Tunnelling Machine Named By Glasgow Pupil

Paisley TBM Naming Competition

Cruella de Drill

Nieve O'Hara was the winner of the competition to come up with the name for the Tunnel Boring Machine (TBM)

A Glasgow schoolgirl has won a competition to name a state-of-the-art tunnel boring machine (TBM) as part of Scottish Water’s multi-million-pound Glasgow Resilience Project.

Nieve O’Hara - a P7 pupil at Our Lady of the Rosary Primary in Cardonald – scooped top prize with ‘Cruella de Drill’ and paid a visit to the project site to see the TBM in person.

The hi-tech machine will be installing a 252 metre stretch of trunk main 20 metres beneath the White Cart Water and the Paisley Canal railway line in the Nethercraigs area of the city.

The project is being delivered by Scottish Water’s alliance partner Caledonia Water Alliance. Communication Manager Paul Milligan said: “It has been fantastic working with Our Lady of the Rosary Primary School. They have brought so much energy and excitement to the project.

“A big congratulations to Nieve who choose a fantastic winning name for our Tunnel Boring Machine.

“Also, a big thanks to their wonderful head teacher and teachers for allowing us to show them this innovative piece of engineering right on their doorstep."

The TBM will tunnel 20 metres under the White Cart Water

Concrete pipes that are 1500mm in diameter will be pipe-jacked into position at the rear of the TBM and a 900mm ductile iron water main will be installed inside. 

The work is expected to take about six weeks to complete.

The Glasgow Resilience Project will benefit almost one million Scottish Water customers by connecting the Glasgow area’s network with the system in Ayrshire to improve security of supply.

It will provide a two-way water supply between the Milngavie Water Treatment Works (WTW) system - which provides water for more than 700,000 people across much of the Glasgow area - and the Bradan WTW system which supplies more than 200,000 customers across much of Ayrshire. It will also benefit almost 50,000 customers in East Renfrewshire.

In the event of a disruption to water supply in either Ayrshire or Glasgow, the new system will allow millions of litres of water to be transferred in either direction, minimising the impact on customers if there is a burst main or other operational issue.

The project, which involves the use of innovative construction materials and techniques to reduce carbon emissions and power requirements, is being delivered for Scottish Water by Caledonia Water Alliance, our alliance partner, and is expected to be completed in 2024.
