Answer:
Rainwater harvesting (RWH) is a simple low-cost technique that requires minimum specific expertise or knowledge and offers many benefits. For drinking water purposes in rural areas, the most common technique is small-scale rooftop rainwater harvesting: rainwater is collected on the roof and transported with gutters to a storage reservoir, where it provides water at the point of consumption (for rainwater harvesting for agricultural use see also bunds, field trenches, planting pits, micro-basins, retention basins, sand dams, conjunctive use, gully plug, controlled drainage or fog drip). Collected rainwater can supplement other water sources when they become scarce or are of low quality like brackish groundwater or polluted surface water in the rainy season. It also provides a good alternative and replacement in times of drought or when the water table drops and wells go dry. The technology is flexible and adaptable to a very wide variety of conditions. It is used in the richest and the poorest societies, as well as in the wettest and the driest regions on our planet (HATUM & WORM 2006) (see also precipitation harvesting for a general overview on RWH).
