The new structure will consist of bored pile foundations with concrete base incorporating the Volute forms which direct the water into and out of the pumps. A reinforced concrete structure will be built to support the pumps and contain the fuel tanks and generators - one for each of the six pumps. A steel frame structure will be built on top of the concrete works to house the control systems, office and welfare facilities. The front of the building will be fully glazed to show-off the magnificent pumps - the second biggest in Europe.
CofferdamTo build the new station we have to install what is known as a 'Cofferdam.' But what is a cofferdam?
But why do we need a cofferdam?
The existing pumping station has to remain operational.
The new pumping station has to be on the line of the existing channel.
It keeps the North Sea out of Norfolk.
