In drainage systems, it is often necessary to raise polluted rain and melt water to a low height. For example, pumping wastewater from one gravity collector to another, raising wastewater by several meters in order to reduce the deepening of the collecting sewer collector and, as a result, reduce capital costs for its construction. In such places, it may be more economically feasible to reduce such deepening. The novelty of the study is that the development of a drain can be fulfilled only if the filling of the throughput of the collectors is sufficiently ensured. The study shows that the possibilities of expanding collectors can be achieved based on compensation for energy consumption. The study outlined the necessity of allocating the device of a high-pressure pumping station with the subsequent laying of a pressure sewage collector to a common collector, or to the main sewer network, which in turn supplies rain and melt water to the main collector. The practical significance of the study is the widespread introduction of intermediate pumps of low pressure in sewerage networks is constrained by the lack of a sufficient range of reliable and economical low pressure pumps for contaminated liquids.
