Irish Water is investing €5.5 million to replace 31kms of ageing water mains across Longford benefiting communities in Aughnacliffe, Ballagh, Cahanagh, Cloonmee, Drumlish, Drumure, Edgeworthstown, Granard and Newtownforbes.
The new water mains will provide a more reliable water supply with fewer interruptions.
It will also improve water pressure as leakage on these sections of the water mains will be reduced.
The contract for the project was recently signed and it is estimated that work will start in April 2017 and take approximately 18 months to complete.
The project will be carried out in stages and will be limited to short sections at a time to minimise disruption to residents, businesses and road users.
The works will involve some short-term water shut offs for a number of hours over a day or two in each area when the pipes are being connected to the new water mains.
Householders and businesses will be given a minimum of 48 hours prior notice of any planned water shut offs.
