In the state of Tamil Nadu, the Supreme Court issued some guidelines for drilling a borewell. At least 15 days before digging up a borewell, you need to get permission from the concerned urban or rural local bodies and with the Department of Ground Water or Public Health. It is necessary to follow the general rules given by the collector while drilling the borewell. Try to abide by the legal framework and finish the legal formalities before signing the contract with the borewell contractor.
