The article deals with the problem of the negative impact of sewage gases on the sanitary and environmental conditions of the urban environment. There was performed monitoring of gases at a section of the sewer network with three observation wells as the most common type of structures. To control gas concentration, measuring equipment was installed in the wells for twenty four hours. According to the results of the survey, there was established the presence of methane and an increased content of carbon dioxide in the system. Also, a one-shot measurement of gas concentration in the environment near the wells was carried out. Based on the monitoring results at the observation wells, a low potential of the air pollution has been identified.
