A three-mile long sewage tunnel will be built in the south of Glasgow as part of the biggest upgrade of the city's water network since Victorian times.

The £100m Scottish Water project will create the largest storm water storage tunnel in Scotland.

It will run between Queen's Park and Craigton industrial estate.

It will be big enough, in diameter, to fit a double-decker bus inside and more than five times as long as the Clyde Tunnel.

Scottish Water said the new waste water tunnel will resolve water quality and reduce flooding issues at key locations.

It will carry surface water such as rainfall and waste water from properties and provide storm storage during and after heavy rainfall.

The tunnel will be constructed using a specially designed tunnel boring machine, and will follow a route from the Queen's Park area towards Pollok Park.

It will then will head northwards under Pollok Park and beneath the M77 and Bellahouston Park, terminating at Craigton industrial estate where it will join the existing network.

It is part of a £250m, five-year programme of work aimed at improving the waste water network in the Glasgow area.

Geoff Aitkenhead, Scottish Water's asset management director, said: "The Shieldhall tunnel will resolve large-scale water quality problems in the River Clyde and its tributaries, provide aesthetic screening to overflows into watercourses such as tributaries of the Clyde and White Cart Water and reduce the risk of flooding in Aikenhead Road and Curtis Avenue in Mount Florida and Robslee Drive, Robslee Road, Robslee Crescent and Orchard Park Avenue in Giffnock.

"The tunnel will increase capacity and alleviate pressure on the existing network by providing additional storm water storage."

Work is expected to start in mid 2014 and take three and a half years to complete.
