Closed Loop Geothermal Systems

Closed loop systems do not extract groundwater from the heat reservoir (formed by layers of soil and rock). In these systems the ground collector takes the form of a loop of pipework in intimate contact with the heat reservoir through which a heat transfer fluid is circulated. As the heat transfer fluid travels through the ground collector it gains or loses energy from the reservoir. This heat energy is then passed to the heat transfer system at the surface.

Groundwater Engineering provides complete open loop geothermal solutions:

  • Scoping and feasibility studies
  • Pumping and re-injection tests
  • Well drilling and system installation
  • Environmental consenting and licensing
  • Monitoring of the performance of geothermal systems and advising on operational issues


Dewatering for Basement Construction
12 March 2016

Groundwater can be a significant problem when excavating for basement construction. This blog discusses the available techniques that can be used to dewater during basement construction.
