ON 04/12/2020 the TBM Annie which is 6.4 m wide, 100m long and 960t in weight - began driving the 4.5km connection tunnel between Greenwich Pumping Station and the main super sewer at Chambers Wharf. 

The TBM, smaller than the main tunnel TBMs, will continue past sites in Deptford and at Earl Pumping Station on its way to Bermondsey.  

Named after Annie Scott Dill Russell, the first female scientist to work at the Greenwich Observatory, the machine was initially assembled at a site by the O2 Arena having been shipped from Germany before being dismantled and transported via local roads.  

With the marine infrastructure in place at Phoenix Wharf, the northern half of the site in Greenwich, much of the excavated spoil will be removed from site by barge – in line with Tideway’s commitment to move material by river where possible. For archive information please click here and uk/54.
