Commercial painting

Commercial painting

Commercial painting facilities must adhere to Wastewater Bylaw 14M2012 and Stormwater Bylaw 37M2005. For detailed information refer to our Commercial painting industry wastewater compliance handout.

Considerations for wastewater disposal

  • It is prohibited to discharge paint waste or wastewater into the stormwater system.
  • Solids must be diverted to a solids waste stream unless the materials are considered hazardous, in which case they shall be sent to an appropriate treatment facility.
  • Visit calgary.ca/hhw or contact 311 for the hazardous materials disposal requirements.

Management practices to safely dispose of generated wastewater

Latex and water-based paints

  • Unused paint must be disposed of at a paint waste drop-off facility and cannot be discharged into the wastewater or stormwater system or in the garbage.
  • Wash water used to clean brushes can do down a drain connected to the wastewater system.
  • Dried paint and empty paint cans can be disposed of a designated firehall or City landfill Throw ‘n’ Go area.

Oil-based paint

  • Unused paint must be disposed of at a paint waste drop-off facility and cannot be discharged into the wastewater or stormwater system or in the garbage.
  • Paint thinner and oil-based paint waste cannot be disposed of in the garbage or discharged into the wastewater or stormwater system. 

How to dispose of commercial paint

The East Calgary Landfill accepts commercial paint at one of two locations within the landfill, depending on the quantity. Smaller quantities are placed at the Throw ‘N’ Go area. Large quantities are placed at the paint transfer station. Commercial paint businesses are responsible for appropriate packaging and unloading of all materials.

What to do if you have an unintentional release

In the event of an unintentional release, it is important to act quickly to prevent the material from entering the wastewater or stormwater system. You should notify:

  • 911
  • The City of Calgary by contacting 311.
  • The owner of the premise where the release occurred.
  • Any other person that may be affected by the release.

For any spills that could harm the environment you will also need to report the spill to Alberta Environment & Protected Areas (1-800-222-6514).
