Grant joined Rockwater, as our second employee, back in 1980. He is widely experienced in applied hydrogeology and geophysics, specialising in deep sedimentary aquifer investigations. Grant instigated Rockwater’s geothermal investigations in 1996 and currently leads our team of geothermal hydrogeologists. He has recently installed a shallow geothermal system for heating and cooling of his new house, which he hopes will be used as a model for others to follow.
