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 experience 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 work is now underway at each of our 24 sites in London. Work is anticipated to be completed in 2024.
The tunnel will cost £3.8bn to complete, and an additional £1.1bn has already been spent by Thames Water for preparatory works. This cost 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.
