The authors consider particular methods, technologies and organizational aspects that may be implemented in the construction and renovation of pipelines using polythene materials instead of metals due to their economic and practical efficiency. It is noteworthy that the corrosion problem of steel pipelines is the phenomenon of metal destruction that reduces the throughput of pipelines and facilitates obstructions, juncture cleavages and water leaks as a result of reduction of service lives of pipelines. The authors analyzed the efficiency of polythene pipes from the viewpoint of hydraulic processes and the economic expediency; the authors identified that the polythene pipe’s throughput is 3 times as much as the one of steel pipes. Also, the authors determined the economic efficiency of polythene pipes: USD 0.5 million per 1 kilometer of pipeline.The authors take account of the technology-related aspect, as the water pipeline construction and reconstruction processes are limited by dense urban environments or due to the absence of overhaul factories in the close proximity to pipelines. Therefore, the results of the analysis evidence the efficiency of application of polythene in construction and reconstruction of pipeline engineering systems. It is highly resistant to abrasion and corrosion; it boosts the water flow velocity due to the low rough-ness of the internal surface; its service life is long enough, and its transportation is problem-free.

Megacities like the most massive manifestation of urban settlements, will keep on growing due to the socio-environmental reasons. And the problems of house, industrial and socio-cultural construction will grow under the conditions of vacant land limit. The approaches to the building development of new territories and previously used ones are significantly different. That requires a modification of methodological approaches and the development of new principles of evaluation. In the current situation of understanding of the biogenic processes significance, new territories can be developed in environmentfriendly way. In respect of the previously built-up or polluted areas, the evaluation of the changes in anthropogenic ecosystem should be made.In general, urbanized landscapes are growing, but the territories suitable for urban development do not grow. That dramatically raises the price for land, particularly for the previously undeveloped land. At the same time, the value of previously used for agricultural purposes land within the city or within industrial zones also increases. For any landscape, used or not, should be regarded as non-renewable.The development of technologically polluted areas require significant economic investments. As a result, the development of optimal methods of the area valuation for further investment and construction is important. As commonly cited, soil and land have no value as such, which should be compared with the income. The market price of one square meter finally gives us the value of undeveloped land, and its location, status, and the possibility of further use is of crucial significance. Investors evaluate real estate not only by the location, but also by material, income and profitability. Systematic investigation of these criteria allows us to see the weaknesses and advantages of the land. The cost of real estate can change quickly in case of changes in its pricing factors. A good example is construction of a highway in the neighborhood: positive for industrial construction, negatively for living. Therefore, such signs should be permanently recorded and evaluated.
