THAMES TIDEWAY
Tideway , the company building London ’ s new super sewer , remains on track to deliver the project by 2025 , following the most substantial review of the programme since 2018 .
The new sewer is designed to capture more than 95 per cent of the sewage spills that enter the river from London ’ s Victorian sewer system . It will have a significant impact on the water quality , making it a much healthier environment for wildlife to survive and flourish .
The programme review , undertaken collaboratively by Tideway and key stakeholders including its main works contractors and Thames Water , looks at progress made on the project so far , taking into account the impacts of the Covid-19 pandemic , and provides an up-to-date picture of the future schedule .
With the remaining tunnelling , secondary lining of the tunnels and shafts , and the connections to the Thames Water sewer network progressing well , the verified programme provides confidence the project will be completed in 2025 .
Andy Mitchell , Tideway ’ s CEO , said : “ Working closely with our contractors and Thames Water has allowed us to look in detail at our progress so far and what we need to do going forward , to complete our project and start tackling sewage pollution in the River Thames as soon as possible .
“ This comprehensive review has reaffirmed confidence in our programme as we reach the end of the tunnelling phases and look ahead to the testing and commissioning stage . We are fully focused on delivering the Tideway project safely , at the right quality and to best value .”
Sarah Bentley , Thames Water CEO , said : “ This joint review of progress is a positive step forward in the delivery of the Thames Tideway Tunnel . Our teams are focused on working together to complete the project and bring the tunnel into service – so that it can do the vital job of improving the health of the river Thames and London ’ s environment .”
Tideway ’ s interim report confirms the programme review and the resulting c1 per cent increase in costs (£ 39m ). The project cost estimate is £ 4.2bn and the estimated £ 20- £ 25 annual cost range for Thames Water bill payers remains unchanged .
Key achievements in the period ? included the completion of shaft excavation on all sites and completion of 9.8km of tunnel
