Uisce Éireann completes crucial new €29m trunk watermain to Swords

A €29 million investment by Uisce Éireann to build a new trunk watermain from Ballycoolin Reservoir to Swords has been completed.

The regional trunk watermain will safeguard the supply for over 350,000 customers by providing an additional pipeline that can transfer up to 90 million litres of water a day to North Dublin.

Crucial for the security of water supply to North Dublin and parts of Dublin City, the watermain will support existing and future residential developments as well as large institutional and commercial entities including local hospitals and Dublin Airport.

A major factor in the project’s success was collaboration with private landowners, as over 90% of the 7.5km pipeline crossed through private agricultural lands.

Uisce Éireann wishes to thank these landowners for their vital cooperation and support in facilitating the construction of this infrastructure.

Speaking about the project, William McKnight Infrastructure Delivery Lead of Uisce Éireann said, “A safe secure water supply is essential for businesses and communities in the Greater Dublin Area (GDA).

“The delivery of this significant project will support existing and future residential and commercial developments and is one of a number of water projects being delivered in the GDA.

“We are very grateful to all of the landowners who have played a major role in supporting this project, and their wider community.”

“We aim to build infrastructure that protects and where possible enhances the ecosystem.

“To deliver this commitment after the pipeline was constructed, we planted c.23,000 native trees and shrubs along its route.”

David Branagan, Communications and Engagement Manager, Fingal Chamber said, “Uisce Éireann’s new water infrastructure is a critical development for the continued economic growth of North Dublin.

“Reliable access to a secure water supply is not only essential for the well-being of our communities but also plays a critical role in supporting local businesses, healthcare facilities, and key institutions.

“Fingal Chamber welcomes this significant investment and commitment to building future-proofed infrastructure.

“We commend Uisce Éireann for overcoming complexities and challenges and delivering this substantial and much needed project. This €29 million will ensure Fingal remains a vibrant and attractive location for investment.”

Tselopile Tlou, Uisce Éireann’s Operations Lead, said, “This important water project will benefit many communities across North Dublin and parts of Dublin City.

“The existing infrastructure, which was constructed in the 1960’s, had inadequate capacity to meet existing peak demands.

“This resulted in occasional low pressure and we were also unable to provide for future growth in demand.”

The project was delivered by Roadbridge Ltd and GMC Utilities Group Ltd. who worked closely and collaboratively with our employer representative Nicholas O’Dwyer Ltd. and site supervision team from Atkins Ltd.
