Water Supply and Proper Sanitation Process

When a water supply plan can not fulfill customer needs or desires, it is operated according to standards, or simply called unsatisfied supply; such dissatisfied supply will complain the service. In 2002, the United Nations Economic and Social and Cultural Rights Committee (Economic and Social and Cultural Rights Committee) adopted general opinion No. 15 on water rights (Article 11 and 12 of the "International Economic and Social Cultural Rights Convention" ) The economic, social and cultural rights committee defines the right to water as everyone has the right to obtain sufficient, acceptable, achievable, affordable water for families and individuals I will.

Clean water supply - the supply not contaminated with feces, especially due to lack of hygiene - is the most important determinant of public health. After a massive disaster (earthquake, flood, war etc), destruction of water and sanitation equipment poses a direct threat to the serious spread of waterborne diseases, some of which can be life-threatening. After appropriate processing, the water supply system can obtain water from various places including groundwater (aquifer), surface water (lakes and rivers), seawater desalination from sea water. In most cases, the water treatment process includes purification, chlorination and sometimes fluorination. The treated water flows by gravity or is pumped up to the reservoir. It can be raised like a water tower or the ground (see Non-income water for indicators of distribution efficiency of drinking water).

It is particularly difficult to provide water and sanitation services to the poor and the poorest people. Many people in these areas can not use safe drinking water and appropriate sanitation facilities. Hygiene management and wastewater treatment are often inadequate or lacking even if adequate water is being supplied. Pit toilets and septic tanks are a common method of treating human excrement, but even if the capacity is limited, it is not always sufficient to handle the amount of waste generated by many living together There is none. Spilling toilets and septic tanks contaminate surface water and cause serious health risks
