Geothermal

 

Since 1996, Rockwater has been at the forefront of geothermal energy projects in Western Australia. Rockwater has developed projects in regions such as the Perth Basin, where groundwater with temperatures of up to 55°C can be obtained from bores 500 to 1,200 m deep.

 

Perth is particularly well located for direct-use geothermal systems, with nine deep bores having been drilled for major direct-use projects (mostly swimming pool heating and space heating). Several other projects are in the planning and development phases.

 

Rockwater is the industry-acknowledged leading Hot Sedimentary Aquifer geothermal consultant in WA, having completed 70% of the direct-use geothermal projects in the Perth area. Rockwater obtained a special commendation in the 2002 Western Australian Water Industry Awards for conservation of water, and an Excellence Award from the Australian Institute of Refrigeration and Health (AIRAH) for the construction of a geothermal bore at Christ Church Grammar School.

 

In addition to deep-geothermal projects, Rockwater has developed shallow-aquifer systems whereby groundwater-supplied heat pumps are used primarily for space heating and the cooling of buildings.

 

Rockwater's skill set extends across a broad spectrum of geothermal project disciplines, and the Rockwater team were involved in the first commercial application of groundwater-supplied heat pump technology in Perth, at the Peppermint Grove Library. The project won a National Government Award in the "Energy Smart" category. Other geothermal projects undertaken by Rockwater include the construction of large-scale heat-rejection borefields into shallow aquifers for the cooling of large facilities, such as Edith Cowan University and the Pawsey supercomputer centre in Kensington.
