Notice lifted following satisfactory water quality results

Following consultation with the Health Service Executive, Irish Water and Dún Laoghaire – Rathdown County Council are pleased to confirm that the Boil Water Notice for the area supplied by the Glencullen Public Water Supply has now been lifted following the results of water quality tests.

Glencullen now supplied from Ballymore Eustace Water Treatment Plant

The Boil Water Notice was put in place as a precautionary measure on 21 December following the detection of giardia in the Glencullen Public Water Supply. Irish Water Drinking Water Compliance, operational experts and Asset Delivery teams worked with colleagues in Dún Laoghaire – Rathdown County Council to resolve this situation as soon as possible. Cleaning works at the Ballyedmonduff Reservoir and Glencullen Reservoir were carried out, as well as disinfection and flushing of sections of the water network. Control upgrades and commissioning of a disinfection booster were also carried out during the works. The Glencullen Public Water Supply has been taken out of operation and DLR Zone 4 (Glencullen) is now supplied with water from Ballymore Eustace Water Treatment Plant.

Irish Water would like to apologise for the inconvenience caused by this incident and thank customers for their patience in complying with this notice. Irish Water and Dun Laoghaire – Rathdown County Council acknowledge the patience, cooperation and assistance of the general public during this period. Our priority is to provide safe clean drinking water and safeguarding that water supply for the future is a vital focus.
