Title

Sensor Placement in Water Distribution Network Under Dynamic Variations of Commen Water Quality Parameters

Pages

  67-80

Abstract

 Detection of pollution in any water distribution network (WDN) is essential to maintain public health. Recent researches have demonstrated common water quality indicators (free Chlorine, pH, Electrical Conductivity, … ) response to contaminants, which can facilitate the pollutant detection in WDNs. In this research, EPANET-MSX model is used to simulate the realistic responses of common water quality parameters to a pollutant event in WDN, represented in example 3 of EPANET 2. 0. The aim of the study is to apply EPANET-MSX to trace Chlorine changes in response to the potassium cyanide injection order to optimize sensor placements WDN. Optimal sensor placement is derived based on coupled EPANET-MSX _ PSO (particle swarm optimization) framework. PSO is implemented as single and multi-objective algorithm. The objectives of the study are to reduce the pollutant detection time, increase detection likelihood, and reduce the contaminated water consumption as single and/or multi-objective problems. Studies on the sensor numbers, ranging from one to five, indicate 1-the pollutant detection time has decreased from 36. 22 to 17. 41 hours, 2-the pollutant detection likelihood has increased from 28. 8% to 68. 6%, and 3-the contaminated water consumption has decreased from 31. 87 to 3. 78 m3. The results show direct relationship between 1-pollutant detection likelihood and detection time, 2-pollutant detection likelihood and contaminated water consumptions, and 3-pollutant detection time and contaminated water consumption in multi-objective problems. Also, the location of the high-demand nodes in WDN and the contamination events occurrence can affect the location of the Sensors.
