Clane Wastewater Upgrade
Irish Water is upgrading the wastewater infrastructure in Clane as part of the Upper Liffey Valley Sewerage Scheme.
Sallins, Clane, Prosperous, Naas, Kill and Johnstown are served by a wastewater network which is no longer fit for purpose. This can cause overflows and flooding during storms. Irish Water is investing over €38 million to solve the problem and to provide additional capacity for future growth in these towns.
What is happening in Clane?
Irish Water is working in partnership with Kildare County Council to upgrade and replace the sewers in several locations in Clane. To minimise disruption, the work will be completed in phases and traffic management will be in place. Works in Clane include:
- Installation of over 500m of new gravity sewer from the L1023 Ballinagappa Road to the R403 and along Central Park. (Complete)
- Installation of approximately 400m of new gravity sewer on the Prosperous Road. (Complete)
- Installation of approximately 3km of new rising main in the R403 from Clane to Sallins. (Complete)
- In Clane town, works will take place in the green area adjacent to the Alexandra Manor Estate & River Liffey. These works are due to commence on Monday 16 November 2020. Irish Water expects these works to last for approximately 4 weeks. Works will take place weekdays between 7.00am and 7.00pm.
- Please be aware that in order to carry out the works safely, the footpath from Abbeyland roundabout adjacent to Alexandra Manor Estate will be closed as far as the Liffey Walkway. Access to the Liffey Walkway will be maintained via the footpath on the opposite side of the road. Please see the below map for further information.
We apologise for any inconvenience this necessary work causes.
What is involved?
- Lay over 18km of new gravity sewers and rising mains to reinforce and improve the existing wastewater sewer network.
- Upgrade wastewater pumping stations at Sallins, Clane and Monread (Naas).
- Build additional storm water storage tanks at all three pumping stations
- Wastewater will continue to be pumped to Osberstown for treatment.
Why are these works necessary?
- The existing wastewater network is no longer fit for purpose. The system doesn’t have sufficient capacity to move wastewater to the treatment plant during storms, and some of the pipes are old and ready for replacement.
- There have been storm water overflows at a number of locations, which does not comply with European legislation or Environmental Protection Agency requirements.
- To increase the capacity of the network we are upgrading three pumping stations and upgrading and replacing existing sewers to ensure they are large enough and in good condition. We will include stormwater storage at each of the pumping stations which will improve resilience during storms.
- Improved water quality in the river Liffey and tributaries, in compliance with national and EU legislation.
- Improved energy efficiency at all three pumping stations.
- The sewer network will have increased capacity to support future growth in the area.
