Reconnecting London with the River Thames

London's super sewer is now protecting the river from pollution.

We’ve switched on the new super sewer which is now doing its job to clean up the River Thames. Every time it rains, our hi-tech computers are calculating how much of your sewage is filling the tunnel networkinstead of spilling into the river. A good job well done (even if we do say so ourselves).

What is a cubic metre (m³)?

1,000,000m³ is the equivalent of 400 Olympic-sized swimming pools, which if you put out in a row would stretch for 20km!
