RAIN WATER HARVESTING

By Team - FRAM CRAFT

Rain water harvesting (RWH) is a simple method by which rainfall is collected for future usage. The collected rainwater may be stored, utilized in different ways or depleting groundwater levels and fluctuating climate conditions, RWH can go a long way to help mitigate these effects. Capturing the rain water can help recharge local aquifiers, reduce urban flooding and most importantly ensure water availability in water scarce zones through the term seems to have picked up greater visibility in the last few years, it was, and is even today “traditional practices “followed in rural India. Some ancient rain water harvesting methods followed in India include "Madakas", "Ahar pynes", "Surangas", "Taankas" and many more.These water conservation methods can be easily practiced in individual homes, apartments, parks, offices and temples too, across the world. Farmers have recharged their day bore wells, created water banks in drought areas, greened their farms, increased sustainability of their water resources and even created a river.


Components of a Rain Water Harvesting System:

A Rain water harvesting system comprises components of various stages_transporting rain water through pipes or drains, filtration, and storage in tanks for reuse. The common components of a rain water harvesting system involved in these stage are illustrated here.


1.Catchment: The catchment of a water harvesting system is the surface which directly receives the rainfall and provides water to the system. It can be a paved area like terrace or courtyard of a building or an unpaved area like a lawn or open ground. A roof made of reinforced cement concrete (rcc), galvanized iron(GI) corrugated sheets can also be used for water harvesting.



2.Coarse mesh: At the roof of prevent the passage of debris

3.Gutters: Channels all-round the edge of a sloping roof to collect and transport rain water to the storage tank. Gutters can be semicircular or rectangular.

Gutters need to be supported so they do not fall off when loaded with water. The way in which gutter are fixed depends on the construction of the house.

4.Conduits: Conduits are pipelines or drains that carry rain water from the catchment or rooftop area to the harvesting system conduits can be of any material like polyvinylchloride(pvc)or galvanized iron(GI), material that are commonly available.

The best part about rain water harvesting is that it saves a lot of time as you do not have to fetch time in order to store water you can simply filter out the impurities from the water and it can be used for purposes like gardening, crop irrigation, watering livestock, laundry. Also it should be noted that rainwater is not ideal for drinking and bathing purpose but can be used for all mentioned purposes. As this method is really easy and does not require any advanced equipment or hi-tech water purifiers, it is also an extremely budget friendly option.
