Oil-Grit Separator Project 2018

In late 2018 the City of Calgary’s Water Services commenced installation of the second of two oil-grit separators (OGS) in Valley Ridge as part of the City’s program to update all storm water ponds. An OGS is an underground “filtering box”, designed to capture sediment, debris and separate oil from the storm water runoff before it gets into the settling ponds. The OGS provides a much more convenient way (hydrovacing) to remove the sludge from the storm water before it ultimately enters the Bow River.

In 2017, a similar, but larger OGS system was installed beneath Valley Creek Road to filter storm waters before entering the storm water pond on the 12^th hole.

The 2018 project was completed in early January 2019. The project also included dredging of the storm pond located south of the 13th green on the golf course. Follow-up remedial landscaping work occurred in Spring 2019 replacing trees removed from the median and replant grass over the construction site.
