Trade Waste Application

Trade Waste Application

Trade waste authorisation process

All customers are required to have a trade waste discharge authorisation before discharging any trade waste to sewer.
The trade waste discharge authorisation details the conditions you need to meet before you discharge to the sewer.
We will work with you to review and verify the suitability of the pre-treatment system. We will visit your premises to inspect your discharge and to work with you by providing advice and support. Together we can ensure you meet your ongoing authorisation conditions.

Where the installation meets our full requirements, your trade waste discharge authorisation will be provided or extended. If the pre-treatment installation does not meet your requirements, amendments or maintenance will need to be made to the pre-treatment system before trade waste discharge authorisation is provided or extended. We keep copies of trade waste discharge authorisations as required under the Water Industry Act 2012.
