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. (In progress)

Diversion routes will be clearly signposted, as agreed with Kildare County Council and An Garda Síochána. Emergency Access and restricted Local Access will be maintained, including access to local businesses. 

A temporary stop/go traffic light system will be in place over the coming weeks on the R407, between Clane and Sallins, to facilitate installation of key pipework as part of the project. These works are commencing on Wednesday 8 July and are expected to last for approximately 14 weeks. The length of pipeline to be installed is approximately 3 kilometres. This will be completed in 300 metre stop/go phases.

Please be advised that journey times may take longer than usual during these works.

Please see the map below for further information.

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.
