Some of the uses for water-harvesting systems include harvesting and storing the rainwater whenever it rains. This harvested water has many benefits, ranging from providing supply in the future to saving on the annual water budget.
Rain is a universal source of free water. Although the two-thirds of the whole earth is covered with water, most of the water is not suitable for drinking or other home use. Precipitation or rain is one of the sources of clean water. Many parts of the earth experience periodical rain seasons followed by dry seasons. Rain harvesting has therefore become an important activity of acquiring fresh water suitable for all home purposes. The water-harvesting system is composed of collecting gutters that are connected and linked with pipe systems that drain the rainwater into storage tanks.
