During long-term operation of metallic water supply networks, a deposit layer forms on the inner pipeline walls and progressively increases in thickness, which adversely affects the key performance parameters of the system. Objective: to improve the methodology for rapid automated estimation of the hydraulic potential characteristics of aging water pipelines with different values of their operational efficiency coefficient. To develop software to accelerate these computational procedures. Research Methods: the software was developed using computational relationships adopted in standard hydraulic design practice. Results: drawing on a particular case study, an improved methodology for the automated hydraulic analysis of pipes of a specified diameter has been introduced. This methodology provides a comprehensive profile of the hydraulic and energy characteristics of an aging water main, with the analysis linked directly to the thickness of internal scale and sediment layers identified through X-ray inspection. Practical significance: software has been developed to determine the operational parameters of water-supply pipelines. This software accounts for variations in the thickness of deposits formed on the pipe inner surface, enabling a more accurate prediction of remaining service life and supporting timely replacement planning. An updated method is proposed for hydraulic calculations of deteriorated metal pipeline networks with internal deposits using the automated GRIT software, whose name refers to the Hydraulic Calculation of Deteriorated Pipelines (Gidravlicheskiy Raschet Iznoshennykh Truboprovodov).
