An environmental group is to bring legal proceedings against Roscommon Council over flood works currently underway in the south of the county.
The Friends of the Irish Environment will apply to The High Court seeking a Judicial Review over the Lough Funshinagh pumping plan currently being installed on the problem lake.
Several homes and farms surrounding the turlough are currently threatened by the rising water, the new works set to be completed early in the new year.
Friends of the Irish Environment were behind a high court action during the summer that saw the local authority forced to halt all work on the flood relief scheme.
Following the court decision, Roscommon County Council enacted a smaller scale solution to tackle rising water levels.
Under the plan, 2 pumps will transport floodwater from Lough Funshinagh to an existing stream that flows into Lough Ree at Carnagh Bay.
FIE recently lost a contempt of court hearing challenging the new plan, and have now confirmed to Shannonside Northern Sound, that they plan to launch a judicial review on the decision.
In their statement, Friends of the Irish Environment state they have considerable sympathy for the locals and understand further uncertainty will increase the burden on the residents
However, they say the methods of the local authority represents an attempted bypass of environmental and planning regulations, which could encourage other state bodies to do the same.
The group continues by saying the flood relief plan does not consider the risk of those living below the exit pipe near Lough Ree, and the risks they say they face from future flooding.
