Carpet cleaning

Carpet cleaning

Carpet cleaning businesses must adhere to Wastewater Bylaw 14M2012 and Stormwater Bylaw 37M2005. For detailed information refer to our Carpet cleaning industry wastewater compliance handout.

Manage contaminants in your wastewater

  • Ensure the purchase of non-toxic detergents and cleaners.
  • Prior to cleaning, confirm equipment is in proper working order, free of leaks and damage.

Using a pre-treatment method

  • Filter screens shall be installed at any water release point to capture all solid materials.
  • Dry vacuuming should occur prior to cleaning agent application and water cleaning.
  • 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.

How to dispose of your wastewater

Drains connected to the Wastewater System (i.e. floor drains and sinks) may be used to dispose of wastewater if the following conditions of the Wastewater Bylaw (14M2012) are met:

  • Does not contain any substances listed in Schedule A Prohibited Substances;
  • Does not exceed any concentrations listed in Schedule B Restricted Substances and Schedule C Surcharge Substances.

If the wastewater exceeds City of Calgary Wastewater Bylaw limits, the wastewater can be disposed of at other waste treatment facilities where industrial wastewater is permitted.

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).
