§ Mr. G. Johnson Smith
asked the Secretary of State for Scotland what is the present volume of supply and demand for water in Scotland, and the estimated 232W supply and demand in the years 1970, 1975 and 1980.
§ Mr. Ross
Available public supplies at present amount to about 410 million gallons daily against a demand of 380 m.g.d. Estimated demand is expected to rise to 430 m.g.d. by 1970, to 470 m.g.d. by 1975 and to 510 m.g.d. by 1980. It is not possible to estimate what the available supplies will be in these years since this depends on the progress in developing new sources.
