In order to provide a new concept of water supply system that is more sustainable into and beyond the 21st century, small and decentralized water treatment plants and distribution systems have been suggested for ensuring water security which consists of stability and safety, reserving redundant water for emergency and preventing secondary contamination in distribution. The decentralized water supply systems can ensure water stability and safety with alternative source such as ground water, rain or seawater desalination. They reserve water enough to cope with emergency. Also, decentralization can shorten pipe distance from small plant to each consumer to reduce secondary contamination. The water treatment plant (WTP) for the decentralized water supply systems need to the smaller WTP. Owing to a limitation in the smaller sizes of WTP, developing design and construction technologies is inevitable for compacting of water treatment processes. In addition to the technologies discussed above, pressure systems of multistory structure should be evolved to achieve the WTP for the decentralized water supply systems. The present study focuses on the Master plan of decentralized water supply system and engineering development of multistory water treatment facility.
❚ Benefit assessment for DWSS
■ This study is to provide a basis for promoting the economic evaluation in the future commercialization of decentralized water supply system by estimating the value of a quantitative objectivity.
■ Method of the survey as a method for estimating benefits and Contingent Valuation Method (CVM) of the decentralized water supply system was applied to the amount estimated by willingness to pay.
❚ Economic evaluation for DWSS
■ Decentralized water supply system was to ensure the feasibility of the business through the economic analysis of whether compared to traditional centralized water supply system is worth the investment economically.
■ Decentralized water supply systems analyzed the economic feasibility to target the H city in urban areas and among the new urban areas because of the Saemangeum area is not highly feasible region that is also an existing installation facility.
❚ Practical application and commercialization plans
■ Multistory water treatment facilities only area that can be applied to the area where you plan future capacity expansions to increase the aging and complaints about the existing water facilities, the existing industrial complex needs living among the local water supply, the required area of a small water treatment plant improvements, altitude water treatment facilities, such as a local installation is required.
■ Decentralized water supply system projects considering the possibility of economic conditions and overseas companies in order to advance was given a personalized business models based on segmentation by market successfully to enter the market.
❚ Establishment of emergency water standard
■ Through analysis of water supply suspension case study, surveys and water intake source pollution, standard of emergency water supply was established as aspect of water security.
❚ Supplementation draft for regulations
■ Decentralized water supply and complementary review of the various aspects of the system laws and regulations applicable to the inside presents legal review was conducted of the water service method, such as current and capital maintenance plan.
■ The enhanced stability of the supply of water to provide the amendment to increase the utilization of renewable energy.
❚ Master plan of DWSS
■ By anaysis of water supply network and distributing reservoir plan of H city as target area, applicability and benefit of decentralized water supply system.
❚ Development of BAT (Best Available Technology) matrix tool
■ Regional water quality characteristics were identified and, specific contaminants were selected.
■ Treatment process for selected contaminants was examined and categorized.
■ BAT matrix tool was developed to present the best target-specific contaminants process.
❚ Flow simulation of Multistory Water Treatment Facility
■ Computational Fluid Dynamics (CFD) techniques were used for flow simulation was performed for the flow stability of the multistory water treatment facilities derive optimized hydraulic design improvements.
❚ Demonstration facility design
■ Demonstration facilities with capacity of 1,000 ㎥/day were designed to validate Engineering technologies of multistory water treatment facility.
■ Direct coupling system (Tankless system) design technology which can reduce equipment and operation cost, applied on demonstration facility design.
■ Design of multisotry water treatment facility was improved on the basis of operation results of demonstration plant.
❚ Commercialization scale facility design
■ Process of Engineering development of multistory water treatment plant was design plant → design of demonstration plant → manufacturing of prototype → construction of demonstration plant → operation of demonstration plant → design of commercialization scale facility.
■ Design technology was advanced and commercialization scale facility was degined on the basis of operation results of demonstration plant.
■ In order to assess the feasibility of multistory water treatment facility, capital cost of the facility compared to conventional water treatment facility.
