WHY DOES LONDON
NEED A SUPER SEWER?
Did you know, even a light drizzle of rain causes untreated sewage to spill into the River Thames from London's Victorian sewer network?
This adds up to tens of millions of tonnes every year.
Did you know, London's population is estimated
to increase to 16 million by 2160?
The super sewer is the solution
to tackle these problems
