On the evaluation of the life cycle of the wells operating at the existing water intakes
Summary
Life cycle or useful life expectancy of fixed assets including water abstraction wells is regulated by RF Government Decree No. 1 of 2002. For water abstraction wells the life cycle is 15–20 years. Besides, the requirements to the life cycle in the environmental management system are formulated in the system of RF state standards authentical to ISO 14000. On the basis of the experience of operating underground water intake facilities is shown that reaching the design operating life is possible only on the condition of complying with the requirements to the selection of well filters and gravel packages for water abstraction mode that minimize the hydraulic losses in the near-filter zones. The guidelines for meeting these requirements have been formulated. At the stage of hydrogeological survey of the underground water resources assessment is suggested to make predictions of the water corrosiveness and the ability to release clogging compounds and biological colmatage.
Key words

Method and algorithm for estimating the life cycle cost of water supply and sewer pipelines
Summary
The issues of updating standard technical documents – codes of practice, state standards, instructional guidelines, as well as directions for their improvement to increase the efficiency of designing, building and operating public water supply and wastewater disposal systems in the cities and towns of Russia are considered. It is shown that recently the Russian construction sector has focused on updating and actualizing the regulatory framework in the field of design and construction in terms of reducing mandatory requirements in codes of practice. The main provisions and algorithm of the Method for estimating the life cycle cost of water supply and sewer pipelines are given. It is noted that there are a number of guidelines and standards explaining the procedure of estimating a life cycle. However, no method exists, so far, agreed upon either at the domestic or international level that could provide a reliable basis for comparing products and offers from different manufacturers. The estimation of the life cycle cost of water supply and sewer pipelines involves an economic analysis of the total cost of construction, installation, operation and disposal of pipelines made of various construction materials.

Development of the mechanisms of digital transformation of water utilities
Summary
One of the main challenges the Russian economy faces is the major upgrade and digital transformation of all the sectors including water supply and sanitation systems. The technological inferiority, depreciation of fixed assets and lack of investments hinder the development of the water industry. In these conditions, developing approaches and mechanisms to ensure the digital transformation of water utilities is required. Practice shows that one should start not with purchasing expensive software, but with developing a model of a water utility. As a result of the study, an approach to developing a digital model of a water utility based on the integration of ontological modeling its activities, modernization tools for water utilities and computer technology was proposed. A number of effective tools for upgrading water utilities are considered: GIS- and BIM-technologies, methods of operating water supply and sanitation facilities, etc. The concept of a «digital model of the water utility activities» is substantiated and the structure of the basic elements of the conceptual level of this model considering the specifics of the water utilities is proposed. The practical application of the new approach will contribute to the effective digital transformation of water utilities and the enhanced development of the water industry with timely updating fixed assets, taking into account cost savings and improving the quality of services.
