Garda investigation into oil spill at Lorrha water treatment plant, Tipperary

An estimated 30,000 litres of oil-contaminated wastewater were discharged at the Lorrha Wastewater Treatment Plant in North Tipperary over the weekend of 11 to 12 April 2026, posing a significant threat to the River Shannon and Lough Derg, both EU-designated Special Areas of Conservation. Uisce Éireann said the oil was intercepted early and contained within the system, and the wastewater was removed for specialist treatment. A multi-agency investigation involving gardaí, the EPA and Inland Fisheries Ireland was opened to identify the origin of the discharge. As of 13 May 2026, the investigation was continuing, with no suspect named and no arrest or charge reported.
