Abstract

An algorithm for finding the optimal sensor placement within water distribution systems is presented herein. The calculations are based on simulation injections of the organophosphate pesticide chlorpyrifos (CP) at arbitrary locations within Net1 of the EPANET software package. Hydraulic parameters and chemical concentrations of CP and its daughter compounds were calculated over 72-h duration. The methodology herein integrates an existing hydraulic analysis with a chemical analysis that accounts for the actual contaminant threshold value of significant impact on human health and its toxicity level. A pollution matrix, which provides an estimation of the affected population, is generated from the simulations and then utilized through genetic algorithms to determine the optimal sensor placement and the minimal exposed consumers.
