| Abstract | This paper describes the methodology and results of implementing four 'no-dig' or trenchless techniques in selected areas of Selangor, Malaysia, as part of the Pilot Pipeline Rehabilitation Project. The techniques used were: (1) pipe bursting or replacement moling; (2) ambient sewage lining; (3) slip lining; and (4) scraping and cement mortar lining. The first three techniques were used to insert medium-density polyethylene (MDPE) pipes into existing asbestos cement pipes. The fourth technique involved lining cast iron mains with cement mortar. An analysis of the cost of traffic delays caused by traditional open-trench excavations revealed that 'no-dig' techniques offered cost savings of up to 65 per cent in the short term, when foreign specialists are required, and 72 per cent in the long term when the technology has been transferred to local staff. |
