Large water distribution systems can be highly vulnerable to penetration of contaminant factors caused by different means including deliberate contamination injections. As contaminants quickly spread into a water distribution network, rapid characterization of the pollution source has a high measure of importance for early warning assessment and disaster management. In this paper, a methodology...

Water distribution systems are complex interconnected networks that require extensive planning and maintenance to ensure that the drinking water is delivered to the consumers. Lack of adequate water supply in urban areas is due to aging water distribution systems and inadequate maintenance of this critical infrastructure (Bhave 2003). The reliability of such deteriorating systems is continually...

Maintenance of water distribution systems is becoming a critical infrastructure problem. Good maintenance practices are necessary to extend the life of water distribution system components and an optimal maintenance effort can further prolong their useful life. The decision making problem of determining the best maintenance strategy which would minimize the total discounted maintenance cost ove...

Supervisory Control and Data Acquisition (SCADA) systems control and monitor critical infrastructure such as natural gas, oil, water, waste-water, and electric power distribution and transmission systems. SCADA systems consist of a central control center connected to Remote Terminal Units (RTUs) which directly interface with sensors and actuators connected to the physical infrastructure. Most R...

The safety and security of water supplies have come under reassessment in the United States in recent years. Issues ranging from public safety and health, ecological, and national security are under consideration. The terrorist attacks on the United States on September 11, 2001 and the subsequent delivery of Anthrax-contaminated letters through the mail raised concerns about protecting U.S. cit...

Infrastructure systems of many U.S. cities are in poor condition, with many assets reaching the end of their service life and requiring significant capital investments. One primary requirement to optimize the allocation of investments in such systems is an effective assessment of the physical condition of assets. This paper addresses the physical condition assessment of drinking water distribut...
