The current state of the water regulatory framework

Summary

The legal and regulatory framework of designing, building and operating water supply systems with surface and underground water abstraction (resource block), technical process solutions and equipment, development of sanitary requirements to the quality of water sources and of water supplied to the population, rules of operating water supply systems are considered. The development of the water legislation in the country is related to the introduction into force of the RF Water Code in 2006 and amendments to it. The use of underground waters is regulated by the Federal Law «On subsurface resources», «Classification of reserves and predicted resources of drinking, process and mineral underground waters» and by guidelines on its application. The drawbacks of the existing documents related to finding ground waters in natural conditions that meet the requirements of sanitary authorities to the drinking water are noted. The analysis of the formation of the regulatory framework of technologies shows that there are progressive trends related to the adoption of 416-ФЗ Federal Law «On water supply and wastewater disposal». At the same time it is shown that updating SNiP 2.04.02-84 in the form of 31.13330 Set of Rules has a number of drawbacks. When considering the sanitary safety of water sources the necessity of early adopting public health regulations related to water supply source selection (replacing GOST 2761-84), revising SanPiN 2.1.4.1110-02, developing legitimate recommendations on hydrogeologic methods of estimating the dimensions of sanitary protection zones, and developing the mechanism of adjustment of maximum permissible concentrations of components regulated by SanPiN 1.2.4.74-01 harmonized with WHO requirements is pointed out. It is shown that the robustness of water supply systems is ensured by the motivated selection of water supply sources and designs of water intakes, systems of water purification, supply and distribution. At the same time it is necessary to carry out process studies of remediation of water resources with account of the RF state standards of ISO 9000 and ISO 14000 series.

Energy efficiency of pumps in water supply and wastewater disposal systems

Summary

The aspects of anti-terrorism security of water supply and wastewater disposal facilities are considered alongside with the dynamics and structure of the Russian domestic market of pumping equipment for water supply and wastewater disposal systems. Current world trends in improving pumping equipment in relation to furnishing with the systems of intelligent management and control and improving energy efficiency within the frames of «Internet of things» (IoT) concept cause problems in interdisciplinarity. The Soviet experience in improving the domestic approach to the assessment of the energy efficiency of pumping systems in the process of ISO/ASME 14414 standard revision is considered. The criteria of the energy efficiency of pumps for water supply and wastewater disposal systems are presented; their advantages and continuity of the similar international practice are shown. In order to determine what pumps manufactured in the Russian Federation and imported to RF are energy efficient in relation to the operation requirements for water supply and wastewater disposal systems it is necessary to define on the basis of the currently available best practice a common approach to the assessment of energy efficiency that can be used by both manufacturers, designers and users of pumping equipment, and by public oversight and monitoring authorities. Pumping equipment that does not meet such requirements must be excluded from the official stream of commerce in water supply as not compliant with the current ecological requirements and put on the restriction list in RF. The problems of interdisciplinarity in relation to the assigned use in safety critical industries of the domestic radioelectronic element base, domestic operating systems, software in instruments and systems of monitoring and control of pumping equipment of water supply and wastewater disposal systems warrant solutions. Allocation of public funds for equipment integrated with data processing centers located overseas must be limited.

Efficient control of water supply and distribution system of the Moscow megalopolis

Summary

The existing system of Moscow water supply is a comprehensive complex of engineering facilities that provide for uninterrupted supply of potable water to the city inhabitants. The main task of the system control is to assure delivering the required amount of high quality potable water alongside with maintaining optimal operation mode of all the water facilities. The main aspects of the efficient water supply control are as follows: predicting daily and hourly water consumption in the city; planning amount of delivery by the water treatment facilities; assuring operational control (of pressure, quality); computerizing control processes. Improving the efficiency of such a large-scale system may be possible only by investigating and introducing innovative solutions, integrated use of information technologies including GIS, modeling flow distribution in the water distribution network, and computerizing water delivery and distribution modes.
