Glan Agua's Tunnel Boring Machine achieved the (TBM) breakthrough at Thames Water Cockfosters Reservoir, which is part of a multi-million upgrade framework for Thames Water in partnership with Affinity Water to provide critical resilience upgrades to ensure ongoing water supply for essential projects. The TBM installed 120 metres of 1.2 metre diameter pipes to allow the successful transfer of 5 million litres per day (MLD) from Thames Water reservoir to the nearby Affinity Water Cockfosters reservoir.
