Water is one of the most important natural resource, it is the most basic need for all living beings as well as a very valuable national asset.
In India, Water availability per capita is on decline with most obvious reasons as increasing demand for water with increasing rate of population. Moreover the rivers are getting dried up, groundwater is depleting and canals are polluted. Other factors influencing /causing water shortage are felt as under:
1.Massive urbanization/ industrialization throughout the country
2.Increasing construction/ infrastructure development Activities
3.Depleting of natural resources due to changing climate conditions
4.Lack of implementation of effective water management systems
The increased demand has not been matched by efforts to conserve and better manage water supplies, meaning that the resource is being depleted faster than it can be replenished.
Considering the present circumstances ,India faces a bleak water future. India might face a severe water crisis within the next two decades, Unless water management practices are changed/ improved on priority basis.
India is blessed with adequate rainfall as a whole, yet there are large swathes of dry, drought prone area. In many other places the quality of groundwater is not good. In such places rainwater harvesting can provide lifeline water for survival and more.
Rain Water Harvesting as a method of utilizing rain water for domestic and agricultural use is already widely used throughout the world. It is a method which has been used since ancient times and is increasingly being accepted as a practical method of providing potable water in development projects throughout the world.
Rain water harvesting is regaining its importance as Government is exercising special efforts to promote the same supported by the efforts of NGOs like Rotary International who trying their best to create awareness in society to understand the significance of Rain water Harvesting (RWH).
It is understood from sources that Water Resource Ministry of India has adopted Target/Result oriented approach to deal with this alarming situation.
But more important is “Each one of us to learn as how to save even a drop of water”
