The first valves at four of a total of 21 sites, which operate like giant gates, along the seven metre-wide tunnel have opened. The super sewer, which is 25km long, was connected to the 6.7km Lee Tunnel in May, completing the full London Tideway Tunnel network. Teams will work to connect the remaining discharge points to the new super sewer and test the entire system during different weather conditions, including heavy storms, Tideway said. Once fully operational, Tideway said the super sewer will almost eliminate the harmful effects of sewage pollution in the Thames through central London. Chris Weston, Thames Water chief executive, said: “This is a very exciting moment for us all as we see the third and final phase of the huge scheme to help prevent sewage pollution entering the River Thames.
