Thames Tideway Tunnel

What the Thames Tideway Tunnel does. Tideway Tunnel construction sites in Southwark

Storm water overflow is a major cause of poor water quality in urban rivers. When there's heavy rainfall, sewage goes directly into the River Thames.

A large-scale engineering project has begun to capture most of the storm water overflow and divert it into the Thames Tideway Tunnel, a massive holding tunnel under the Thames.

The waste water is pumped to Beckton Sewage Treatment Works to be treated before being released.

There are 3 construction sites in Southwark related to the Thames Tideway Tunnel:

  • Chambers Wharf
  • Shad Thames Pumping Station
  • Earl Pumping Station
