Thames Tideway Tunnel

A highly significant development for both London and the environmental sector, Thames Tideway Tunnel was the first project to be delivered under the new Special Infrastructure Project (SIP) regulations. It will be essential in preventing tens of millions of tonnes of sewage overflow discharging into the River Thames.  

Arcadis was appointed by Thames Water to perform due diligence testing for the project, thereby playing a vital role in assessing the health of the scheme on behalf of new funders being sought by Thames Water.  This enabled Thames Water to obtain the necessary funding to proceed, culminating in the transfer of the project to a new owner and funder in summer 2015. 

As a massive infrastructure project of significant importance, the scheme demanded the seamless blending of skills from across the Arcadis network, including:   

  • Funding Business Advisory, risk and project cost specialists from the UK
  • Water conveyance specialists from the USA
  • Tunnelling specialists from France
