Trade Waste

Information regarding TasWater's trade waste helpline can be found here.

What is trade waste?

Trade waste is any liquid waste or substance discharged into the sewerage system from a business premise other than normal domestic sewage. Only trade wastewater which complies with specific guidelines may be discharged into the sewerage system. All companies and businesses operating in Tasmania that are discharging trade wastewater into the sewerage system need to be aware of our trade wastewater requirements.

Why manage trade waste?

TasWater’s sewerage network is designed for the transport and treatment of liquid waste from typical household activities. When untreated trade waste enters our network it damages pipes and causes blockages and spills. It also disrupts the sewage treatment process, damages the environment and presents a safety risk to the public, TasWater staff and contractors – particularly in the case of flammable chemicals. TasWater also has a legal obligation to minimise the impact of sewage on the environment. One of the ways we do this is by requiring our trade waste customers to install compliant pre-treatment systems to reduce the amount of unwanted substances entering our sewerage network for treatment.
