Urban Stormwater

Stormwater is rainwater that doesn’t soak into the ground.  It runs off rooftops, driveways, roads, fields and lawns. Effective stormwater management helps prevent flooding and damage to property, as well as preserve local ecosystems by safeguarding water quality.

In rural areas, ditches and culverts are the primary methods for directing stormwater away from properties and roads.  In urbanized areas, stormwater management may include storm sewers, catch basins and manholes that direct stormwater away from properties, roads, other vital municipal infrastructure and toward stormwater management facilities.  

Stormwater management facilities are specifically designed to protect downstream infrastructure from flooding by temporarily storing runoff and improving water quality by trapping pollutant-laden sediment in runoff.  The stormwater management facility provides centralized collection of polluted sediments which helps to prevent their uncontrolled release into rivers, streams and lakes where they can degrade water quality, harm aquatic life and adversely impact downstream recreational areas.

There are currently 25 urban stormwater management facilities located across the municipality. These facilities are comprised of:

  • Dry Ponds - detain water for a short period of time (less than 48 hours)
  • Wet Ponds - hold a permanent pool of water that releases treated stormwater back to the environment at a controlled rate
  • Low Impact Development (LID) Features - mimic natural water cycles by increasing stormwater infiltration into the soil where it is filtered and absorbed by plants and/or specialized filter media

​Environmental Services is available to respond twenty-four (24) hours a day, seven (7) days a week, three hundred and sixty-five (365) days a year for service calls or emergencies related to stormwater management facilities. All Environmental Services Technicians are licensed under Ontario Regulation 129/04 (Regulation Licensing of Sewage Works Operators).

Safety Tips to Consider Around Stormwater Management Facilities

Public access is strictly prohibited in areas adjacent to stormwater management facilities as water levels in these areas are subject to dramatic and rapid changes during periods of rain and snow melt. Site conditions including muddy water, sudden drop offs, subsurface currents, and the potential for entanglement with vegetation and debris are all possible.

Consider these safety tips around ​stormwater management facilities:​

  • Stay well back from the facility’s side slope, vegetated barriers, and outfall areas.
  • Be aware that water levels can rise rapidly, so never wade or swim in a stormwater management facility.
  • Do not dump garbage or other household waste (including used medical products, fertilizers, soap scum) into storm sewers, creeks or stormwater management facilities. These pollutants represent a community safety hazard and compromise the environment.
  • Never attempt to go on ice in a stormwater management facility, as fluctuating temperatures and the use of road salts can create thin or unstable ice and potentially hazardous conditions.
