Wolferton Pumping Station

Client – Kings Lynn Internal Drainage Board

This project was located within the Royal Estate at Sandringham in Norfolk and was to build a new storm water pumping station and river outfall culverts to replace the existing pumping station built in the early 1950’s.

The site covers land including a SSSI and an RSPB area seaward side of the floodbank and Sandringham Estate farmland. We worked closely with the Client Kings Lynn Drainage Board and the Environment Agency to reduce impact on the abundant wildlife and to preserve rich natural habitats.

The three new structures each consist of permanent cofferdams constructed from steel sheet piles up to 17 metres long with reinforced concrete capping beams and walls. The new main Drain Inlet structure houses 3 new electric pumps capable of pumping 4800 litres/second out to sea via 3no. 900mm diameter pumping mains. A second inlet structure controls the River Ingol which flows through twin 1.5 metre diameter culverts under the sea bank and out to sea. The third structure is a combined outfall which is designed to reduce the build-up of silt which currently hinders river flows.
