Clear water waste

Clear water waste

Disposal of clear water waste into Calgary's wastewater system, including a manhole or monitoring access point, is prohibited without prior approval from the Director, Water Services.

Clear water waste disposal to wastewater system

If you are disposing of water from sources other than wastewater streams, including the following:

  • Roof and foundation
  • Remediated groundwater
  • Accumulated storm drainage or groundwater
  • Non-contact cooling water
  • A disposal as directed by Alberta Environment

Use the Nuisance Water Disposal Flowchart to determine if you require disposal into the wastewater system.

If your project qualifies you for wastewater system disposal, first determine if it is foundation drainage connected to The City's wastewater system before 1973.

If not, you may need to apply for a Clear Water Waste Disposal Permit.

All wastewater must comply with substances listed in Schedules A, B, and C of the Wastewater Bylaw.

Application checklist:

  • Have you completed the Clear Water Waste Disposal Permit Application form in full?
  • Have you included the justification to dispose to the wastewater system using the Nuisance Water Disposal Flowchart?
  • Have you included a description of the project?
  • Have you included a description of the pre-treatment system?
  • If you wish to discharge at a rate greater than 150L/min, have you included the proposed rate?
  • Have you included water quality results? (Water quality results must be reported using the Analytical Results Reporting Form.)
  • If water quality results cannot be obtained at this time, have you included justification as to why they are being deferred, and when they will be available? 

Please contact 311 if you have further questions/concerns. Let the operator know you are looking for information regarding the Industrial Monitoring Group's Clear Water Waste Disposal Program.

If you are collecting, treating and disposing wastewater in a privately-owned system, such as a septic tank with an absorption field, a private wastewater system application is required.

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).
