Vasilenko S. Ensuring environmental safety of municipal water supply systems

Object - ecologically dangerous processes, related to the functioning and development of water-supply systems. Subject - scientific basis, methods of analysis, forms control and technical support to ensure the environmental safety of urban water supply. Purpose is improvement of the scientific fundamentals of municipal water-supply ecological safety with the reasoning and the creation of new effective methods and technical means. Methods: mathematical and computer modeling, mathematical statistics, GIS-technologies, bio-testing, system analysis. Theoretical and practical results: it is suggested to examine jointly the influence of external factors on the water-supply system and its reverse effect on environment; the complex development model for the water-supply systems is defined; methods, recommendations and technical means are developed in the part of: analysis of the state and renovation of water-supply networks, selective multilevel water intake, water quality modeling and control for water bodies, estimation of a system's power efficiency. Scientific novelty: theoretical fundamentals of the ecological safety of urban water-supply systems are developed; methodology of its study on hierarchical principle with the use of system indexes is offered; postulates, principles, determinations and general system engineering rules for water-supply safety are formulated. In water utilities are introduced: an early warning system based on automatic water toxicity control post, feasibility study for water pipelines reconstruction, selective water intake, mathematical models of water quality and hydrology, optimization of water exchange in the liquid reservoirs. Field of application - ecological safety of water utilities.
