Строительство сетей водоснабжения и водоотведения г. Новокузнецка осуществлялось в 19501970 годах при бурном развитии промышленного города. Сегодня ООО Водоканал является основным предприятием в Новокузнецке, предоставляющим коммунальные услуги холодного водоснабжения и водоотведения населению и предприятиям города. В 1990-е годы состояние сетей и экономическая ситуация в стране требовали поиска новых эффективных технологий строительства и ремонта с минимальными затратами времени, ресурсов и финансовых средств для максимально эффективного выполнения работ. На сегодняшний день настрой предприятия на поиск технически новых и в то же время экономически эффективных методов ремонта сетей водоснабжения и водоотведения позволяет обеспечить потребителей качественной питьевой водой как одного из факторов санитарно-эпидемиологического благополучия, повышения эффективности, надежности и качества работы систем и сооружений питьевого водоснабжения и водоотведения города.The construction of water distribution and sewer networks in Novokuznetsk was carried out in 19501970 with the rapid development of the industrial city. Today Vodokanal LLC is the main provider of cold water supply and wastewater disposal services to the population and industries in Novokuznetsk. In the 1990s, the conditions of the networks and the economic situation in the country required the search for advanced time-effective construction and repair technologies at minimum use of resources and finance for the most efficient performance of work. Today, the attitude of the enterprise for search for technically new, while also cost-effective, methods of repairing water distribution and sewer networks allow providing consumers with high-quality drinking water as one of the factors of sanitary and epidemiological well-being, improving the efficiency, reliability and quality of operations of the municipal drinking water supply and wastewater disposal facilities.

Рассмотрены вопросы надежности трубопроводов сетей водоснабжения и водоотведения городов и поселений России. Приведены соображения (в порядке дискуссии) о необходимости разработки и принятия Технического регламента о безопасности сетей водоснабжения и водоотведения централизованных систем водоснабжения и водоотведения. Технический регламент установит требования к сетям водоснабжения и водоотведения, обязательные для применения и исполнения на территории РФ. Отмечено, что в водной отрасли России в настоящее время отсутствует единая система, выработанная на основе практики применения обязательных требований к трубной продукции, используемой в сетях водоснабжения и водоотведения, и обязательной сертификации (декларирования). Предлагается область применения такого Технического регламента – сети централизованных систем холодного водоснабжения и водоотведения (канализации) на всех этапах их жизненного цикла, а также материалы и изделия, трубы, арматура, колодцы и связанные с ними процессы проектирования, строительства, эксплуатации, технического обслуживания, текущего и капитального ремонта, консервации и ликвидации сетей водоснабжения и водоотведения (канализации). The issues of reliability of pipelines of water and sewer networks of Russian cities and settlements are considered. Considerations (by way of discussion) on the need for the development and adoption of Technical Regulations on the safety of water and sewer networks of public water supply and wastewater disposal systems are presented. The Technical Regulations will establish the requirements to water and sewer networks that will be mandatory for use and compliance on the territory of the Russian Federation. It is noted that the water industry in Russia is currently lacking a uniform system developed on the basis of the practice of applying mandatory requirements to pipe products used in water and sewer networks and their mandatory certification. The scope of application of such Technical Regulations is proposed, i. e. networks of public systems of cold water supply and wastewater disposal (sewerage) at all stages of their life cycle, as well as materials and articles, pipes, fittings, manholes and related processes of design, construction, operation, maintenance, current repairs and overhaul works, conservation and abandonment of water supply and sewer networks.

Summary. Introduction: Drinking water is one of the most important environmental factors sustaining life and determining human health. The goal of the Russian Federal Clean Water Project is to improve drinking water quality through upgrading of water treatment and supply systems using advanced technologies, including those developed by the military-industrial complex. The most informative and reliable sources of information for assessing drinking water quality are the results of systematic laboratory testing obtained within the framework of socio-hygienic monitoring (SGM) and production control carried out by water supply organizations. The objective of our study was to formulate approaches to organizing quality monitoring programs for centralized cold water supply systems. Materials and methods: We reviewed programs and results of drinking water quality laboratory tests performed by Rospotrebnadzor bodies and institutions within the framework of SGM in 2017–2018. Results: We established that drinking water quality monitoring in the constituent entities of the Russian Federation differs significantly in the number of monitoring points (566 in the Krasnoyarsk Krai vs 10 in Sevastopol) and measured indicators, especially sanitary and chemical ones (53 inorganic and organic substances in the Kemerovo Region vs one indicator in the Amur Region). Discussion: For a more complete and objective assessment of drinking water quality in centralized cold water supply systems, monitoring points should be organized at all stages of water supply with account for the coverage of the maximum number of people supplied with water from a particular network. Thus, the number of points in the distribution network should depend, inter alia, on the size of population served. In urban settlements with up to 10,000 inhabitants, for example, at least 4 points should be organized while in the cities with more than 3,000,000 inhabitants at least 80 points are necessary. We developed minimum mandatory lists of indicators and approaches to selecting priority indices to be monitored at all stages of drinking water supply.

Quality changes of drinking water in the water supply network (case study from Lithuania) The purpose of this research was to examine water quality changes by distributing in to the water supply network. Water samples were collected from Varena town (Lithuania) drinking water distribution system fed by groundwater from well field. Parameters related to undesirable increasing of nitrites and nitrates concentrations have been measured considering these samples: pH, conductivity, concentration of total iron, manganese, ammonium, nitrates and nitrites. Results showed that groundwater from well field were extremely susceptible to favor bacterial growth in the pipelines. The occurrence of nitrites and nitrates in drinking water samples correlated positively with the lengths of old iron pipelines and negatively with the content of newly laid pipelines. The obtained results also showed that the potential nitrates increasing induced by the distribution of treated water could be reduced if: nitrates levels were below detection limits at the outlet of the water treatment plant; biological ammonium removal treatment implementation should reduce the levels of the nitrates and nitrites of the treated supplied water. Although the nitrates concentration increase in drinking water distribution systems, the issues with nitrites accumulation are rare in Lithuania. However, such processes still need to be proved in more extensive investigation, but these research results could be applied as a basic scenario.

This document proposes a methodology for assessing the quality of water distribution service in the context of intermittent supply, based on a comparison of joint results from literature reviews and feedback from drinking water operators who had managed these networks, with standards for defining the quality of drinking water service. The paper begins by reviewing and proposing an analysis of the definition and characterization of intermittent water supply (IWS), highlighting some important findings. The diversity of approaches used to address the issue and the difficulty of defining a precise and detailed history of water supply in the affected systems broadens the spectrum of intermittency characterization and the problems it raises. The underlined results are then used to structure an evaluation framework for the water service and to develop improvement paths defined in the intermittent networks. The resulting framework highlights the means available to water stakeholders to assess their operational and management performance in achieving the improvement objectives defined by the environmental and socio-economic contexts in which the network operates. Practical examples of intermittent system management are collected from water system operators and presented for illustration purposes (Jeddah, Algiers, Port-au-Prince, Amman, Cartagena, Barranquilla, Mexico, Cancun, Saltillo, Mumbai, Delhi, Coimbatore …).

Economic and population growth in Mexico City (CDMX) is the main cause of an increase in water demand against a naturally limited endowment, which increases the gap between water demand and supply. In a water scarcity environment, households are facing pressure to maintain their involvement in the city’s only operating body, the Water System of Mexico City (SACMEX) total supply. The objective of this work is to measure the inequality in the distribution of drinking water and water subsidies between households connected to the public network of CDMX in order to generate objective indicators of the phenomenon. Having such information provides a baseline scenario of the problem and allows for the delineation of a policy covering the minimum levels of well-being in the supply of drinking water that is appropriate for the most important city in the country. The method consists of measuring inequality through continuous variables estimating the Lorenz curve, the Gini coefficient, the targeting coefficient and elasticity in water consumption and in water subsidies among households in CDMX. Data comes from a household survey carried out in 2011, Consumption Habits, Service and Quality of Water by Household in Mexico City (EHCSCA). Results show that drinking water and subsidies present a regressive distribution, benefit high-income households and, to a lesser degree, the poorest households in the city and highlight the urgency and importance for SACMEX to redefine its policy on water distribution, fees and subsidies. The present study’s scope can contribute to the monitoring of the distribution of drinking water and of subsidies among household groups. The study justifies that the indicators employed in this work can be used and are recommended as a valuable tool in water management, especially in a dynamic environment.

Water Project

Every country’s influence and livelihood is centered on that country’s water source. Therefore, many studies are being conducted worldwide to improve and sustain water resources. In this research paper, we have selected and researched the water scheme for groundwater recharge and drinking water supply of drought prone areas. The water project is aimed at connecting the drought prone areas of the three districts of Tamil Nadu to filling up the ponds in their respective villages and raising the ground water level and meeting the drinking water requirement. We have chosen a multi-criteria decision method to select the best alternative in a complex situation. When reviewing the implementation of this water project, many experts and people who will benefit from this project may have some hesitation and ambiguity in their suggestion on choosing the best water distribution system.We believe that the benefits of this project can be fully availed of if we choose a water distribution system. Our contribution in this article is to choose the best water distribution system for this project by use of our proposed multi-criteria decision making (MCDM) methods, hesitant fuzzy standard deviation with multi-objective optimization method by ratio analysis (HFSDV-MOORA), hesitant fuzzy standard deviation with technique, for order preference by similarity to an ideal solution (HFSDV-TOPSIS) and hesitant fuzzy standard deviation with VIsekriterijumsko Kompromisno Rangiranje (HFSDV-VIKOR), which will provide the best solution for improving the water resource for the drought-prone areas of three districts. Finally, we have identified and compared the correlation coefficient between proposed methods. As a result of the study, it has been found that the best water supply system is closed concrete pipes laid along agricultural land through the rural areas.
