Abstract

The Greeks were the first to use the basic water supply elements collectively to serve the needs of the entire urban community, including obvious display and aesthetic uses. They were also the first to divide water into the three categories of potable, sub-potable and non-potable on the basis of source and use [1]. The Greeks preferred to obtain potable water, that is., drinking and cooking water, from a flowing source such as a spring or fountain. This accounted for less than six percent of their total water supply [1].Cisterns primarily supplied water for the sub-potable category. It is interesting that the Greeks also generally reused their water [1], what is today referred to as grey water. Non-potable wastewater, runoff, was used for irrigation, baths and sacrificial basins [1].
