Trade waste is any wastewater discharged from your business other than wastewater from office facilities or staff amenities.

Trade waste is produced by a number of industries, including retail food such as cafes and restaurants, vehicle or plant servicing, and other commercial and industrial businesses.

If you run a business that disposes trade waste, there are a number of things you need to know and do before this can occur.

Not all trade waste is suitable for disposal into our wastewater sewer system and before you discharge, you need to ensure you have a trade waste permit.


All businesses discharging trade waste to our wastewater sewer system are required to apply for approval. We'll assess your application and explain our requirements and conditions to ensure your trade waste can be accepted.
