Putney Embankment Foreshore Overview The Putney Embankment Foreshore site is on the southern bank of the River Thames. There are two sites: a main construction site and an area to build a temporary slipway to maintain public access to the River Thames. This site will be used to intercept the Putney Bridge combined sewer overflow. 12

Putney Embankment Foreshore Overview The Problem: At this location, in a typical year, there would be 33 discharges of untreated sewage with a volume of about 68,000 tonnes into the tidal River Thames. The Solution: Our Putney Embankment Foreshore site will control the discharges from the Putney Bridge combined sewer overflow. When the tunnel is in operation it is expected that only one discharge will occur. Project Duration: Construction is due to be begin in 2016 and will take three and a half years. Site details: A temporary slip way will be constructed approximately 300m upstream of Putney Bridge. CSO drop shaft will have a depth of approximately 36m and an internal diameter of approximately 6m. 13
