The GBM joint venture of Galliford Try, MWH Treatment and Mott MacDonald, been awarded a suite of contracts worth £80m under its current AMP5 framework contract with Thames Water.

The largest of the schemes, worth £28m, involves the development of sludge treatment and storage facilities at three waste water treatment works at Camberley, Chertsey (both in Surrey) and Crawley (West Sussex) so that they comply with the Nitrate Vulnerable Zone regulations.

The other major scheme in the suite, worth £27m, is to modify processes at Deephams waste water treatment works in Edmonton (north London) to facilitate the removal of phosphates and improve sludge treatment at the site.

Ultimately aimed at improving the quality of river water and sludge production, the schemes will be undertaken as part of the AMP5 framework contract with Thames Water awarded in April 2010.

Greg Fitzgerald, Chief Executive of Galliford Try, commented:

“We are delighted to secure this additional business from an existing framework client. It builds on our track record in delivering both clean and waste water infrastructure projects. Galliford Try is one of the UK’s leading infrastructure contractors to the water industry, working under five-year asset management programmes as well as on single projects for seven of the country’s major water utility businesses.”
