The Shieldhall Tunnel will be Scotland’s largest waste water tunnel, 4.70m in diameter and 3.1 miles long, and will form part of the biggest upgrade of Glasgow’s waste water network in more than a century.

The tunnel will run between Queen’s Park and the Craigton industrial estate, and will resolve water quality and reduce flooding issues at key locations in the area served by the Shieldhall Waste Water Treatment Works.

Work will start in October 2014 and completion is anticipated in early 2018.
