A Galliford Try team has been awarded a £60m 'odour improvement' contract at one of Europe's largest sewage sites.
The GBM joint venture comprises Galliford Try, Biwater Treatment and Mott MacDonald.
Permanent covers will be installed over all 16 primary settlement tanks - the most odorous part of Beckton Sewage Works in east London, which covers an area the size of ten football pitches.
Odour-control units, which scrub clean outgoing air to remove odour, will also be installed at the site.
Work will start in March 2011 and is due for completion in 2015.
Steve Shine, Thames Water's chief operating officer, said: “This project will reduce odour emissions by around 70% by 2015, making a substantial difference to local residents.
“As well as covering the settlement tanks at Beckton, we are going to install special odour-eater machines to gobble up the smelly air which sometimes comes off them.
“We have earmarked more than £350m to improve Beckton over the next five years in order to serve the future needs of London and deliver significant environmental benefits.”
In March 2010, Thames Water started work on a separate four-year scheme at Beckton Sewage Works, to help clean up the River Thames.
The major upgrade will enable the site to treat 60% more sewage, so it can better cope with heavy rainfall, helping to prevent the sewage works being overloaded and discharging into the river. This work will be completed in 2014.
GBM already secured £280m worth of other work under the AMP5 framework.
