Parts of the Williamstown Water Supply Scheme will experience disruptions tomorrow, as the scheme connects to Lough Mask.
All areas of the scheme supplied by Kilnaleg reservoir will see their water supply temporarily switched off as the connection is made to Lough Mask Regional Supply.
Galway county council advises that the interruption will last from 9am to 5pm on Thursday, August 30.
Other parts of the scheme, including the town, will not be affected.
The Williamstown water supply scheme was recently taken off the EPA’s blacklist with the completion of the extension to Lough Mask.
The €10 million upgrade to the Williamstown supply scheme involved laying 23km of pipes, as well as building a new pumping station at Ballyhaunis in Mayo, and a reservoir at Garranlahan.
Williamstown had been on the EPA blacklist since 2016 because it was at risk of developing Trihalomethanes, a carcinogenic chemical that forms when chlorine mixes with dissolved organic matter in water.
