Putney Embankment Foreshore & Barn Elms

Tuesday 27th September 2016

Community Liaison Working Group (CLWG)

The CLWG will serve as a two-way communications channel between

Tideway and local communities.

CLWG will provide a forum for open discussion on matters concerning

construction and communications with local authorities and community

representatives.

The principal aims are:

• To promote communication across the communities affected

• To keep stakeholders, communities and businesses well informed about the

project’s progress

• To give the community an opportunity to express their views and influence

local communication activity

• Provide a forum for the local community to discuss, understand and

potentially influence the way we undertake construction activity

• In 2014, 62 million cubic metres of sewage discharged to the tidal River Thames.

• 50 discharges on average in a typical year

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 approximately 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.
