Crossness and Beckton Thermal Hydrolysis Plants


Due to an increase in population, the Crossness and Beckton Sewage Treatment Works needed a large upgrade to provide an improved sludge treatment capacity for the general population.

Tamesis, joint-venture of Imtech Process and Laing O’Rourke, were awarded the multi-million-pound project, contracting JK Fabrications Ltd as the design and build sub-contractor for the mechanical elements of the scheme. This included the design, manufacture, and installation of various diameter stainless steel pipework, ranging from Ø100mm to Ø1200mm.

JK Fabrications were also contracted to design, manufacture and install various sizes of mild steel de-sludge pipework ranging from Ø100mm to Ø1200mm and various sizes of inlet baffles.
