Trade waste

Watercare’s trade waste team works to ensure that industrial liquid waste is safe for discharge into Auckland’s wastewater system for treatment.

Any customer that discharges liquid into Auckland’s wastewater system from any business, industrial or trade process is considered a trade waste customer. 

Our trade waste team monitors this activity and works with these customers to ensure they adhere to the conditions set out in the Auckland Trade Waste Bylaw 2013, the region-wide standard for the management, regulation and risk classification of trade waste.

A combination of the bylaw and Trade Waste Agreements limit the discharge of potentially harmful substances and help us protect Auckland’s wastewater system and the environment.
