being delivered by a joint venture of Ferrovial Agroman UK and Laing O'Rourke. The east region is being delivered by a joint venture of Costain, Vinci Construction Grands Projets and Bachy Soletanche.
System integration is being delivered by Amey, which is responsible for providing process control, communication equipment and software systems for operation, maintenance and reporting across the Thames Tideway Tunnel system.
The project is due to be fully up and running (with testing complete) in 2025. Thames Water will then operate the system, as part of its London wastewater network.
Chris Weston, CEO of Thames Water said: “This is a very exciting moment for us all as we see the third and final phase of the huge scheme to help prevent sewage pollution entering the River Thames. We recognise no single body has the ability to achieve this vision alone and are keen to continue our work with partners to meet expectations of the community and the environment.
“The Thames Tideway Tunnel, a £4.5bn investment made by our customers, is nearing completion. We are already seeing the benefits of our £700m investment in
Lee Tunnel in 2016, and the Channelsea River and River Lea now have ‘good to excellent’ water quality as a result – showing how the Thames Tideway Tunnel is set to bring further improvements in central London.
“We have published plans to upgrade over 250 of our sewage treatment works. In London, we have started the £100m upgrade of Mogden sewage treatment works, and we’re also spending £145m upgrading Beckton sewage treatment works, which will increase capacity and reduce the number of storm discharges.”
Chris Coode, CEO of river charity Thames21, said: "We are delighted to see the Thames Tideway Tunnel is coming into commission. This critical infrastructure will play a significant role in protecting the tidal Thames from the damage caused by sewage pollution, a step toward improving the health of the river in central London.
“We hope this major project will inspire the rapid implementation of other solutions, to restore and protect our rivers. Much work remains to be done across the wider Thames Basin to address the full range of sewage challenges."
Water Minister Emma Hardy said: “The
Thames has defined the capital and the nation, but like so many of our waterways it has been degraded by unacceptable levels of pollution.
“Our reforms of the water sector will fundamentally change how our water system works and clean up our waterways. The Thames Tideway Tunnel is an example of the transformation and investment we want to see up and down the country to clean up our rivers, lakes and seas.
“This is an important milestone with the first sections in action and already reducing the level of sewage pollution in the Thames.”
Environment Agency Chair Alan Lovell said: “We are proud to have worked collaboratively with partners on the Tideway project reducing storm sewage spills into the tidal Thames by around 95%.
“Our contribution ensures that the best possible environmental outcomes are achieved; we are confident that the project will markedly improve the river for wildlife and for people.
“We are regulating the system with environmental permits and will continue to monitor water quality and aquatic life in our capital’s river.
Trio land £540m Southern Water sewer deal
Southern Water has awarded contracts worth up to £540m to three companies to boost its wastewater network performance.
The winning contractors will be responsible for delivering essential frontline sewer services from responding to emergency calls to rehabilitating existing sewers.
Work will be carried out across four lots.
Maintenance and manholes workstreams will be the responsibility of Lanes Group, while Cappagh Browne will deliver on sewer rehabilitation projects, and McAllister Bros on sewer sealing.
The contracts will start in April 2025, spanning all five years of the spending period known as AMP8, with the potential for extensions.
Southern Water’s Head of Wastewater Networks, Alex Saunders, said: “We are delighted to have secured partnerships with industry leading suppliers who are experts in their respective technical disciplines.
“These agreements prepare Southern Water to meet the service levels expected by our customers and will help us to deliver on our environmental improvement ambitions for years to come.”
