Duleek to Navan Trunk Watermain

Uisce Éireann has received Planning and CPO approvals to develop a new trunk watermain in Co. Meath between Duleek and Navan. This project will add resilience to Navan’s water supply.

Uisce Éireann, working in partnership with Meath County Council, has confirmed the necessary CPO and received planning consents for the installation of proposed new infrastructure between Duleek and Navan. When complete this new infrastructure will enable Uisce Éireann maintain drinking water supply to Navan if there is any planned or unplanned disruption at Navan’s Water Treatment Plant at Liscarton.  This will be achieved by diverting available treated water from Uisce Éireann’s South Louth/East Meath Water Resource Zone at Duleek and pumping it to Navan’s treated water storage reservoirs at Carn Hill and Proudstown.

The provision of this new 16 km trunk watermain and pumping station is in line with Uisce Éireann's strategic plans to improve resilience in the network and reduce the number of isolated water resource zones where large populations are vulnerable to interruption to supply.

What are the benefits of these works?

When complete this new infrastructure will enable Uisce Éireann to maintain drinking water supply to Navan, if there is any planned or unplanned disruption at Navan’s Water Treatment Plant at Liscarton. This will be achieved by diverting available treated water from Uisce Éireann’s South Louth/East Meath Water Resource Zone from Duleek and pumping it to Navan’s treated water storage reservoirs at Carn Hill and Proudstown.

What is involved as part of this project?

These works will involve the construction 16 km of new trunk watermains in existing public roads between Duleek and Navan:

  • L1610 Boolies Little (South of Duleek) to the junction with the N2 at Balrath
  • R153 Balrath to Kentstown
  • R153 Kentstown to Casey’s Cross, Navan

The proposed works will require crossing under the River Boyne between lands adjacent to St Mary’s Cemetery on the Boyne Road and lands adjacent to Blackcastle Estate on the Slane Road. An underground crossing will also be required under the Navan to Drogheda railway line. However, to minimise the impact to the community and the environment, it is planned to deliver both crossings using trenchless pipeline installation techniques.

The construction of the new infrastructure will take approximately two years.

What is happening next?

The procurement process for the associated Works Contract is close to completion and the achievement of these key milestones will allow the project to commence works on site in 2023.

As the new trunk watermain is in the public road, the project will require a significant amount of Traffic Management. This will be implemented in consultation with Meath County Council. Local access and emergency access will always be maintained and regular engagement with the community is planned throughout the project duration. We will endeavour to keep you updated as the project progresses.

Where will the construction be carried out?

Will there be traffic management in place?

As the new trunk watermain is in the public road the project will require a significant amount of Traffic Management. Typical traffic management measures may include temporary traffic lights, stop/go systems, road closures and diversions. Signs will be erected in advance of works commencing to ensure road users are aware of current and upcoming traffic measures.

Local access and emergency access will always be maintained and regular engagement with the community is planned throughout the project duration.

We will provide further information on traffic management measures as the project progresses.
