A Boil Water Notice has been imposed on Glenamaddy Public Water Supply in the areas of Glenamaddy, Cloonminda, Bushtown and the Knockmascahill Group Water Scheme.
Irish Water says the Boil Water Notice has been put in place due to issues with the ultra violet disinfection of the water at Glenamaddy Water Treatment Plant.
The notice affects approximately 800 people supplied by Glenamaddy Public Water Supply.
Experts from Irish Water and Galway County Council are working to assess the situation and are investigating the issues at the plant with a view to implementing solutions to lift the notice as quickly and as safely as possible.
In the meantime, all customers on this supply are advised to boil their water before use until further notice. Customers in the area served by Glenamaddy Public Water Supply Scheme will notice increased levels of chlorine in their water supply in the coming days as work is undertaken to resolve the issue.
