Tideway is the company delivering the Thames Tideway Tunnel. It is owned by a consortium of investors, and more than two million pensioners have an indirect investment in Tideway through UK pension funds managed by those investors.
More than 400 highly experienced professionals are employed by Tideway to deliver the project, working alongside the company’s four main delivery partners.
Preparatory work on the project began in 2015 and construction is now underway at each of our 24 sites in London. The project is anticipated to be completed in 2025.
The tunnel will cost £4.4bn to complete. The cost of the project is being paid for by Thames Water’s 15 million wastewater customers through their bills, which will rise by no more than £25 per year.
