　　This study investigated the comprehensive performance of a tap water supply plant using emergy analysis.Traditional emergy-based indicators (including emergy yield ratio (EYR),environmental loading ratio(ELR),sustainability index(SI),emergy investment ratio (EIR),and percent renewable emergy (%R)) and a proposed indicator-cost per unit pollutant eliminated (CUPE,used to evaluate the cost of pollution removal) were adopted to assess this tap water supply system.
