     Clean water is one of the resources of good quality water-based and commonly used by humans for consumption or in performing their daily activities including the sanitation.
For consumption of drinking water by health department, the terms of the drinking water is tasteless, odorless, colorless, and does not contain heavy metals. Although water from natural sources can be drunk by humans, there is a risk that the water has been contaminated by bacteria (eg, Escherichia coli) or harmful substances. Although the bacteria can be killed by cooking water up to 100 ° C, many harmful substances, especially metals, can not be eliminated in this way.

 
River water average of more than 40,000 cubic kilometers of fresh water is obtained from rivers in the world. Availability of this (equivalent to more than 7,000 cubic meters per person) at first glance does look enough to guarantee a sufficient supply for all residents, but the fact that water is often available in places that are not appropriate. For example, clean water in the Amazon basin enough even though its availability, its location makes this water source is not economically viable to export water to places that require water in a very large number and stable.

 

Rainfall
   In the utilization of rain as a source of clean water, individual individual / group / government usually build dams and water reservoirs are expensive and bulky to store water in the winter months when dry and to reduce damage due to floods.

Abuse and forms Water pollution

Sources of clean water is usually impaired due to the use and abuse of water resources such as:

1, Agriculture Wastage of water due to the absence of good water distribution on irrigated land with irrigation (for savings in the short term) can result in puddles and salting which ultimately can lead to loss of water and soil productivity

2, Industrial  Although industry uses much less water than irrigated agriculture, but the use of water by industry may carry a more severe impact is viewed from two aspects. First, the use of water in industry are often not regulated in the policies of water resources nationwide, then tend to be excessive (over limit). Secondly, the disposal of industrial waste is not treated properly can lead to contamination of surface or underground water, making it too dangerous for consumption. Industrial waste water is often discharged directly into rivers and canals, contaminating it, and ultimately pollute the marine environment, rivers, or sometimes just exiles allowed to seep into the groundwater sources without undergoing any treatment. Damage caused by this exhaust has passed the proportion of contents, There are many modern chemicals are so powerful that little contamination alone is enough to make the water in very large volumes can not be used for drinking without any special processing.

Exploitation of water resources by household mass.

 In developing countries: in some places in the state of Tamil Nadu in southern India which do not have laws governing the installation of suction tube wells or restrict suction of ground water, the ground water level dropped 24 to 30 meters during the 1970s as a result of not contloling digging artesian wells for pumping or irrigation. At a water conference in 2006 the representative of a country which is a dry report that 240,000 private wells were drilled without regard to the capacity of water supply network resulted in drought and increased salinity.
     In developed countries such as the USA 1/5 of all irrigated land in the United States depends only on the network of water supply (Aquifer) Agallala that almost never receive supply naturally. Over the past four decades starting from 2006, the network systems that depend on this resource extends from 2 million to 8 million hectares, and approximately 500 cubic kilometers of water has been sucked. The source network is now already half dried under a number of states. Water sources are also experiencing deterioration of quality, in addition to pollution from industrial waste and untreated urban sewage well, such as heavy fouling of the remnants of agricultural land. For example, in the western part of the United States, the Colorado river bottom is now so high salt content as a result of the impact of the reverse flow of irrigation so that in Mexico has not useful anymore, and now the United States was forced to build a major project to purify salt water in Yuma, Arizona, to improve the quality of the river. The situation in urban areas is much worse than in the source area where households are underserved forced to maintain the toilet by way of improvised because of the scarcity of water and septic tank exploded because the service dewatering unreliable, or simply by using other ways that equally complete and unhealthy. It is not just a problem for the users themselves, still too often dangerous to others and is a threat to the environment because their waste off without processing or filtering waste.
