Datchet Tunnel Relining

  • Sector:Specialist Skill

  • Value:£3.9m

Datchet Pumping Station (PS) is a key asset and up to 60% of London’s daily water demand can be met by the twin intakes from the Thames. When the decision was taken to switch it off, to enable Barhale (via the Optimise joint venture) to complete the essential Tunnel Relining project, Thames Water needed to grasp the opportunity to successfully complete all outstanding remedial work in the station at the same time.

The Datchet project is part of a programme of relining being carried out by Optimise. With 3km relining at Wraysbury and 1km from Queen Mother Reservoir to the pumping station already completed, the Datchet stretch will be followed by a 3km section from the Queen Mother to the outlet.
