People in the greater Dublin area are being asked to conserve water due to a spike in water consumption after the recent hot weather.
Speaking on RTÉ's Morning Ireland, Dublin City Council's Brian Hennelly said that while no shortage is currently being experienced in the region, greater consumption than usual will put a strain on supply.
He said current usage in the Dublin region has increased by an extra 30 million litres on average per day since the warm weather began.
Mr Hennelly said that although there was a lot of rainfall in May and the raw water reservoirs that feed treatment plants are full, there is only a limited capacity to produce drinking water.
"The issue at the moment is that our plants are running at near capacity to match the current usage," he said.
