Make sure you can meet your authorisation conditions
- Arrange installation of any pre-treatment fixtures or plumbing modifications that are needed. A licensed plumber must do all these works.
- Take any other actions to make sure you can meet your authorisation conditions before you start to discharge waste into the sewer.
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. Inspections are annual for most customers – more frequent where high risk activities occur – and there is a fee for each inspection.
Once-off discharges
Once-off trade waste collections are classified as liquid hauled waste. See the liquid hauled waste pages for more information.
