Major flood protection upgrade

24 Sep 2013

Scottish Water is to build a £100m sewer tunnel in Glasgow as part of the biggest upgrade to the city’s waste water network in more than a century.

The publicly-owned utility has confirmed that it is to construct a 3.1 mile sewer tunnel running between Queen's Park and Craigton industrial estate via Pollok and Bellahouston parks in the south of the city.

The tunnel, which will be the biggest storm water storage tunnel in Scotland, will resolve water quality and reduce flooding issues at key locations in the area.

It will be a major part of Scottish Water's £250m, five-year programme of work announced in February to upgrade the waste water network in the Glasgow area.

The upgrade is the biggest investment in the network since Victorian times and will improve river water quality and the natural environment of the River Clyde. It is being constructed to enable the Greater Glasgow area to grow and develop, alleviate sewer flooding and deal with the effects of increased rainfall and climate change.

The tunnel will be 4.65m in diameter, big enough to fit a double-decker bus inside and more than five times as long as the Clyde Tunnel. Work is expected to start in mid-2014 and take three and a half years to complete, including preparatory work, mine working consolidation and utility diversion work.
