This Cork-based project included constructing a new 80,000 pe wastewater treatment plant (WwTP) and 15 new pumping stations, upgrading four existing pumping stations (about 30 km of new sewer) and rehabilitating existing sewers and a drilled crossing under the Lee estuary.

This project has significantly enhanced the water quality within Cork Harbour through enhanced wastewater treatment with a new WwTP at Shanbally. The project has ensured compliance with the Urban Waste Water Treatment Directive and protected several important European designated habitats and species.

Operations began at the new WwTP at the end of December 2016. The project was completed in 2021, and wastewater from the agglomerations of Ringaskiddy–Crosshaven–Carrigaline, Ringaskiddy village, Passage–Monkstown and Cobh town is now no longer discharged into Cork Harbour.

Completing the project will support economic growth and development in the area, increasing the potential for tourism and recreational activities and enhancing the amenity value of Cork Harbour.

The project was awarded Project of the Year at the 2022 Association of Consulting Engineers of Ireland Engineering Excellence Awards.
