Senior Fisheries Environmental Officer with Inland Fisheries Ireland (IFI), Michaela Kirrane, told Judge Coughlan that during a routine inspection of the river on the 25/05/2017 it was noted that the river appeared to be in a poor condition downstream of the discharge point from Ardee Wastewater Treatment Plant. A series of water samples were taken and analysis confirmed that the discharge from the wastewater treatment plant was having a deleterious impact on the quality of the River Dee.

Irish Water co-operated fully with Inland Fisheries Ireland’s investigation and remediation works were carried out. Upgrade works are currently underway to increase capacity at the wastewater treatment plant. 

Irish Water was fined €4,500 with costs and expenses awarded to IFI amounting to €4,381.61.
