Upper Liffey Valley Sewerage Scheme
Irish Water is expanding and upgrading the sewerage system in communities across Kildare.
Wastewater from the area is sent to a wastewater treatment plant at Osberstown for treatment. The Osberstown plant has already been upgraded to increase capacity, and to ensure that wastewater is treated to meet the requirements of European regulations.
We are now working on the next stage of the scheme, upgrading the sewer network. These upgrades will ensure the network has enough capacity for future growth, and will reduce the risk of overflows during storms. We are working in several locations across Kildare, including Sallins, Clane, Prosperous, Naas, Johnstown, Kill, Newbridge, Kilcullen, Athgarvan, Carragh and the Curragh.
