Making Connections at Falconbrook

Making Connections at Falconbrook

A 15m-long tunnel connecting the shaft and interception chamber at Tideway's Falconbrook Pumping Station site has been excavated 20m underground.  

The team used an excavator to dig the 2m-wide tunnel, using sprayed concrete as the primary lining for the structure. 

Once the super sewer is complete, the tunnel will transport the pumping station's sewage from an interception chamber to the drop shaft, through which it descends to 40m below ground. From this level, a 220m connection tunnel will transport it to the main super sewer tunnel currently being constructed underneath the River Thames. 

With the tunnel excavated, the team will continue digging down within the shaft to a final depth of 40m.
