A boil water notice for over 10,000 Irish Water customers living in the east Cork area has been lifted with immediate effect.

The notice was put in place after cloudiness in the water was detected on 27 February 2016.

The scheme draws its water from the Dower Spring Source and concerns were identified in relation to the effective operation of the UV disinfection at Kilvagh Water Treatment Plant, which could not be guaranteed during periods of high turbidity.

Irish Water has now installed additional treatment, storage and controls at Kilvagh Treatment Plant to address the extreme raw water qualities which were experienced during adverse weather conditions in winter 2015/2016. This €1million investment in a new filtration system and other upgrade works will provide effective year round protection in the event of future high turbidity and a robust cryptosporidium barrier. Two microfiltration units have been installed prior to the new UV disinfection unit. New plant shutdown controls have been put in place to prevent inadequately treated water entering the water supply network.
