Environmental data accumulate heavily because of automatic measuring system such as TMS. This study is on how to analyse the massive wastewater data and to find useful operation points for its improvement. This work may extend to an automatic WWTP in near future. As a result of analyzing the water quality of the selected four sewage treatment facilities in Cheonan-Asan for 4 years, and analyzing it with a large amount of data, the BOD removal efficiency showed a constant removal efficiency of 98~99% in all 4 areas. The E. coli removal efficiency was close to 100% in the K, N, and H regions, but the S region showed a low removal efficiency of 84~88% compared to other regions. As for the SS, the rest of the regions except for the H region showed a common trend of decreasing the value of SS as the temperature increased, and the value of T-N showed a common gradual decrease in the rest of the regions except for the N region. The value of T-P was mostly maintained at a constant value with a slight increase or a slight decrease in all 4 regions.
