Moneymore Flood Alleviation Scheme


Moneymore Flood Alleviation Scheme

Dawson WAM

The area around the Ballymully River in Moneymore, Co. Londonderry has historically been affected by flooding. RPS was appointed by contractor Dawson WAM as detailed designers for a £1.9m flood alleviation scheme funded by DARD Rivers Agency. Access for construction was restricted by the close proximity of residential dwellings, making it a requirement to keep vibrations to an absolute minimum and river had significant fish habitat. RPS proposed an innovative design incorporating

800m of secant pile/ reinforced concrete flood wall

150m of reinforced concrete conventional retaining wall

drainage works

Watercourse management and improvement measures.

The project achieved the highest CEEQUAL score in the UK for a flood alleviation scheme at the time.
