Trade waste any is liquid waste, other than domestic sewage, that is generally generated by industrial and commercial business activities that is discharged into the sewerage system.
This discharge into the sewerage system is only permitted with Western Water's consent and it is closely monitored to minimise any adverse impact. Western Water also monitors trade waste to protect the quality of our recycled water and biosolids for reuse.
Western Water currently has greater than 400 trade waste customers with close to half operating food service businesses including cafes, restaurants, bakeries and takeaways.
All trade waste customers are inspected at least once a year or as required.
Western Water’s Trade Waste By-Law, made pursuant to The Water Act 1989, provides Western Water with the legal power to regulate or prohibit the discharge of trade waste.
Applying to Discharge Trade Waste
Applicants will need to develop a Trade Waste Management Plan and submit a Trade Waste Application Form prior to the discharge of trade or septic waste. Western Water has the right to refuse to enter into any agreement.
When you submit your application form you must also supply:
- Layout plans of areas used in the generation and transport of trade waste or septic waste.
- Plans of equipment and details of processes which are to be used for the treatment of the trade waste before it enters the sewerage system.
- Plans and details of all pipes, floor channels and drains used to convey the trade waste from the source of discharge to any apparatus used for treatment of the trade waste.
- Details of the method of measuring the total volume of trade waste or septic waste to be discharged.
- Other information as required by Western Water.
Western Water necessarily limits the quality and other characteristics of trade waste it accepts into the sewerage system. The limits are known as “Trade Waste Acceptance Criteria” and any trade waste meeting these criteria will normally be suitable for discharge to the sewerage system.
