Oil and grit separators

A stormwater oil and grit separator is an underground device that captures oil and sediment from storm events, runoff and snowmelt. Capturing these contaminants prevents them from entering Nose Creek, and eventually the Bow River.

Oil and grit separators are located at:

  • Gas stations
  • Industrial and commercial sites
  • City property such as public works yard, arenas and some roadways

Submit maintenance records annually

The City requests that stormwater oil and grit separator maintenance records are submitted to annually.
