The subway network is built in Glasgow’s old Victorian tunnels, and because the train lines intersect two major rivers, it is subject to significant leakage.
The waste water can be turned into energy-efficient heat, and the pump technology is already used for heating homes.
Some experts have claimed as much as 40 per cent of Glasgow’s energy could be provided from geothermal heating using waste water from old mineshafts.
The study is expected to deliver its first results by the end of May, and SPT Chief Executive Gordon Maclennan said: “The potential of exploiting waste water in Subway tunnels to turn it in to power is very exciting.”
