The 124 homes in Galmoy affected by water issues in recent weeks will have to wait until at least the end of August before normal service is resumed.
Following advice from the HSE, Irish Water and Kilkenny County Council, as a precautionary measure and pending further investigation, issued a 'boil water notice' on both the public water supply and group water scheme on July 8. This followed sampling and testing of the reservoir at the water treatment plant, which indicated that the disinfection of treated water may have been compromised.
The accumulation of silt in the reservoir over time has been identified as the cause and arrangements are being made to clean the reservoir. The boil water notice is to remain in place until this work is completed.
Irish Water has now engaged a contractor to complete the inspection, clean and sterilise the reservoir and to construct a reservoir bypass to allow supply be maintained to customers during the cleaning works. The construction of this bypass will also facilitate routine cleaning of the reservoir without requiring disruption to supply in future.
Works are expected to begin at Galmoy later this week and it is hoped that these works will be complete by the end of August. There will be limited interruptions in supply, potentially of up to four hours during off-peak times, to allow the bypass pipework to be completed. All residents will be notified in advance of any planned shut-offs as part of these works. Following completion, Irish Water and Kilkenny County Council, will undertake a number of tests of water quality at the reservoir. These will then be submitted to the HSE, who will decide when to lift the boil water notice.
Irish Water has said it will continue to keep local residents and councillors updated on these works and our efforts to enable the lifting of the boil water notice as soon as possible.
