Businesses are required to obtain trade effluent consent if they discharge trade effluent into public sewers or if they dispose of contaminated liquid waste (non-domestic) into sinks or toilets. Surface water run-off from contaminated surfaces being discharged into public sewers also requires trade effluent consent.
It is important to note that even if your trade effluent discharge is expected to be temporary, such as during construction works, you are still required to arrange for trade effluent consent.
If there are any changes to your trade effluent, such as changes in volume or composition, it is crucial to inform your water supplier promptly. This ensures that a new consent framework can be established, preventing any potential penalties or fines.
