Indirect reuse of reclaimed wastewater for agriculture in Korea.

Reclaimed wastewater has been considered as an alternative water resource due to the shortage of established water resources and increasing water demand. Reclaimed wastewater having relatively constant volume throughout the year and abundant fertilizer ingredients is widely used for agricultural irrigation in Korea. The objective of this study is to introduce the project of the development and application of wastewater reclamation systems for indirect agricultural reuse. The project could provide cost-effective systems and guidelines for indirect reuse of reclaimed wastewater for agriculture. Two reclaimed wastewater irrigated monitoring sites, Byeongjeom (BJ) and Osan (OS), and one monitoring site of conventional water irrigation, Yongin (YI), were selected and will be monitored and analyzed about the crop growth and yield, water quality, and soil characteristics from 2011 to 2014. We anticipate that the findings from this project could contribute to safe indirect wastewater reuse for agriculture in Korea.
