The study, which included a 7-month period of observation during dry and wet weather, analysed the operation of
three wastewater pumping stations working in a selected gravity sewer network located in the southern part of the
Małopolskie Province.
The aim of the study was to analyse the hydraulic loads on wastewater pumping stations with incidental waters. The
study analysed parameters characterising the operation of the pumping station, such as the volume of pumped
incidental waters, the number of pump starts, their operating time, energy consumption and the resulting carbon
footprint.
During the entire study period, a total of 205 m3 of incidental waters flowed into the P1 pumping station, 187.8 m3
into the P2 pumping station, and 99.8 m3 of these waters into the P3 pumping station. The share of incidental waters
in the inflow to all analysed pumping stations was almost identical and accounted for about 25%. The incidental
waters caused a significant increase in the number of pumps started at the analysed pumping stations. This was
between 32 and 95 more switches per month. Depending on the pumping station, the monthly operating time of the
pumps, due to the pumping of incidental waters, has increased from 0.6 to 1.1 hours. Research has shown that
between 4.8 and 10.8 kg more CO2 may be released into the environment each year due to the energy used to pump incidental waters mixed with the wastewater.
