‘Mission Impossible’ sewer repair wins UKSTT award

A sewer repair in Skegness dubbed Mission Impossible, carried out by Danaher & Walsh’s dedicated Anglian Water team, has won a UKSTT Award.

The project won the Pipe Rehabilitation – Non CIPP award, which was presented at a ceremony last night.

UKSTT – the United Kingdom Society of Trenchless Technology – is the de facto industry body for no-dig technology in the UK, whose aim is to advance the science and practice of trenchless technology for the public benefit.

Their annual awards celebrate innovation and excellence throughout the industry.

The winning project involved repairing the collapse of a 300mm diameter sewer, 4m below an entertainment complex in the busy seaside resort of Skegness. To add to the challenge, the pipe was completely full of rubble, brick, paving stones and metal debris.Following bench tests, a system was devised using a resin to bind the debris together, allowing it to be robotically cut from the pipe. The resin was injected by running a small bore pipe through a custom inflatable packer.
