NO DISRUPTION WITH NO-DIG

This article shows how Strathclyde Regional Council, Scotland's no-dig methods for replacing old lead water pipes under roads can offer large savings in time and money. The pipes need to be removed quickly because they are quite a serious environmental health hazard. No-dig methods have the following advantages: (1) they are about twice as quick as conventional open cut methods; (2) their direct money cost is not much more; (3) they avoid disruption to traffic, other road users and local inhabitants; (4) they do not involve repeated disturbance to road surfaces; (5) they minimise the risk of interference with other underground utilities like gas and electricity. Strathclyde's no-dig programme has been subject to close monitoring by its engineers since its introduction on a trial basis in 1983. Monitoring has revealed savings which suggest that no-dig can achieve almost twice as many pipe renewals for the same expenditure as conventional trenching. Development of suitable equipment should reduce the cost of no-dig still more. The chief problem in its introduction to Strathclyde seems to have been the opposition of supervisors and workmen to the new techniques.
