Trade waste is any used water and substances from commercial, industrial, business trade or manufacturing activities that are discharged to our sewerage system for removal and treatment. We accept trade waste into our sewers wherever possible, but to discharge trade waste, you must have authorisation and comply with the authorisation conditions.

Liquid hauled waste is used water from industrial, commercial or domestic customers who are not connected to the sewerage network. It may also include some wastes not deemed appropriate for discharge to the sewerage network. This used water is delivered to one of our septic waste disposal stations by an approved liquid waste hauler.
One-off trade waste disposals also come under this category.
