Enniscorthy Flood Defence Scheme

OPW Wexford Logos


The town of Enniscorthy, located on the banks of the River Slaney, has a long history of flooding. Extreme floods have occurred in 1924, 1947, 1965, 2000 and more recently in 2015. Flooding represents a risk to health and safety, and has resulted in significant property damage and traffic disruption in the town. Flooding has adversely affected commercial activity in the town and its environs.

The Enniscorthy Flood Defence Scheme, formally referred to as the River Slaney (Enniscorthy) Drainage Scheme, proposes a number of measures to prevent flooding in the town. These include river channel widening, river deepening, bridge relocation, and the construction of extensive glass panelled flood walls through the town.

The proposed scheme covers a 3.5km stretch of the River Slaney, extending from 1.5km upstream of Enniscorthy Bridge to 2km downstream. The main elements of the scheme include:

  • Construction of flood defence walls on both banks, upstream of Enniscorthy Bridge, through the town, finishing just south of the Promenade.
  • River channel widening and deepening
  • In partnership with Irish Rail improving the hydraulic capacity at the railway bridge.
  • Deepening of the riverbed beneath the Old Enniscorthy Bridge.
  • Construction of a new road bridge over the River Slaney and railway line, located to the south of Enniscorthy.
  • Removal of the existing Seamus Rafter Bridge.
  • Construction of a new pedestrian bridge in the town centre.

Scheme costs are estimated at between €40M and €45M.
