Uisce Éireann and South Dublin County Council (SDCC) are collaborating on a dual-infrastructure project involving water main replacement and surface water pipeline installation along the R405 Hazelhatch Road.

The partnership aims to eliminate leaks, reduce pipe bursts, and prevent flooding, while ensuring a resilient water supply for residents and businesses.

The works are also designed to provide the necessary network capacity to support ongoing and future developments in Celbridge and Newcastle, including the facilitation of new housing projects.

The Uisce Éireann portion of the project, which began in October 2025, involves replacing 5.25km of water main between Celbridge, Co Kildare, and Newcastle, Co Dublin. To date, 850 metres of the new main has been successfully installed. Simultaneously, SDCC is overseeing the installation of 2.5km of surface water pipeline from Newcastle to Hazelhatch, along with four communications ducts.

Nicola Butler of Uisce Éireann highlighted the benefits of the joint delivery approach: "We are excited by the multiple benefits that the co-delivery of these works will bring. By working in partnership with SDCC, we are able to reduce disruption for the community and install three utilities at once. The synergy between two public bodies that is on display here is a particularly pleasing aspect of this phase of the project."

To facilitate the safe delivery of the infrastructure by GMC Utilities Group Ltd., a significant road closure will be required. The R405 Hazelhatch Road will be closed between its junctions with Loughtown Road and Athgoe Road from Monday, 23 February until the end of August 2026. A signposted diversion will be operational throughout this period, and access for local residents and emergency services will be maintained at all times.

This initiative is part of Uisce Éireann's National Leakage Reduction Programme. Nationally, the programme has helped reduce water leakage from 49% in 2014 to a record low of 36%. With over 65,000 km of underground pipes across Ireland, the programme remains a critical component of Uisce Éireann's commitment to providing safe drinking water and supporting sustainable community growth.
