As we all know water is essential for all of us.but now in the modern world we dont think about it and continuously waste it.only 1%water on the surface of the earth is in usable form.rain water is the purest form of water.rain water harvesting means means collecting  of rain water for after use.it can be stored in tanks or even in buckets.the water stored  can be used for various purposes like watering plants washing utensils etc.water is a precious resource.we should not waste it .it is our need thats why we should think for the future and we should save water.
