Athlone Flooding

Case Study:

Flood Defence Scheme - Athlone

Athlone Flooding


Extensive flooding has occurred in Athlone over many years, the most significant being in 1954, 2009 and 2015, all of which were record floods (Figure 1). The Athlone Flood Alleviation Scheme has been progressed to address this issue, with an appropriate allowance for climate change impacts.

Flood barriers to the required height with flood gates, pumping infrastructure, and scheme management plans were implemented as solutions to flooding in the town.

Benefits of solution

This solution has an excellent cost–benefit ratio due to the urban environment and impact of flooding on residential and commercial property, as well as the functioning of the town as a regional centre (Figure 2). The overall costs are likely to be in the region of €12m. As well as the flood protection improvements, significant public realm enhancement works will be undertaken in high-amenity areas adjacent to the River Shannon.
