This study proposes a new approach to estimate available consumable water for human activities (ACW) in a basin based on precipitation, natural ET, and uncontrollable outflow, thus capping water use for human consumption in a basin. The ACW is illustrated for the Hai Basin in North China, ...
Human beings use a little less than half the water available worldwide. Yet shortages and droughts(干旱) are causing starvation and poverty in some areas and industrial and agricultural by-products are polluting water supplies. Since the world’s population is expected to double in the next 51 ...

Of that, less than one percent is available for human consumption. Most of it is either salt water, frozen in polar ice caps or inaccessible (i.e. too far under the earth’s surface to be extracted). The fresh water that is available for use isn’t just used for human consumption. ...
Extraction of groundwater for irrigation and home and industrial use turns out to be an important missing piece of the puzzle in estimates for past and current sea-level changes and for projections of future rises
use of such water is done for alternate activities like washing, flushing and so on. While talking about the hesitations in using such treated water I would like to bring to your attention that many times fresh water is available, in abundance, at cheap rates than the treated water....
