As part of the AMP7 Tunnels and Aqueducts Programme, Barhale inspected and repaired the 6.8km long Thames Water Ring Main (TWRM) section between Battersea and Barrow Hill.

The team replaced or removed pressurised assets on the main, and successfully repaired leaks at over 73 locations, during an outage closely coordinated with Thames Water. The works were completed within budget and programme, and with zero lost time injuries over 3081 man-hours despite the high risk nature of the works.

The 2.65m diameter wedge block tunnel was 6.8km in length. As part of the scope of works, Barhale were contracted to replace or remove pressurised assets.
