HC Deb 06 February 1989 vol 146 cc528-9W
Mr. Boswell

To ask the Secretary of State for the Environment what proportion of all domestic properties are served by(a) sewers adopted under section 18 of the Public Health Act 1936, (b) sewers connected to the mains but themselves unadopted and (c) private sewers unconnected to the mains; and what proportion of new houses fall into these several categories.

Mr. Howard

More than 95 per cent. of the population of England and Wales are connected directly or indirectly to the public sewer network. No comprehensive information is available on the proportion of domestic properties served by sewers adopted by water authorities under sections 17 and 18 of the Public Health Act 1936, or which remain unadopted.
