Carrickmacross Sewerage Scheme – Contract No 1 – Pipelines

This project consisted of constructing in excess of 30km of foul and surface water sewers (225-900mm in diameter), 3km of rising mains (100-400mm diameter), 6 pumping stations and the replacement of 7.5km of watermains in the town centre, as well as extensive rehabilitation works to the existing network and the abandonment of several existing Combined Sewer Overflows (CSOs). 500No. manholes and 10 No. outfalls were also constructed. Particular difficulties encountered included pipelaying in narrow streets, peat and soft ground conditions, road traffic management, overpumping and non-negligence insurance issues.
