This article focusses on the review of formulas for the hydraulic calculation of gravity drainage networks with internal deposits. In the existing practice of calculating gravity flow networks, there are methods of hydraulic calculation only for new pipes. At the same time, on the walls of pipelines, under certain conditions, layers of deposits with different structure can be formed, which affect the values of hydraulic characteristics of the system. The aim of the work is to identify the calculation dependencies for pipelines with deposits in gravity drainage networks. Hypotheses and formulas for the pipeline calculation, as well as the existing provisions of regulatory documentation in the field of wastewater disposal are used. Calculation dependences for pipelines with deposits are revealed, and the concept of reduced diameter of pipes is introduced. The directions of further study of influence of thickness of a layer of deposits in a flume part of pipes on values of their hydraulic characteristics and necessity of development of tables for hydraulic calculation of pipes of gravity drainage networks with internal deposits are allocated.
