10. Mrs. Slaterasked the Minister of Housing and Local Government and Minister for Welsh Affairs what further research has been undertaken on the problem of gas liquor being processed by sewerage works.
§ Sir K. JosephResearch continues: a new large pilot plant is about to start work on the subject.
Mrs. SlaterDoes the hon. Gentleman know how long this research is likely to take, because in Stoke-on-Trent this is becoming a very real problem, and it will mean that the whole sewerage works may be put out of action by the amount of gas liquor which we have to turn into it?
§ Sir K. JosephI realise that this is locally a serious problem, but the hon. Lady must accept that it is a very difficult problem to solve. I will write to her, if I may, giving her the technical details.
