Thames Water this week named the two contracting groups it will work with to design and build an upgrade for its massive Deephams sewage treatment works innorth London.
The two joint ventures are Tamesis (Laing O’Rourke/Imtech Process/Imtech Process) and AMK, a joint venture between Aecom, Murphy and Kier.
The company will spend the next four months working with the groups on their designs before announcing which has won thecontract in early 2013.
Deephams is one of the country’s largest sewage treatment works and handles around 200Ml of wastewater a day.
The upgrade is needed to comply with the requirements of a discharge consent that is due to come into force in 2017, as well as to cope with population increase.
Thames Water has opted for an early contractor involvement (ECI) approach, hoping this will result in innovative solutions to enable the upgrade to be completedwhile the existing works remains in operation.
“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.
“Early involvement maximises the time for innovative solutions to be developed,” said Thames Water capital delivery director Lawrence Gosden.
“Innovation, collaboration and sustainability are the three pillars by which we want to deliver this project and we’re excited to see what Tamesis and AMK come upwith,” he added.
