stormwater runoff, created by rain and snow melt events, by controlling stormwater quality and quantity. Before infrastructure development, water would be absorbed into the ground after it rains.

After infrastructure development, hard surfaces like roofs, driveways, roads, and parking lots prevent absorption, increasing the amount of water collected by storm drains. Before stormwater reaches the storm system, stormwater flows over these hard surfaces, accumulating debris, chemicals, and other pollutants that can have a negative impact on surrounding aquatic ecosystems. Once the stormwater reaches the storm sewer system, water flows through​ a large, complex network of pipes and waterways until its eventual release back into the natural environment.

The Township’s stormwater management system is made up of many components that protect the community and environment, such as:

  • 28 stormwater management facilities (ponds)
  • 13 oil and grit separators
  • 1,500 culverts
  • 2,200 catch basins
  • 100 km of storm sewers
  • 350 km of roadside drainage ditches

In order to fund the maintenance/upgrades of this infrastructure, and to comply with provincial regulations, the Township will be implementing a Stormwater Management Rate to start in 2024. See Council Report PW-CAP-2023-004 and By-Law 2023-056. Half of the rate will appear on each of your bi-annual property tax notices.
