When we discuss trade effluent, we are referring to polluted liquid waste and not solid waste.
This is not surface water or domestic sewage. Oils, grease, chemicals, food waste, soil, detergents, and other substances can contaminate trade effluent.
If your business is discharging this type of waste into the sewage system, you have a legal obligation to declare it. Sewer effluent requires a more severe treatment process, which is why businesses must secure legal consent. The aim is to prevent this waste entering our rivers, lakes and oceans and causing severe water pollution issues.
