Hydro fracturing technique plays a significant role in increasing groundwater yield in the hard rock borewells. The technique involves injecting water under high pressure down the borewell to widen and clean the cracks and fissures in the rock formation. Hydro fracturing process in borewells was developed during the 1940�??s for enhancing the yield of oil and gas. Later this technique was adopted for water well development. The hydro fracturing process consists of pumping test before and after fracturing a well. The pumping test results are analyzed and correlated to understand the yield improvement before and after fracturing. An attempt was made to improve the groundwater yield from a borewell in a hard rock formation. The pre-pumping static water level was 4.25 m bmp and the safe yield was 5 lpm/16 m drawdown/8 hours of pumping per day. Hydro fracturing was carried out by a single packer system and two fracture zones lying at the depth of 15 to 45 m were treated. After fracturing treatment, the post-pumping test result revealed that the safe yield is 80 lpm/16 m drawdown/8 hours of pumping per day. The yield improvement indicated that hydro fracturing is a favorable outcome in the hard rock borewell.
