Storage of Harvested Rainwater

The collection and storage of roof top rainwater in a large pot / vessel kept on the surface or below the surface for later use is an equally important technique of Rainwater Harvesting. It is mostly used in areas where rainwater recharge is not possible and ample amount of rainfall is available. The water thus collected can meet immediate domestic needs. Tanks made of Zinc-Aluminium, iron sheets, cement, or bricks, ferrocement, PVC, or even hard rocks can be used for storing the water. In such tanks water can be stored for a long period. The water gets deteriorated only if it comes in contact with the sunlight and dust. In hard core, hilly villages this water is used for drinking after due chlorination.
