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.
