Abstract:

The development of water supply and sewage systems in rural areas in Poland is presented. Several factors characterizing progress in their construction are analyzed. The scope of analysis covers such factors as the percentage of population using the systems, increase in the length of the water supply and sewage networks, the number of connections to the systems, mean values of water consumption and sewage production for the water supply and sewage system connections, respectively, and the per capita water consumption. The source material is the data published by the Central Statistical Office

Abstract:

The paper shows the effective way of water supply and water drainage of small communities which consists in the reuse of purified sewage for irrigation purposes. A circulating water system has been developed which has some advantages due to a more simple technological scheme, lower drinking water consumption from the source and the use of biogenic elements of sewage water.

Abstract:

To meet the needs of ecological buildings, it is necessary to improve the speed of sewage treatment. Therefore, this study analysed the impact of zinc oxide (ZnO) nanoparticles on the water supply and drainage of ecological buildings. In the experiment, zinc oxide nanoparticles were selected and the experimental environment was set up to study the treatment effect of nanoparticles on water supply and drainage wastewater. The experimental results show that: the application of zinc oxide nanoparticles in water supply and drainage can effectively remove trace elements in sewage and reduce the eut

Abstract. When designing urban water supply and sewerage systems, the substantiation of pipeline diameters and velocities of the fresh and sewage water should be carried out. The existing approaches and regulatory requirements provided in SP 31.13330.2012 consider economic factors in terms of reduced costs for the construction and operation of water supply and sewerage systems. However, according to GOST R 587885-2019, the design option should be selected on the basis of its life cycle costs (LLC).

Bangladesh, with a population of approximately 180 million, faces severe challenges in wastewater management and access to safe drinking water. The widespread use of shallow tubewells and unsealed sanitary latrines, especially in rural areas, leads to fecal contamination of groundwater, resulting in waterborne diseases and long-term health issues. Urban areas also suffer due to inadequate sewerage systems and untreated sewage discharge.

Abstract:

The article shows the most significant problems of functioning and development of the water economy of the Republic of Dagestan. The results of a comprehensive analysis of the state of the waters of the Caspian Sea are presented, which shows that the main pollutants here are coastal cities and other settlements with their sewage and other wastes of human activity. It is noted that most of the sewage water is now discharged into the sea directly, without passing through sewage treatment plants. The extremely unfavorable ecological situation in the coastal part of the sea serves as a serious det

Abstract:

To prevent the contaminated water from flowing back into the potable water supply, Particle Image Velocimetry (PIV) was employed to measure the variation of flow field and study the relation between the minimum air gap h and the water outlet diameter d concretely. The theoretical analysis and the experimental results show that the h/d is not vary linearly as required in ‘Code for Design of Building Water Supply and Sewerage’ but exponentially.

The article describes selected changes in the Water Law and the Collective Water Supply and Collective Sewage Disposal Act and their possible impact on the valuation of wastewater treatment plants. The issue of company valuation using DCF method is presented. By applying this method, several variants of assessment of the impact of changes in the law on the value of the sewage treatment plant in Głogów are proposed.

This article pinpoints the problem of no modern water supply and sewage systems in homes of ca. 22-24 million people in the Russian Federation residing in the countryside nowadays. As a statistical database, the authors use the results of the Rosstat surveys entitled "The Comprehensive monitoring of the living conditions of the population" that were conducted in 2011 and 2020. We analyze the data on cold and hot water supply systems, sewage systems and toilets in homes of households across the country in general, in rural areas and in individual houses (the private sector).

This study aimed to evaluate the nutritional status of the sunflower (Helianthus annus L.) irrigated with domestic effluents. The study was performed in a pilot sewage treatment plant, where the treatments were composed by the combination of two factors: types of water (A1 - effluent treated by UASB reactor; A2 – effluent treated with digester decant and anaerobic filtering; A3 – effluent treated with anaerobic filtering; and A4 – water supply) and irrigation depths (L1 - equal to the crop evapotranspiration (ETc) and L2 – 1.2 ETc.

Abstract:

Surface water bodies, which are sources of drinking water supply, receive a significant amount of pollution from wastewater. This negatively affects the ecological condition of water resources and poses a threat to the health and sanitary well-being of the population. The main pollutants of surface sources are: sewage of economic-fecal and industrial sewage, which contain organic pollutants, surfactants, heavy metal ions; oil products coming from industrial sites and urban areas; effluents from livestock farms and storage ponds of production waste; washing of mineral fertilizers and pesticides

Smart city in water resources area attempts are being made by establishing an integrated urban water cycle model for a stable water supply and efficient water management in the city. Accordingly, the need for simulation and integrated management of water consumption in cities is increasing. If it is possible to predict and respond in advance to consumers' water consumption, more efficient urban water resource management will be possible based on river intake. Therefore, in this study, an integrated urban water cycle model was constructed that links river intake, water purification plants, rete

The development of essential services including water and sanitation in many megacities of the economically developing countries of Asia cannot keep pace with their rapidly growing population and accompanying urban and industrial development. The inadequate water supply and poor sanitation services lead to contamination of their water supply through the input of sewage water into groundwater. This paper examines the problem of contamination of water supply in Karachi, the largest city in Pakistan with a population of over 12 million and growing at 6 percent per annum.

This literature review has been drafted to explore and emphasise the potential environmental health risks and benefits of recycling wastewater especially in areas affected by prolonged drought. With limited water resources, recycled treated sewage water can be used to augment the fresh water supply. This review will provide an understanding of the importance of water recycling and the environmental impacts recycling can have on the environment. A comparison is also provided to understand the environmental effects of untreated sewage on the environment and the potential benefits associated with
