Vartry Water Supply Scheme

Uisce Éireann carrying out a major upgrade of the Vartry Water Treatment Plant (WTP) and we are committed to consulting with and keeping the local community informed with respect to these works. Once completed the upgrade will secure the long-term future of the water supply for 200,000 people in Wicklow and south Dublin and ensure it meets all drinking water standards.

As part of the upgrade works, Veolia Water Ireland, on behalf of Uisce Éireann, will be installing a siphon main between the Vartry Reservoir and the Vartry WTP. Installation of this pipeline will require closure of the R764 at the location of the bridge between the reservoir and the WTP.

Wicklow County Council has granted a road closure of the R764 for a period of four weeks to allow installation of this main. The road surface will be fully reinstated on completion of installation works.
