Tunnel construction complete on Scotland's biggest sewer

13/10/2017

The construction phase of Scotland’s biggest waste water tunnel, which will help tackle flooding and improve river water quality in the Glasgow area, has been completed.

A giant state-of-the-art tunnel boring machine (TBM) has spent 15 months creating the 3.1 mile-long tunnel or sewer beneath the south of the city and last night “broke through” in Queen’s Park. To see the breakthrough of Daisy the TBM watch the video here. - Scottish Water. 41/17
