The objective of this research was to design and evaluate the scenarios for the efficient use of water and energy in a pressurized irrigation system case: Fundo agrícola at the Universidad Agraria La Molina, different irrigation systems were designed, the efficiency of irrigation, energy and energy costs and CO2 emissions were estimated, to be compared later. The water balance, agronomic design, uniformity coefficient, and irrigation efficiency were carried out, taking into account the sensitivity of the crop to salts and the electrical conductivity of the water. Different scenarios were proposed for the same area and crop: constant flow and variable total dynamic head, variable flow and constant total dynamic head, variable total dynamic head and flow, constant total dynamic head and flow, and pumps in parallel. The energy costs were calculated without and with the frequency inverter. The permitted and permitted operating region was determined and the CO2 emissions were calculated without and with the frequency inverter for the different scenarios. The results were obtained that high energy efficiency values do not guarantee lower energy costs, however the use of frequency inverters allowed energy savings and emission reduction for the first scenario of 17.45 %, second scenario of 29 % and third. scenario of 29.30 % per year with respect to the non-use of the frequency variator, the variators allow the reduction of CO2 of all the scenarios proposed and the recovery of the investment varies between 5 to 8 years
