Надежность и экологическая безопасность являются основными требованиями, предъявляемыми к системам водоснабжения и водоотведения. Трубопроводные системы – неотъемлемая часть инфраструктуры современных городов. Нарушения нормального уровня работы этих систем связаны в основном с авариями (отказами) на участках трубопроводов – наиболее функционально значимых, дорогостоящих и уязвимых элементов систем. Нарастающие темпы износа и неудовлетворительное техническое состояние значительного количества трубопроводов водоснабжения и водоотведения большинства городов и поселений России, ограничение в условиях реформирования жилищно-коммунального хозяйства России материальных ресурсов на их восстановление и обновление требуют научно обоснованного подхода к решению проблемы оценки и обеспечения их надежности. Отмечено, что до настоящего времени в отечественной практике накопление и использование статистических материалов, необходимых для определения показателей надежности элементов систем водоснабжения и водоотведения, а также планирование их восстановления организованы неудовлетворительно. Приведены методы оценки надежности трубопроводов, методика планирования их восстановления с использованием компъютерной программы, критерии выбора объектов восстановления трубопроводов и пути повышения их надежности. Reliability and environmental safety are the main requirements for water supply and wastewater disposal systems. Pipeline systems are an integral part of the infrastructure of modern cities. Malfunctions of these systems are mainly associated with failures in pipeline sections, that are the most functionally significant, expensive and vulnerable elements of the systems. The increasing rates of wear and unsatisfactory technical condition of a significant number of water pipelines and sewers in most cities and communities of Russia, the limited material resources for their rehabilitation and renovation in the context of reforming the housing services and public utilities of Russia require a scientifically based approach to solving the problem of assessing and ensuring their reliability. It is noted that up to now, in domestic practice, the accumulation and use of statistics for determining the reliability indicators of the elements of water supply and wastewater disposal systems, as well as planning their rehabilitation, have been arranged unsatisfactorily. Methods for assessing the reliability of pipelines, a methodology for planning their rehabilitation using a software application, criteria for selecting objects for pipeline renovation and ways to improve their reliability are presented.

The subject of the paper is the reliability and environmental safety of water supply and sewer pipelines of public water supply and sanitation systems. It is shown that the steadily increasing rate of deterioration of water supply and sewer networks in cities and communities in Russia, the limitations of material resources for their rehabilitation have aggravated the problem of ensuring their reliability in recent years. The paper presents the reasons for the low reliability of pipelines. It is shown that the determining criterion for the environmental safety of pipelines is reliability - one of the main quality indicators of any structure (system). The research method was a statistical estimation of the reliability indicators of water supply and sewer pipelines, and an analysis of the factors that shape their change. The paper results in suggestions for a planning strategy of the rehabilitation and renovation of pipelines and reduction of all types of water losses.

Water fittings are an integral part of the internal water supply system. The reliability of their work under operating conditions largely influence on the continuity of water supply to the population. The reliability indicators of sanitary fittings allow the services responsible for the technical condition of the indoor water supply of houses to pay priority attention to the factors that determine the uninterrupted water supply of the population and reduce the loss of drinking water. In this study, the results of indicators of operational reliability of faucets for sinks in kitchens and washbasins in toilet rooms of apartments of multi-store residential buildings in a residential neighborhood are presented. The study was performed based on the analysis of records in the logs of data on valve failures for 2016-2018. The main malfunctions are established, the random coincidence of which leads to failures. The reliability of sanitary fittings is affected not only by their structure and the characteristics of the materials, as well as by the exploitation conditions. The probability of failure-free operation of sanitary fittings in exploitation conditions for a time not exceeding the duration of the reduction of water supply to consumers in residential buildings is the basic parameter of its reliability.

The People

The Ruhr, with an average flow of 80.5 m3/s at its mouth, is a comparatively small tributary to the Rhine River that has to perform an important task: to secure the water supply of more than 5 million people and of the industry in the densely populated region north of the river. The complex water management system and network applied by the Ruhrverband in the natural Ruhr River Basin has been developed step by step, over decades since 1913. And from the beginning, its major goal has been to achieve optimal conditions for the people living in the region. For this purpose, a functional water supply and wastewater disposal infrastructure has been built up. The development of these structures required and still requires multi-dimensional planning and performance. Since the river serves as receiving water and at the same time as a source of drinking water, the above-standard efforts of Ruhrverband for cleaner water also help to conserve nature and wildlife. Ruhrverband has summed up its environmental awareness in the slogan: “For the people and for the environment”. This basic water philosophy, successfully applied to the Ruhr for more than 80 years, will be continued in accordance with the new European Water Framework Directive, enacted in 2000, which demands integrated water resources management in natural river basins, by including the good ecological status of surface waterbodies as an additional goal.

In accordance with GOST 20793-2009, the tractor and its components are subjected to resource diagnostics before maintenance. The technical condition of the components of the tractor or machine should be checked with the use of control and diagnostic equipment. Currently, the criteria for the limit state are significantly outdated and require revision from the point of view of tightening modern requirements for operational and economic characteristics and reliability indicators. (Research purpose) The research purpose is in analyzing the state of the issue and the current regulatory documentation and making proposals for remote monitoring of the criteria for the limit states of individual components and aggregates. (Materials and methods) The article presents an analysis of scientific and technical documentation, State standards of the Russian Federation and scientific papers on the problems of minimizing technological risks, diagnostics and control suitability for determining the maximum technical condition, and staged studies on the possibility of monitoring the operation of individual components and units online. The article notes the need to adjust the criteria for the maximum technical condition in accordance with the new designs of resource-determining units, aggregates and existing technical regulations. (Results and discussion). The article presents the justification of the diagnostic process and identified contradictions in the design of tractors and existing scientific and technical documentation and standards, and proposed option of using meters-identifiers when upgrading tractors as a system of built-in online diagnostic tools. (Conclusions) Timely, automated monitoring of the technical condition of tractors, which is based on comparing data with the criteria of the limit condition, serves as a justification for the effective operation of equipment with built-in devices for diagnostics, which allows minimizing agrotechnological risks.
