摘要
The regional water imbalance due to climate change is becoming more serious. Unparalleled water shortages have been experienced such as water level degradation of eight major dam in South Korea during all season. Smart Water Grid, making full use of a variety of water sources, and ensuring the efficient supply through ICT, has been proposed as an alternative. First, Representative cities by location type were selected to design a SWG Standard Model through research of domestic and international cities types (inland type, the coast type, the island-like oasis-type) and then standard models by location type were established in accordance with selecting the optimal way from technology performance assessment process using the AHP method. In this paper, case study of process for standard model establishment of inland type among four types was introduced.In general inland type water have been supplied through a single water resource in case of abundant source for water supply, which provided for cutting off the water through other areas, and emergency water supply pipeline connection. This case are vulnerable to water pollution and accidents, when the number of water treatment plants use the same intake source and also it is difficult to secure much alternative water resources by region. D Metropolitan city which achieved in high score of SWG suitability index was selected as represented city of the inland type standard model in terms of water resources, industry, population, finances and ICT infrastructure.It is planed that water was produced by supplying raw water to the Maegok and Munsan water treatment plant through installation of riverbank filtration facilities (242 thousand ㎥ / day) in the Nakdong riversides to conjunction with the existing Water intake plant according to change of water quality in Nakdong River. Jukgok water treatment plant, which supplies industrial water have 80% of water self-reliance rate and 56% of active water resources utilization rate by providing the reuse of treated sewage. It was designed that variable intake technology depending on water quality changes considering the economic and operational efficiency is possible thorough SWG. River water filtered into the main intake source is a main water supply in emergency and reused water treated from sewage treatment plant was planned for supplying industrial water.
