15 areas around the country are at risk of drought as water supplies come under pressure due to the hot weather.
The Irish Daily Mail reports that areas in Cork, Clare Wexford, and Galway are being monitored by Irish Water as temperatures reach record breaking levels this week.
Irish Water say four areas in Cork are at risk of drought: Clonakilty, Roberts Cove, Whitechurch and Coppeen.
Night time restrictions could be introduced to restore the water levels in reservoirs.
Irish Water say they will be able to cope with the extra demand over the summer months but are asking the public to conserve water where they can.
