The balanced model of the sustainable water consumption in a public sector in Ukraine

Abstract

Water quantity and quality are important aspects of water management concerning to the
pollution control as economic and environmental safety of any countries, Due to intensive
exploitation and inadequate pollution control Ukraine faces with degradation of natural water
resources. The Kharkiv region is an industrially developed region of Ukraine with high
population density and water resources scarcity, The disproportion in economical and water
resource potentials of the region and significant anthropogenic loadings on the water sources
lead to depletion and pollution of ones, and, as a consequence, to the water deficiency,
Dwelling sector and office buildings are one of the most powerful water consumers on
urbanized territories, Every day the big Ukrainian city, like Kharkiv, consumes no less than
200 million of cub,m water per year and 80 % of that for households water supplying, The
powerful water consumption leads to the degradation of water resource, especially, in the big
cities with water scarcity,
The aim of the work is to find a new optimal level of water resource consumption for
households and office buildings on urbanized territory to base on environmental, economic
and social aspects of water use, An environmental engineering modelling, risk assessment and
economic methods of analysis have been used for the research work,
The balanced model of quality of water environment and public water demand were
developed by real data, The regression parameters were determined for such indicators of
water quality as suspended solids, mineralization, ammonium, nitrites, chlorides,
Using the model it is possible to analyze environmental impacts of municipal water
consumption and find the optimal level of public water supply,
Also the environmental, economic and social criteria of water saving were developed,
