DRILLING AND INSTALLATION

Under normal circumstances, the drilling process for a village well generally lasts only one to three days. In more difficult areas, the process can take up to a week to complete. WHI has the capability of drilling through both rock and soft geological formations using either a down-the-hole hammer (DTH) or mud drilling methods. The completed well is cased with a 5″ PVC casing, and an India Mark II hand pump is installed. The average depth of wells drilled by WHI is approximately 50 meters.
