Inside London’s new hidden underground ‘super sewer’

#environment #britain #rivers
The Thames Tideway Tunnel - a colossal 15-mile concrete tube stretched out under London - has promised to return nature to the longest river in England.
The “super sewer” will stop some 40 million tonnes of sewage ending up in the river each year, bringing an end to centuries of pollution.
The tunnel is almost finished, and ready to stop an annual 40 million tonnes of sewage spilling into the Thames, helping to transform the capital’s river and make the water fit for the return of otters, fish and even seals.
