Ireland’s drinking water remains high, but supplies must become more resilient, says EPA

The quality of drinking water from public supplies remains very high, with over 99.8 per cent of samples compliant with standards. There are 45 supplies serving 497,000 people on the EPA’s list of ‘at-risk’ supplies (Remedial Action List) that need to be addressed by Uisce Eireann. This is down from 57 supplies (serving 561,000 people) in 2023. The were 33 long-term boil water notices in 2024, down one-third from 2023. Progress to protect public health by removing lead from our supply networks and houses is still far too slow.

Ireland’s EPA finds 56% of domestic waste water treatment systems failed inspections in 2024

Ireland’s drinking water quality high, but sustained investment is required for resilient supplies

The quality of drinking water from public supplies remains very high, with over 99.7 per cent of samples compliant with bacterial and chemical limits. The number of people served by “at risk” public water supplies has increased again in 2023 to 561,000, up from 481,000. This is primarily due to detections of persistent THM’s and cryptosporidium. The number of long-term boil water notices was 46 in 2023, almost double the number in 2022. One in twenty supplies failed to meet the THM standard in 2023. Progress to remove lead from our supply networks to protect public health is far too slow.

Uisce Éireann (Irish Water) must use its new investment plan to end wastewater pollution

Over half of Ireland’s waste water discharges are not meeting EU standards set to protect the environment. Uisce Éireann has committed to eliminating raw sewage discharges by 2025 from the majority of the 26 towns and villages with no treatment. Uisce Éireann still does not have clear plans to prevent pollution at some of the most significantly impacted water bodies, and it is vital these are resolved through its new investment plan. Treatment plants must be operated and maintained properly to prevent impacts on the environment.

Ireland’s EPA urges action to improve private drinking water quality

Private drinking water quality is not as good as public water quality The total number of small private supplies remains unknown as not all have registered with their local authority. Eighty four percent of registered small private supplies were monitored in 2022, compared with seventy five percent in 2021. The government review of the rural water sector identified several key issues in the provision of rural water that need to be addressed to protect public health.

Drinking water quality is high in Ireland, but resilience of supplies needs improvement, says EPA

The EPA Drinking Water Quality in Public Supplies Report 2022, shows that over 99.7% of public water supplies comply with bacterial and chemical limits, which means our public water is safe to drink. However, many supplies still lack robust treatment measures to guarantee their long-term resilience and safety. The EPA's Remedial Action List (RAL) identifies "at-risk" […]
