At the beginning of this month TBM Charlotte completed her journey to the Carnwath Road reception chamber at Fulham, finishing a 1.1km connection tunnel, at a depth of 30 m. It will take sewage overflows from King George’s Park into the main 25km tunnel at Carnwath Road, where it will be transferred to east London for treatment instead of polluting London's waterway.

Charlotte is one of the project’s smaller TBMs, measuring 3 m wide and more than 70 m long and is named after suffragist Charlotte Despard. She was the first to break through the ground to complete a section of tunnel for London’s new super sewer in October.

Having dug the 500 m southern section of the Frogmore Connection Tunnel, from Dormay Street to King George’s Park, she was then hoisted from the shaft, taken back to Dormay Street and put back into the ground to tunnel the final 600 m to Carnwarth Road.
