Nereda strengthens its presence in Ireland as integral part of major Drainage Project programme. Cork Lower Harbour WWTP is a large natural harbour which is located in the estuary mouth of the River Lee, in County Cork, the largest and most southern county in Ireland.


Before the extensive upgrade, untreated sewage from Cobh, Carrigaline (including Crosshaven), Passage West/Monkstown (including Glenbrook) and Ringaskiddy (including Shanbally and Coolmore) was discharged into Cork Lower Harbour on a daily basis. By providing enhanced wastewater treatment, the new project provides environmental protection, which will facilitate economic growth in the Lower Harbour area and provide for a growing population.


Irish Water, Ireland’s national utility responsible for providing and developing water and wastewater services throughout Ireland, carried out this project on a new wastewater treatment plant in Shanbally as part of the Cork Lower Harbour Main Drainage Project. Irish Water is making an overall investment of €91 million into the €135 million project, which is eliminating the discharge of untreated sewage into the Lower Harbour. The project was a massive undertaking, with the new state-of-the-art wastewater treatment plant at Shanbally complementing 14 new pumping stations, 30km of new sewers, repair work on existing sewers and a drilled crossing under the estuary. The Cork Lower Harbour Main Drainage Project aimed to provide enhanced wastewater treatment, through the development of a new wastewater treatment plant at Shanbally County Cork. The Project is important in terms of protecting the environment, facilitating economic development and providing for a growing population (population equivalent of 72,000).


Commenting on the project, Déaglán Healy, Project Manager at Irish Water said, "Our priority is to develop infrastructure capable of providing quality wastewater services across the country.” The development of a new Wastewater Treatment Plant has improved wastewater treatment for the communities around Lower Harbour. A sustainable Wastewater Treatment Plant brings health and environmental benefits to the growing local population, as well as improved water quality for all who enjoy the wonderful natural resource. The WWTP started treating sewage in late 2016, with immediate tangible benefits to the Lower Harbour.
