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 on the Monread Road, Naas?
Irish Water is working in partnership with Kildare County Council to upgrade and replace the sewers in several locations in Naas. To minimise disruption, the work will be completed in phases and traffic management will be in place.
As part of the next phase of works, a phased road closure will be required on sections of the Monread Road, Naas, to facilitate the installation of essential wastewater infrastructure. It is proposed that these works take place from 28 June through to August 2021, across three phases:
- Phase 1: 28 June – 12 July 2021
- Phase 2: 12 July – 2 August 2021
- Phase 3: 2 August – 9 August 2021
Please see the below maps for further information on the proposed traffic management plans.
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. Diversion routes will be clearly signposted, as agreed with Kildare County Council and An Garda Síochána.
We apologise in advance for any inconvenience caused during these essential works.
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.
