Nearly 170 years after Sir Joseph Bazalgette revolutionised the way water waste flowed through London, work has begun on the new 4.2bn super sewer which is urgently needed to halt the tonnes of sewage being spilt into the tidal section of the River Thames every year. Currently, around 10,000 tonnes of sewage related litter enters the tidal River Thames from CSOs every year. This will be reduced by 90% once the Tideway Tunnel is in operation in 2023.
In the last few weeks Tideway has reached a few key milestones, including the arrival of two more tunnel boring machines with diameters of 8.8 meters, weighing in at over 800 Tonnes. As well as this the acoustic shed has been erected, this allows shaft excavation to be more efficient.
It’s expected that Tideway will create nearly 5000 sustainable jobs and see almost 20,000 people working on the project in total. This includes aiming for over 400 workers to be apprentices, one in every 100 to be an ex-offender, and to have a 50:50 male-female split on the client team.
Currently, tunnelling work is well under-way and Tideway workers at the Chambers Wharf site have re-surfaced the site area and are now constructing the diaphragm walls for the shaft. Whilst contractor teams will aim to complete the project by late 2022, the rest of the scheme’s timeline looks like this:
2017: Tunnelling begins
2019: Secondary lining begins
2021: Tunnelling ends
2022: System Commissioning begins
2023: All works completed
If you're interested in working on this project, we'd be keen to talk to you. We are currently recruiting for a number of roles including CAD Technician and SCL Shift Manager. For more information on this positions, chat to Penelope Ware.
