Tideway wanted to celebrate the completion of tunnelling of its 25km Super Sewer.
 
The tunnel was a feet of civil engineering and the start of the recovery of the Thames river ecosystem, but there was only a small window of time to physically enter it before it would be closed off to the public forever.
 
The sound acoustics within the tunnels are unique, so with our small window of opportunity, we helped create a Sonic Time Capsule of the space.
