Construction has started on Scotland’s biggest waste water tunnel, using a tunnel boring machine named Daisy.
The Shieldhall Tunnel will be constructed for Scottish Water by the Glasgow Tunnel Partnership, run by a commercial joint venture between Costain and Vinci Construction Grands Projets called CVJV.
The £100M tunnel measures 5km in length and forms a key part of Scottish Water’s £250M five-year programme of work to enhance river water quality and the natural environment.
The 1,000t TBM being used for the projects measures 180m in length and will commence construction on the tunnel between Craigton and Queen’s Park. The machine was named Daisy the Driller by Lewis Bennett of Craigton Primary School, through a competition run by Scottish Water.
The TBM is expected to complete its journey and emerge at Queen’s Park after nearly 13 months, when the new tunnel will be connected to the existing network.
The cabinet secretary for environment, climate change and land reform Roseanna Cunningham has launched the tunnel boring machine (TBM) for the project.
Scottish Water CEO Douglas Millican said: “The Shieldhall Tunnel is the biggest of many projects which are progressing deep beneath the Greater Glasgow area’s streets largely out of sight of most people who live, work and travel here.
“Much of the existing waste water infrastructure was built in Victorian times and the modernisation of the system and construction of new underground assets such as the Shieldhall Tunnel will enable Greater Glasgow to realise its above-ground aspirations.”
The project is expected to be complete by the end of 2017.
