Raw sewage is being discharged into rivers and bathing areas at more than 40 locations nationwide.

A report published by the Environmental Protection Agency found that 42 areas had no waste water treatment plant, which means effluent is entering waterways putting peoples' health and the environment at risk.

Some of Ireland's main tourist attractions are affected, including top surfing spot Bundoran in Co Donegal, Cobh in Co Cork and Roundstone in Connemara.

The urban waste water report also found that of the 170 treatment plants in the country 44 do not comply with EU quality standards.
