Annotation: The economic analysis of the current prices for the laying of pipes for external water supply networks depending on the material they made of has been undergone. The polynomials for the main pipes used for laying or replacement in the external water supply networks and the optimum price performance, in which the pipes made of different materials are the most economical have been made up. To construct the mathematical dependencies, capital costs for laying a plastic pipe diameter and type of soil have been determined by a specific list of works at which the pipes have to lay and the polyethylene pipes have been separated in dependence of the minimum long-term durability. The given technique can be used in calculation of cost estimates developed for laying plastic pipes in different kind of soils. The findings of the investigations can be used for analysis and the design techniques of optimum diameter of pipes at joint solution of problems in hydraulics and economics for laying polyethylene pipelines.
Keywords: external water supply networks, polyethylene pipes, capital costs, pipeline laying.
