Boil water notice for 17,000 households in Wicklow and Dún Laoghaire

Irish Water has issued a precautionary boil water notice to more than 17,000 households in south Dublin and north Wicklow.

It said in a statement on Monday that high turbidity at a treated water reservoir at Vartry Treatment Plant meant a small amount of water was “inadequately disinfected” for a short period. Turbidity is the measure of how clear the water is, with a higher level indicating a greater number of particles in the water.

The utility said the water was still safe for washing but should be boiled for drinking, preparation of food and brushing teeth.

The Environmental Protection Agency has been notified of the incident.
