Glasgow’s underground observatory takes temperature of city’s mine water

The UK Geoenergy Observatory in Glasgow has completed a first survey of the water circulating in abandoned mines lying up to 88 m below the city.

Scientists completed pumping tests and collected samples from 10 of the observatory’s 12 boreholes, which range from 16-199 m deep and are fitted with hundreds of state-of-the-art sensors.

The survey has yielded important baseline data on the status of the mine systems.

The results also confirm that scientists will be able to use the boreholes to better understand how thermal energy in mine water could be used as a renewable energy source for homes and industry.

Notes to editors

Where is the Glasgow Observatory?


About the 12 boreholes

The boreholes range in drilled length from 16 to 199m. They have been positioned so that scientists can:

  • extract 180 m of rock core samples
  • build up an accurate model of the geology below
  • measure water temperature, flow and chemistry underground
  • model the underground water systems
  • measure the potential for mine water heat energy and heat storage
  • provide baseline information on soil and surface water chemistry and ground gases nearby
