Opis:
It is clear that humanbeings has destroyed the nature since the last quarter of the 19 th Century with start of industrial revaluation .In the beginning of the 21st century we faced extraordinary natural disasters as well as rainfall and temperature changes, rapid ice melting in different part of the world. All these mostly have occurred under the effect of climate change and forced a paradigm shift from demand or supply oriented harsh water development to use current water resources as efficient as possible. This logical approach is getting larger and larger as the years go by. Therefore near future water management concept will shift from building new and more water supply systems to better operating existing ones. The variation of water values in time and space has increasingly motivated efforts to address water scarcity and reduce water conflicts. Hydro-economic models represent spatially distributed water resource systems, infrastructure, management options and economic values in an integrated manner. In these tools water allocations and management are either driven by the economic value of water or economically evaluated to provide policy insights and reveal opportunities for better management. A central concept is that water demands are not fixed requirements but rather functions where quantities of water use at different times have varying total and marginal economic values. The 2015 World Economic Forum Global Risks Report ranked water as the number one risk factor. All these other sources of stress on water systems will be affected and/or exacerbated by climate change. This paper reviews the vital role of Hydro-Economics concept in a sustainable water management that will implement full cost recovery policy under the effect of climate change. It also focuses on the growing problems of allocation of water resources among competitive uses

Opis:
It is "True" to say that water literally and scientifically is composed of some elements (H2O). But this is to miss the reality of what water REALLY is. It is also “True” to say that the definition very much depends on where you look from. Geopolitical changes, rapid development, water- energy- food-environment nexus, securitisation of water, climate change etc. force us to define its actual meaning especially in terms of international relationship. From this approach, the meaning of this word is gaining a wider and deeper definition not a word but a "concept". Water is a general term to describe the stuff you drink and bathe with, and it, even in the purest and other social, socio-political, economical, socio-economical, international, strategical impurities in what we call “water”. This bulk “water” will play very important role for the future of the world under the of systems, has much else than just hydrogen and oxygen. Therefore there are all sorts of minerals climate change impacts as well as increasing global inequality. This requires more attention to difference between Water term and H2O in terms of international relationship. Society of 21st Century must be aware of the higher degree of social accountability of “water” than before. A higher degree of geopolitical, social, strategical and international accountability of water is therefore need to built into the process, with a wider recognition that water cannot be described on scientific and technological terms alone as H2O. “Water” means more than H2O in this respect since the half of 20th Century. In this paper, I will examine this difference by looking more closely at the social and hydro political notion of water.

Potable water is a commodity and basic necessity of life for which metropolitan areas and adjacent areas are to pay. Water from Manila Waterworks and Sewerage System (MWSS) has also become a problem considering the low water supply coming from their sources. Because of El Nino phenomena and other problems of the water system, rationing Metro Manila was implemented. This descriptive study aimed to assess the performance and effectiveness of community water supply management in terms of the quality of water such taste, odor, color, sediments, service and cost and design water safety plan for the community. Purposive sampling was used to determine the participation of the knowledgeable homeowners of Karangalan Village in the province of Rizal. Some interesting insights of the study are: Potable water is the water delivered to the homeowners. However, there are sediments and brownish color observed in the water due to pipe corrosion. In terms of service, the performance of the water system delivered to the homeowners is acceptable based on the volume delivery, accessibility, availability, promptness, and reliability. Homeowners who use potable water are satisfied in terms of its efficiency, effectiveness, user-friendly, promptness and expandability. Water safety plan is an integral part of the whole planning process and helps improve the management of Karangalan village water supply and may be undertaken or updated at any time

Opis:
A recent study has shown increased warming in the fjords of west Spitsbergen. Their location is critical, as they are situated along the main northward pathway of Atlantic Water (AW) which is a great source of heat to the Arctic Ocean and the fjords. In the light of ongoing warming, we aim to discuss differences between the fjords under northward transformation of oceanic waters. We compared summer hydrographic conditions in two fjords located in two opposite ends of west Spistbergen: Hornsund in the south and Kongsfjorden in the north. The study is based on high resolution CTD measurements collected during Arctic cruises between 2001 and 2015. The emphasis was put not only on differences in water temperature, salinity and water masses but also the freshwater content (FWC), AW transport and heat delivery to the fjords. In general, the water in Kongsfjorden is on average 18C warmer and its salinity is higher by 0.5 compared to Hornsund. It is also characterized by two times greater transport of AW and heat delivery to the fjord. On the other hand, Hornsund reveals two times higher FWC. Both fjords undergo a gradual warming due to an increased presence of Atlantic origin waters. The ongoing warming is accompanied by an increase in variability of temperature and salinity dependent on the domination of the Sørkapp Current (SC) or the West Spitsbergen Current (WSC) on the West Spitsbergen Shelf (WSS). Nonetheless, Hornsund remains more Arctic-type fjord compared to Kongsfjorden, due to stronger blocking by SC.

Opis:
Water. In the existence and activities of each individual it is water that (un) consciously essentially defines them. Therefore, water is called the source of life, but nowadays we know it under the new concept: blue gold. The reason for such a modern understanding of the role of water lies in the increasing limitations of access to sufficient quantities, which first results in water stress – the situation where needs remain unmet, but water scarcity does not yet interfere with the foundations of the activities of societies. Water stress is thus the first form of threat to water security, especially when deficiency destroys all basic social systems that cannot function without water. The question of the role of water between them is increasingly being raised, as the operation of one system in the area of water consumption or management can mean interfering with the water potential of another system. This confronts us with the effect of the definite quantities of water, although countries with ample water resources and quantity (still) often do not understand or perceive it. Of course, this does not mean that the debate is not necessary; it is, conversely, necessary, and it is only in this way that it is possible to prevent or at least control the situation in which many countries around the world have found themselves and there is a total lack of water resources in the most existential aspects. Under these conditions, water security has become the most essential element of national security of these countries and thus a potential weak link in ensuring security.

The modern science mainly treats the biochemical basis of sequencing in bio-macromolecules and processes in chemistry and biochemistry. In these informational cybernetic principles we seek to answer the following question: Why hot water freezes faster than cold? These principles determine the freezing point of water. Determine that the hot water freezes faster than cold. What we did is the following: We translated the physical and chemical parameters from the language of water into the digital language of programmatic, cybernetic and information principles. This we did by using the adequate mathematical algorithms. By using chemical-information procedures, we calculated the numerical value for the information content of molecule of water. What we got this way is the digital picture of this molecule. These digital pictures reveal to us a whole new dimension of water. They reveal to us that the chemical process of this molecule is strictly conditioned and determined by programmatic, cybernetic and information principles.

The household charges related to the costs of water and wastewater services have already reached the level above which the principle of the price accessibility of services will be breached. This principle stems, among others, from the Treaty of Accession (it is estimated that household charges related to water and wastewater charges should not exceed three percent of the net income). That is why NIK has carried out an audit in the area.

Opis:
Water is a lifeblood aspect of human being and without water, human being is impossible in the world. From time to time, people have consumed water from many sources and the ancient civilizations also emerged from river banks to meet the need of water. In this modern industrial world, technological advancements have enabled the pipe-borne water supply in widespread manner and it is not except to Sri Lanka too. Excessive consumption of water leads to water resource scarcity and hinders the even water supply to the people. In general context, water wastage is seen as ‘the consumption of excessive water for the routing needs’. In Sri Lanka, the provision of water for drinking and irrigation on a sustainable basis is a national priority (Central bank of Sri Lanka, 2005). Despite, the pipe-borne water supply is considered as a method to supply water for people who are not access to the water, it has many contemporary impacts on water quantity’s change and consumption pattern. Thus, this study was conducted to find the pipe-borne water consuption and its wastages in Panandura urban area. The objectives of this study are ‘to evaluate the change of the quantity of pipe-borne water consumption, to find the factors for the water wastage and finding the mechanisms to reduce the water wastage and propose the proper water management plans’. This study was conducted using the primary and secondary data. As primary data, discussion, questionnaires were used and as secondary data, reports from national water supply and drainage board, Divisional Secretariat reports, books, research papers, newspaper, magazines, websites, qualitative and quantitative tools were used. Based on the analysis and using the collected data, objectives were attained as population growth, rise in income level, modern machinery utilization, urbanization are the reasons for the change of pipe-borne water consumption. And also, the main factors for the water wastages are the pattern of the water consumption of residents, water leaks and dearth of awareness among residents. To reduce the over consumption and wastage, frequently check the water leaks in households, recycle the used water, to follow the rain water harvesting methods and to conduct the awareness programmes among people regarding the water saving and wastage, were suggested as recommendations and importance of water saving and managemet also stressed in this study considering our posterity.

In recent years, the natural and economic situation in the Republic of Crimea has developed in such a way that the amount of available water resources is less than the amount of water necessary for the socio-economic development of the peninsula. This article considers one of the main water management hazards for the territory of Crimea: a lack of water. The aim of this study was to assess the water deficit and determine ways to minimize the impact of risk exposures on the population, the economy and the ecosystem as a whole. Options are provided to ensure that (1) the water economic complex supplies water to consumers in sufficient quantity and quality, and (2) the ecological status of water bodies is maintained at a high level. For example, local wastewater treatment and desalination of sea water can be used in agro-industry and the water economic complex both for individual agricultural producers and for large enterprises. The economic efficiency of the use of technologies to reduce the environmental threats of the water economic complex was assessed using technologies to increase water availability. The analysis of the quality of water resources is given, and options for improving the indicators of raw water-pipe water are proposed.

Opis:
The water of appropriate quality introduced in the water system changes its chemical properties. Depending on the chemical properties of water and pipe materials, various phenomena may occur, e.g. corrosion, and biofilm structure. The decreasing water demand in existing water systems leads to a reduction in the water flow velocity in the pipes. Accordingly, the age of the water in the system increases. It is especially visible at connections and long sections of the network. The deteriorating water quality along with the elapsing time of its stay in the pipes makes it necessary to perform appropriate measures, e.g. flushing the network. Water supply services usually perform them intuitively. The choice of flushing sites, times, or flow rates is not measured and verified. The age of the water and the efficiency of flushing can be simulated in computer programs. EPANET provides tools for such simulations. The research aimed to check the effects of flushing the network and the age of water in the pressure reduction zone. This is a case that is particularly prone to the increasing age of water. The research has shown that the network flushing sites used so far contribute to the exchange of water in the main water pipes. The simulations showed the need for the additional flush in new places, and in the tested case, the age of the water in the pipes is as much as the intervals between subsequent rinses.

Opis:
The growing population and the development of industries in all countries of the world have created a very important and complex issue for water supply to cities. Today, many parts of the world are facing the problem of water shortage and this problem cannot be easily solved. In addition to the proper use of water resources and preventing the loss of natural water, the establishment of regional water supply networks is effective in meeting the future needs of the people. A water distribution network (water supply network) is a set of interconnected pipelines used to transport and distribute water in a complex. In designing the water distribution network, factors such as the type of water distribution network, water pressure, water velocity, design flow, minimum pipe diameter, pipe material and many other factors should be considered. In this study, we have tried to design the water supply network of a part of Balikpapan city in Indonesia. The design method led to the determination of pressure values in the connection nodes, pipe diameters, flow rate and velocity in the pipes. All the existing criteria are considered in the design of the water supply network. Although this study has been implemented for a specific study area, it can be of great help to designers in designing the water supply network.

Ballast water is a significant vector for the transport and introduction of aquatic organisms, microorganisms and chemical pollutants which impacts on ecosystems worldwide. In the study, ballast water from short- and long- range vessels with treatment systems was microbiologically evaluated in spring (April 20th) and summer (July 19th) and compared with waters of the main Police Seaport in the Odra River Estuary, southern Baltic Sea. All collected samples were evaluated for their physicochemical properties by standard methods. The number of individual groups of microorganisms was determined using the indirect culture method, according to the technique of inoculation of serial dilutions of samples of the examined waters. The results showed differences in the microorganisms in analysed samples. The phylogenetic analysis of bacteria recorded from the ballast water of short-range ships in spring showed the presence of six species of the genus Bordetella, while in summer four species of the genus Clostridium. In the ballast water of long-range ships, proteolytic bacteria pre-dominated in spring and halophilic bacteria in summer. In the summer period, eight species of bacteria were recorded, of which six belonged to the genus Clostridium. The ballast water treatment processes used on ships influence the composition of bacterial communities through selective recolonisation of water, which may transform bacterial functions as an important element of the marine food web. On the other hand, the presence of pathogenic bacterial species in the tested samples indicates improvement necessity of ballast water treatment systems used on vessels.

Opis:
The hydraulic calculations of sewage networks are done ususally by the use of nomograms being the diagrams that show the relation between the main network parameters like pipe diameters, flow rates, hydraulic slopes and flow velocities. In traditional planning of sewage networks the appropriate hydraulic values are read mechanically from the the nomograms. Another way of calculation is the use of professional programs like the SWMM5 hydraulic model and genetic or heuristic optimization algorithms. In the paper still another way of realizing the hydraulic and planning calculations is presented in which the basic hydraulic rules and formulas describing the sewage networks and their functioning are used. The numerical solutions of nonlinear equations resulted from the formulas and describing the main phenomena of sewage flows are used in the paper to solve the tasks of hydraulic calculation and planing of the networks.

Opis:
The aim of the study was to determine the content of minerals in bottled waters (natural mineral water and spring water) and compare the results with information declared by the manufacturers. Nineteen types of bottled natural waters available on the local market were examined with flame atomic absorption spectrometry. The results of analyses of bottled waters available on the market showed significant differences in the concentration of the minerals. These differences depended not only on type of the water but was found within one type of product. In addition, the concentrations of the cations under study differed significantly from the values declared by the manufacturers. The biggest discrepancy was detected in the concentration of magnesium ions; in this case, the actual content was incompatible with the declared by the manufacturer one in about 80% of tested samples. These results give also valuable information for consumers, which should be conscious that not every bottled water, it is alike valuable source minerals.
Celem niniejszej pracy była ocena zawartości wybranych związków mineralnych w wodach butelkowanych (naturalnych wodach mineralnych i wodach źródlanych) oraz porównanie uzyskanych wyników z wartościami deklarowanymi przez producentów. Ocenie poddano dziewiętnaście wód butelkowanych dostępnych na rynku. W badanych produktach dokonano oceny zawartości takich makroelementów, jak: wapń, magnez, sód i potas. Zawartość makroelementów w postaci jonów w badanych próbkach wód butelkowanych oznaczono techniką płomieniowej spektrometrii absorpcji atomowej. Uzyskane wyniki badań wód butelkowanych występujących na rynku wskazują na duże zróżnicowanie w zawartości takich składników mineralnych, jak: wapń, magnez, sód, potas. Zróżnicowanie to stwierdzono nie tylko pośród różnych rodzajów naturalnych wód butelkowanych, lecz również w obrębie jednego rodzaju produktów. Ponadto oznaczone zawartości poszczególnych kationów znacznie się różnią od tych deklarowanych przez producenta. Największe niezgodności stwierdzono w przypadku zawartości jonów magnezu, gdzie w około 80% badanych próbek rzeczywista zawartość tych jonów była niezgodna z deklarowaną przez producenta. Uzyskane wyniki badań dają także cenne informacje konsumentom, którzy powinni być świadomi, że nie każda woda butelkowana jest jednakowo cennym źródłem oznaczanych związków mineralnych.

Opis:
Nigeria has greater challenges when it comes to water development and management. The current water resources development and supply status is unacceptably low and needs a major transformation. With the rapid growth in population, urbanization, industrialization and competition for economic development, water resource has become vulnerable to depletion and degradation. Management of this valuable resource is determined by its acceptability and utilization in terms of quantity and quality. Due to imbalance between demand and availability, management approaches are facing various ethical dilemas. This paper therefore considers the water supply and sanitation situation in the country and the challenges facing the sector. The paper calls for institutional reforms and review of policy targets, define key elements for the development of action and investment plans as well as provide some guidelines in order to minimize duplication and maximize effectiveness. The paper also suggested strategies and viable framework/agenda for sustainable water supply and emphasizes that the machinery of water resources development and management needs an urgent overhauling with the aim of streamlining the overlapping functions of the various agencies that have operated the system up till now. More importantly, the paper suggested integrated approaches/strategies for sustainable management as well as offers relevant policy recommendations for water resources management in Nigeria.

Opis:
This work presents problems related to the water consumption in the city of Olecko situated in the north-east part of Poland in the Warmińsko-Mazurskie Province of the country, at the eastern border of the Mazurian Lake District along the trail connecting the land of the Large Mazurian Lakes with the Suwalsko-Augustowskie Lake District. Over 2011–2012 water extraction to the municipal water supply network was studied. The volume of water extracted every day was analyzed and the gathered volumes were analyzed statistically. The varying water extraction was also studied. The obtained results were presented in a graphic form. Basing on the descriptive stats and prepared diagrams certain general conclusions were drawn and the collected study figures and facts were summed up. This allowed to determine days of the highest and lowest water consumption. Also months of extreme water extraction and consumption were determined. The water extraction ranged from 1641 m3/24h to 2607 m3/24h, at an average value of 2077.4 m3/24h. Over the period under study the day of the largest water extraction and consumption was in July and the day of the lowest water extraction and consumption in December. During a week inhabitants used the highest water amount on Saturdays and the lowest on Sundays and other feast-days. Basing on the conducted measurements also the coefficient of water consumption per capita was determined. The fluctuation of this coefficient was identical as that for the water consumption. Within the period of study it ranged from 73.3 l/M 24h to 116.5 l/M 24h. The average value of the specific water consumption was 92.8 l/M 24h. For the sake of discussion the obtained results were compared with observations across the country.

Opis:
Zapewnienie społeczeństwu miasta dostępu do bieżącej wody jest bardzo ważnym zadaniem. Od czasów średniowiecza w Gdańsku starano się o to, aby mieszkańcy mieli jak najbardziej bezpośredni dostęp do wody pitnej. Pierwszy system wodociągowy doprowadzał drewnianymi rurami wodę do studni zlokalizowanych w centrum miasta. W 1868 r. uruchomiono pierwsze ujęcie wody. zlokalizowane ono było w Pręgowie, skąd rurami grawitacyjnie woda doprowadzana była w granice miasta. Ujęcie to eksploatowane jest do dzisiaj. Wraz z rozwojem miasta i wzrostem ludności zamieszkującej Gdańsk, powstawały kolejne ujęcia wody. Gdański system wodociągowy kształtowano w taki sposób, aby ujęcia dostarczały wodę do miejskiej magi-strali, skąd rozprowadzana była w poszczególne części miasta. Obecnie gdańskie wodociągi korzystają z dziesięciu ujęć wody. Wśród nich jest jedno ujęcie drenażowe (Pręgowo), jedno ujęcie powierzchniowe (Straszyn) oraz osiem ujęć głębinowych. Woda dostarczana mieszkańcom Gdańska jest bada przez akredytowane laboratorium przez cały cykl produkcji oraz w trakcie dystrybucji w sieci wodociągowej, a jej jakość spełnia wszystkie wymagania zawarte w Rozporządzeniu Ministra Zdrowia z 1 3 listopada 2015 roku w sprawie jakości wody przeznaczonej do spożycia przez ludzi.
Assurance of the access to the running water for the city’s community is a very important task. From the Middle Ages in Gdansk it was aimed to give the residents the biggest possible direct access to drinking water. The first water supply system brought water to the wells in the city center with the use of wooden pipes. In 1868 the first water intake was activated. It was located in Pręgowo where again, with the use of pipes, water was gravitationally brought to the city’s borders. This treatment is being utilized until today. With the development of the city and increase of the Gdańsk population, new water intakes were being created. Gdansk water supply system wasshaped in the way which was supposed to provide water for the city main line, where it was distributed to various parts of the city. Currently Gdansk waterworks use ten water intakes. Among them there is one drainage intake (Pręgowo), one shot surface intake (Straszyn) and eight deep-water intakes. Water given to the residents of Gdansk is tested by an accredited laboratory through the entire production cycle and during the distribution of the water in the supply system. Its quality meets all the requirements of the Regulation of the Minister of Health of 13 November 2015 due to the case of water quality intended for human consumption.

Opis:
Water quality of seasonal water rivers is on a quick decline due to various human activities arising as a result of urbanization and population growth. This study assessed the water quality of the Khassa-Chai river in Kirkuk during two seasons: winter and summer (wet and dry). Thirty-seven water samples were collected from eight monitoring observation points along the Khassa-Chai river during October 2019 and March 2020. Water samples were analyzed for various parameters such as temperature, pH, electrical conductivity (EC), turbidity, total suspended solids (TSS), total dissolved solids (TDS), color, and dissolved oxygen (DO). These physicochemical parameters were analyzed using standards methods demonstrated by the American Public Health Association (APHA). To determine the significant difference, all the results obtained were statistically analyzed. In most results, higher concentrations are out of the indicated permissible limits of the World Health Organization (WHO). It can be concluded that the most domestic wastewater effluents are discharged into the river, such as sewage coming from nearby houses and restaurants in addition to the solid waste produced from close commercial stores. To reduce the negative impact on water and human health, pollution sources need to be properly managed. The paper calls for further research to figure out the ability of the Khassa-Chai river to make the use of city water in improving the environment.

Adept of metamorphosis, Marguerite Yourcenar repeatedly uses in her essays the image of water, fluid elements related to the idea of transformation and rebirth; sea, ocean, artificial fountain – water takes various aspects and forms; from motif in the analyzed paintings to the biological functions it exercises, water crosses the yourcenarian essays. Established in the United States of America after the Second World War, did the writer study the ecology lesson testified by her texts about water? Or do these writings rather go beyond the concrete and circumstantial level of existence to talk about a global philosophy of life, as it seems to acknowledge the title of her trilogy: As the Water That Flows?

One of the most common symbols used in literature, water, which is both a source of life and a rich symbol of meaning, is a theme that has transformed into a real instrument of aesthetic research over the last centuries. In this article, we show how the Francophone woman writer, Marie Gevers, uses the symbol of water in Madame Orpha. We also identify some of the functions that this element has in her autobiographical text and we analyze the way in which the reveries on water are reconstituted in order to give a coherent and a meaningful writing.

Opis:
Problems of water supply to seaside/resort localities are considered in the paper. The main task is to supply water of proper quality and amount at seasonal fluctuations in the demand. The paper focuses on the operation of water supply systems in the following localities of Central Pomerania: Mielno, Unieście, Mielenko, Sarbinowo, and Chłopy. They are main summer resorts of the region with typical fluctuation in population during the annual cycles affecting the amount of water supply. The atmospheric conditions, mainly temperature, generally affect the magnitude of water demand. The water-pipe system under consideration forms a very interesting technical solution for supplying both administration-industrial agglomeration, that is the municipal system, and localities lying in the seaside strip characteristic. The water intake is located in Mostowo which lies 19 km away from the main city centre of Koszalin.

Opis:
W pracy określono wpływ wód kopalnianych na jakość Potoku Goławieckiego (woj. śląskie), który jest odbiornikiem wód dołowych kopalni "Ziemowit". Badaniami objęto około 900 m odcinek biegu potoku znajdujący się poniżej zrzutu wód dołowych z osadnika ziemnego. W okresie od czerwca do grudnia 2002 r przeprowadzono 7 poborów próbek wody, w których na miejscu oznaczono temperaturę, tlen rozpuszczony, pH i mętność, natomiast w laboratorium -zawartość zawiesin, jonów siarczanowych, chlorkowych i substancji rozpuszczonych. Ocena jakości wody z Potoku Goławieckiego wykazała, iż rzeka znajduje się pod silnym wpływem wód dołowych. Duża mętność wody oraz ponadnormatywna zawartość zawiesin, chlorków i siarczanów klasyfikują wody odbiornika do V klasy czystości. Wykazano, że znaczna ilość zasolonych wód dołowych, w stosunku do średniego niskiego przepływu w odbiorniku tych wód, nie pozwala na utrzymanie dopuszczalnej zawartości chlorków i siarczanów w wodzie z Potoku Gołowieckiego. Przeprowadzone badania wykazały, że charakter hydrochemiczny Potoku Goławieckiego jest współkształtowany przez zrzuty wód kopalnianych, które przyczyniają się do zakłócenia jego naturalnego reżimu wodnego.
The investigations covered an approximately 900-meter length of the recipient downstream from the points of drainage water discharge from a settling pond. Samples were collected seven times between June and December 2002. Temperature, pH and turbidity were measured in situ; the concentrations of suspended solids, sulfate ions, chloride ions and total dissolved substances being determined under laboratory conditions. The findings produced by the study can be itemized as follows. (1) The mine water discharge strongly impacts upon the recipient. (2) Owing to a high turbidity level, as well as to the excessive concentrations of suspended solids, chlorides and sulfates, the Potok Golawiecki has been classified as a watercourse of Class V purity. (3) The large amount of the high-salinity waters received by the Potok Golawiecki, compared to their mean low flow in the recipient, does not allow the concentrations of chlorides and sulfates to be kept within the admissible levels. (4) The discharge of drainage water is a major contributor to the hydrochemistry of the recipient stream, thus disturbing its natural regime.

The paper assesses the volume and type of water consumption in Poznań using a water footprint indicator (WFTP) consisting of such components as green, blue and grey water consumption. Average rainfall over many years, water retention within the city, pollution indicators found in sewage and the amount of sewage treated from the city area were assessed. The water footprint obtained for Poznań was compared with the values of indicators for Wrocław. The presented analysis of the results of WFTP calculations should constitute the basis for assessing direct and indirect water consumption by consumers and producers of Poznań and serve better water management and maintenance in the urban area.
