Automotive

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

Why are these operations a concern?

Automotive service operations use many substances that can present risks to the wastewater and stormwater system. Individual facilities may contribute smaller quantities of these substances, but the collective impact from the automotive sector can be significant.

Pre-treatment systems such as oil-water separators, industrial sumps and interceptors must be properly maintained to avoid blockages, costly wastewater charges, fines and to ensure protection of the wastewater system and environment.

Substances of concern Sources
Hydrocarbons Fuels, oils, grease, solvents, flammable liquids and automotive fluids
Glycol Anti-freeze
Phosphorus Detergents, cleaners and exterior finishes
Metals and solids Rust, sand, sediment and paint chips

Pre-treatment options

Pre-treatment systems are a cost-effective way of preventing unwanted wastes from entering the wastewater system. If your business does not already have one, you will need to install a pre-treatment system that is designed and sized in accordance with the requirement of the National Plumbing Code of Canada to prevent hydrocarbons, flammable liquids and suspended solids from passing into the wastewater system.

Pre-treatment selection and installation must be completed by a qualified consultant or tradesperson. If you have any questions about the pre-treatment system selection or installation, contact PlumbingGasTAC@Calgary.ca or call 311.

For your pre-treatment system to be effective, it must be cleaned regularly and checked to ensure it is in proper working order. Most devices require cleaning when the last outflowing chamber is at 25 per cent settled solids capacity. You are required to complete and retain maintenance records on-site for a two-year period. See sample below. Your service provider can assist with the cleaning, maintenance record keeping, as well as the integrity of the pre-treatment system.

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).
