| Abstract |
The purpose of this study is to calculate the capacity of reclamation and reusing water in the housing site, and analyze the economic efficiency for public water reclamation and reusing system. The reclamation and reusing water was formulated by the function composed of the reclamation and reusing water coefficient(RRWC) and the size of housing site. The result of the economic assessment indicated that the proper facility size to secure the national and individual economic efficiency should be able to handle 4,000 tons/day and over (4,000 tons/day is applacable to the size of residential area of 1.2 million pyeong (=3.3㎡)), and for each usage, the business and commercial zones would have the best economic efficiency. And, the above-mentioned facility sizes were proved to be the optimal models by verification of maintaining the available river water quantity building up the ecological river in the housing site. Therefore the application of the optimal models for the public water reclamation and reusing system has the important implication of securing water resources in response to a possible water policy and a useful means to build up the water-friendly environment. |
