The following Environment practice note produced in partnership with John Bates of Old Square Chambers provides comprehensive and up to date legal information covering:

  • Sewage disposal—regulation of sewage disposal works
  • Brexit impact
  • Construction of sewage disposal works
  • Environmental permits
  • Odour from sewage disposal works

Under s 94(1)(b) of the Water Industry Act 1991 (WIA 1991) a sewerage undertaker has a duty to deal with the contents of its sewers, whether by means of sewage disposal works or otherwise.

Sewage disposal works are works used for receiving, storing, treating and distributing or otherwise disposing of sewage contained in sewers.

Brexit impact

11 pm (GMT) on 31 December 2020 marks the end of the Brexit transition/implementation period entered into following the UK’s withdrawal from the EU. At this point in time (referred to in UK law as ‘IP completion day’), key transitional arrangements come to an end and significant changes begin to take effect across the UK’s legal regime. Any changes relevant to this content will be set out below.

For further guidance, see Practice Note: Brexit—impact on environmental law and News Analysis: Brexit Bulletin—key updates, research tips and resources.

Construction of sewage disposal works

A sewerage undertaker has the power to construct new sewage disposal works as a consequence of its appointment to be such an undertaker.

The construction of a waste water treatment plant will be a project of national significance only if the plant, when constructed in England is expected to have a capacity exceeding a population equivalent of 500,000. The alteration of such a plant in England will be nationally significant if the effect of the alteration is expected to increase its capacity
