The scheme was designed to reduce the risk of flooding to three large commercial properties and reducing the risk of damage to the infrastructure of the main Belfast to Dublin railway line. The area had a history of flooding from the existing watercourse.
The flood alleviation scheme involved the installation of 290m of in-situ reinforced floodwall, as well as the construction of 180m of precast box and pipe culvert. This helped divert the existing watercourse and dramatically increase the flow capacity of the existing network.
Key challenges included constructing the works through several land ownerships, requiring extensive landowner liaison and careful planning in advance of works such as craneage and deep excavation.
