Abstract Majority of Wastewater treatment plants in Thailand faces the problem of over design, as this is based on the Biochemical Oxygen Demand (BOD) content of the inputted wastewater having a lower concentration than the efficiency of the design system. To meet the purpose of this study the findings of the optimum recommended BOD concentration for the effectiveness of the treatment and high operating costs. Water samples were collected from January 2009 to December 2017 (N = 90). The results showed that the BOD concentration differ shows an inconsistence variation over time as this is due to the wide range of wastewater sources from various activities. The results of this paper showed that the recommended BOD concentration for the wastewater treatment plant should be 80 mg/L in the vicinity of the city, while 60 mg/L is the recommended concentration for wastewater that has been transited for over 5 hours into the treatment plant system away from the city, as the transferring processes of the wastewater through the close pipeline resulted in an anaerobic treatment which reduces the BOD concentration. Thus, the overall concepts suggested that the BOD concentration entering the wastewater treatment plant of 80 and 60 mg/L respectively falls under the 80% confident range.
