Review on Codes and Application of Urban Rainwater Harvesting Utilization: Focused on Case Study in South Korea

Abstract

Recently, Urban Rainwater Harvesting (URWH) has become more important in South Korea. Rainwater utilization has the potential to solve many urban environmental problems. Central and local governments published a series of policies and regulations. Especially, proper management by URWH facilities improves the efficiency of rainwater utilization and the adaptation to climate change and variability. Thus, this paper reviews the regulations and the developing technologies (i.e., harvesting, infiltration, water quality control and reuse) for efficient rainwater harvesting and utilization in urban areas through case studies.
