This study was conducted to show the odor emission characteristics between the well maintained environment fundamental facility and the poorly maintained environmental facility. It also draws major components of odor emission based on facilities, stages, and suggest the proper way to reduce the level of odor for insufficient facilities. Insufficient facilities" air direct sensory and air dilution value levels are following: foodwaste ＞ livestock ＞ wastewater ＞ night-soil ＞ sewage. For the sewage and waste water facilities, the common characteristic of odor emission on each fundamental facility showed higher air dilution value in depositing reservoir and concentrator. And sulfur and aldehyde compounds came out to be the major odor causing components. In the case of night-soil and livestock facilities, the air dilution value was high in flow equalization tank and liquid erosion tank. And sulfur as well as ammonia component was the major malodorous substance. Foodwaste facility showed higher air dilution value than other facility, which sulfur and acetaldehyde compounds were acting as major malodorous substances.
