Geological Institute contribution

Hydrogeological data

  • Five confined aquifers of thickness from 1 to 12 m are revealed.
  • Piezometric level is about 1 m below the surface.
  • Mine water temperature is 15-16 C.
  • Expected groundwater flow rate is upto 70 l/s.
  • Hydraulic conductivity is within the range of 0.22 - 8.60 m/d.
  • Specific discharge varies from 0.05 to 0.10 dm3/s.m
  • Total dissolved solids (TDS) is above 1 g/l.

  • Assessment of exploitation

    Assessment of geothermal heat exploitation from mine water for the use of heating buildings

    Energy, Sustainable urban plan, Business case and Implementation plan would be carried out together with Bourgas Municipality.
