water source

water on earth is the result of the process of evaporation, infiltration and drainage ongoing. water from the soil surface will evaporate, changes to the cloud, and then fell into the rain or snow. partially absorbed and plants It is absorbed land into ground water, which at times can radiate to the surface layer of soil when the soil is soft, it becomes spring. according to the source / origin, water can be grouped into:
1. water sky: rain water, snow, ice.
2. surface water: river water, lake water, water reservoir, lake water, sea water.
3. ground water, which can be divided into:
a. water seepage or shallow ground water (water dig wells, hand pump water)
b. in ground water (water in the pump, in artesian well)
c. artesis water (strong jet of water to top)
d. spring (water source, the exit to the surface and can flow sendir)
