The article presents an analysis of the study of variation of wastewater flows in two cooperating pumping stations
A and B in the period from 2014 to 2017. Based on the analysis of daily, monthly and annual flows, the factors
characterizing the unevenness of the pumping station’s operation, both in each year and in the long-term profile,
were determined. The daily Nd and hourly Nh factors for both pumping stations, are higher than those presented in
the literature on the subject and utilised for the sanitary sewage system design. The influence of weather conditions on the operation of pumping stations A and B and their cooperation was confirmed by a statistical analysis of the impact of incidental waters on the actual monthly sewage flows.
