Adaptation of International Approaches to Creating a Statistical Indicators System for the Water Management Analysis at the City Level

The article aims at substantiating the theoretical and methodological foundations for creating a unified statistical indicators system and statistical analysis of the water resources management at the city level. The advantages of using standardized indicators in the field of sanitation and water supply at the city level are identified and characterized in accordance with ISO 37120: 2014 «Sustainable cities and communities – indicators of urban services and quality of life». Both the main and auxiliary indicators of urban services and quality of life on «Water and sanitary conditions» and «Sewage» topics are systematized as for their formulas, application features and data sources. It is established that, according to the Water Risk Filter, Ukraine can be divided into four regions depending on the water risk, namely, low, moderately medium, medium, and high water risk levels. Based on these data, such cities from the Global Register of Cities developed by the World Council on City Data (WCCD) were selected: Amsterdam (Netherlands), Barcelona (Spain), Dubai (United Arab Emirates), Guadalajara (Mexico). Their indicators in the field of sanitation and water supply were analyzed. It is established that these cities are characterized by a high level of water supply and sewerage services, as well as a fairly high level of the access to high-quality sanitary and hygienic conditions. The situation with quality indicators of water management is worse. For example, advanced waste treatment is only carried out in Dubai. In Guadalajara, 21% of urban wastewater is not treated at all. It is established that in general, Dubai is the leader in the quality of water supply and sanitation services, while Guadalajara is the outsider city, showing the lowest quality levels of most of the studied indicators. The national system of indicators is suggested to be expanded by including such an indicator as «Average annual duration of water supply outages per 1 household»
