Environmental charities and amenity groups have backed the government’s decision to approve construction of the £4bn ThamesTideway Tunnel.
The Thames Tunnel Now coalition – which includes WWF, River Thames Society and London Wildlife Trust among others – said the super sewer would improve the river’s health immensely.
Thames Tideway Tunnel chief executive Andy Mitchell said the tunnel would have captured 97% of the sewage that poured into the Thames last year.
Debbie Leach, chair of Thames Tunnel Now, said: “We welcome the government’s decision to give the go-ahead for the Thames Tideway Tunnel. It will prove invaluable for the health of the river.
“Like me, thousands of Londoners use the river for rowing, angling, sailing and canoeing. Walkers and cyclists use the towpaths, and people often venture unknowingly on to the foreshore where sewage is currently deposited.
“The Thames Tideway Tunnel is the most important piece of the jigsaw that will once and for all clean up London’s river and encourage even more Londoners to connect with the Thames. We praise politicians of all parties for keeping their nerve and supporting a key environmental project which will see the end of ‘London’s dirty secret’.”
