Roof pour caps off shaft at King Edward Memorial Park

Another shaft has been capped off on the super sewer at King Edward Memorial Park Foreshore - the first on the eastern section of the project.

The concrete cover slab signals the end of the main underground works within the shaft at the site in Wapping and marks more progress on the Thames Tideway Tunnel.

Work continues above ground including within the Combined Sewer Overflow chamber with the recent installation of the flap valves and secondary isolation gates and towards completion of one of seven public spaces along the River Thames to be left behind once the tunnel is operational. King Edward Memorial Park will be extended by eight per cent - or 2600 square metres - with new areas allowing visitors to get closer to the river.

This architecture and landscape work includes the installation of precast concrete river wall panelling which, thanks to its unique texture, will allow biodiversity to flourish in the area once the work is finished and the river walls are exposed to the Thames.  

The park is the location of one of the most polluting sewer overflows in London, which currently overflows the equivalent of more than 300 Olympic sized swimming pools into the Thames each year.

Work will also begin on removing the cofferdam, the temporary area of land built out into the river to construct the structures needed for the new super sewer. Once removed the shape of the new riverside public space and new river wall will become visible. 

From this site, the Thames Tideway Tunnel will carry sewage to Abbey Mills Pumping Station in Newham, and on via the Lee Tunnel to the Beckton Sewage Treatment Works to be treated.
