First Tideway TBM Breaks Through

TBM Charlotte, named after suffragist Charlotte Despard, is digging the Frogmore Connection Tunnel from Wandsworth to Fulham as part of the 25km Thames Tideway Tunnel project to protect the River Thames from sewage pollution.

She is working for the BMB joint venture of BAM Nuttall, Morgan Sindall and Balfour Beatty that is constructing the western section of the Thames Tideway Tunnel.The 1.1km Frogmore Connection Tunnel will take sewage overflows from King George’s Park into the main 25km super sewer at Fulham, where it will be transferred to east London for treatment instead of polluting the River Thames.

The 500-metre southern section of the Frogmore Connection Tunnel, from Dormay Street to King George’s Park, is now complete. Charlotte will now be lifted from the shaft, taken back to Dormay Street and placed back into the ground to tunnel 600 metres north to Fulham.
