In India, culture lives along the rivers, because water is life. Nature has given the human being everything in abundance, but following the development of mans needs all the natural resources becoming dearer and dearer. Water is one of them. Man started building huge dams after spending crores and crores of rupees to meet their ever growing needs for drinking water, agriculture, industrial, construction purposes etc. But following the changes in climate, erratic rainfall or drought like situation, water became dearer and valuable commodity.
In ancient times water was used, stored and means of easy availability was done in a very very practical and less expensive manner. One of them was by building very small wall (about 10 to 20 ft wall) along the path of river at regular interval (every few kilometer), to meet the requirement of every village and small towns along the rivers. In this manner the water is stored along the path of river and as water overflows every small dams and flows into the next one. As a result the ground water level was always maintained and water is available almost throughout the year. Most of rained water gets collected in the small dams all along
the river path. Such small dams do not cost much. If the costs of all such small dams all along the river are put together, it works out to much more less than any one big dam and can be completed in a very short time (within 2 years or less at local level).
The water stored in such small dams is around 20 – 200 million liters which is enough to meet the requirement of all villages nearby such dams. The path of river before it reaches sea is around 1500 to 3000 kilometers. If dams of 10 to 15 ft. height are built at every 3 to10 km. distance depending upon location and river bed size there could be 300 to 600 such small dams along the path of one river, and water stored is around 50-100 billion liters. Since water remains in the dams almost through out the year, the water level of wells are also maintained and available round the year which is available in addition. Every drop of water is useful before it is drained out to sea. All efforts are must to conserve the water, because it is life.
