Additional Info:

The site is a former oil refinery that is being developed as a natural gas terminal, receving gas from Qatar and distributing to the network in South Wales. The surface water design incorporates a detention basin being constructed within an existing ravine downstream of the intersection of the site drainage flows. The basin is designed to limit the outflow to an existing sea outfall to levels specified by the Environment Agency. The photographs below show the basin under construction. The concrete channel provides a route through the basin under dry weather conditions to convey flows arising from natural springs on the site through the basin.
