Major water network upgrade in Letterkenny nears completion
800 metres of new water mains installed as key project to support future housing growth enters final phase
Letterkenny is set to benefit from increased water network capacity and resilience as a major water infrastructure project on Leck Road nears completion. More than 800 metres of new water mains have now been installed, with the project entering its final phase.
Uisce Éireann’s investment in the town will help ensure the network can support future housing development and planned growth in the area.
The works have involved the installation of more than 800 metres of new water mains along the L1114 Leck Road, between the N13 Ballybofey Road and the L1094 Cullion Road.
As the project enters its final stage, the remaining 20 metres of water main will be installed across the bridge on Leck Road. To allow these works to be completed safely, a temporary road closure will be in place for three weeks, Monday to Friday, between 10am and 7pm. Clearly signposted diversion routes will be provided for road users.
Speaking about the project, Uisce Éireann Programme Manager, Patricia Lowry, said: “We are delighted to be nearing completion of this important project, which will increase capacity within the local water network and help support future housing growth in Letterkenny. Most of the works have now been completed and the benefits of this investment will help ensure the network can support future homes and development in the area.
“A temporary road closure is required from next week to safely complete the final section of works across the bridge. We would like to thank local residents, businesses and road users for their continued patience and cooperation while we complete this final stage of the project.”
Works are being carried out on behalf of Uisce Éireann by Farrans and are expected to be completed in November.
The project forms part of Uisce Éireann's Accelerated Growth Programme, which is delivering key water and wastewater infrastructure projects in areas where growth and development are planned.

Uisce Éireann is set to commence major water mains upgrade works in Letterkenny to increase capacity in the local network, deliver a stronger and more reliable water supply and support housing development in the area.
The project will involve the installation of more than 800 metres of new water mains on Leck Road, along the L1114 between the N13 Ballybofey Road and the L1094 Cullion Road. The project is being delivered as part of Uisce Éireann’s Accelerated Growth Programme and will provide capacity for future housing growth in the area.
These works will increase capacity within the local water network, helping to support future housing delivery and planned growth in Letterkenny. The investment forms part of Uisce Éireann’s ongoing programme to deliver essential water infrastructure in areas where it is needed most.
Works will be carried out on behalf of Uisce Éireann by Farrans and are expected to be completed by late autumn 2026.
Speaking about the project, Uisce Éireann Programme Manager, Patricia Lowry, said: “This project is an important step in supporting the continued growth of Letterkenny and ensuring the local network can meet future demand. The installation of new water mains on Leck Road will increase capacity and help provide the infrastructure needed to support new homes and sustainable development.
“Our teams are also on the ground in Letterkenny upgrading the network in the Woodlands area of the town, where we are replacing approximately 1.5km of water mains to further boost capacity and secure supply. We understand that works of this nature can be disruptive, and we would like to thank the local community in advance for their patience and cooperation while we deliver these essential works.”
To safely facilitate the works on Leck Road, traffic management will be in place, including a road closure along the section of works. Local and emergency access will be maintained at all times.
Works will take place from Monday to Friday between 10am and 7pm to minimise disruption, and the road will be open outside of these times. Work areas will be limited to short sections where possible.
