Aims: Regarding water as the main source of brio, not only its quantity and being availability is vital, but also its quality must be considered. This study was done in order to determine the correlation between physicochemical BOD5 and microbiological parameters (FC and TC) in the Kashan University of Medical Sciences wastewater effluent of activated sludge system. 

Materials & Methods: This descriptive study was done from July to October 2012 at Kashan University of Medical Sciences. A total number of 130 samples were taken on different days of the week over a 4-month period from effluent, randomly. All of the taken samples were transferred to the water and wastewater laboratory for analysis, immediately. The SPSS 16 software and regression test for were used to analyze the obtained data, ultimately. 
Findings: The mean value for BOD5 was 11.27±5.43mgL­1. The mean value of TC was log1.62±0.32. A linear correlation (F=312.9 p<0.001) was observed between TC and BOD5. The mean value of FC was log1.42±0.31. A linear correlation (F=298.3 p<0.001) was observed between FC and BOD5. 
Conclusion: BOD5 parameter can be used to predict the wastewater quality instead of TC and FC.
