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
Rainwater harvesting is done to capture and store rainwater for future use. It helps in replenishing groundwater levels, reducing demand on local water sources, and mitigating the risk of water shortages during dry periods. It is a sustainable practice that promotes water conservation and reduces reliance on traditional water sources.
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.
In conclusion, rainwater harvesting is a sustainable practice that can help alleviate water scarcity issues and reduce reliance on traditional water sources. It is a cost-effective way to conserve water, improve water quality, and promote self-sufficiency in water supply. Implementing rainwater harvesting systems can have significant environmental and economic benefits for both individuals and communities.
Rainwater harvesting helps to conserve water, reduce demand on traditional water sources, decrease water bills, and can help reduce the risk of flooding and erosion in urban areas. Additionally, collected rainwater can be used for irrigation, toilet flushing, and other non-potable uses, thereby reducing dependency on treated water for such purposes.
Rainwater harvesting is important because it can help alleviate water scarcity issues by capturing and storing rainwater for later use. It helps to reduce reliance on traditional water sources like rivers and groundwater, which are often overexploited. Additionally, it can reduce urban flooding and erosion by slowing down the runoff of rainwater.
Rainwater harvesting is a sustainable practice that can help conserve water resources, reduce stormwater runoff, and alleviate pressure on traditional water supplies. It can contribute to water self-sufficiency, help mitigate flooding, and improve water quality by reducing pollutants in runoff. Overall, rainwater harvesting is a valuable strategy for promoting water conservation and resilience in the face of water scarcity and increasing urbanization.
Rainwater harvesting is important because it allows us to capture and store rainwater for later use, reducing the demand on traditional water sources such as rivers and underground aquifers. It is a sustainable way to conserve water, especially in areas prone to drought or water scarcity. Additionally, rainwater harvesting can help to reduce runoff and erosion, as well as decrease the risk of flooding in urban areas.
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.

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