A Large number of these projects are based on ground water utilization using modern methods and technology.It must be ensured while doing so that wells are spaced appropriately to ensure economic sustainibility.Modern irrigation techniques like drip irrigation and sprinkler irrigation are used to maximise water utilization and avoid erosion of aquifers.
