Abstract The article is devoted to the analysis of the operation and operation of membrane elements of reverse osmosis plants in the conditions of the Rostov region. The reasons for the decrease in the service life of membrane elements are considered on the basis of studies of membranes operating in various regions of the Rostov region.

Introduction. A review of the judicial practice of securing land use rights on the territory of sanitary protection zones (SPZ) of sources of centralized household drinking water supply of the population, a comparative analysis of Russian and foreign approaches to the legal regulation of sanitary protection of sources of centralized household drinking water supply (starting now - SPZ). The computational methods for assessing the spread of pollutants and determining the size of the boundaries of the 2 nd zone of the WSS for water sources, analysis of the degree of protection of aquifers of drinking water supply sources, which can become an alternative to expensive measures to prohibit economic activities in the territory of the SPZ, have been updated. The data on the water pollution of the sources of the centralized drinking water supply of the population of the Russian Federation, the Moscow River, on the effect of surface runoff polluted with persistent organic substances on the sanitary state of surface waters are presented. Material and methods. Methods of the survey, comparative analysis were applied to assess the legal regulation of sanitary protection of sources of centralized drinking water supply to the population in urbanized areas, hygienic assessment of water pollution, correlation and regression analysis. Results. The data of field studies of surface water bodies and groundwater in the Russian Federation indicate the low efficiency of wastewater treatment to ensure water quality safety in the sources of centralized drinking water supply to the population. On the one hand, the low efficiency of groundwater protection and the ability to protect groundwater due to natural conditions are shown. Judicial practice confirms the need to establish the security of a water supply source from wastewater when justifying health hazards and violations of current regulations. Conclusion. The analysis of the legal regulation of the protection of sources of centralized economic water supply to the population and treatment, wastewater disposal showed that the issues of the legal status of the territory of the SPZ of water sources are not developed. The need to standardize approaches to the organization of SPZ and the methods used to ensure the protection of sources of centralized drinking water supply to the population was not evaluated.

Providing everyone with safe drinking water is a moral imperative. Yet, sub-Saharan Africa seems unable to achieve “safe drinking water for all” by 2030. This sad situation calls for a closer examination of the water supply options for both rural and urban populations. Commonly, two main aspects are considered: (1) behavioural responses to available or potential water supply options, and (2) socio-economic acceptability. These aspects determine the feasibility and the affordability of bringing safe drinking water as a basic good and human right to everyone. There is a broad consensus that achieving the UN Sustainable Development Goal 6.1 is mostly a financial issue, especially in low-income settings. This communication challenges this view as water is available everywhere and affordable treatment options are well-known. It considers the decentralized water supply model as a reference or standard approach in low-income settings rather than as an alternative. Here, the medium-sized city of Bangangté in the western region of Cameroon is used to demonstrate that universal safe drinking water will soon be possible. In fact, during the colonial period, the residences of the elite and the main institutions, including the administrative quarter, churches, and hospital, have been supplied with clean water from various local sources. All that is needed is to consider everyone as important or accept safe drinking water as human right. First, we present a historical background on water supply in the colonial period up to 1980. Second, the drinking water supply systems and water demand driven by population growth are discussed. Finally, a hybrid model for the achieving of universal access to clean drinking water, and preconditions for its successful implementation, are presented. Overall, this communication calls for a shift from safe drinking water supply approaches dominated by centralized systems, and presents a transferable hybrid model to achieve universal clean drinking water.

Abstract The quantity of management systems standards (MSSs) is increasing every year. Standards are significantly associated with common requirements and differences for many providers of services as well as for manufactures. The drinking water supply management system is certainly one of the important services. The aim of this article is to introduce a basic application of management system (MS) using visual management. The standard applied in a model, defined as a complex solitaire or “singlet”, is the Water Efficiency Management Systems (WEMS) standard. Visualised model is built by creating clusters using a software program designated for Small World Networks. This phase is preceded by the compilation of Excel spreadsheets, where requirements are divided into common and specific ones. The resulting cluster of selected areas includes the context of organizations that provide services, considering the common and specific requirements of interesting parties, managing their leadership, planning, support, operation, performance evaluation and improvement. It could be very useful to extend the cluster by another standard depending on the needs of the drinking water supplier and the transport piping systems at the site. This approach to management systems intensively clarifies managerial decision-making processes related to the implementation of the WEMS.

Abstract Drinking water is an aspect of development that has an essential function in supporting community welfare because it relates to health, social and economic conditions. Therefore, the urban water system needs good planning, design, and operational infrastructure. This paper aims to identify actors and their roles in the drinking water supply system in Indonesia. Analysis was carried out on laws and regulations related to drinking water through content analysis. The results showed that government capacity in building and administering drinking water supply system was still lacking. In addition, the government shared the responsibilities to enterprises, both owned by the government and by private institutions. Finally, it is necessary to equip and expand laws and regulations to provide drinking water distribution. The critical implication to stop the massive exploitation of groundwater for consumption includes the improvement of drinking water reliability by synergizing and integrating all attempts by various actors in providing drinking water.
