Millions of tonnes of sewage spills into the River Thames every year.
Tideway is building a super sewer to tackle this.
But we're also using the river on an unprecedented scale, by moving material from our tunnelling work using barges on the river...
...and using the spoil to create nature reserves!
Our largest barges keep around 93 lorries off London's roads!
...dramatically reducing our impact on London's air quality*...

...and local roads!
In fact, last year we kept 200 lorries off London's roads every day thanks to our use of the river!
