Cheongju city is executing a basic sewage maintenance plan for the systematic understanding of the sewage facilities, efficient preservation management, and reformation of the existent sewage facilities, in order to prevent the contamination of water and to preserve the neighboring environments. The new business constitute approximately 6% of the entire facility production, and renovation business constitute approximately 1.5% every year according to the statistics information of the last five years. This research provides effectiveness and reliability for sewage construction, and improvement in service for the civilians, through the efficient management of various documents, construction fees, design drawings, photographs, and construction background for the annually made constructions with the development of the effective management system for the sewage work.

With rapid expansion of the water market and growth of water companies, the recent trends in international water industry show that standardization of service activities concerning management of water and wastewater system (ISO/TC 224, to be issued in the second half year of 2007) is expected to have a large influence on the global water market including liberalization of water service market. In the Draft International Standard(DIS) of ISO/TC224, Performance Indicators(PIs) are suggested to estimate the service activities relating to water and wastewater treatment facilities. PIs have been developed in many countries including some international organization(World Bank, IWA and etc.) for service benchmarking. To evaluate public service level and establish plans to improve service level of wastewater utilities, we developed PIs for 120 items and applied them to 10 sewage utilities in the consideration of their scales, circumstances and conditions. In this study, we verified the applicability of the developed performance indicators(PIs). So, we concluded that PIs developed for the purpose of this study can be a useful tool applicable to objective evaluation of the service level of sewage utilities. Using the evaluation tool of PIs developed, it can also be used as a benchmarking tool in this industry as well as for enhancing the efficiency of operation and management of the sewage system. It will also contribute to the water resource management through determination of investment priorities based on the evaluation results and to raising international competitiveness of the domestic sewage utilities to meet the future opening of the water market.

The sewage system was continuously distributed as a concept of public service and protection for water system such as wet-land, resulting in deterioration of the management of sewage management institutions. Accordingly, under the leadership of the central government, various sewage policies are being promoted to streamline the management of sewage management institutions. The main points were related to costs, and typical characteristics include wastewater cost and wastewater discharger cost. In this research, the current status and characteristics of the wastewater discharger cost of 71 local governments in Korea were analyzed. As a result, 41 places (57%) were found to be less than 1,000,000 won/m³ to 2,000,000 won/m³, with an average was 1,990,653 won/m³ (median was 1,918,000 won/m³). In addition, the rate of wastewater discharger cost was increased when the wastewater discharger cost was higher stage. The influential parameters of local governments, which were relatively correlated with the wastewater discharger cost, were analyzed as the rate of recovering wastewater cost and financial independence rate. The results of this research could be used as basic data for wastewater discharger cost, and future researches are needed on how to calculate the appropriate level of wastewater discharger cost.

최근 들어 U-City 구축 사업을 수행하고 있는 대다수의 지자체에서는 U-City건설지원법에서 규정하고 있는 U-도시기반시설의 서비스 모델을 정립하고 체계화 하기위해 노력하고 있다. 그 중 공간정보 수요가 높은 도로, 상 하수도 시설물은 국토해양부의 주관하에 90년말부터 현재까지 매칭펀드 사업을 통해 DB 및 시스템을 구축하도록 유도해 왔다. 그러나 정부차원의 이러한 사업이 지자체 지리정보 담당부서와 지하시설물 관리 담당 공무원들 중심으로 단순히 공간정보의 조회 및 편집차원에서 추진되고 있어 활용에 대한 한계가 발생하고 있다. 본 연구는 국토해양부에서 주관하고 있는 '지능형 도시 지하시설물 관리 기술 개발' R&D 사업을 통해 이러한 한계를 극복하고 기존 상 하수도 단위시스템에서 제공하는 조회 및 편집기능이외에도 USN 및 RFID를 적용하여 활용할 수 있는 지능화된 지하시설물 관리업무를 도출하고, 기존 상 하수도 단위시스템과의 연계 모델을 제시하고자 한다.

스마트시티 개념의 등장과 함께 국민의 삶의 질에 대한 정부의 관심이 증가하고 있다. 국민의 삶의 질을 향상시키는 것은 하수도와 같은 도시기반시설이며, 정부에서는 이를 지속적으로 유지관리 하여 주거환경 개선, 공중위생관리, 침수방지 등을 위해 노력하고 있다. 최근에는 하수시설의 노후화 와 서비스 범위의 변화에 따른 하수 서비스 품질에 대해 국민적 관심이 증가하고 있다. 또한 급격한 기후변화에 따른 도시 침수와 같은 재해가 빈번하게 발생함에 따라 재난 관리 측면에서도 하수도는 매우 중요한 비중을 차지하고 있다. 본 논문에서는 모바일 디바이스와 IoT 기술을 활용하여 하수시설 모니터링 시스템을 설계하였다. 제시하고 있는 시스템은 하수시설의 데이터를 수집하고 모바일 어플리케이션을 통해 사용자에게 알려준다.

In 2009 the Korea Ministry of Environment announced 'A Comprehensive Plan for the Improvement of Sewer Service in Rural Area' aiming at reduction of the sewer service gap between urban and rural areas as well as improvement in the residential environment of the rural area. According to the plan, the sewer system supply rate for the rural area is expected to reach up to 75% until 2015 with the budget of 4.7 trillion won (Korean currency). It is not certain, however, that the increase in the sewer system supply rate will accompany improvement of water quality in receiving water because several veiled problems that can occur in small-scale sewer treatment plants are poorly addressed in the plan. In this study, those issues for the small-scale sewer treatment plants and their solutions were discussed based on a case study in which we investigated 19 treatment facilities at two rural regions in Gyeonggi province. This study also included strategies useful for the plan. From the results of investigation, some problems, e.g., high hourly variations but low in flowrates and low mass loading were commonly identified. Although operation parameters in sewer treatment plants require to be modified depending on the mass loading, most of the plants were operated with the initial design parameters which causes the decrease of removal efficiency. In the intensive diagnosis, we arranged and applied solutions (e.g., flow equalization, air on/off time control, etc) to the two selected plants and found out improvement of effluent water quality, especially organic matters (COD and SS) and T-N with better denitrification performance.

In this study, we derived seven customer value factors to evaluate the levels of service in wastewater utilities required by customers. Levels of service according to the customer value were categorized into environmental amenity, accessibility of wastewater service, affordability of wastewater charge, quality of wastewater service, health and safety of wastewater service provision, reliability and responsiveness of wastewater service provision, and satisfaction of customer service. To investigate the levels of wastewater service, questionnaires were prepared according to the customer value factors, and the questionnaire survey was performed with 800 adults in all over Korea including male and female samples. The comprehensive satisfaction score for the wastewater service was 57.5 points, indicating a slightly good satisfaction level. The detailed analysis of the result showed that the satisfaction level was high in the wastewater service accessibility and call center service provision but it was relatively low in the river water quality and nasty smell of wastewater. It was concluded that the quality of wastewater service and customer service satisfaction need to be elevated primarily in order to improve levels of wastewater service required by the customers.
