The new London sewer project has taken a major step forward as the first of the Tunnel Boring Machines has been lowered into the ground at Battersea.
The two machines, have been put down over 50 metres into the ground at its Kirtling Street site close to Battersea Power Station.
The company building London’s super sewer, Tideway, are in charge of constructing a 25km sewer tunnel to tackle the huge problem of sewage pollution overflowing into the Thames.
The TBMS, Millicent and Ursula, named after pioneering women who lived and worked in London close to Tideway’s sites, will be used to dig the central of the Thames Tideway Tunnel.
Mark Sneesby, Tideway’s Chief Operating Officer, said: “The lowering of our first two Tunnel Boring Machines marks a significant milestone for the project before tunnelling gets underway later this year.
“London’s new super sewer will prevent tens of millions of tonnes of sewage from entering London’s iconic River Thames, the vein that runs through London, and will protect it for the next hundred years and future generations to come.”
The lowering of the TBM’s took approximately eight hours individually, with Ursula lowered on Wednesday, June 6 and Millicent on Tuesday, June 12.
When finished, each TBM will weigh in at 1300 tonnes and be 100 metres long and will be the project’s largest of six tunnelling machines, remaining underground for almost two years as they dig the tunnels.
