widely recognized “water poverty line” of 1000 m3
per capita
per year (Water Strategy of Jordan, 2008–2022Water Strategy of Jordan, 2008–2022). This critical situation is further aggravated by
the new influx of more than 1.5 × 10

on the already exhausted water resources. In such a situation the
country has to optimize management of its limited water resources
(Abu-Sharar and Battikhi, 2002). Oster (1994) acknowledge the

and municipal needs grow in a pace higher than the growing World
population. Because of the growing shortage in fresh water supply for irrigation, the Jordan’s Standard Specifications of Reclaimed
