Expert instructor

Mark Ragel, owner of Water Harvesting International. Following in his father’s footsteps, Mark started in the pool and spa business. In 2008, Mark traveled to Africa where he used his expertise in the pool industry to install lifesaving rainwater-collection cisterns. The experience changed Mark’s life and business focus, and he went on to found Water Harvesting International. Water Harvesting International installs above- and below-ground cisterns of all types including FDA-approved drinking water storage systems. They also specialize in conversion of existing swimming pools into water storage cisterns. Mark was praised by students in a previous course as a “patient yet energetic and engaging teacher”.
