Date: 04-02-2022

Following consultation with the Health Service Executive (HSE), Irish Water and Mayo County Council can confirm that the Boil Water Notice impacting customers supplied by the Kiltimagh Water Supply has been lifted with immediate effect and the water is safe to drink. 

All customers, including group water schemes, served by Kiltimagh Water Supply can now resume normal use of the water supply for drinking, food preparation and brushing teeth. 

The Boil Water Notice was issued as a precautionary measure on Wednesday, 2 February to protect the health of a population of approximately 1,800 customers following issues with the disinfection process at Kiltimagh Water Treatment Plant. 

Irish Water’s drinking water compliance and operational experts worked to resolve the situation as quickly and as safely as possible and following a number of satisfactory water samples and an audit of the plant, the Boil Water notice was lifted.

Ger Greally, Irish Water’s Asset Operations Lead, acknowledged the impact of the notice on the community and thanked customers for their patience.
