Rainwater Harvesting An Emerging Technology For Water Management In Hilly Region

Abstract

Rainwater plays a very vital role in the development of any country. With the sufficient rainwater, the production of crops increases with which the farmers are benefitted. But the rainwater gets wasted in hilly region due to insufficient storage and very high runoff.
Rainwater harvesting is an important technique for making use of rain water. According to the survey, the major problem of the farmer was how to use rainwater. Thus, because of insufficient storage and high runoff, the rainwater which is not harvested is a wastage of water and this waste water drains through surface flow. The wastage of rainwater must be harvested, and this runoff water must be taken to reservoirs made for storage water and further be passed to the pipelines laid for domestic demand and other utilization keeping in mind, to minimize the delivery losses. This kind of rainwater harvesting could lead to an increment in the production of underground vegetables. This harvested water could also be utilized for the domestic use and could be consumed by animals too. In the hilly regions the roofs of the houses are provided with a slope followed by a roof water harvesting system. This roof water harvesting system is attached to a drainage pipeline. The disposal of this drainage pipe line is in the reservoir tank which was made for the storage of rainwater. This paper comprises of the various methods to be undertaken for the harvesting of Rainwater
