Roscommon County Council says it will continue to actively support the local community around Lough Funshinagh, and will do all it can to ensure the urgent works at the site are allowed to continue as soon as possible.
The council statement comes in the wake of the securing of a High Court injunction by Friends of the Irish Environment.
Roscommon council has said it's with huge regret that it's confirming it's been forced to suspend the urgent flood relief works.
The council says it's engaged an expert legal team and assures the community that it will work in their very best interests to vigorously defend the project.
The council says the water levels on Lough Funshinagh are presently 2.5 metres higher than usual and studies predict a risk of even more flooding in 2022 and beyond.
The statement says the councils' objective in carrying out the remedial works and installing the pipeline was for the protection of people and property, as well as the status of the Special Area of Conservation and the unique features of Lough Funshinagh.
It says the local authority exercised its powers to begin the urgent flood relief works under the Local Government Works Act of 1949 but that is now being challenged by Friends of the Irish Environment on environmental grounds.
