The Environmental Protection Agency has warned that it could take two decades to bring the country’s wastewater infrastructure up to standard.
A new report by the EPA shows that 8 towns and villages across Donegal have no treatment plants and continue to release untreated sewage into the environment.
The earliest estimated date for treatment in the areas identified is 2023 while Moville will continue to discharge untreated sewage until 2027.
The watchdog also says Moville failed to comply with EU treatment standards in 2020.
Five areas in the county have also been identified as being prioritised to protect surface waters.
The EPA says Irish Water must complete overdue assessments of the impact of waste water discharges at designated shellfish waters in Donegal at Lough Swilly, McSwyres Bay and Sheephaven.
