The Trade Waste Management System (TWMS) provides a framework for the administration, acceptance and regulation of the disposal of trade waste to the sewerage system.
Under the TWMS, a business that discharges trade waste to sewer will need to apply for approval to discharge trade waste.
Your business must also follow the conditions of the Trade Waste Code.
Before you apply
You will need to consider:
- how stormwater runoff will be managed
- what types of contaminants exist on-site
- what business processes and activities generate waste
- how you can limit the amount of trade waste generated
- which kinds of proprietary products and chemicals will be used on site
- if you need to provide Safety Data Sheets (SDS)
- your discharge volumes and flow rates.
How to apply
If you are a food business you can apply for:
- approval to discharge trade waste to sewerage
- variation to a current approval
- to renew your discharge licence.
