By finding and repairing a major leak in Letterkenny, Uisce Éireann has saved 150,000 litres of water daily.
This significant leak at Main Street, Letterkenny was repaired under the Leakage Reduction Programme with enough water saved to supply 1,300 people a day.
Uisce Éireann, working with their regional contractor Farrans and Larsen Water Management, carried out an extensive review of the network under the Find & Fix scheme.
Find & Fix involves leak detection crews undertaking surveys using multiple technologies, including sounding equipment, to locate leaks on our water network. Advanced acoustic logging technology was also deployed in Letterkenny which led to this leak being pinpointed within a short time period.
Patricia Lowry, Leakage Reduction Programme Manager with Uisce Éireann, described the find as “one of the most significant savings of our precious resource this year in the North-West region.”
“It’s hard to understand that more than 150,000 litres of clean drinking water were disappearing underground every day in the centre of Letterkenny. Water is a valuable resource, so finding this leak and successfully repairing it was of paramount importance. For our leak detection team to have found this leak and the subsequent improvement to the network is a massive win.”
This project in County Donegal is one example of how Uisce Éireann is working to reduce leaks every day. Fixing leaks can be complicated. We have more than 63,000km of water pipes underground in Ireland – enough to circle the earth one and a half times. Most leaks aren’t visible, resulting in precious water being lost, but we are making progress.
