On the outskirts of Edmonton, Alberta, the Clover Bar ravine acts as a funnel for the runoff of several industrial companies including a paving company with large sand, gravel, and asphalt cold mix storage piles. There is also the highly turbid surface runoff from local roadways and parking lots during rain events.
The problem is that in the ravine a fish bearing stream receives the particulate laden water and flows directly to the North Saskatchewan River four kilometers away. Because the stream and river are fish-bearing, an environmentally friendly solution was needed, in accordance with the Department of Fisheries and Oceans as well as other environmental governing agencies. The project, initiated by the City of Edmonton and in cooperation with Park Paving Ltd., was designed by Clearflow Enviro Systems Group Inc. as a pilot project to reduce NTU values and demonstrate the effectiveness of the Water Lynx blocks.
