Areas impacted will include Coill Dubh, Prosperous, Derrinturn, Kilmeage, Robertstown, Allenwood, and surrounding areas.
Uisce Éireann is advising customers supplied by the Allenwood Reservoir that low levels at the reservoir will impact water supplies to customers overnight.
From 9pm tonight, waterflow at the plant will be reduced to allow for levels to replenish.
Areas impacted will include Coill Dubh, Prosperous, Derrinturn, Kilmeage, Robertstown, Allenwood, and surrounding areas.
According to Uisce Éireann, "extremely high demand on the network has led to water levels in the Allenwood Reservoir falling to critically low levels over the last seven days."
Normal supply is expected to resume from approximately 7am tomorrow morning.
It may take up to 24 hours for normal supply to return to customers in some areas.
