Understanding what's required
Typically, trade waste must be pre-treated in readiness for discharge to our sewerage system. It is your responsibility and a requirement of your trade waste consent to install appropriate treatment equipment for your business.
Before installing pre-treatment equipment you may wish to discuss pre-treatment requirements with our trade waste team or engage a specialist consultant to design a system accordingly.
Once you've submitted a trade waste application, you'll receive a consent which outlines the maintenance and sizing requirements of relevant equipment required to safely dispose of trade waste.
Prior to connecting any treatment apparatus to the sewerage system, a plumbing application must be lodged through PropertyConnect and consent received from our development branch.Visit PropertyConnect to apply.
Specific pre-treatment apparatus MUST be installed in accordance with the minimum requirements set out in our guidelines and standard drawings below.
