The waterworks company is in charge of managing water facilities buried underground, and the management has been centered on manholes. However, since there is no standard management manual, it has been impossible to introduce and operate a systemized managing tool by water service providers and managers, and manhole management has been carried out by individual data recording personnel for each water service provider. When the management is carried out individually, the data to be shared by other waterworks managers tend to be privatized, and consequently, it may become a big obstacle to proceed with many civil works such as emergency leak repair, road excavation, replacement of old buildings. This report introduces RFID (Radio Frequency Identification) system which is based on the magnetic field capable of IOT. It also describes the necessity of leveraging the system for smart managing of pipe management record that has been done by hand writing. The RFID system includes RFID marker, data reader, portable computer operating program, and data base server operating program. In this system, the data is managed with a single communication device, and it would be possible to share the information on the underground facilities and water treatment facilities. This RFID technology is expected to provide water service providers with opportunities to develop more scientific and modernized underground facilities information systems.

The service for waterworks is important infrastructure structuring the cities and the public properties affecting the health and the abundant lives of the residents at the same time. However, the waterworks project still has many problems in reality in spite of the continuous efforts from the nation, local governments and many related people in waterworks projects. From the aspect of the situation, this purpose of this study is to review the actual operation state and the operation principle on the basis of the accidents in the system and to suggest the policy leverages for accurate diagnosis of the waterworks project and for the efficient operation. The operation structure of the service for waterworks is the complicated system showing the overlapped forms of the relation with other various factors. Moreover, as this has been influenced by other external environments, it has flexible features that can be changed by unexpected factors even if the internally close causality has been established The domestic local operation of waterworks have been divided by an administrative district and it causes inefficiency in the aspect of the country and the local government with small sized of budget faces the insufficient investments. These phenomena have been shown in some small sized areas located in Chungcheongbuk-do and, making a realistic suggestion by the related local government to improve the waterworks operation project is urgent. For this reason, this study is to lead the policy leverages to increase the efficiency of the service for waterworks and to stabilize the structure of virtuous circle in the system. At first, the reformation of the waterworks structure should be performed after the various supports and system maintenance. At second, the service quality should be improved through the creativity in management and the consideration of the efficiency by the participation of private enterprises for waterworks service. At third, through the specialized waterworks operation, the quality improvement of the waterworks and satisfying the standard of natural environment should be related. In this context, the fundamental solutions for the problems of domestic waterworks service and finding realistic alternatives are considered to be the priority for the waterworks project to be operated efficiently.

3D-based BIM(Building Information Modeling) technologies can be utilized effectively as a means of systematic management of facility information for safety assurance and effective maintenance of waterworks facilities. In this study, BIM models of water treatment facilities that can be used as basic data for BIM-based maintenance of waterworks facilities were developed. Information exchange and generality of the developed BIM models were evaluated by conducting interoperability analysis of IFC(Industry Foundation Classes) conversion models. In addition, the application of COBie(Construction Operations Building information exchange) was recommended as an effective countermeasure to deal with technical limitation regarding exchange and utilization of facilities-related information through current IFC models. The results of this study can contribute to the development of BIM-based maintenance system for waterworks facilities.

This paper presents application of RCM(Reliability Centered Maintenance) in waterworks system. The reliability-based probability model for predicting the failure probability is established and FTA(Fault Tree Analysis) is proposed to considering RCM. To calculate failure probability, Weibull distribution is usually used due to age related reliability. FTA is an engineering analysis which is using logic symbols. The real historical data of CMMS(Computerized Maintenance Management System) make full use of case study for waterworks system. Consequently, the RCM would be likely to permit utilities to reduce overall costs in maintenance and improve the total benefit.

A water management system is developed to reduce the unit cost of production in wide-area waterworks. Improving productivity in waterworks is to save power rate. We suggest a method to schedule the supply of water according to the time-varying power rate and pump control scheme. Water pipeline analysis package (SynerGEE Water) is utilized to obtain optimal pump control solution adaptation to water demand. Our evaluation results show that developed scheme is more efficient than the conventional.

Brebbia's model has been analyzed to develop the appropriate waterworks management system in Korea, and compared with the conventional models such as EPANET, WaterCad, and InfoWorks. The hydraulic theory of the models was analyzed. Each model's numerical techniques, required parameters, input data and operational methodologies, restrictions, practical applicability and other aspects were investigated. In order to check the validity of Brebbia model, the comparative analysis with EPANET, WaterCAD, and InfoWorks models was performed for linear and nonlinear cases. To find out advantages and disadvantages of each model, the modeling was performed for a simple network and for more complicated A city waterworks system, and the three models applicability was examined. Finally, optimal modeling technique and a model suitable for the use in Korea was suggested, and the problems related to present projects of waterworks management system in Korea were analyzed.
