What is the importance of water harvesting?
The importance of rainwater harvesting lies in the fact that it can be stored for future use. Just as it can be used directly so also the stored water can be utilized to revitalize the ground level water and improve its quality. This also helps to raise the level of ground water which then can be easily accessible.
What is water harvesting short note?
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. Water harvesting means to understand the value of rain, and to make optimum use of the rainwater at the place where it falls.

What is the importance of rainwater harvesting conclusion?
Rainwater harvesting is an eco-friendly technique to save water. It also increases level of ground water. Effective use of this method helps us to Save our earth.
What is water harvesting answer?
Rainwater harvesting (RWH) is the collection and storage of rain, rather than allowing it to run off. Rainwater is collected from a roof-like surface and redirected to a tank, cistern, deep pit (well, shaft, or borehole), aquifer, or a reservoir with percolation, so that it seeps down and restores the ground water.

What are benefits of water harvesting 10?
It provides drinking water. It provides irrigation water. It is responsible for the increase in groundwater level. It reduces storm water discharge, urban flood and overloading of sewage treatment plants.
How does rainwater harvesting help the environment?
As rainwater harvesting slows the runoff water and makes it sink under the soil, it makes the soil pleasantly rich with nutrients and keeps it healthy. This is extremely necessary since the demand for food is increasing every minute. A total of 200,000,000 litres of water is used per second to grow food for our planet.
