Project Update 17/12/2025

Hi everyone,

As we move towards the festive period, we wanted to bring you an update from site and a look ahead to the next couple of weeks.

Work continues on multiple fronts, with teams working across the site to make best progress.

West of the roundabout

• This week, we anticipate completion of pipelaying, and re-surfacing work to be carried out on the westernmost stretch of the water main, representing another target date successfully achieved within the current programme.
• Work will then start on creating the working area that will eventually allow us to carry out the necessary connection into the existing main.
• Work continues with the pipelaying between that section and the western end of the roundabout area.

East of the roundabout

• We continue with enabling works for the microtunnelling process that will allow us to install the pipes nearest the roundabout in a way that navigates a number of other utilities and culverts.
• This section of pipework will connect the pipes we have already completed laying on the most easterly section, and within the roundabout area.
• The team carrying out the microtunnelling will continue to work through the festive period, with the exception of December 25, 26, 27 and 28.
• While the later stages of the microtunnelling will involve periods of 24 hour working to make best progress, we do not anticipate noise disruption. We will be utilising noise barriers and working within regulated parameters.

We will continue to work closely with our partners, Galliford Try, and with TfL, Costain and all other parties involved, to keep pressing ahead so that we can make best progress, safely and efficiently.

Many thanks for your patience during this challenging and complex project in 2025, and we look forward to a successful completion in Spring 2026.
