Two separate boil water notices are to remain in place in Tipperary until further notice.
Uisce Éireann says a notice issued on September 3rd will remain in place for around 4000 customers on the Carrick On Suir (Linguan) Public Water Supply.
This is due to treatment issues at the water treatment plant.
Meanwhile, a boil water notice issued to customers on the Horse and Jockey Public Water Supply, which was also issued on September 3rd, will also remain in place until further notice.
Around 600 customers are affected with Uisce Éireann citing increased turbidity in the raw water source as the reason for the disruption.
The national body says they are are working to lift both notices as quickly and as safely as possible.
