HC Deb 02 July 1957 vol 572 c99W
Mr. J. Taylor

asked the Secretary of State for Scotland how many local authorities in Scotland discharge raw sewage into the sea, lochs and estuaries; how many so discharge partially treated sewage; and which authorities dispose of sewage in these ways.

Mr. Maclay

I regret that the detailed information asked for is not available. It is estimated, however, that sewerage systems serving about one-third of the population of Scotland are at present discharging raw sewage; the discharges of raw sewage are mainly to tidal waters.
