Eppleworth Road Storage Lagoons

Following severe flooding in the urban area around Cottingham and North Hull, the East Riding of Yorkshire Council commissioned Mason Clark Associates to develop a scheme to mitigate flood risk to a large number of properties.

Mason Clark Associates undertook a feasibility study which included a detailed surface water model of the area. This established the volume of water flowing down the Raywell Valley and entering the urban area along Eppleworth Road. The proposals put forward a solution that utilised a series of water storage lagoons to collect the water flowing down the valley. Surface water flows into the lagoons by gravity and is only allowed to discharge at a very slow rate. The system is capable of storing 30,000 cubic metres of water and works automatically with no need for pumps or valve control. 

The lagoons were completed in 2010 and have been called into action twice already, demonstrating that flood risk has been reduced significantly.
