Abstract
The efficiency of an irrigation engineer can be well judged from the canal water available at tail ends of the canals under his control. But often he finds it difficult to maintain authorised share of water at tails. In India position is particularly precarious during rice sowing period, which is monsoon season, i.e. rainy season in India at that time. It is the peak demand period for canal water. A deficit monsoon coupled with water theft makes it very difficult for authorised share to reach at tail ends. On the other hand, a good rain can cause tails to get flooded. It causes great loss to tail end users. This problem can be solved to some extent with the help of bore wells or dug wells, dug along the canal, more of them in the last one third of the length of the canal. These dug wells will act as rechargers of ground water during the period when there is excess of supply of water in the canals by diverting excess water to these bore wells, and will act as boosters during short supply by drawing this water through tube wells and mixing it with canal water. Though conjunctive use of tube wells along with canal water is being practised since long, this technique of first recharging aquifers with surplus canal water and then withdrawing this recharged ground water through tube wells during peak demand period, is particularly useful where ground water is otherwise brackish and is unfit for use.
