Crossen's Drainage Scheme under construction, 1958.
Up until the 1900s, gravity was all that was needed to drain the land to sea. However, as the marshy areas dried, they shrank down below sea level. Since the 1920s, pumping has been used to take water off the land and out to the sea. Today's network consists of smaller drainage ditches and watercourses.
Crossen's Drainage Scheme completed, 1961.
Crossen's Pumping Station is one of the main stations used to pump water from the Alt and Crossens catchments into the sea. Supported by another pumping station at Altmouth (built in 1972), there are an additional nine smaller stations and hundreds of miles of drainage channels and watercourses.
