With only a week until the Thames Water consultation on London’s new “super sewer” closes campaigners are determined their views about Barn Elms being listed as a possible sewer entrance site are heard.

Members of Stop the Shaft (STS), a campaign group of Putney and Barnes residents, have urged neighbours to the proposed site to have their say and have been hand-delivering 10,000 feedback forms to people in the area.

STS spokeswoman Sian Baxter said: “It is absolutely vital every individual submit their feedback before the deadline and we are urging people not to be complacent. We strongly believe a number of environmental, social and historic benefits of the local area will be desecrated forever if people fail to act and voices are not heard.”

Objections to building a tunnel entrance, which would allow workmen access to the new super sewer, on the Barnes and Putney border were raised last month when Thames Water announced a plot of land on the southern edge of the picturesque Barn Elms playing fields as its preferred site for development.

Residents on both sides of the land raised concerns over what such a build would mean for neighbouring communities, saying the required three years of 24-hour-a-day construction work would be unacceptable.

They also questioned the way the water company had notified them of the consultation process for the site, which led to an extended consultation period for residents to have their say.

The Thames Water consultation ends at 5pm on January 14.
