Trade Effluent

If your business plans to discharge trade effluent into any public foul sewer within our supply area, you must get our permission before any discharges take place.

This is a legal requirement under the Water Industry Act 1991. Trade effluent can be best described as anything other than domestic sewage (toilet, bath or sink waste) or uncontaminated surface water and roof drainage (rainwater).
