Water re-use for sustainable irrigation

Abstract

The wastewater reuse is part of measures to increase the availability of water resources and is combined with measures involving infrastructure for transporting these resources from areas of high availability to others that has not. Based on a mode for the reuse of the resource, is also necessary to identify treatments of aging and their intensity application, which will the water be submitted to become suitable for intended use. In addition to sanitary aspects, economic, environmental and social factors are not to be underestimated; the economic one, in fact, plays a key role especially in developing countries, because the use of reuse technologies involves financial investments not always affordable. This paper summarizes the possible applicable technologies for the reuse of wastewater for irrigation purposes, highlighting the aspects previously mentioned and describing a case study. © 2013 WIT Press.
