스마트하수도시스템의 설치·관리를 위한 하수도법령의 개선방안

Abstract

Sewerage is the public infrastructure that is the significant standard of national development which significantly affects the quality of public life. Since the "Sewage Act" was legislated in 1966, the sewage project was implemented targeting expansion of sewage infrastructure focusing on the sewage system and sewage treatment facility. Thus, the public sewage treatment penetration rate of Korea in 2015 was 92.90% and the sewage system penetration rate was 79.9%. However, as the sewage facility deteriorated by time, the necessity of countermeasures arose, and along with technical development and social changes, the needs of the public regarding sewage service quality changed. Therefore, the sewage policy which was promoted focusing on the expansion of facility distribution must now turn to the direction of contributing to national convenience by significant improvement of living environment, creating clean environment, securing sewage safety. Such changes in policy refers to not only the quantitative improvement of sewage, but also the improvement of sewage quality. There is a need to suggest a new sewage service that could reinforce competitiveness of sewage industry while improving the service quality in accordance with changes of the policy. According to "Online survey regarding direction of Seoul sewage policy" conducted targeting residents of Seoul, the most critical problems of odor, flooding, cleaning of septic tank(excreta treatment vehicle etc) regarding sewage. Also, in national sewage comprehensive plan(2016-2025) established in 2015, the public's dissatisfaction was sewage odor, which notes the necessity to expand sewage system for resident convenience such as solving sewage odor. In other words, the most common complaint of the public is odor which mostly comes from septic tank, the private sewage treatment facility. If the odor of sewage from septic tank is not resolved, it is hardly possible to satisfy the needs of the public regarding sewage service. If the septic tank, the source of sewage odor is closed and the excreta is treated directly at the public sewage treatment facility, it will make urban environment more pleasant. Thus, the sewage service must be provided in the direction of closing septic tank. To provide such service, it requires improvement of efficiency of current sewage pipe and public sewage treatment facility. At this point, application of information communication technology is very desirable. The current "Sewerage Act" is a legislation that contains the system and content based on traditional sewage pipe which somewhat contradicts the installation and management of smart sewage system that applied information communication technology. In order to construct smart sewage system, this paper aims to contemplate on the installation and management of sewage in Korea (Ⅱ), draw up contradictions of current "Sewerage Act" with installation and management of smart sewage system, and suggest an appropriate improvement plan(Ⅲ).
