Since the early 1980s, PUB has been conscious of the need to manage the water supply network efficiently and to account for the amount of water distributed through the network. This concern is primarily motivated by PUB's goal to provide a high level of service to customers with reliable supply of water at affordable cost. With the strong support of the top management and the active participation of everyone in PUB, an Integrated Water Network Management System has been adopted to ensure that leakage in new networks is kept to a minimum through proper planning, design and the use of good quality materials that are installed with good workmanship. Losses in existing network are reduced through network management and leakage controls as well as accounting for water distributed with full and accurate metering. Consequently, these deliberate efforts have enabled Singapore to achieve one of the lowest Unaccounted-For-Water in the world (below 5%).

Main goal of Road Network Management System is to ensure safety and continuity of road traffic on road network with low intensity and lower technical requirements. This is achieved with pavement management system (main component of road network management system). Most countries developed custom Pavement management systems (PMS) based on deterministic or probabilistic approach. Local road administrators of low level road networks often lack the software equipment such as HDM-4, RoSy, Exor, etc. These and similar PMS Most PMS, however effective, are often cumbersome, demanding in regard to energy, know-how and software equipment. The majority of local road administrators of rural road networks thus resort to non-effective reactive maintenance strategies. This article describes an easy to use method, based on predetermined maintenance repair & rehabilitation standards. Secondly, a simple method, based on road user cost, is introduced that administrator can use to prepare a list of road section eligible for repair according to their repair priority.

With the rapid development of computer network, the network architecture is increasingly complicated; the scale of network extends continuously. Therefore, the functions and positions of the network management are also more and more important. The Web-Based network management, making users manage the network and system expediently and simply, combining Web technology and modern distributed network management technology, which can also be updated and customized easily to meet the different needs, is an important direction of the development of the network management technology in the future. This paper proposes an a SNMP-based Web network management system using B/S structure, which has features of flexible structure, easily extensible, user-friendly features and so on.
