It followed two Government stimulus packages worth €87 million, allowing Irish Water to undertake more projects.

Irish Water, in partnership with Kerry County Council, replaced an additional 2.9 kilometres of water mains in Listowel, Kilfenora and Ballymalis.
Pressure management works were carried out in Tralee, Killarney, Castlemaine and Ballybunion, which will help improve water quality and reduce high levels of leakage.
