Drinking Water Quality (Public Supplies)

In 2021, the quality of public water supplies remained very good with >99% of samples complying with microbiological and chemical standards. During 2021, 70 boil notices were issued affecting 211,000 people. This is in comparison to the 43 boil notices issued in 2020 affecting 75,000 people. . Over 40% (29 of 70) of boil water notices in 2021 were 'long-term', i.e. they were in place for longer than 30 days. There were 52 supplies (supplying water to 375,000 consumers) on the Remedial Action List at the end of 2020, a reduction from 46 supplies (and >1 million customers) at the end of 2020. Irish Water need to continue to progress remedial works on the outstanding 'at risk' supplies so that the threat of long-term boil water notices and other chemical failures is eliminated. Based on monitoring results, the quality of the water in our public supplies is very good. However, the vulnerabilities in the second largest water treatment plant in the country highlight a lack of resilience in our water supplies. It is of paramount importance that Irish Water take action to ensure the resilience of supplies.
