Groundwater drilling services is groundwater tube-well and pumping test.Well development method is by air-lift and surging using compressor until the water become clear and sand free. At the end of all operations, sodium hypochlorite will be used to disinfect the water in the tube-well. An initial stage of Aquifer Pumping Test is conducted by air lifting every 25 to 50 meters interval of the well depth. This is done to determine the yield of the well capacity and the pumping level.The discharge water is channeled to flow meter for calibrating the performance and aquifer properties. A final stage standard pumping test is conducted after installing with submersible pump
