The course work includes water supply to the city of Taraz. The area of the city is 92.75 hectares. here water supply systems are designed to meet the domestic and economic needs of the consumer. A water meter is placed in the water to determine the total flow of water. The source of water supply is a ring water pipe with a diameter of 100-250 mm along the street.

The water consumption for urban water supply is 90.02 l /s. Number of cycles 4, number of nodes 9. The water consumption for washing along the streets of the city is 6.3 m3, the diameter of the nodes is 100 mm. The water consumption for irrigation of green spaces of the city is 29.4 m3, the diameter of the canals is 100-250 mm. The height of the single-pitched tower Nm = 20.09761 m.

When calculating the exchange rate project, we calculate the daily mode of operation of pumps supplying water to this city, calculating the water supply of one quarter, as well as the daily costs of landscaping and washing city streets.

When water supply to Taraz, the diameter of the pipes was selected in the range of 100-500 mm. Pipe material steel. During the project, losses in nodes, piezometric losses, free losses, height of the tower losses were determined.
