HC Deb 20 October 1976 vol 917 cc461-2W
Mr. Holland

asked the Secretary of State for the Environment how water stocks in England and Wales at the latest date for which figures are available compare with the stocks 12 months and 24 months previously.

Mr. Denis Howell

An important proportion of the water supplied in England and Wales is derived from underground sources, the full potentials of which cannot be assessed with certainty, and there are accordingly no overall figures of water stocks.
