Paisley sewer TBM christened “Tunnelling Tanya”

School children in Paisley have named the tunnel boring machine (TBM) that will drive Scottish Water’s new interceptor sewer below the town as “Tunnelling Tanya”.

Contractor Amey will use the TBM, which is currently being built by Herrenknecht, to construct the 1.6km tunnel that will substantially reduce the frequency of spills from the sewer network into the Espedair Burn and White Cart Water in storm conditions.

Pupils from St Charles Primary School were set the challenge of coming up with the name and Hope Hunter’s suggestion of Tunnelling Tanya was selected as the winner.

The TBM is expected to arrive on site in August and will be launched from a shaft at Neilston Road where it will drive the 1.5m diameter tunnel at depths up to 27m below ground. Around 5,000t of rock is expected to be removed by the TBM during the drive.
