HC Deb 13 October 1976 vol 917 cc117-9W
Mr. Greville Janner

asked the Secretary of State for the Environment what further steps he proposes to take to deal with Great Britain's water shortage.

Mr. Denis Howell

The recent rainfall together with the measures which the Government and the water authorities have already taken should ensure adequate supplies for the remainder of this year provided that water savings are maintained. As regards next year's supplies I hope to make a statement shortly on the Government's conclusions on the Winter Drought Study prepared by the National Water Council.

Mr. Greville Janner

asked the Secretary of State for the Environment what effect the high rainfall during recent weeks has had on the United Kingdom's drought condition.

Mr. Denis Howell

The rainfall of recent weeks has substantially increased the stocks of water in water authorities' and water companies' impounding reservoirs in England and Wales. In some cases stocks are well above average for the time of year. Most underground water levels, however, are still below the seasonal average.

The general improvement has enabled many of the restrictions imposed on the availability and use of water to be lifted.

Mr. Greville Janner

asked the Secretary of State for the Environment what is the state of Great Britain's water reserves; and how these compare with those in each of the previous five years.

Mr. Denis Howell

It is not practicable to express Great Britain's water resources quantitatively because a large part is represented by underground water which cannot be reliably measured.

Impounded water stocks have been substantially increased by recent rainfall, but underground water resources, which are replenished mainly by winter rainfall, have benefited only moderately so far.

Mr. Greville Janner

asked the Secretary of State for the Environment what were the amounts of rainfall in the month of September in each of the water board areas; and how these compare with rainfall in previous years.

Mr. Denis Howell

The information is not immediately available by water
