Summary

The Thames Tideway Tunnel is a planned project to build a large sewer running under the River Thames. It is the Government’s preferred solution to the problem of spills from London’s sewers into the tidal part of the Thames. In response to correspondence, we explain the roles of the different parties, identify potential risks to value for money and set out what we expect good project management to look like. To avoid influencing the outcome of ongoing competitions for the construction and financing of the project, we do not evaluate the value for money of the project and the issues raised do not imply any audit judgement about its performance.
