The aim of the article is to determine the impact of the structural solution of piling partitions of an innovative retention canals on the hydraulic conditions of its functioning in a specific sewerage network. Three types and different variants for controlling the operation of piling partitions were analyzed. The research shows that the construction of piling partitions has a significant impact on the achieved reduction rate of sewage outflow from the analyzed sewerage network. In addition, the construction of piling partitions also determines the volume of sewage that can be restored in sewer networks. The most tangible effects were observed when the partitions were made in the system (1), i.e. they had drainage holes of an adjustable geometry. In this example, a reduction in the peak sewage outflow from the sewage network to a value of only 531.36 dm3/s was observed, which corresponds to the value of the wastewater reduction coefficient β = 0.34. What is worth emphasizing, with the other methods of functioning of piling partitions, small values of the wastewater reduction coefficient were also obtained successively for the system (2) β = 0.35, while for the system (3) β = 0.43. On the basis of the tests carried out, it was also found that the authoritative time for dimensioning the sewerage network equipped with piling partitions always takes values higher than the reliable time for dimensioning a traditional sewerage network
