Trade waste

What is trade waste?

Trade waste is the waste water from any industry, business, trades or manufacturing premises. Trade waste does not include:

  • waste that is a prohibited substance or stormwater
  • domestic wastes of human origin (sewage) which are allowed, without permit, to be discharged to the sewerage system.

The overall objective of the Trade Waste Program is to control the discharge of trade waste into the sewerage system, and provide for the collection and treatment of commercial and industrial sewerable liquid waste, in an environmentally responsible way. Our Trade Waste Environmental Management Plan sets out how we are going to achieve this.

Who has trade waste?

There is a misconception that trade waste is toxic and is only generated by industry or factories. Trade waste includes wastewater discharges from commercial businesses such as:

  • food outlets
  • laundromats
  • service stations
  • vehicle repair workshops
  • equipment hire centres
  • printers
  • and many more.

Trade waste can include limited amounts of substances like grease, oils and solids.

The trade waste program brochure outlines the common industrial and commercial processes that discharge trade waste and provides a guide to the associated pre-treatment requirements.

If your business generates waste water that is not toilet waste or household waste, you must hold a permit to discharge the trade waste into our sewer. Applications forms for pemits are available below.
