Integrated Water Management

Freshwater water resources are not inexhaustible [1]. In recent decades, more and more facts point to this statement from the European Charter for Water. Uncontrolled drinking water interventions, losses in water supply and climate change indicate the problem of sufficient quantities of drinking water [2]. Looking at this problem, it is hard to believe that new quantities of drinking water can be produced. The model of integrated water management has been increasingly used in recent years. The application of new technologies in water supply creates conditions for the controlled management of water intakes and losses in water supply. Each water sapply system needs to develop its own model for integrated water management.

The Cost

Abstract The deteriorative processes occurring in the environment, the growth of population, the water demand of industry and agriculture, point out day after day the increasing role of water management. The economical use of drinking-water consumption as well as the cost reduction is becoming more and more important. In this research, the measure of a water supplier of Győr was examined in terms of implementing the purposes above.

Sustainable Water Supply

One of the powerful factors behind the transformation of the components of the institutional environment that has evolved dynamically in recent decades is considered to be the environmental constraint, the main reason for which is the exacerbation of global environmental challenges and changes in the world-view of the modern world. In this regard, the study identifies and analyzes the patterns of transformation of conceptual approaches to the formation of a sustainable water supply system under environmental constraints. It is proved that one of the determining external factors that cause such transformation is the increase of environmental awareness of the population at the local, national and world levels. The system of methods of sustainable water supply in the conditions of ecological restrictions is proposed, which provides for complex scientifically grounded application of modern infrastructural, institutional and ecosystem mechanisms of water policy implementation and institutionalization of a number of strategic directions and processes of development of integrated water resources management of Ukraine. It is established that in the field of institutional support for sustainable water use, the evolution of conceptual approaches under the influence of «ecological» philosophy will determine, first and foremost, the improvement of the regulatory system of streamlining relations, its focus on optimizing the use of water resources, their conservation and reproduction. It covers all the main characteristics of the institutional environment, the system of rules and norms of behavior of economic relations, changes in the set of incentives for entrepreneurial activity and in the sphere of coordination of economic, financial and regulatory activities and state planning. Therefore, the strategic directions of transformation of the current water management system in order to ensure their expanded reproduction is the institutionalization of new rules and standards for the economic development of water resources, in particular the specification of ownership rights for water resources and the spread of modern forms of public-private partnership in the field of water use. This will increase the level of investment support for the reproduction of water resources and expand the available financial base for the modernization of water management infrastructure.

The presence of some chemical compounds at higher levels than maximum permissible concentrations (MPC) in the drinking water, suggests of water resources pollution. In this paper the following elements were analyzed: total arsenic, cadmium, lead, cooper and zinc. Twelve samples of water from the water supply system from the city of Skopje were examined during one year from three different springs. Also, ten samples of bottled water from three producers from the Macedonian market were tested.The determined average mass concentrations of total As, Cd(II), Pb(II), Cu(II) and Zn(II) in the analyzed water samples from the water supply system are 1.35 μg/l, 0.06 μg/l, 0.6 μg/l, 0.9 μg/l and 1,12 μg/l, respectively, and for the tested bottled water, the mean values ranges from 0.56 - 0.83 μg total As / l, 0.053 - 0.056 μg Cd(II)/l, 0.51 - 0.54 μg Pb(II)/l , 0.6 - 0.87 μg Cu(II)/l and 0.68 - 0.8 μg Zn(II)/l water.The following instrumental analytical methods and techniques were used for the analysis of the tested samples of drinking water: flame atomic absorption spectroscopy (AAS), atomic absorption spectroscopy with hydride cеll, electrothermal atomic absorption spectroscopy.The obtained results are shown in tables and graphic form. According to the obtained results a comparative analysis was carried out indicate that it is a water of good quality that can be used in different branches of the process industry.The obtained results in this paper do not exceed the values of the MPC of the Republic of Macedonia prescribed by the legal regulations for the drinking water, which confirm the health safety of the drinking water from the water supply system in the city of Skopje and the packed waters from the Macedonian market in relation to the tested elements.

Работа посвящена системному анализу данных показателей исходной воды при производстве питьевой воды в системе центрального водоснабжения крупного населенного пункта. На сегодняшний день на фоне увеличивающегося негативного антропогенного воздействия на окружающую среду наблюдается ухудшение состояния многих источников питьевого водоснабжения в широком спектре показателей, в частности, таких как органолептические свойства воды. Как следствие, возникает проблема и для питьевой воды. В работе приводится процесс подготовки данных о параметрах исходной воды, забираемой из водохранилища, которые ежемесячно (с 2002 по 2014 год) учитывались на предприятии при дезодорации воды. Приведенные параметры оказывают существенное влияние на органолептические свойства конечной воды. Подготовка данных для анализа проводится методом главных компонент К. Пирсона. Данные, полученные в пространстве R9, переводятся в пространство меньшей размерности R3. Понижение размерности позволяет снизить автокорреляцию между компонентами. Отбор компонент в пространство R3 проводится по правилу Парето. В пространстве R3 методом сферической кластеризации данных «Форель» с постоянным радиусом группировки проводится кластеризация. Приводится пошаговое визуальное представление алгоритма кластеризации в пространстве R3. В работе показано, что в данных показателях качества исходной воды имеются кластеры. Проводится корреляционно-регрессионный анализ данных, представленных в главных компонентах. Строятся регрессионные зависимости показателей органолептических свойств от главных компонент из пространства R3.
