HC Deb 04 July 1983 vol 45 c18W
Sir Brandon Rhys Williams

asked the Secretary of State for Wales if he will require the Welsh water authority to publish figures indicating the revenue cost and the full cost of effluent treatment per unit of volume at each of their works serving areas with a population of 5,000 or more; and if he will publish a table collating such information as is available.

Mr. Wyn Roberts

I understand that the Welsh water authority does not produce such information in respect of individual sewage treatment works, of which it has 64 in the category mentioned. I am advised that comparisons between works cannot be made on the basis of costs alone, because of differences in the treatment required and other operational factors.
