We're excited and inspired to be helping London build its future as a competitive city - creating a platform for economic growth and a more connected, vibrant and sustainable community.

An example Thames Tideway Tunnel

Transforming the ecology of London’s river

Once completed the Thames Tideway Tunnel will be Europe’s longest and deepest continuous tunnel, travelling 25km through central London to intercept untreated sewage discharges that spill into the tidal Thames and pollute the city’s iconic river. The Thames Tideway Tunnel will create a cleaner, healthier River Thames and improve the quality of life for all Londoners.
