The court was asked: ‘whether a sewerage undertaker under the Water Industry Act 1991 has a statutory right to discharge surface water and treated effluent into private watercourses such as the Respondents’ canals without the consent of their owners.’
Held: The appeals of the sewerage company succeeded. Such discharges were in their nature a trespass, and could not be supported without statutory authority. Though the 1991 Act impliedly retained the rights for sewerage undertakers to discharge surface and other non-polluting water into private courses where they had already existed, such rights were not created withoutmore over new outfalls unless the owner of the private watercourse consented.
Lord Sumption said: ‘In my opinion, when the Water Industry Act 1991 (i) imposed on the privatised sewerage undertakers duties which it could perform only by continuing for a substantial period to discharge from existing outfalls into private watercourses, (ii) at the same time applied to them the statutory restrictions in section 116 on discontinuing the use of existing sewers, it implicitly authorised the continued use of existing sewers. A restriction on discontinuing the use of an existing sewer until an alternative has been constructed is not consistent with an obligation to discontinue its use forthwith under the law of tort. The inescapable inference is that although there is no provision of the Act of 1991 from which a general right of discharge into private watercourses can be implied, those rights of discharge which had already accrued in relation to existing outfalls under previous statutory regimes survived.’
Lord Neuberger said: ‘sewerage undertakers have the statutory right to discharge surface water and treated effluent into streams and canals (subject to payment of compensation for any damage thereby caused), but only in respect of outfalls in existence before the coming into force of the 1991 Act. I agree with the reasons given by Lord Sumption and Lord Toulson although I would place greater weight on the assistance which can be gained from the provisions of the earlier legislation relating to public sewers and the Interpretation Act 1978’
