KFM has contacted Uisce Eireann.
Up to 80 residents at Maynooth Lodge Nursing home are without water since Saturday.
That's despite Uisce Eireann carrying out repair works in Maynooth, Clane, Straffan and surrounding areas over the weekend.
A staff member said the situation is very stressful and they have been forced to buy water for residents.
KFM has contacted Uisce Eireann for comment.
