Most commercial and industrial businesses require pre-treatment before their wastewater can enter the sewerage system.
Managing trade waste
What is trade waste?
Trade waste is all non-human liquid waste generated on commercial properties that’s discharged to our sewerage system. It includes liquid waste such as grease, oils and chemicals.
If you own a business that generates trade waste you will need some form of pre-treatment and a trade waste permit. See below for more information.
Have you purchased a new business?
If you have purchased a new business that you think may generate trade waste, we recommend purchasing a Trade Waste Search which will inform you of any existing trade waste activity on a property.
Why do we manage trade waste?
Trade waste from businesses can:
- Create hazardous gases such as hydrogen sulfide and methane which is a safety hazard for those working in and around the sewerage system.
- Damage sewerage infrastructure as hydrogen sulfide is corrosive.
- Cause blockages and 'fatbergs' in the sewerage network from the oils, grease and solids.
- Upset the treatment process and damage pumps.
- Pollute the environment and waterways if untreated.
- Impact downstream recycling of water and reuse of biosolids.
