Abstract
For a water distribution system, it is necessary to evaluate the superiority between different valve distributions in order to improve the reliability of the water distribution system. In cases of placing more valves to an exiting system or building a new system, we suggest a methodology to select a proper valve distribution after various valve distributions are compared. The suggested methodology is based on simulations of pipe and valve failures to estimate failure impacts of the water distribution system due to pipe and valve failures. It is quantified by the number of customers out of service per pipe failure resulted from pipe and valve failures. To demonstrate its applicability, the methodology is applied to a real water distribution system with two different valve distributions and determines the superiority between those valve distributions. Also, customers out of service along with various valve reliabilities are estimated for those valve distributions to prove the effect of the valve reliability on the reliability of a water distribution system.
