Session 49 - Water and wastewater reuse | CEST2019

Wastewater, reclamation and ,reuse, (WRR) is an emerging water generation tool for combating water stress. The objective of this paper is to develop a conceptual approach which will pave the way to WRR sustainable integration in a multi-resources regional or local system. For that purpose, a holistic Water Cycle Concept has been developed.
