New water main project secures supply for Wicklow towns
Uisce Éireann begins constructing a vital new water main to connect Annamoe and Laragh with the secure Vartry zone. This infrastructure upgrade ensures reliable drinking water for residents and supports future regional growth by the end of 2026.
Critical Infrastructure Works Begin in Wicklow
Uisce Éireann has officially commenced a major engineering project designed to fortify the water supply network serving Annamoe, Laragh, and Glendalough in County Wicklow. The initiative, known as the Raheen Water Supply Rationalisation Project, aims to significantly enhance the resilience and reliability of local water services for generations.
The core of this development involves building a new 3.2km water main linking the Roundwood Reservoir to the Raheen Water Treatment Plant. This strategic connection will integrate the Laragh-Annamoe supply with the robust Vartry water zone, ensuring a more secure resource for households and businesses alike.
Barry Butler from Uisce Éireann highlighted the urgency of the work, noting that current infrastructure cannot meet existing demand. He stated, "This project will not only improve water supply for our customers in the area, it will also facilitate future growth and development, including the delivery of new housing." The investment is crucial for maintaining clean, safe drinking water while accommodating the region's expansion.
Construction activities are taking place along sections of roads L-1059, L-1060, and R755. David Walsh Civil Engineering Ltd. has been appointed to execute the works on behalf of the utility provider. While the project is expected to conclude by late 2026, traffic management measures will be implemented to ensure safety.
To facilitate the build, phased road closures are scheduled for August 2026, lasting approximately two months on specific sections. Uisce Éireann has committed to maintaining local and emergency access at all times, utilising temporary Stop/Go systems where necessary to minimise disruption to commuters.
Residents with queries regarding the project can contact Uisce Éireann directly on 1800 278 278 or monitor regular updates on their website. A free text alert service is also available for those wishing to stay informed about potential outages and construction progress.
