Irish Water's warning supplies in the Greater Dublin Region could fail after 70 days.

Current levels are still under threat following the heatwave.

The hosepipe ban remains in place around the country with restrictions in place in some areas.

Irish Water managing director Jerry Grant said further conservation will be needed in the coming weeks.

“About the 10th or 12th of May we had 150 days of storage in Poulaphouca,” he said.

“It is an enormous source of water and it saves the city year in, year out.

“We used 80 days of that storage in 83 days – in other words, almost nothing was contributed to the storage in that period.

“We have about 70 days of usable water left for the Greater Dublin Area – 1.6 million people.

“We could be 90 days before that lake starts to rise, depending on how dry the autumn is.”

Met Éireann recorded 63.9 millimetres of rainfall at Dublin Airport across May, June and July this year – significantly less than in the previous three years.

Last year, the forecaster recorded 172.1 millimetres, with 149 recorded in 2016 and 173.8 recorded in 2015.

Meanwhile leakage from water mains pipes in Ireland is at 49% - making the country the worst performer in western Europe for pipe leakage.
