Lee Tunnel (Water)

The LEE Tunnel project is the largest British water engineering project for 20 years. This project involves the construction of a four-mile length of tunnel to prevent sewage discharges into the River Lee. The tunnel will prevent more than 16 million tonnes of sewage mixed with rainwater overflowing into the river from the Victorian sewer network when it becomes overloaded. The tunnel will store and then transfer sewage to Beckton Sewage Treatment Works, which is being expanded to deal with the increased treatment volumes.

PSuK won the contract for the 2 metre diameter pipeline to transfer the sewage and raw water into Beckton WWTW. Pipeline Protection carried out full maintenance on the three coat painted system according to ISO 12944 after full erection activities.
