<p>The article presents findings from research into practical application of a jet pump utilizing flow energy in view to improve energy efficiency of vertical drains in irrigation and reclamation systems. Increasing demand for electricity and its rising cost nowadays dictate the need for energy efficient mechanisms to reduce the energy consumption of pumps used for land reclamation and irrigation. Works on practical application of the jet pump were carried out on vertical drainage in the area of Gulistan city of Syrdarya province, test works were implemented in field conditions in the range of hydraulic parameters of water flow rate 0,8-1,6 l/s and the pipeline pressure of 0,5-1,0 atm. Comparative evaluation of results from the field and laboratory tests retrieved relationships between relative flow rate and relative head. Their level of accuracy is based on the correlation coefficient (R2 = 0.91). The paper provides conditions and recommendations for the use of jet pumps in vertical drains.</p>
