Romulus, you have raised a very valid question. But you might have heard that the wastage of water is creating water logging conditions in most parts of the world, resulting in reduction in actual irrigated area in the project and reduction in yield per hectare.

In the areas for which you have narrated above, where water table is going down, suitable steps be taken to recharge ground water. Leaching of of salts may be done by providing proper drainage system and flushing irrigated lands by suitable quantity of water. But based on your observations, proper design and construction of water storage reservoirs and conveyance system like canals, minors and field channels( water courses) should not be objected.
