What happens to the millions of tonnes of excavated material resulting from the digging of London's Super Sewer? Wet civil engineering firm Land & Water's Habitat Creation Scheme in Rainham is using repurposed material from the Thames Tideway Tunnel project in order to create wetlands and encourage species cultivation along the Thames corridor.

Land & Water has used sustainable transport to ship over 1.4 million tonnes of spoil from the east and west sections of the tunnel in order to use both the clay and chalk to create an environment that can harvest its own water, attract new species, provide environmental research opportunities and biodiversity benefits. 

Land & Water will be operating the restoration scheme until 2042, resulting in over six million tonnes of wet and dry spoil material being repurposed and 110 hectares of valuable nature habitat being created.
