Preventing water pollution from global change is essential. In this regard, at a new stage in
Uzbekistan's development, the government has adopted a number of resolutions and decrees, which
are mainly aimed at improving the sanitary state of water supply and sewerage systems. The President
of the Republic of Uzbekistan Shavkat Mirziyoyev emphasizes the need for "rational use of land and
water resources, the rapid introduction of market principles, advanced achievements of science and
technology in relations between agro-industrial organizations ..." [1]. This places modern demands
on the level of treatment of treated wastewater discharged into double reservoirs.
In modern Uzbekistan, as in all spheres, new water management structures are being created to
ensure effective regulation of water use, active work is underway to attract the private sector to water
supply and sanitation. Including, the Decree of the President of the Republic of Uzbekistan dated
November 26, 2019 No. PP-4536 "On further improving the water supply system of the republic" and
the Decree of the President of the Republic of Uzbekistan dated November 26, 2019 "On improving
the quality of drinking water, Resolution PF-5883" On measures to improvement of the water supply
and sewerage system ”became the basis for a new stage in the further development of water supply
and sewerage.
The country is carrying out consistent reforms in the field of water use, including water supply
and sanitation, comprehensive measures are being taken to ensure the rational use of water, its quality
and safety, as well as the introduction of modern innovative water consumption systems. In addition,
on the agenda today is the consistent continuation of work to improve the water supply system, attract
foreign investment in the sector and develop the country's drinking water supply and sanitation
infrastructure. Accordingly, on the basis of state unitary water supply enterprises that are part of the
system of the Ministry of Housing and Communal Services of the Republic of Uzbekistan, the
Uzsuvtaminot joint stock company was created by reorganizing these enterprises into limited liability
companies [2].
The biggest issue in the modernization of water supply systems is the adaptation of water
pumping stations to the requirements of today. Modern pumping stations now must be more efficient
and productive than before.
The use of energy-saving methods and means of operating pumping units for water supply and
sewerage systems is increasingly being used. This leads to a significant reduction in energy
consumption. However, we need to be able to adequately control the best performance (in terms of
efficiency, productivity and specific energy consumption) [3] after modernization (replacement of
pumps). Firstly, it will become the basis for the introduction of a new concept of "virtual pump" and
the creation of mathematical models of virtual and real pumping units operating at constant and
variable speed. Secondly, as a result of the effective use of technology, it will be possible to determine
the optimal parameters of energy-efficient pumping units. Third, current approaches to determining
the efficiency of pumping units are useful in determining whether the target value for the maximum
energy efficiency required to determine the energy saving capacity of pumping systems of systems is
a target function of energy supply costs.
Much work is underway in Uzbekistan to introduce drip irrigation technology, which is one of
the most advanced methods of irrigating crops. Drip irrigation, which is a modern method, is
