- Upper Liffey Valley Sewerage Scheme & Osberstown Wastewater Treatment Plant Upgrade
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.
Benefits
- 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
Steps
- 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 in Sallins?
Irish Water is working in partnership with Kildare County Council to upgrade and replace the sewers in several locations in Sallins. To minimise disruption, the work will be completed in phases and traffic will be managed through stop/go systems.
- We have begun work on the construction of approximately 700m of new main sewers in the Castlefen and Castlesize estates.
- We plan to install over 650m of new sewer along Millbank and the R407 Clane Road, north of the Canal. This new interceptor sewer will serve Sallins town centre.
