The results of research on the patterns of changes in the costs of construction of transport facilities of wastewater disposal systems

To substantiate optimal solutions in the design of wastewater disposal systems for military infrastructure facilities, it is necessary to conduct an integrated assessment of the costs of various circuit solutions. Therefore, the article considers and analyzes the investment costs for the construction of transport facilities for drainage systems (networks, sewage pumping stations (CPS) and regulating reservoirs) and their dependence on physical parameters (pipe diameters and their depth of laying, capacity of the CPS, volume of regulating reservoirs). It is established that the cost of building drainage networks can be estimated as a function of two arguments: the diameter of the pipe and its depth of laying. At the same time, the cost of building sewage pumping stations and reservoirs depends, respectively, only on hydraulic capacity and volume.
