HC Deb 13 January 1994 vol 235 c243W
Mr. Gordon Prentice

To ask the Secretary of State for the Environment how many miles of water mains are planned to be replaced by each of the water companies in England in 1994 because of poor water quality.

Mr. Atkins

The length of water mains which water companies plan to replace for water quality reasons in England during 1994 is estimated to be 1,100 miles. In addition, companies plan to reline approximately 1,380 miles. Replacement or relining may be carried out for reasons other than improvement in water quality, such as the structural condition of mains and to improve water pressure; replacement for those reasons usually also results in an improvement in water quality.
