New environment secretary Owen Paterson has opened the UK’s largest inland flood defence scheme - the Nottingham Left Bank Flood Alleviation Scheme.
Costing £45M, £6M less than the original budget, the flood defence runs 27km along the River Trent travelling through the city centre and through Attenborough Nature Reserve, a Site of Special Scientific Interest (SSSI).
Nottingham has a history of flooding dating back to 1683, and the new flood defence will protect 16,000 homes and businesses, along with roads and factories.
The scheme used a new trench-mix machine - a new technique where the original ground is mixed with cementitious grout to form an impermeable barrier without the use of traditional deep excavation methods. Using this technique saved £650,000 from the project, according to the Environment Agency.
The Department or Environment, Food and Rural Affairs funded the scheme which was built by the Environment Agency and contractor Jackson.
