Overall Project Update

Jamie Gray

Tunnel Boring Machine, Rachel, was launched from Carnwath Road in May 2019 and is making her journey to our Acton Storm Tanks site:

• Various planned stoppages in June/July/August to install temporary logistics railway and

full tunnelling set up (e.g. conveyor belt system)

• Distance tunnelled in a full productive week typically varies 130m-200m
• Total tunnel length = 6.9km, currently at 2.9km

Tunnelling – Carnwath Road to Acton

Updated information regarding tunnelling via email is being sent to residents every month since October 2019, and will continue throughout the project
