They may result in low pressure, or loss of supply.
Irish Water is conducting works in 2 areas in Kildare today, which will likely result in supply disruption.
Repairs to a burst main, serving Woodview, Clogherinkoe, get underway at 10am this morning.
That's the same start time for mains repair works in Moyglare Abbey, Maynooth.
In both instances, homes and buisnesses in the wider area may experience low pressure or loss of supply.
The works are scheduled to finish at 4pm and 5 O'clock, respectively.
Irish Water says "Supply may take 2-3 hours to fully return to all affected properties."
