HC Deb 19 July 1995 vol 263 c1409W
36. Mr. Stephen

To ask the Secretary of State for the Environment what percentage of sewage treatment works failed their consent standards in 1986; and what is the equivalent figure now. [33409]

Mr. Clappison

In 1986, 23 per cent. of those sewage treatment works tested were non-compliant with their discharge consents. In 1993, the latest year for which data are available, the equivalent figure was 6 per cent.
