Irish Water proposes to replace the existing 450 mm diameter cast-iron water main between Shanakiel Reservoir and Popes Quay with a new 600 mm diameter trunk water main, in order to increase its hydraulic capacity and performance and increase security of supply to the city centre. In conjunction with the proposed trunk main replacement, Irish Water proposes to replace selected elements of the existing distribution network that are in poor condition and/or exhibit poor performance.2.4 km of 600 mm diameter trunk water main between Mulgrave Road and Shanakiel Reservoir, including all valves, fittings and connections; 300 m of 150 mm diameter distribution water main at the North Mall including all valves, fittings, mains tie-ins and water service connections.
Irish Water proposes to lay a 600 mm diameter trunk water main between the Cork Harbour and City Water Supply Scheme (WSS) at Curraheen and the Lee Road Water Treatment Plant (WTP) which supplies the Cork City WSS. This trunk main will provide a strategic link between the two water supplies to ensure security of supply and also reduce the current demand on the Lee Road WTP.
