Abstract

Comprehensive environmental impact of wastewater treatment plant (WWTP) was evaluated with life cycle assessment (LCA) methodology based on ISO 14040. As environmental impact assessment method, Eco-indicator 95 and Eco-indicator 99 were used. The studied WWTP had a capacity of $100,000m^3/d$, and its life span of civil structure and main machinery was designed to 40 years and 20 years, respectively. As the results, more than 95% of environmental impact was produced by using electricity and chemical use in operation stage. In construction stage, temporary shoring facility was the major reason of environmental load, however, its impact was much less than those by operation utilities.
