Rain water harvesting refers to the act of ensuring that the rain water gets perculated into the soil rather than flow off.This may be implemented in several ways.The rain water from rooftops get collected and made to flow into a well. Tamil Nadu in India is the first state to implement this scheme in a large scale.
There has been a considerable rise in the water table.
catching rain
Any rainwater harvesting system has three components: Catchment, Conveyance, and Storage. There are two classes of rainwater harvesting systems:
The six basic components of a Rain Water Harvesting system include:
Rain water harvesting in rural areas :
Roof water harvesting rural schools
Rainwater Harvesting (RWH) from roofs is a simple low cost technique that has been practiced for hundreds of years in the desert areas of India. For over two decades, the Barefoot College has provided drinking water in remote rural schools in 15 states for about 32 million people by collecting rainwater from rooftops of the schools and storing it in underground tanks.
In remote villages where access to drinking water is a major problem, RWH structures serves two purposes:
The Construction of a RWH system
Before construction of a RWH system, it is necessary to gather information about schools that face shortage of water, existing water resources in the village, roof top area where RWH could be taken up and types of soil in the village.
Rooftop Rain Water Harvesting is the technique through which rain water is captured from the roof catchments and stored in reservoirs. Harvested rain water can be stored in sub-surface ground water reservoir by adopting artificial recharge techniques to meet the household needs through storage in tanks. The Main Objective of rooftop rain water harvesting is to make water available for future use. Capturing and storing rain water for use is particularly important in dryland, hilly, urban and coastal areas. In alluvial areas energy saving for 1m. rise in ground water level is around 0.40 kilo watt per hour.
It's used for several purposes such as..... 1. For drinking after filtered. 2. For irrigation. 3. For house hold purposes
collection of water, its storage for later use is called water harvesting
To prevent accumulation of water during flood. Moreover we can use this water for various household activities which saves a great amount of groundwater.
Collecting the rainwater that comes off your roof.
Harvesting rain water is to ensure a steady supply of water for domestic and industrial use through out the year and during any season.
By rain water harvesting and irrigation
Rain water is free, so if you use rain water you are not depleting the water supply in the dams. This means that fewer resources will be required to build more dams or water reserves. Rainwater tanks can be plumbed into your toilet cisterns and even as cold water for your clothes washing machine. Some places give rebates to subsidize tank installation. Check with your local authority and Water Board.For collecting water.The survival of humans and animals.Using the collected water.
It is a very useful process during rainy season and during the scarcity of water.by doing this process we can safe water for domestic purpose,drinking purpose and for future needs.it is a very simple and affordable process.with the decreasing availability of water, rain water harvesting is the best option .
Rain water harvesting should be done at the drought occurring areas.
We can make good use of rain water by storing rain water and by rain harvesting.
We can make good use of rain water by storing rain water and by rain harvesting.

Teach them how to compost their humanure; so they can conserve their drinking water and prevent contamination. rain harvesting can be done also.
