HC Deb 24 March 1981 vol 1 c284W
Mr. Wigley

asked the Secretary of State for Wales what was the total gallonage of water impounded in Welsh reservoirs and subsequently used in England in 1980.

Mr. Wyn Roberts

Figures for 1980 are not yet available. In 1979, 46,377 million gallons of water were supplied for use in England direct from impounding reservoirs in Wales. This figure does not include abstractions from rivers regulated by reservoirs in Wales.
