Irish Water has introduced nighttime restrictions on water supply in parts of Galway due to rising demand in the hot weather and in order to maintain daytime supply.
Irish Water said that as the dry weather continues, so too does the high level of domestic, commercial and agricultural demand.
It appealed to people across the country to be mindful of how they use water.
In Co Galway, restrictions are in place from 11pm to 7am over the weekend in the Carna/Kilkieran and Roundstone areas.
Irish Water said the vast majority of its 750 water treatment plants continue to meet the demand for water supply but is still asking the public to continue to conserve water over the coming weeks.
It said that even small changes can make a significant difference, for example turning off the hose and avoiding power washing, can all help ensure there is enough water for everyone as we go through the rest of the summer and into autumn.
