Water supply system, infrastructure for the collection, transmission, treatment, storage, and distribution of water for homes, commercial establishments, industry, and irrigation, as well as for such public needs as firefighting and street flushing.

The UN General Assembly has declared access to clean water and sanitation a "human right" in a resolution that more than 40 countries including the United States and Canada didn't support.

One billion people around the world don't have access to clean, safe water. Developed countries have essentially eradicated diseases such as cholera, typhoid and malaria, but in developing nations, these and other waterborne illnesses kill 5 million people each year -- 6,000 children every day.

One of the most pervasive problems afflicting people throughout the world is inadequate access to clean water and sanitation. Problems with water are expected to grow worse in the coming decades, with water scarcity occurring globally, even in regions currently considered water-rich.

Water's crucial role in accomplishing the continent's development goals is widely recognized. Africa faces endemic poverty, food insecurity and pervasive underdevelopment, with almost all countries lacking the human, economic and institutional capacities to effectively develop and manage their water resources sustainably. Thus, a large number of countries on the continent still face huge challenges in attempting to achieve the United Nations water-related Millennium Development Goals (MDGs) .

China and India alone recorded almost half of world’s progress, with increases of 457 million and 522 million, respectively since 1990. This is not surprising, however, since the inhabitants of these two countries represent 46% of the developing world’s population. Of note are the impressive gains in Eastern Asia, which added 23 percentage points, and the small decline in coverage in the Caucasus and Central Asia and in Oceania.

The main finding of this work is the identification and description of all the major shared surface water basins and aquifer systems in Western Asia.

Warka Water is an alternative water source to rural population that faces challenges in accessing drinkable water. It is first and foremost an architecture project. WW should not be considered as the solution to all water problems in developing countries but rather as a tool that can provide clean water in selected areas, particularly in mountainous regions where conventional pipelines will never reach and where water is not available from wells. These remote communities, often with limited financial means, struggle to find reliable supplies of clean water for the people, the animals and for agriculture.
