Clugston wins contract package at Knostrop Waste Water Plant in Leeds

Posted: Friday 30th September 2016

Clugston Construction is pleased to announce that they have been awarded a £14.9m contract by the Amey Black and Veatch Joint Venture to provide Civil Engineering services at the Yorkshire Water, Knostrop waste water treatment works in East Leeds.

The multimillion pound investment by Yorkshire Water, when complete in October 2017, will treat 30,000 tonnes Dry Solids (TDS) of sludge annually and will process the sludge into a renewable energy source.

As part of the Knostrop Sludge Treatment Facility, Bio Gas produced by the anaerobic digestion process will power two CHP engines of 2000KW each, which will provide electrical power for the site or for export, dependent on demand. Any waste heat is recovered to heat the digesters and provide heat to the Liquor Treatment process.

Clugston's subcontracted package includes, ground preparation and stabilisation, involving recycling of existing concrete structures and installation of 300 CFA piles. This will be followed by construction of the foundations for tanks, control buildings and installation of ductile iron pipework and cable ducting.

Along with a new central process building, Clugston will also be responsible for installation of 15,000 square metres of link roads and 10,000 square metres of hard standing.

With the new facility located alongside the existing WTW, careful planning and safety management will be required.

Commenting on the contract Steve Radcliffe, Clugston's managing director said "it is really welcome news to have won this work in Leeds as it marks a return to the water sector after many years' absence."
