Brentford Waterside Sewer Diversion

Barhale were required to install a new sewer system to facilitate the
construction of a mixed use residential and retail development, on a
4.79 hectare brown field site in Brentford, west London.
Barhale’s works involved the installation of 190m of new 600mm
diameter concrete pipeline, along with 6no 1500mm diameter
manholes along the run. This will enable flows from the new
development to tie into the existing Thames Water network.

All works were undertaken via open cut techniques. The pipeline was
installed at depths of between 3.5 – 4.5m throughout the site, using a
combination of methods, including:
• Drag boxes
• Trench boxes
• Trench sheets and frames
