Trade Waste

Trade Waste

Trade waste is water that has been used in a business activity. It may not be just sewage. Trade waste often has other substances in it too, like solids or chemicals. Most often, trade waste is created in industrial or manufacturing businesses.

We accept trade waste into our sewers wherever possible. But, we can only do that if you have a trade waste discharge authorisation and comply with its conditions.

This is needed by law, under Section 56 of the Water Industry Act 2012.

Our Restricted Wastewater Acceptance Framework tells you more about how we manage trade waste. It also includes information about authorisation compliance.

For information about contaminant concentrations, read the Restricted Wastewater Acceptance Standards [PDF, 400 kB]. The standards also contain detail about other water characteristics we accept in our sewerage system.

What do I do if I only need a once-off trade waste disposal?

For one-off disposal, please visit the Liquid Hauled Waste section of our website.

How can I apply for an authorisation?

For all the information you need and how the application process works, go to Authorisations for Trade Waste Discharge.
