Artificial Recharge of Ground Water

Abstract

Artificial Recharge Of Ground Water scarcity is one of the major issues that has yet to be fully resolved, and water table depletion has become a major problem worldwide. Water demands are increasing as our population grows. Excessive demand has placed a strain on our water resources.

The recharge rate is much lower than the rate at which the water is pumped out. This over exploitation has many environmental effects, including water quality degradation, reduced quantities of water in wells and springs, and land subsidence, to name a few.

The groundwater problem in India is more prominent in areas with a high economy in agriculture, although it is also high in urban areas. In the last 5 years, over exploitation in National Capital Delhi has reduced the depth of the water table by a considerable amount.  In addition, in support of this, we have also narrated two-state case studies (Site–1 and Site–2) to explain groundwater conservation through artificial recharge.

According to Seckler et al., the 1998 International Water Management Institute (IWMI) study estimated that about one-fourth of the world’s population (1.4 billion people) will experience water scarcity in the first quarter of the next century. One of the factors that has arisen from water scarcity is the depletion of the natural resource that is groundwater. But nowadays it leads to its depletion due to overuse or overdraft.

Conclusion

The best and simplest plus cost-effective technique is direct groundwater recharge, which also includes the ditch & furrow method, percolation tanks and recharge of dug wells or hand pumps. Water scarcity has become the major problem, especially in most arid regions of the world, which ultimately affect food safety, natural ecosystems, plant and human health.
