From "Gallows Corner"
Go to the project
Hi all,
We wanted to bring you the latest from site, as we work through the remaining crucial elements of our water main diversion work at Gallows Corner.
You may have seen the updates from TfL on the overall programme earlier this week.
In that, we highlighted a number of vital and complex stages that we needed to get past, to help us keep on track for completion of our work, within the overall Gallows Corner programme. These pieces of work need to be carried out with the greatest care, to ensure we maintain water supplies for the communities served by this part of the network, and to leave behind a reliable and resilient water pipe, once this project is complete.
The first two of these pieces of work were connections into the existing pipework. These had to be carried out “under pressure”, which means drilling into that large water main while water was still passing through it.
Our aim was to carry out these two connections by late February, and we are pleased to say that they were both completed this week.
This allows us to continue pressing ahead with the construction of large, reinforced anchor blocks, which will protect the main once it is in operation, and the pipe testing processes that will follow.
We will continue to liaise closely with all partners on site to complete this complex piece of engineering. Thank you, as always, for our patience and understanding.
