Management practices to safely dispose of generated wastewater

  • Ensure adequate housekeeping practices are in place and diligently adhered to. 
  • Check all transloading stations and equipment to avoid any unintentional releases. 
  • Locate all nearby storm drains to prevent accidental spills into the storm system. 
  • Install all proper pre-treatment systems prior to any discharge point.

Frequently asked questions about pre-treatment options

What do I need to install?

You need to install a system to remove or capture any solids, fluids or chemicals released from your business, to prevent unwanted substances from going into wastewater or the environment. This system is often referred to as ‘pre-treatment’.

Who can do installation?

Pre-treatment selection and installation must be completed by a qualified/certified consultant or tradesperson.

Who cleans its?

A qualified service provider can assist with this requirement, as well as tools to help manage cleaning needs and offer proper disposal of waste material.

How to dispose of 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 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 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).
