HC Deb 27 June 1989 vol 155 c383W
Dr. Cunningham

To ask the Secretary of State for the Environment if he will list the number of private drinking water supplies in England and Wales and the number of people served by those supplies.

Mr. Howard

Local authorities collect and hold information on private supplies in their respective areas. Precise information is not held centrally. However, we estimate that there are 80,000 to 100,000 private supplies in the country serving approximately 1 per cent. of the population.
