Queen Elizabeth II Reservoir Tunnel Relining

The Queen Elizabeth II (QEII) Reservoir is a raw water reservoir in
South West London that is owned and operated by Thames Water.
The reservoir holds over 19 million litres of water, equating to 10% of
the raw water storage for London. Once treated, this provides clean
drinking water for millions of people across Surrey and London.

Barhale were engaged by Thames Water to complete this £11m tunnel
relining project to guarantee the integrity of the aged inlet and outlet
tunnels. The goal of the project was to strengthen the tunnels and
prevent any leakage at this crucial clean water asset.
