Irish Water are advising customers in Carrigrohane, Victoria Cross and Farranlea Road that their supply might be impacted between 8pm and midnight tomorrow and Wednesday.
One lane will be closed to traffic while works are being carried out.
Following these improvement works water supply may take 2-3 hours to return as water refills the network.
Irish Water say they understand this type of work can be inconvenient and will ensure their work crews make every effort to minimise any disruption.
