to define the human right to water came from law professor Stephen McCaffrey of the University of the Pacific in 1992 and Dr. Peter Gleick in 1999. McCaffrey stated that "Such a right could be envisaged as part and parcel of the right to food or sustenance, the right to health, or most fundamentally, the right to life. Gleick added: "that access to a basic water requirement is a fundamental human right implicitly and explicitly supported by international law, declarations, and State practice." The UN Committee for Economic, Social and Cultural Rights (CESCR) overseeing ICESCR compliance came to similar conclusions as these scholars with General Comment 15 in 2002. It found that a right to water was implicitly part of the right to an adequate standard of living and related to the right to the highest attainable standard of health and the rights to adequate housing and adequate food. It defines that "The human right to water entitles everyone to sufficient, safe, acceptable, physically accessible and affordable water for personal and domestic uses. An adequate amount of safe water is necessary to prevent death from dehydration, to reduce the risk of water-related disease and to provide for consumption, cooking, personal and domestic hygienic requirements." Several countries agreed and formally acknowledged the right to water to be part of their treaty obligations under the ICESCR (e.g., Germany; United Kingdom; Netherlands) after publication of General Comment 15. A further step was taken in 2005 by the former UN Sub-Commission on the Promotion and Protection of Human Rights which issued guidelines to assist governments to achieve and respect the human right to water and sanitation. These guidelines led the UN Human Rights Council to assign Catarina de Albuquerque as an independent expert on the issue of human rights obligations related to access to safe drinking water and sanitation in 2008. She wrote a detailed report in 2009 that outlined human rights obligations to sanitation, and the CESCR responded by stating that sanitation should be recognized by all states. Following intense negotiations, 122 countries formally acknowledged "the Human Right to Water and Sanitation" in General Assembly Resolution 64/292 on 28 July 2010. It recognized the right of every human being to have access to sufficient water for personal and domestic uses (between 50 and 100 liters of water per person per day), which must be safe, acceptable and affordable (water costs should not exceed
