Severn Trent’s tunnelling machine, Wiggle Blaster, has completed the tunnelling for a £60M water and waste improvement scheme in Newark.
The work is being carried out by the BNM Alliance, comprising of North Midland Construction and Barhale.
The Wiggle Blaster’s diameter is 2.1m and the tunnel is more than 200m long. It was named by local school children. The scheme will see new protection from sewer flooding and 15 miles of new and improved water and waste pipes.
The scheme is Severn Trent’s current largest investment in the East Midlands and work will continue until 2020.
Severn Trent programme manager Tim Sawyer said: “Thanks to the Wiggle Blaster, we now have tunnel over 200 metres that’s been created underground all without anyone knowing it’s there, minimising the number of roads we need to dig.”
