The 3.1 mile-long structure, which is claimed to be the largest wastewater storage tunnel in Scotland, will run between Queen’s Park and the Craigton industrial estate.
The £100m tunnel has been designed to enhance water quality, address the city’s flooding risks and reduce the pollution of the River Clyde.
Under the contract, the JV will build two 15m-diameter shafts, each 20m deep, a 300m-long cut-and-cover trench and a 5km tunnel with an internal diameter of 4.7m.
Vinci said the technique utilized will be that of a mud pressure type tunnel boring machine.
A specially designed tunnel boring machine will be used to build the project whose route has been selected to minimise disruption.
Construction work, which will commence in October 2014, is expected to be completed in early 2018.
Scottish Water is transforming the Greater Glasgow area’s water and waste water systems through a long-term investment programme.
As part of its plans, the company is upgrading several miles of water mains to improve security of supply and reduce the risk of bursts and inconvenience to customers.
The company is also upgrading the Greater Glasgow area’s waste water network into a new sustainable drainage system which will improve the environment of the River Clyde and its tributaries.
