41 million cubic kilometers, or, about 3% of the earths water, is fresh water. According to http://www.space.com/scienceastronomy/050907_ceres_planet.html The total volume of water on Earth is about 1.4 billion cubic kilometers, around 41 million of which is fresh water.

i heard 2%

I posted this question before trying to find an answer. Then found this info: About 1.6% of the earth is fresh water. This means there would be about 40 million gallons of fresh water for each person. Problem is, I don't know where I got that, without back tracking all over again. How right does it sound?

Only 2.5% of water on the Earth is fresh water, and over two thirds of this is frozen in glaciers and polar ice caps. Water demand already exceeds supply in many parts of the world, and many more areas are expected to experience this imbalance in the near future. The framework for allocating water resources to water users (where such a framework exists) is known as water rights. Uses of fresh water can be categorized as consumptive and non-consumptive (sometimes called "renewable"). A use of water is consumptive if that water is not immediately available for another use. Losses to sub-surface seepage and evaporation are considered consumptive, as is water incorporated into a product (such as farm produce). Water that can be treated and returned as surface water, such as sewage, is generally considered non-consumptive if that water can be put to additional use. http://en.wikipedia.org/wiki/Water_resources

Although about three-fourth of earth is water, the estimated volume of freshwater our rivers, groundwater, snow and ice, is about 2.5% only, the rest being the sea / salt water. Most of the freshwater are either in the form of ice and permanent snow cover in Antarctic/Artic regions (about 69%) or is stored underground in the form of deep underground basins/aquifers, soil moistures etc (30%). Total usable freshwater supply to ecosystem and humans from river system, lakes, wetlands, soil moisture and shallow groundwater is less than 1% of all freshwater and only 0.01% of all the WATER ON EARTH. As per WHO estimates only 0.007% of all water on earth is readily available for human world consumption. This indicates that Freshwater on earth is finite and also unevenly distributed.

It's not really as important as you think. Only 2% of the water supply is utilised but it is something like 80% recycled. Meaning freshwater is used and reused in a loop.
