We suggest that using the artificial wastewater for the experiments in sanitary engineering. The wastewater from the septic tank of our college is used on the experiments in sanitary engineering for 4th year students in department of civil engineering. The safety management was concerned for sanitary conditions. Therefore, the artificial wastewater with peptone, NaCl and kaolin was used for the experiments in sanitary engineering. The similar data were obtained at 15 kinds of water quality analysis, when we used the wastewater from the septic tank. However, the difference of NH3-N and PO4-P data were higher as compared with the wastewater from the septic tank data. The method of explanation for the artificial wastewater has to be improve. These results indicate that using the artificial wastewater on the experiments in sanitary engineering has a few improvement.
