Thames Water has narrowed down to two its pool of potential contractors to rebuild and refurbish one of London’s largest sewage works.
The two contracting groups are Tamesis (a joint venture of Laing O’Rourke and Imtech Process) and AMK (Aecom, Murphy and Kier).
Both groups will now work with Thames Water in an ECI (early contractor involvement) process for four months before submitting their plans in March.
Thames will announce the winning contractor later in 2013.
Deephams sewage works in Edmonton, north London, was constructed in the 1950s and 60s, and much of it has come to the end of its useful life. It also needs expanding to cope with the projected population increase .
Thames Water capital delivery director Lawrence Gosden said: “We’ve chosen to involve contractors early in the design process in order to meet the significant challenges posed by a major project such as this. Once plans are submitted in March we’ll begin the final stage of our ECI process to choose a contractor to build the upgrade.”
