Thames Water will work with Kier Group on a £66 million improvement project at Mogden sewage works to ensure the site can meet the demand of London's growing population.
The scheme, which will see Kier reconfigure the aeration lanes and replace air blowers, pipes and other equipment, will improve the resilience of the works in Isleworth, West London, and is part of the company’s comprehensive investment plan over the next four years to deal with increased demand across the region.
The work at Mogden, the third largest sewage treatment works in the UK which serves more than two million customers, will also see improvements to on-site energy generation, as well as laying the groundwork for further investment in the future.
A further £34 million investment by Thames Water to improve other assets at the site will bring the total spend to £100 million.
Francis Paonessa, Thames Water’s capital delivery director, said:
“Our investment in Mogden sewage treatment works will be essential in modernising one of our most urban treatment works.
“It will play an essential part in our work to reduce the impact on our neighbours, while ensuring Mogden can handle the expected increase in waste from London’s growing population in the future.
“This scheme is just part of a wider investment plan to ensure our sites can continue to provide our essential service to millions of customers across London and the Thames Valley.”
Mark Pengelly, group managing director at Kier Infrastructure, added:
“We have a long history of delivering projects and services for Thames Water and look forward to continuing our relationship with this project. It is a highly complex and specialised project and the team will be working in a live environment, across multiple locations of the site.
“We will be working with AECOM as design partners and we have selected key Kier and AECOM personnel for their experience and knowledge of STWs and complex large-scale civil engineering. They will bring a tried-and-tested approach, having collectively worked together over the past six years, at Deephams STW and Luton DART.”
Mogden has seen major investment in the last 15 years and the works now produces 60 per cent of its energy needs on-site.
The latest project is part of a 25-year investment plan to ensure the site meets the best environmental standards, including minimising the impact on nearby residents and reducing emissions across the business.
