Irish Water plan to undertake the upgrade of the existing Tubbercurry, Grange, Strandhill and Ballinafad wastewater treatment plants (WwTP) and the Strandhill Pumping Station. Other works include the construction of a new combined sewer overflow (CSO) diversion and outfall discharge pipelines in Tubbercurry and associated ancillary works. There will also be a 2 year operational period and it is intended that the works will be implemented under a Design, Build and Operate (“DBO”) Contract.
