Environmental risks of concrete, asphalt, and cement-based products
Concrete, asphalt and cement based products are harmful to our environment and may cause adverse effects on fish, insects and plants. The chemical content of these wastes are classified as hazardous by Alberta Environment and may have increased concentrations of hydrocarbons and heavy metals. In addition, there is potential for obstructions in the EPCOR drainage system.
Waste from these materials have a high potential of entering the stormwater drainage system through catchbasins which lead directly to local creeks, stormwater management facilities and the North Saskatchewan River. These products are prohibited substances in the
City of Edmonton EPCOR Drainage Services and Wastewater Treatment Bylaw 19627.
- Concrete wastewater cannot be adequately filtered to reduce its toxicity
- Filtered wastewater that looks clear still has a high level of toxicity
- You are responsible for proper disposal of concrete, asphalt and cement and are required to have a plan in place to manage wastewater runoff before you start work.
Concrete, asphalt and cement cannot, at any time, be allowed to enter the drainage system. Report any spill immediately to EPCOR by calling
