Surface runoff is a term used for precipitation that falls on the surface of earth and is subsequently lost to essay rain water harvesting environment. If elaborate arrangements are made to collect surface runoff water by providing it a path into a pond or tank; gallons of water could be stored to be used for several activities.
If designed efficiently, essay rain water harvesting, a system to collect surface runoff water can collect huge quantities of runoff from roads, parks, and gardens etc enough to sustain a small community or even a city, essay rain water harvesting.

This traditional method of rainwater harvesting is followed in tropical belt of southern states of Karnataka and Kerala. These regions are rich in laterite soil with naturally occurring depressions with three high sides.
The three sides automatically function as the catchment area for collection of water in the depression. A small dam is constructed on the low lying fourth end of the depression to contain the runoff.
Surangas are traditional water harvesting system only used in Kasargod district of south Indian state of Kerala. The soil found in this region is hard laterite which is favorable for the construction of suranga essay rain water harvesting. Suranga is like a horizontal cave excavated in hilly terrain of the area, through which water oozes out and is thus collected in a pond.
Though, this method is locally being used since centuries, it is sadly now gradually being replaced by bore wells. Taankas are part of a traditional rainwater harvesting method practiced in the western state of Gujarat, essay rain water harvesting. Taankas are basically underground reservoirs with a capacity of storing thousands of liters of rainwater. Water stored in a taanka is sealed against sunlight and therefore remains fresh for years.
Rainwater harvesting provides an independent source of water supply during the scarcity of water. It becomes more valuable in context to the places where rain is scarce and uncertain. Also, in areas where fresh water is a costly commodity, preserving rain water is more economical option.
Rain water thus preserved can be used to meet several household requirements like — washing and cleaning, gardening etc. In case of unforeseen natural calamities like famine and droughts, rainwater harvesting might prove to be a blessing for the sufferers.
