In general, water harvesting is the activity of direct collection of rainwater. The rainwater
collected can be stored for direct use or can be recharged into the groundwater Rain is the first
form of water that we know in the hydrological cycle, hence, is a primary source of water for us.
Rivers, lakes and groundwater are all secondary sources of water. In the process, it is forgotten
that rain, the ultimate source that feeds all these secondary sources and remain ignorant of its
value. Water harvesting is to understand the value of rain and to make optimum use of rain water
at the place where it falls.
In India, the small farmers depend on monsoon where rainfall is from June to October and much
of the precious water is soon lost as surface run off. While irrigation may be the most obvious
response to drought, it has proved costly and can only benefit a fortunate few. There is now
increasing interest in the low cost alternated generally referred to as rain water harvesting
(RWH). Rain water harvesting is the activity of direct collection of rain water which can be
stored for direct use or can be recharged into the groundwater. Water harvesting is the collection
of running water for productive purposes. It has become essential to save water in any and every
form. RWH is a very common and a very easy method of saving water. It has become the
responsibility of the human kind to save water.
Rainwater harvesting is one of the simplest and oldest methods of self-supply of water for
households, and residential and household-scale projects, usually financed by the user. However,
larger systems for schools, hospitals, and other facilities can run up costs only able to be financed
by owners, organizations, and governmental units.
