Tideway’s construction work at Putney is now substantially complete and the new riverside area created as part of the project is now open to the public.
The completion of our work at Putney is an important milestone before the project ‘goes live’ in 2024. This is when the system will be switched on and will start to protect the Thames from sewage pollution for the first time. The tunnel is due to be fully operational in 2025, when it will prevent an estimated 95 per cent of sewage spills that currently overflow into the River Thames, improving the water quality for fish and other wildlife - and for people who use it for recreation and leisure.
At the Putney site we have:
Created a new riverside space with artworks inspired by the River Thames including a new bronze marker for the start line of the University Boat Race
Excavated a 36m-deep shaft and built a connecting tunnel to intercept the Putney Bridge Combined Sewer Overflow (CSO), linking it to the main sewer tunnel beneath the Thames.
Installed mechanical and electrical equipment to make the system run smoothly.
Although construction work is mostly complete, you may continue to see some Tideway staff as we work to bring the super sewer into operation. There will also be occassional periods when we need to close part or all the area while we undertake testing work for the sewer.
