Galway City Council hopes to have a full water supply restored in the next 24 hours following a major leak in the supply network last night.
The leak has now been contained, and the council say it is now waiting for the reservoir to fill up so full water supply can be restored tonight or, at the latest, tomorrow morning.
The leak occurred along a two-kilometre section in the rising mains between Terryland treatment plant and the Clifton Hill reservoir. The cuts in water supply extended across the west side of the city as far as Barna and Moycullen in the county.
Three water tankers are in place around the city at Ballymoneen Road, the B&Q shopping centre and Bushy Park. Residents were being asked to boil all water taken from tankers, while the local authority said that there was no issue with the general quality of water.
Last year, over 2,000 people became ill and some 90,000 residents had to boil their water for five months when the supply was contaminated with the cryptosporidium parasite.
