  Modern pumping station
  The modern pumping station (Station F) was designed by architects Allies and Morrison. The original building (Station A) has electrical pumps and these are used to assist the modern pumping station during high flows if required.
  It is one of the three principal London pumping stations dealing with foul water.
  Both pumping stations are able to discharge flows directly into the Lee Tunnel.
  Lee Tunnel
  The Lee Tunnel is a sewage tunnel that runs from Abbey Mills to Beckton Sewage Treatment Works and is designed to handle the 16 million tons of overflow sewage that was previously discharged into the River Lea each year at Abbey Mills, as well as the additional wastewater brought to Abbey Mills by the Thames Tideway tunnel. Construction of the Lee Tunnel began in 2012 and it was opened for service in early 2016.
  Thames Tideway Scheme
  Abbey Mills is the endpoint of the main Thames Tideway tunnel, where sewage will be transferred into the Lee Tunnel and onwards to Beckton for treatment. Both the Lee Tunnel and the main Thames Tideway tunnel also serve as storage reservoirs to store wastewater during heavy rainfall.
