CASE STUDY




IMPORTANCE
With two thirds of the earth's surface covered by water and the human body consisting of 75 percent of it, it is evidently clear that water is one of the prime elements responsible for life on earth.  Contrary to the past, our recent developed technological society has become indifferent to this miracle of life. Our natural heritage (rivers, seas and oceans) has been exploited, mistreated and contaminated.
Getting water appears to be easy and cheap, but if its importance is not understood now, it could become costlier. To tackle the problem in a meaningful way methods of rain water harvesting should be used as a basic facility .Wasteful use of water should be checked. Only 0.5 per cent—nearly half of this in Maharashtra—is under drip irrigation and 0. 7 %. There is large-scale pollution of water as a result of industrialisation and urbanisation. This trend has got to be checked.Although one-eighth of India is declared as food .The economy in water-use in this sector will have two benefits. Firstly, the saved water may be used to meet the demand in other sectors. Secondly, the affluents thrown in the water bodies will be less.
 Rain water harvesting is one of the most effective methods of water management and water conservation. It is the term used to indicate the collection and storage of rain water used for human, animals and plant needs.The harvesting of rainwater simply involves the collection of water from surfaces on which rain falls and subsequently storing this water for later use. Normally water is collected from the roofs of buildings and stored in rainwater tanks.
 
The benefits of rainwater harvesting are numerous; the following are some of them
1.        The gathered rainwater can be used for agricultural purposes. The environment may be helped to get rid of the tendency to drought.
2.      The requirement of water for feeding the live-stocks can be met.
3.     Wastage of water flowing through drain, gutter, or any water-cause can be stopped and damage to water-course of any type may be stopped.
4.      Water-logging on roads and thoroughfares can be checked and localities can be saved from being inundated.
5.     The quantity of water can be raised and soil erosion can be checked.
Roof top rain water harvesting can be a very effective tool to fight the problem of water shortage particularly in urban areas. Roof top rain water harvesting depends upon the amount of rainfall and the roof top area.
If we see example of drought-hit Latur in Maharashtra, the people did not conserve water and faced the consequence. So it is everybody's responsibility to ensure that there is no wastage of water.
People were receiving drinking water once in 15 days. Some people died and many left latur. The Sugar Factory has a reservation of about 0.5 Million Cubic Meters of water that is a whopping 5000 lakh litres of water in the driest months.
As India faces one of its biggest droughts since Independence, such stories and surrounding conflicts are the new normal. Especially for Marathwada, a region which received 42% deficit rainfall in 2014 and 40% in 2015. Before settling at 40% deficit in 2015, Marathwada showed the highest deficit in the country at 52% for a long time during monsoon 2015.
The Water Train arrived in Latur on 12th April, carrying 5 lakh litres of water for the more than 400,000 people of Latur City. This situation could have been prevented if people would have installed rainwater harvesting system.
