HL Deb 31 July 1985 vol 467 cc330-1WA
Lord Winstanley

asked Her Majesty's Government:

What lessons have been learnt from the experimental renovation of a sewer in Rochdale in 1982 and the Counters Creek sewer in Acton in 1984 by the "Ruswroe" process; and what opportunities are being provided for further study of this new method of relining old sewers.

Lord Skelmersdale

Appraisal of the "Ruswroe" and other sewer renovation systems is co-ordinated by the Water Research Centre. Details are not held centrally. I understand that, following an initial trial in Rochdale in 1982, a successful demonstration of the "Ruswroe" system was completed last year on the Counters Creek sewer. The WRC now consider that the "Ruswroe" system should be subjected to a monitored trial on a selected site and this is expected to commence later this year.
