Locating Groundwater


In many developing countries, approximately half of newly-drilled water wells are dry. This is due to poor well siting methods, malfunctioning/outdated equipment and poorly-trained operators. With the cost of drilling today we cannot afford to rely on poor well siting methods. As an organization we experienced this problem in our early years of drilling in Kenya and only had a success rate of about 50%. This dilemma led us to search for better methods for locating where to drill new boreholes. Our search led us in two directions. The first direction was fracture trace analysis using Google Earth satellite photos to locate potential fractures that identify water-bearing sites. The second direction was acquisition of and training on equipment/technology that uses scientific methods for detecting groundwater. This technology allows us to see the approximate depth of an aquifer and the extent of an aquifer in real time on a laptop in the field. In addition, using this technology we are able to approximate the potential yield (how much water the well will produce every hour). This change in the way we approach a potential drilling location has increased our success rate in Kenya over the past three years to over 90%.
