1.9.2. Feasibility of an Irrigation Project A proposed irrigation project is considered feasible only when the total estimated benefits of the project exceed its total estimated cost. However, from the farmer’s viewpoint, an irrigation project is feasible only if his annual returns (after completion of the project) exceed his annual costs by sufficient amount. The feasibility of an irrigation project is determined on the basis of preliminary estimates of area of land suitable for irrigation, water requirements, available water supplies, productivity of irrigated land, and required engineering works.
