Posted: Monday 26th July 2010

AECOM has successfully bid with contractor J Murphy & Sons to design improvements to Thames Water’s Deephams sewage treatment works, which serves almost one million people in North London.

The £35m design and build project to improve the water quality of the River Lea by reducing sewage overflows will involveupgrading and enlarging the existing inlet works, boosting the storm capacity of the plant to deal with anticipated storm capacity for 2026.

The main features of the AECOM design are:

Tenderers had to place their submissions by “e-tendering” on Thames Water’s online extranet for the design and build scheme. AECOM is responsible for design of civil, structural and hydraulic elements of the contract. Work on site is now under way and planned for completion in March 2012, in time for the London Olympics. A second phase of the works will concentrate on upgrading the treatment processes on the existing high level sewers into the works.

“We are delighted to be working as part of the J Murphy and Sons team to deliver this significant project for Thames Water”, says Raoul Nardin, AECOM project manager. “This joint provision of services changes the focus of design to achieve higher efficiencies, whilst using valuable AMP4 experience to achieve the engineering excellence our clients are used to. As Thames Water turns toward design and build contracting in AMP5 in order to get best value, so we are aiming to work with contractors to provide that value”.
