Deep Tunnel Super Pumps Pushed to the Edge in London's Lee Tunnel
/The problem is big.
An average of 39 million tons of sewage flow each year from the 35 most polluted combined sewer overflows (CSOs) in London—currently part of a 150-year-old Victorian network that can no longer accommodate the excess sewage and rainwater.
The challenges to solve the problem are even bigger—a pump station buried 85 meters below the surface in a shaft 32 meters in diameter.
At the heart of the solution are big pumps—54-ton Super Pumps specifically created by KSB to operate within a complex, carefully-engineered pumping system.
