AECOM joint venture awarded US$285.8-million contract by Thames Water

AECOM announced today that a joint venture in which it participates was awarded a US$285.8-million contract by Thames Water to rebuild Deephams Sewage Treatment Works, one of London’s largest sewage works facilities.

AECOM and joint venture partners Murphy and Kier will provide upgrade services to Deephams in order to meet new environment agency sewage treatment standards without disrupting the facility’s current operation.  The project will improve the water quality of London’s River Lee, increase capacity to allow for future rises in population and significantly reduce the frequency and intensity of odor on site.

“Our team’s creative, sustainable and cost-effective approach is an example of how AECOM can enable a client like Thames Water to meet complex challenges with energy-neutral solutions,” said AECOM Chairman and Chief Executive Officer John M. Dionisio.  “We are honored that AECOM will be contributing to one of the biggest infrastructure projects in the United Kingdom’s water industry.”

Work on the project is set to begin immediately by preparing for the planning application, which is expected to be submitted during summer 2014.
