Irish Water warns it will take 'years' to bring public water supply to highest standards

Irish Water said it invested more than €460m in Ireland’s water treatment plants and networks in 2021, with 12 water treatment plants built or upgraded and an additional 39 sites upgraded.

Irish Water has warned it will take "a number of years and high levels of investment" to bring the public supply to the highest standards, following criticism from the environmental watchdog.

The Environmental Protection Agency (EPA) said while more than 99% of Ireland’s drinking water supplies were up to scratch, there were a number of serious incidents in 2021.
