Research on institutional improvements regarding the utilization and management of groundwater discharge in urban areas
Ⅰ. Background and Objective of the Study
o Large-scale discharge of groundwater from projects designed to develop underground spaces in urban areas needs to be actively utilized and managed to conserve groundwater and ensure the integrity of water circulation systems. Under the Groundwater Act, etc., there are regulations that require the establishment of reduction measures and utilization plans for discharged groundwater generated from subways and buildings. However, the effectiveness of current systems in place is insufficient in terms of both effective management and utilization.
ㅇ The main purpose of this study is to find ways to improve the management system, including the legal framework, to effectively manage and utilize discharged groundwater in urban areas. This study also identifies the current status and issues pertaining to systems utilizing and managing discharged groundwater, and establishes the direction of relevant policies for effective groundwater discharge management. Based on its findings, this study ultimately proposes various measures and plans to improve legal systems governing the management and utilization of groundwater discharge in urban areas.

Ⅱ. Characteristics of Groundwater Discharge in Urban Areas
o Previously published information on discharged groundwater and its usage suggests that more groundwater is being discharged in urban areas to the extent that the volume of discharged groundwater exceeds the capacity of groundwater developed and utilized. Since groundwater discharge is mostly used for the maintenance of rivers, it greatly con
