Mott helps with upgrade
A joint venture of Galliford Try and Biwater has contracted Mott MacDonald as the detailed civil engineering designer for Thames Water's £40M Long Reach Sewage Treatment Works upgrade.
The project will provide additional treatment processes at the works in Dartford, Kent, to improve the quality of treated effluent returned to the River Thames and to meet new Environment Agency standards. The improvements will also enable the plant to generate more renewable energy from the sewage treatment process – enough to power over half the site.
Mott MacDonald will manage the detailed civil, structural and geotechnical design for the construction stage of the project.
The works is situated close to the tidal stretches of the River Thames. With groundwater close to the surface and pressure in the water table varying with the tide, work on this project is expected to be challenging, requiring expertise and careful planning.
Mott MacDonald project director David Thomas said: “We are delighted to take on such an important role in this significant project.
Mott MacDonald has extensive experience in structural design as well as providing
safe, innovative and sustainable solutions for all aspects of wastes and resources management.”
The Long Reach project is due for completion in 2012.
