| 초록 | At global level, water source on Earth is abundant in natural but the water source which is allowed to be accessed by human is not enough. The distribution of the water on Earth indicates that over 97 percent is salt water, and the remaining is freshwater including glaciers, groundwater and surface water. Also it is noted that only 0.3 percent of the freshwater is surface water which is allowed to be easily used for human. Climate change causes more frequent and severe rainfall and snowfall in some regions, and intensive drought in other regions, resulting in significantly reducing the availability of renewable water resources for human. In addition, the centralization of population into cities and industrial areas makes it difficult to use various water sources. In current, about one-third of the world’s population (= about 6.8 billion in 2010) faces moderate to severe water shortage. An estimated 25% of the world population lacks access to clean drinking water and protection from waterborne disease [U.S. Census Bureau - World POPClock Projection]. According to the report of UN (2006), Korea has belonged to water stress countries (water availability per capita = 1000~1700 m3/capita-year) along with Denmark, Poland, India and South Africa etc. As result of water scarcity in some regions in Korea, water reuse has been applied to supplement water source. There are about 36 water reclamation plants in Korea with municipal and industrial purposes. The municipal reuse is for activities requiring low quality water (like toilet flushing) but also for human consumption. Korea was ranked 16th in total volume of water reuse (m3/d), in which China was 1st because reuse of untreated wastewater was included in the total volume. According to the data on reuse of treated wastewater, USA was ranked first and Korea was 13th. |
