Cottingham & Orchard Park Flood Alleviation Scheme (COPFAS) Phase 2

The Cottingham and Orchard Park Flood Alleviation Scheme Phase 2 was a challenging project, with large volumes of materials moved and placed throughout the year in a variety of weather conditions, whilst ensuring the tight specification of materials was managed efficiently throughout all seasons.

Eight cascading water attenuation lagoons with associated inlet and outlet structures were constructed in the £7.4 million project. The large-scale rainwater runoff storage solution has the capacity to store over 300,000 cubic metres of floodwater, which is the equivalent of 120 Olympic-sized swimming pools. The lagoons remain dry most of the time, enabling them to be farmed and crops planted.

The project was vital to protect homes and businesses in the area from future flood damage.
