A boil water notice has been put in place in Millstreet, Ballydaly, Laght, Drishane and Keale in Co Cork.
Irish Water issued the notice following the detection of low levels of cryptosporidium.
Irish Water has identified this as a vulnerable supply due to the lack of adequate treatment and has been carrying out regular testing of the supply to ensure there was no threat to public health.
In order to address the disinfection issue, funding of €210,000 was provided for the installation of two ultraviolet (UV) disinfection units, micro filters and ancillary works at the Millstreet Water Treatment Plant. Contractors were appointed last month and are currently working on site to install this system. This will ensure that water from this supply has a fully validated cryptosporidium inactivation barrier, which will treat water for cryptosporidium and mitigate the risk. This work is expected to be complete in mid June, after which Irish Water will liaise with the HSE with a view to having the Boil Water Notice removed as soon as possible.
Irish Water apologised for any inconvenience.
