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.
The sewer network will have more capacity, which will facilitate future growth and economic development
Treated wastewater will be cleaner and will meet all regulatory requirements, which will help Ireland avoid substantial EU penalties
The number of emergency overflows to the River Liffey will be significantly reduced
There will be a reduced risk of flooding in Naas
Significant upgrades to the Osberstown wastewater treatment plant (now complete).
28Km of new gravity sewers and rising mains to reinforce and improve the existing network.
6 new or upgraded pumping stations, all with stormwater storage tanks to reduce the risk of emergency overflows.
What is happening now?
As part of the next phase of works, Irish Water will be upgrading the sewer network in Sallins town centre. The works are due to commence on Monday, 10 January 2022 and are expected to be completed by early March 2022.
The works will be carried out in phases to minimise the impact to local businesses and residents. While no through traffic is possible during these necessary works pedestrian access will be maintained at all times in all directions of the works and local access via selected routes will be maintained for deliveries.

It is planned that works will commence on Monday, 10 January 2022, in the green area adjacent to Naas Lower Lake off Craddockstown Road. In order to carry out the works safely, the public walkway that runs parallel to the lake will be closed for the duration of the works, we apologise for any inconvenience this may cause. Irish Water expects these works to last at this location for approximately 6 weeks. To facilitate these works a Stop/Go System will be in place throughout the works period.
Irish Water are continuing to engage with residents and businesses in the local area in order to minimise disruption. Our community liaison officer is available to take any queries on 086 387 7875.
