The ever increasing demand for clean water has prompted the world to consider water scarcity in a serious way. Some regions in the world are already at the brink of war over the ownership of major water resources, and it is feared that the situations may become worse. The marginalised people living in the impoverished regions of the world are struggling to obtain clean water, non−availability of which puts their life in utmost misery. Despite the fact that technological innovation provides some solution to this matter, water’s growing demand surpasses what technology can offer. A joint approach unifying various facets of human life is necessary to overcome the issue, and hence they are discussed in detail. It must be appreciated that several organisations including the U. N., representing all nations around the globe, is taking proactive steps to curb this problem by setting up various committees to study the matter in depth and taking appropriate measures to decentralise the resources to all. With the development of robust computer simulation methods, and water models, it is now possible to study water at microscopic level. Together with state−of−the−art experimental techniques the properties of water can be unravelled further. This is expected to have tremendous impact upon improving the quality of water refinement process since most of them are fundamentally of a chemical nature.
