Abstract

The issue of sustainable development emphasizes the undesirable effects of development in ecosystems . One of the issues raised in the ecohydrology of arid areas is the management of urban wastewater. The purpose of this research is to investigate the possibility of using Sabzevar wastewater in the restoration of Drake-Brabid desert region. In assessing the efficacy of wastewater quality and its effects on the ecosystem , the quality of wastewater was compared with standard values in the uses of agricultural sectors, artificial discharge, crop pattern, irrigation, livestock and wildlife. For determination the possibility of wastewater re-use Delphi technique was evaluated by effective factors. The SWOT model was used to integrate, analyze information, decide and propose a strategy tailored to the design. The results showed that the total score of the obtained external factors was 2.992 and 2.917for internal factors. respectively, which resulted in the invasive pattern as a result of the proposed design. The presence of natural reeds with the potential for refining, water storage in the Kalchoor River and the high adaptability of desert species are factors that allow us to use wastewater and revive its ecosystem.
