Uisce Éireann fined over Cavan River pollution

Inland Fisheries Ireland has welcomed the outcome of a case brought against Uisce Éireann involving sewage pollution of the Cavan Town river.

It comes after Inland Fisheries Ireland (IFI) previously secured a conviction last October against the utility provider for polluting the Ballinagh River, an incident that caused the death of 160 fish.

The incident at the Cavan Town river saw test samples taken downstream from Uisce Éireann’s wastewater treatment plant, which showed high levels of pollutants. Large amounts of sewage fungus – bacteria, fungus and algae that reduce oxygen levels - were also visible on the bed of the river.

A fine of €2,000, plus costs and expenses of €3,197, were imposed at a hearing on the matter at Cavan District Court on December 1.

Welcoming the verdict, Dr Milton Matthews, director of IFI’s North-Western River Basin District said: “The presence of sewage fungus in the river is indicative of chronic organic pollution of Cavan Town river at this location... with significant impact on fish, invertebrates and all aquatic life in the river.

“There were significant breaches of the licence emission limits for Biochemical Oxygen Demand (BOD) - oxygen required to break down organic matter in the water - and high ammonia levels.

Dr Matthews added: “Sample results taken at the location indicated that ammonia levels were over 115 times higher than permitted discharge limits, and eight times higher than permissible for BOD limits as stipulated for this treatment plant.”

The pollution event took place on February 3, 2023.

The court heard that, due to ongoing issues at the plant, Senior IFI Fisheries Environmental Officer Ailish Keane had taken samples for analysis, which indicated high levels of pollutants.

The conviction was secured under Section 171 of the Fisheries (Consolidation) Act 1959 – legislation regarding protection of fishing waters from harmful pollutants.
