Earth’s water is (almost) everywhere: above the Earth in the air and clouds, on the surface of the Earth in rivers, oceans, ice, plants, in living organisms, and inside the Earth in the top few miles of the ground.

This is the fifth country in the world which has largest freshwater reserve. Poyang Lake which is situated in Jiangxi Province is the largest freshwater lake in China….Shakeel Anwar.

Fresh water is found in glaciers, lakes, reservoirs, ponds, rivers, streams, wetlands and even groundwater. These freshwater habitats are less than 1% of the world’s total surface area yet house 10% of all known animals and up to 40% of all known fish species.

While our planet as a whole may never run out of water, it’s important to remember that clean freshwater is not always available where and when humans need it. In fact, half of the world’s freshwater can be found in only six countries. More than a billion people live without enough safe, clean water.

3% of the earth’s water is fresh. 2.5% of the earth’s fresh water is unavailable: locked up in glaciers, polar ice caps, atmosphere, and soil; highly polluted; or lies too far under the earth’s surface to be extracted at an affordable cost. 0.5% of the earth’s water is available fresh water.

These are the different types of water sources around the globe and how they each play a role in what comes out of your home’s sink.

• Surface Water Resources.
• Groundwater Resources.
• Stormwater Resources.
• Wastewater Resources.
• Saltwater Resources.
• Ice Cap Water Resources.

Over 68 percent of the fresh water on the Earth is found in icecaps and glaciers, and just over 30 percent is found in ground water. Only about 0.3 percent of our fresh water is found in the surface water of lakes, rivers and swamps.

1. Eritrea: 80.7% lack basic water services. The population of Eritrea in East Africa has the least access to clean water close to home. Lack of adequate household sanitation means open water sources are often contaminated by human and animal waste.
