New £100m sewer is biggest in Scotland
Tunnel will relieve pressure in city’ s waste system
Scotland’s biggest sewer has opened after a £100 million construction project.
Water flows have started to run through the Shieldhall tunnel on the south side of Glasgow, which operators say will lead to fewer flooding incidents and better environmental conditions.
The three-mile long tunnel was constructed over two years by a team of more than 100 workers using a state-of-the-art tunnel boring machine. It stretches from Craigton to Queen’s Park via Bellahouston and Pollok parks.
Scottish Water said it will alleviate pressure on the existing waste water network, with 90,000 cubic metres of extra storm water storage.
The tunnel is the flagship project in Scottish Water’s investment in Glasgow’s waste water infrastructure and will reduce the risk of flooding, particularly in Mount Florida and Giffnock.
Douglas Millican, Scottish Water’s chief executive, said: “The city’s waste water infrastructure required major improvements to help transform it into a modern, integrated and sustainable system which will improve the environment and biodiversity on the River Clyde and help tackle flooding.
“As the Greater Glasgow areacontinuestodevelop, we are modernising our waste water infrastructure to support the needs of both existing and future customers. The completion of the Shieldhall tunnel is a key part of that network modernisation.”
Environment Secretary Roseanna Cunningham visited the Scottish Water control room yesterday and hailed the project as “extraordinary”.
She said: “The strategic importance of the Shieldhall tunnel as part of the ongoing investment across Glasgow by Scottish Water cannot be understated.
“Much underground of our infrastructure for water and waste water dates to the Victorian era.
“Communities across Glasgow will benefit for years to come from this latest extraordinary feat of engineering which lies hidden deep beneath the city. It represents the latest chapter in our collective aim to provide safe and sustainable ways of managing waste in our biggest city.”
It is part of Scottish Water’s £3.5 billion investment in infrastructure.
