Simulation Model For Availability Estimation Of Water Supply Pumping System

Availability of drinking water supply system is an important measure to be considered as desired quantities of water should be delivered from a water supply pumping system to all consumers at their tapping points throughout its design life. The uncertainty in the performance characteristics of mechanical components in the water pumping system such as motor, pump, and control valves affect the system availability. The reliability and maintainability of the components in the pumping system have an impact on the availability of this critical infrastructure. A Fault Tree analysis integrated with a simulation model to determine the availability of the water supply pumping system is presented in this paper. Several failure modes of various components in the water supply system are studied. The simulation results help to identify the critical pumping system elements that need more maintenance effort.
