Water is an integral part of land/soil productivity. Its misuse can cause both degradation and erosion of soils. Management of water resource is considered to necessary for well being of human life as well as crop yields. There is a gap between the seasonal availability of water and its equitable supply throughout the year. Accordingly the storage of water and passage through soils is very important. It is well known that about 70% area in this country is subject to varying degree of water stress

How water is purified in water treatment plants Pre-treatment 1. Pumping and containment – The majority of water must be pumped from its source or directed into pipes or holding tanks. To avoid adding contaminants to the water‚ this physical infrastructure must be made from appropriate materials and constructed so that accidental contamination does not occur. 2. Screening (see also screen filter) – The first step in purifying surface water is to remove large debris such as sticks‚ leaves

WATER RESOURCES The sources of water that are useful to human life are called water resources. Uses of water include agricultural‚ industrial‚ household and recreational activities. The majority of human uses require fresh water. 97 percent of the water on the Earth is salt water and only 3 percent is fresh water; slightly over two thirds of this is frozen in glaciers and polar ice caps. The remaining unfrozen fresh water is found mainly as groundwater‚ with only a small fraction present above
