Construction of Thames £5bn 'super sewer' almost complete after eight year project
London's £5bn ‘super sewer’ is almost complete after eight years, project bosses have revealed.
The Thames Tideway Tunnel is aimed at reducing the amount of raw sewage that flows into the river Thames.
The 16 mile long pipe will divert 34 of the most polluting sewage outflows that have been pumping into the river.
