UK's largest inland flood defence scheme opens in Nottingham

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.

    It frequently seems surprising how cheap these flood defence projects are. At £45 million, within the grand scheme of things, the cost of this the largest inland project, is modest. 16,000 houses at, who knows, £100,000 each plus infrastructure and commercial/industrial property might be worth £3 billion. How many other worthy projects are waiting for EA funding to approach the value of long life capital stock at risk?
