To increase the yield from groundwater wells in various rock types by hydrofracturing, tests of 12 wells were carried out as a part of sustainable groundwater development and artificial recharge project. Test wells are selected 5 wells in Jurassic granites, 2 wells in Cretaceous volcanics, 4 wells in Cretaceous sedimentary rocks and one well in Pre-Cambrian gneiss. The results show that specific capacity of II wells increased about 7% to 366%, while a well in Cretaceous sedimentary rock decreased about 43.4% owing to plugging of fault clay. Meanwhile, impact distances influenced due to hydrofracturing ranged from 5.4 m to 82.7 m from the test wells, actual drawdown data measured during the pumping test after hydrofracturing are more or less decreased and reveals balanced drawdown.
