Trade Effluent is any liquid waste that is discharged into our public sewers from a business or an industrial process and this is governed by the Water Industry Act 1991. Anything that isn't domestic sewage (normal household wastewater), uncontaminated surface water and rainwater run-off is classified as trade effluent. 

Wastewater analysis in the form of discharge consents, especially related to trade effluent testing, are one of the most common forms of analytical requirement placed across all industries. A discharge consent is a legal document issued by your local water authority and this will contain a number of conditions, including those that control the quality and quantity of the discharge produced.
