Maintenance of Water Distribution Systems
نویسنده
چکیده
The efficient long term management of large-scale public funded assets is an area of growing importance. Ageing infrastructure, growth, and limited capital all result in the need for more robust and rigorous methodology to prioritise rehabilitation and renewal decisions and more importantly, to forecast future expenditure requirements. The overall objective of this research is to develop a Bayesian-based decision support system that will facilitate the identification of efficient asset management policies. This paper focuses on areas of research relating to the long term management of water distribution systems and in particular, will present: 1) A general review of existing practice and research; 2) development and initial results for an object oriented discrete event simulation, and 3) proposed future research and development.

متن کاملMaintenance Optimization of Water Distribution System: Simulated Annealing Approach
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...
متن کاملAn Optimal Preventive Maintenance Model to Enhance Availability and Reliability of Flexible Manufacturing Systems
General preventive maintenance model for the components of a system, which improves the reliability to ‘as good as new,’ was used to optimize the maintenance cost. The cost function of a maintenance policy was minimized under given availability constraint. On the other hand, in order to ensure appropriate reliability and availability, the development of the optimal maintenanc...

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...
متن کاملProbabilistic Contaminant Source Identification in Water Distribution Infrastructure Systems
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...
متن کاملVirus contamination from operation and maintenance events in small drinking water distribution systems.
We tested the association of common events in drinking water distribution systems with contamination of household tap water with human enteric viruses. Viruses were enumerated by qPCR in the tap water of 14 municipal systems that use non-disinfected groundwater. Ultraviolet disinfection was installed at all active wellheads to reduce virus contributions from groundwater to the distribution syst...
