The second TBM has arrived onsite to start boring a large interceptor sewer in Paisley.
Working alongside Donegan Civil Engineering, Scottish Water contractors Amey are constructing the large interceptor sewer in Paisley which, once completed, will substantially reduce the frequency of spills from the sewer network into the Espedair Burn and White Cart Water in storm conditions.
The 23t Herrenknecht TBM has a 1.5m diameter, and will 1.5km tunnel at depths of up to 27m removing 5,000t of rock as she makes her way under Saucelhill Park in Paisley.
The project will improve the river water quality in the two watercourses and, in turn, the River Clyde.
Local pupils from St Charles Primary welcomed the TBM from Germany onto site. The children heard about the project and saw the TBM up-close.
The project team ran a competition at the end of last year’s school term asking pupils to come up with a name for the TBM. It was Hope Hunter who won with ‘Tunnelling Tanya’.
Scottish Water project manager Brian Boland said: “We’d like to thank you all for coming along today to help mark this important milestone for the project. We’re sure you’ll join us in wishing Tunnelling Tanya well as she sets to work, tunnelling for around eight weeks before emerging at the other side of Saucelhill Park. She’ll undertake the longest drive on this project.”
Paisley’s MSP George Adam added: “It’s not every day you get to see a tunnel boring machine in Paisley – it was a fascinating visit for us all.
“I’m extremely encouraged by the enthusiasm shown by the pupils; they’re so keen to learn and perhaps having had the chance to find out about this major engineering project will spark their interest in a future career in engineering.”
The investment, which is the biggest of its kind Scottish Water has ever made in Renfrewshire, is part of the company’s £250M, five-year programme of work, launched in 2013, to improve river water quality and the natural environment and tackle flooding across the Greater Glasgow area.
