Since reducing energy consumption is a priority for an enterprise, economic effi ciency in general is directly related to the use of pumping equipment. The demand for electricity for pumping equipment will depend on various factors: the operating modes of pumping stations and installations, the equipment used measures to reduce the cost of electricity consumed, etc. The current practice indicates extremely inefficient operation of pumping equipment. Currently, a large number of pumping stations of water supply and sanitation systems operate in an uneconomical mode. Very often, this is due to incorrect selection of pumping equipment, outdated pumping equipment, the operation of pumps in non- calculation mode. In addition, pumping equipment has been installed in many industries since the establishment of production. Such equipment is morally and technically outdated. Now,technological progress allows us to use more efficient equipment and materials that allow us to reduce energy consumption. The article presents an analysis of the energy consumption of a pumping station of technical water supply on the example of JSC «Omsk Kauchuk», a variant of modernization is proposed in order to reduce the consumption of electricity by pumping equipment. The need to modernize the pumping station of technical water supply is associated with a significant service life and high –energy consumption of pumping equipment. Two pump brands were selected and a comparative analysis was carried out. Based on calculations of energy consumption and technological characteristics, the most profitable and optimal version of the D6300-80-2b pump was chosen, since the pump performance is greater and the power consumption is less than that of the JETEX DS600-750 pump, as well as reducing the wear rate of operating elements, improving the pump’s suction capacity

Water supply pumping stations are among the main energy-consuming elements in the water supply system. The energy optimization of a pumping station can significantly affect the energy consumption of a water utility. This article deals with the energy optimization of water pumping stations. The work assumes several variants of optimization of water supply pumping stations through changes in the water supply system, pressure changes in the pumping station, and modification of the number of pumps. After analyzing the network, conducting field tests, and creating a model of the water supply network, the network was calibrated in order to reproduce the existing water network as accurately as possible. Then, a variant analysis was performed, and the best optimization method for the pumping station was selected. In two variants, there was a decrease in electricity consumption; in three there, was an increase; in one, there was no change. By connecting the DMA zones and modifying the pressure in the pumping station, the energy consumption of the pumping stations was reduced. On this basis, it was found that it is possible to optimize the water pumping station by modifying the pumping station and work related to the network layout.

The main energy consumers in sewer networks are the sewage pumps. Therefore, to minimize the energy consumption, it is essential that these pumps operate under satisfactory conditions. Knowledge about the efficiency of the pumps and their operating conditions can help the pump station management to operate the system optimal. In the search for innovative solutions that can help the sewer management with this information, we propose a method that provides information on the pump flows, the inflow to a sewage pit, and an online estimate of the efficiency of the pump. All these information are obtained without a flow sensor. We argued that the calculated flow values can be used by the sewer management to optimize the operation on the sewer pumps, and the efficiency estimate can be used for optimal scheduling of maintain procedures. The flow and the efficiency estimations are exemplified on a pumping station of the sewer network in Herning, Denmark.

Линейная удаленность объектов в г. Новокузнецке достигает 40 км с разницей высотных отметок 157 м. Два главных водозабора города удалены друг от друга на расстояние 20 км, что предполагает наличие зон с разным свободным напором. Управление давлением и распределение воды по районам традиционно осуществлялось дросселированием запорной арматурой, а в исходной схеме водоснабжения функционировали 119 насосных станций с агрегатами мощностью от 0,75 до 1250 кВт. По результатам анализа возможных путей решения проблемы были сформированы предложения по установке редукционных клапанов, разработана схема их установки и определены режимы работы новой системы. Установка регуляторов по всему городу решалась в два этапа. В 2016 г. в результате установки семи регуляторов были остановлены 13 повысительных насосных станций общей мощностью более 150 кВт. На втором этапе в 2017 г. были установлены еще 12 регуляторов и остановлены 8 станций общей мощностью 40 кВт, а на пяти станциях была выполнена оптимизация с заменой насосов агрегатами меньшей мощности. Окупаемость проекта составила 4 года.The linear remoteness of the water facilities in the city of Novokuznetsk reaches 40 km with a difference in elevations of 157 m. The two main water intakes of the city are located at the distance of 20 km from each other, which suggests the availability of zones with different free head. Pressure control and water distribution among the districts was traditionally carried out by throttling shutoff valves, and 119 pumping stations with pumps of 0.751250 kW capacity were operating in the initial water supply scheme. Based on the analysis of possible solutions to the problem, proposals were made for the installation of pressure reducing valves, an installation diagram was developed, and the operating modes of the new system were determined. The installation of regulators throughout the city was carried out in two stages. In 2016, as a result of the installation of 7 regulators, 13 booster pumping stations with a total energy consumption of more than 150 kW were phased out at the second stage in 2017, 12 more regulators were installed and 8 more pumping stations with a total energy consumption of 40 kW were put out of operation and 5 pumping stations were upgraded with pump replacement for lower capacity. The project payback period was 4 years.

Between 1999 and 2007, several successive years of severe drought put South East Queensland's water supply under immense pressure. The decision was taken in 2005 to build a seawater desalination plant and three water recycling advanced treatment plants as part of a large investment plan to secure the region's potable water supply. The infrastructure built and commissioned in the past 3 years has a combined capacity producing more than 350,000 m3 per day of very high quality water that can be used either directly (seawater desalination) or indirectly (recycled water) for supplying drinking water. All the plants primarily rely on reverse osmosis membranes for water purification which is an effective and reliable barrier to contaminants, but also requires high energy consumption and a high level of pre-treatment and chemicals. In this paper, the actual energy consumption of two of the plants (the seawater desalination plant and one water recycling plant) was investigated with the perspective of drinking water production over the July 2009–June 2010 period. Eolia™ Potable Water, a Life Cycle Analysis tool developed by Veolia Environnement Research & Innovation, was used to model the processes and estimate the greenhouse gases (GHG) emissions from both plants. As expected, the energy requirement of the desalination was higher (approximately 2.2 times) than the water recycling plant. The plants were found to be significantly more energy efficient when operated at higher flow. In both cases, the purchase of electrical energy represented by far the major contribution to GHG emissions. Indirect GHG emissions from chemical consumption could be reduced at the water recycling plant by optimising the dose of ferric chloride used at the plant and sourcing the chemical from a less distant supplier.

Republic of Uzbekistan, pumping stations are used in very difficult conditions. The presence of various particles and effluents in the water has a negative effect on the operating modes of the pumping equipment. Special grilles are installed to prevent the catching devices from entering the advance chamber of the pump station. The shape and length of the device covers are of great importance so that they are caught in front of the grilles and completely cover the accumulated debris. In the article, the laws of mechanics were used to determine the shape and size of the working device of the device for cleaning the effluent flowing into the pump station as water and accumulated in front of the grids. In doing so, the condition of ensuring complete removal of the leaks covered by the device was taken into account. It was argued that the angle γ between the working surfaces and velocities of the covers should be less than 90-φ over its entire working surface in order to fully cover the device shafts. It was found that when the working surface of the device is flat, the time of interaction with the catching device pieces is minimal. Studies and literature have shown that the angle of friction on the working surfaces of the device covers should be φ=20°, the angle between the working surface of the device cover and the rotational speed γ=70°.
