A simplified model of combined sewer overflows to estimate event driven enteric pathogen concentrations in drinking water sources

Abstract:

Raw sewage discharges from Combined Sewer Overflows(CSO's) during rainfall can severely impact drinking water quality. Drinking water risk assessment studies in the past have not adequately captured the event driven temporal fluctuations in source water quality. This is despite the knowledge that fecal contamination of source waters is impacted by rainfall and long-term accumulated risks are affected by event driven concentration peaks. This paper presents a simple methodology to estimate the enteric pathogen loadings into the receiving water as a result of combined sewer overflows. The proposed methodology is more suitable for risk assessment studies to formulate policies for public health protection. © 2009 ASCE.
