Trade waste is any liquid that is discharged into Council's sewerage system as the result of any trade or industrial process.

There is a growing awareness that careful disposal of this type of waste is important to protect the environment and the health of the community.

Trade waste disposal is controlled by a bylaw to ensure safe disposal and to protect the sewerage system and treatment plants, which are essential city assets.

Assessment of trade waste charges

Most of the wastewater for treatment is domestic in nature but some industries can produce wastes that take up a significant portion of our treatment facilities.

We assess the wastes that are generated by commercial processes and calculate the treatment costs so that they are shared equitably between domestic and commercial users.

This cost is broken down into four categories:

  • volume
  • nutrients in the form of Nitrogen
  • chemical complexity
  • solids.

Where the trade waste volumes or strengths discharged are of a low level, no charges are made beyond those already recovered through property rates.

Charges specific to trade waste can be found in our fees and charges document under the Drainage heading. Follow the link below for details.

Grease traps

Commercial food premises and food preparation industries are required to have grease traps installed. They pre-treat the waste before it enters the treatment system (either Council's sewer line or a private septic tank).
