Water is life's essential ingredient.
Its importance for basic human survival and for food and energy production as well as for many other fundamental needs of the society gives this resource a significant role in socio-economic development. Water is, indeed, one of earth's most precious and most vulnerable to pollution. While health is also precious to all of us, it is also equally vulnerable to water borne diseases. There is a close link between health and water, not only through drinking water, but also through the adverse impacts of inadequate wastewater disposal and water shortages on public hygiene. Unsafe water is a breeding ground of disease and poverty.
