As natural disaster like desertification and flood by climate change happen, water management has been interesting more increasingly than before. Especially, South Korea, one of countries of water shortage, makes effort LID using rain-water with the center of government. At the houshold area like apartment, the main system using rain-water is collecting system. Rain-water collecting system is side gutter collecting system and round collecting system. This study aims at evaluating the life cycle cost comparing presently applied collecting systems with drain collecting system which was developed. As a result, life cycle cost of drain collecting system was effected 53% reduction besides of round collecting system.

By climate change, natural disaster like flood, desertification, elnino and etc happens more than before. Adaptation for climate change becomes important as well as respond globally. One of main issue for adaptation is the water circulation recently. Each countries has been developing technology facilitating water circulation. South Korea also develops low impact development(LID) using rain-water. The rain-water collecting system needs to establish for circulating the rain-water in the household area. The side gutter collecting system and round collecting system have been applied as rain-water collecting system. This study aims at evaluating carbon emission in the life cycle of construction, operation&maintenance, demolition and disposal comparing them with drain collecting system which was developed by life cycle assessment(LCA) methodology. Drain collecting system emitted 2.82 ton CO<sub>2</sub> eq./set, round collection system emitted 27.65 ton CO<sub>2</sub> eq./set and side gutter collection system emitted 21.54 ton CO<sub>2</sub> eq./set. From the result, drain collecting system concluded to reduce over 87% of CO<sub>2</sub> emission in the life cycle besides of other two collecting system. Thus decision-makers need to consider to apply LCA for reducing CO<sub>2</sub> emission designing rainwater collecting system.
