Cruella de Drill prepares to tunnel in Glasgow

16 October 2023


A Glasgow schoolgirl has won a competition to name a TBM to be used for Scottish Water’s Glasgow Resilience Project.

Nieve O’Hara, a pupil at Our Lady of the Rosary Primary in Cardonald, took the prize with the name Cruella de Drill.

The TBM will install a 252m stretch of trunk main 20m beneath the White Cart Water and the Paisley Canal railway line in the Nethercraigs area of the city.

Concrete pipes 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 system, which provides water for more than 700,000 people across much of the Glasgow area, and the Bradan Water Treatment Works system, which supplies more than 200,000 customers across much of Ayrshire. It will also benefit nearly 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.

The project is being delivered for Scottish Water by Caledonia Water Alliance, a Morrison Water Services and Aecom joint venture, and is expected to be completed in 2024.
