Water covers 70.9% ofthe Earths surface, and is vital for all known formsof life. On Earth, 96.5% of the planets water is foundin oceans, 1.7% in groundwater, 1.7% in glaciers andthe ice caps of Antarctica and Greenland, a smallfraction in other large water bodies, and 0.001% inthe air as vapor, clouds (formed of solid and liquidwater particles suspended in air), and precipitation. Only 2.5% of the Earths water isfreshwater, and 98.8% of that water is in ice andgroundwater. Less than 0.3% of all freshwater is inrivers, lakes, and the atmosphere, and an even smalleramount of the Earths freshwater (0.003%) is containedwithin biological bodies and manufactured products.
Water isa chemical substance withthe chemical formula H2O.A water molecule containsone oxygen andtwo hydrogen atomsconnectedby covalent bonds. Water isa liquid at ambientconditions, but it often co-exists on Earth withits solid state, ice, andgaseous state (watervapor or steam).
Water is lifeVirtually everything we do or use each day involveswater. Yet, we do not give it the importance that isdue to it. India will soon be a water-stressed countryand we all need to work towards our water security.Simple actions can be adopted to reduce the wastageof water and use it wisely.
India is gifted with a rich and vast diversity ofnatural resources, water being one of them.Its development and management plays a vitalrole in agriculture production. Integratedwater management is vital for povertyreduction, environmental sustenance andsustainable economic development. NationalWater Policy (2002) envisages that the waterresources of the country should be developedand managed in an integrated manner.
Water resources are divisible into two distinct categories :1. The surface-water resources.2. The under ground-waterresources
Water pollution occurs when a body of water is adversely affected due to the addition of large amounts of materials to the water. The sources of water pollution are categorized as being a point source or a non-source point of pollution. Point sources of pollution occur when the polluting substance is emitted directly into the waterway. A pipe spewing toxic chemicals directly into a river is an example. A non-point source occurs when there is runoff of pollutants into a waterway, for instance when fertilizer from a field is carried into a stream by surface runoff.

Water conservation refers to reducing the usage of water and recycling of waste water for different purposes such as cleaning , manufacturing ,and agricultural irrigation
Reduce personal water costs Minimize the need for local governments to fund expensive reservoir, water treatment plant and pipeline projects Help maintain sufficient water in streams, rivers and lakes for fishing, boating, swimming, protection of aquatic life and downstream users.
Increase the crop water use efficiency Improve irrigation application efficiency Increase capture and utilization of precipitation Increase irrigation water diversion and delivery efficiencies Reduce water use through adoption of conservation measures and new technologies for water management
