The defendant sewerage undertaker received sewage, treated it in filter beds and discharged the treated liquid into the river. One night someone unlawfully discharged a solvent called iso-octanol into the sewer. It passed through the sewage works and entered the river. The question was whether the defendant had caused the consequent pollution.
Held: The defence to a pollution charge is wider than that for a breach of licence condition. The statutory defence to a breach of consent also applies to the allegation of causing pollution. The word ’cause’ in the subsection should be used in its ordinary sense and ‘it is not right as a matter of law to add further requirements.’ and ‘Yorkshire Water Services having set up a system for gathering effluent into their sewers and thence into their sewerage works there to be treated, with an arrangement deliberately intended to carry the results of that treatment into controlled waters, the special circumstances surrounding the entry of iso-octanol into their sewers and works does not preclude the conclusion that Yorkshire Water Services caused the resulting poisonous, noxious and polluting matter to enter the controlled waters, notwithstanding that the constitution of the effluent so entering was affected by the presence of iso-octanol.’
