Liquid trade waste is liquid waste produced by a commercial business or industrial activity (excluding sewage).
The correct disposal of liquid trade waste is important to maintain effectiveness of the sewerage treatment process, to maintain the sewer network and for the health of the local environment. Any business who wishes to discharge liquid waste into the sewer network must have permission to do so based on their liquid waste classification.
