At phase one consultation we proposed to use this site to drive the main tunnel up to the Hammersmith Pumping Station site and to then drive the main tunnel to the Tideway Walk site in Battersea. Since phase one consultation, we have identified Carnwath Road Riverside as our preferred alternative site over Barn Elms for the construction of the main tunnel. However, we still require a site at Barn Elms to intercept the West Putney Storm Relief CSO located there.
We are proposing to use the south eastern corner of the Barn Elms Schools Sports Centre for construction work and to accommodate permanent structures required to operate the main tunnel. The site would be used to connect the existing local CSO, known as the West Putney Storm Relief, to the main tunnel.
The location of the site is shown below. The Thames Path and River Thames are located to the east of the site. To the north are some of the Barn Elms Schools Sports Centre pitches and facilities. Putney Lower Common is located to the southwest. At the most southerly point of the site are Beverley Brook and the Beverley Brook footpath, which separate the London Boroughs of Richmond upon Thames and Wandsworth in this location. The site is adjacent to the Putney Embankment Conservation Area. The site also includes a maintenance site access road that would link to Queen Elizabeth Walk.

We have considered the comments from phase one consultation, feedback from ongoing engagement and new information; and undertaken further technical work. We consider that Barn Elms should remain our preferred site to intercept the West Putney Storm Relief CSO.
The site is located in the southern corner of Barn Elms, which is a good location because we can directly intercept the CSO. We also avoid having to construct pipes beneath the high pressure gas main and reduce encroachment into the playing fields.
The size of the site required at Barn Elms is significantly smaller than presented at phase one consultation, since we only need a site to intercept the CSO in this location. This means that the temporary effects on the playing fields would be reduced. We would no longer need to relocate the Scout Hut or divert the Thames Path. We would not need to construct a new temporary jetty and mooring structures, since the reduction in excavated material would not justify the associated costs and disruption.
