Water curbs hit Irish bars and hotels at busiest time
Pubs, hotels and nightclubs in the Republic face having no water at night at the height of the tourist season.
Widespread restrictions to be introduced from Monday evening across Dublin city centre and suburbs and parts of Wicklow could lead to loss of supply for businesses without a back-up in place, Irish Water said.
More than 30 locations in an area stretching from Bray in Wicklow to Finglas on Dublin's northside and Lucan to the west will be affected.
Other areas across the country have already been hit with night-time restrictions, including Athlone in Co Westmeath and parts of Galway city.
"What we're trying to do is maximise the amount of water we can save while minimising the impact on homes and business. It's very hard to do," Irish Water corporate affairs manager Kate Gannon said.
"For general customers, some on high ground and remote ends of the network will experience low pressure."
