Coppermills Water Treatment Works Upgrades

  • Sector:Water & Utilities
  • Client:eight₂O (SMB JV)
  • Location:Coppermills, Walthamstow
  • Value:£2.2m

As part of the upgrades at Coppermills Water Treatment Works,
Barhale were contracted by eight₂O to undertake the civil works for
the installation of 12 Rapid Gravity Filter Tanks (RGF Tanks), construct
a new weir chamber and pipework to two adjacent pipe galleries and
install new draw pits and ducting for HV/LV cables running into the
newly constructed MCC base slab. These upgrades will significantly
improve water purification capacity into Thames Water’s Ring Main,
and help to meet the demands of London’s rising population.

The scope of work on this project included all the earthworks for the
installation of the RGF Tanks and North and South pipe galleries. The
initial work plan required us to excavate the pipe galleries before
constructing the piling mat between them.
