Abstract Water distribution network (WDN) is an important infrastructure which suffers from failures. A risk-based decision making required for maintaining the integrity of water mains effectively. This paper presents a framework for risk assessment of pipes in a WDN for maintenance prioritization. Because pipe failure can lead to various types of consequences, a fuzzy inference system (FIS) is proposed to aggregate different consequences. The properties of algebraic connectivity (AC) from compl...

Water Distribution Network (WDN) is an important component of municipal infrastructure. Many municipal water distribution systems are exposed to harsh environment and subjected to corrosion with age. Many of the water mains in North America are close to or have exceeded their design life and are experiencing a number of issues associated with leaks and breakage of the water mains. Maintaining structural integrity of the water infrastructure with the limited municipal budget has been a challenge....
