Demand for water remains 'critically high' in the Dublin area, Irish Water has warned.
It comes amid the continuing heatwave - with temperatures of 25-26 degrees forecast for Dublin today, and as high as 30 degrees elsewhere in Ireland.
Some households in north Dublin have already experienced water outages, alongside others in parts of Athlone, Kilkenny and Longford.
In the past 24 hours, demand hit 603 megalitres - a small decrease on demand compared to the previous day, but still less than 10 megalitres below daily production capacity.
Irish Water has reiterated its call for people to conserve water however possible - such as taking short showers instead of baths, and by avoiding using hoses to water gardens.
Irish Water's Kate Gannon warned: "If the drought is prolonged, water restrictions would become unavoidable if demand does not continue to drop.
"Irish Water are appealing to the public to be continue to be mindful of their water usage. Every effort someone makes in their home or business impacts their neighbour and community."
She highlighted the actions of Dublin Bus as an example of effective water conservation, after the transport company pledged to cut down on washing its fleet while water demand remains high.
