Sustainability Of Dual Water Distribution Systems For Fire Flow Condition, Nazli Yonca Aydin, Larry Mays, Theo G. Schmitt

International Conference on Hydroinformatics

The objective of this study is to compare the sustainability of current water systems when a dual water distribution system (WDS) is used for the non-potable water purposes of fire protection, irrigation, and toilet flushing. Sustainability of urban WDS is evaluated in terms of hydraulic efficiency and water quality. The first step is to assess sustainability of an example urban WDS by using sustainability index (SI). The SI is measured by reliability, resiliency, and vulnerability performance indices. Pressure and water age are selected as main parameters to determine sustainability. Once the SIs for pressure and water age are calculated by …
