Completion of Beckton Sewage Treatment Works (STW) has moved a step closer since the take-over of Section Five having been granted at the site by Thames Water. Section Six – the final scope of the works – is expected to be completed by March 2015.
The works, delivered by a Tamesis - a joint venture between Imtech Water, Waste and Energy and Laing O’Rourke, includes the delivery of ASP4 which is a new activated sludge process stream designed to treat 30% of the 27m3/sec maximum flow to works. Three new odour control plants have also been installed, upgrades to 24 Final Settlement Tank scrapers (FSTs) and replacement of a further 48.
This is the fifth of six take-overs to be achieved on the scheme since the contract was awarded in 2009.
The £146m Beckton project is part of Thames Water’s Tideway Quality Improvement programme and one of five major sewage works to be upgraded in London. Already one of Europe’s largest sewage treatment works, the expansion of Beckton will enable the site to increase the population capacity of people it treats by 400,000.
Managing Director of Imtech Water, Waste and Energy, Duncan Atkins, commented: “We are delighted that Thames Water has granted Take-Over of Section Five of the Beckton STW Upgrade Project, which is now in its final stages. Tamesis is proud to have developed a scheme which, when complete, will allow for a population increase of up to 10% through to 2021.“
The final Section Six scope of works is due to be completed by March 2015 with the work comprising of a new Power Management System on ASP4.
