How do I claim subsidy for digging a farm pond or a well on my land?

Farm ponds, dug wells and water harvesting structures are supported under PMKSY watershed components, MGNREGA convergence, and various state water schemes, and the assistance is usually a fixed amount tied to the pond size and lining type rather than a flat percentage. The single most important rule is sequence: in almost every scheme you must get approval and a work order before you start digging. If you dig first and apply later, the structure is usually treated as already existing and rejected, because the department needs to verify the before and after condition, often with geo tagged photos at each stage. The process is: apply on your state portal or at the block office with your land record, Aadhaar and bank details, get site approval and the sanctioned dimension, dig to the approved size, get the before, during and completion stages verified, and receive the amount by DBT. For a lined pond the lining cost may be a separate component. Pond and well norms differ a lot between states and even between districts, so confirm the current rates, eligible size and the dig before or after approval rule with your block agriculture or watershed office before you start any earthwork.
