93% of Ireland's large towns and cities met EU sewage standards in 2025
The Environmental Protection Agency's latest report shows 177 of 190 large urban areas in Ireland (93%) met EU wastewater treatment standards in 2025. Uisce Éireann (Irish Water) spent €454m on wastewater services that year, more than €120m above the 2020 figure, and has built new infrastructure, or started building it, in 41 towns and villages that were discharging raw sewage. Work in 2025 included the €550m Ringsend upgrade in Dublin and the completion of the €114m Athlone Main Drainage Scheme.
Our readThe 13 large urban areas short of EU standards in 2025, and the EPA's concerns about incidents at treatment plants, point to years more upgrade work for Irish water contractors.
