Controlling flood risk on Devon’s New Link Road ..


Controlling surface water flooding was a vital consideration in planning and building Mid Devon’s new £8.42 million A3072 Crediton Link Road. By using Hydro-Brake Optimum vortex flow controls as part of a SuDS approach, South West Highways (SWH) & Devon County Council (DCC) were able to meet Environment Agency requirements for discharge limits at a 1 in 100 year level and reduce flood risk in nearby rivers Creedy and Yeo. Three Hydro-Brake Optimum vortex flow controls were fitted with maximum discharges of 5 l/s, 20 l/s and 30 l/s via storage tanks, a swale and an attenuation pond to the field drains and eventually the rivers Creedy and Yeo.
