Abstract
ABSTRACT: The water scarcity is one of the major issue which is yet to not solve completely and
depletion of the water table has become a major problem across the world. Demands for water
increases as our population grow. Though 75% of the earth is covered by water, only a small
percentage of it is fit for human use. The excessive demand has put a strain on our water resources. In
many areas groundwater, which makes about 20% of our fresh water supply, is being used extensively
for a variety of human, agriculture and industrial use. The recharge rate is much less than the rate at
which the water is being pumped out. This overexploitation has a lot of environmental effects which
include degradation of water quality, reduced quantity of water in wells and springs, and land
subsidence to name a few. In India the groundwater problem is more prominent in areas with a high
agriculture economy, though it is high in urban areas also. The overexploitation in the National
Capital Delhi has reduced the water table depth by a considerable amount in the last 5 years. Artificial
methods to recharge the groundwater can be used to supplement our water resources. Different
methods, based on the climatic and geographical conditions, can be used. In dry areas, for example,
watersheds can and are being used to manage water resources. In this paper we have reviewed and
summarized different studies to suggest a variety of methods to recharge groundwater. Artificial
recharging of aquifer is one of the option, in order to improve groundwater crises which is sustainable
in the long term. Some of the techniques are already been used and many could also be easily put in
use by the villagers with local resources availability in terms of manpower and materials
(www.megphed.gov.in). We have studied the groundwater recharge process in relation to the climatic
and geographical conditions and make a list of pros and cons for different methods with secondary
date available in literature. Moreover, in support of this we have also narrate the case studies of two
states (Site–1 and Site–2) to explain the conservation of groundwater by artificial recharge. The
overall efficiency of the methods used to artificially recharge groundwater have sufficiently
explained.
