If you run a business that disposes trade waste, there are a number of things you need to know and do before you can get rid of it.

Trade waste, or industrial wastewater, is any wastewater discharged from your business other than waste from office facilities or staff amenities.

Industrial wastewater disposal

Industrial wastewater can come from a number of industries, including energy production industries, hospital and aged care homes, mineral processing, recycling works, vehicle and plant servicing, food processing and more.

If you're disposing industrial wastewater to the sewer system, you need to ensure you have a trade waste permit because not all wastes are suitable for our system.

Industrial wastewater includes process waters, wash-down water, contaminated storm water and cooling water.


All businesses discharging industrial wastewater to our sewerage system require a trade waste permit. We'll assess your application and explain further steps to ensure your trade waste is safely disposed.
