Irrigating farmland in Romania has become an increasingly necessary technique as climate change has become a constant reality. Irrigation management is subject to particular urgency due to increased water consumption through evapotranspiration which requires higher flows from water sources, transported through channels and distributed under pressure to the crop land. During the process, pumping stations are the highly demanded elements of the hydrotechnical scheme, since they must have the ability to pump the required flow rates. Research to assess this issue was carried out in the Gostinu-Greaca Argeș facility, in the Prundu-Chirnogi Organization of Irrigation Water Users (OUAI). The increase in irrigation water needs was determined by comparing the irrigation regime calculated for two different climatic periods: the reference period when the climate was more stable and the current period characterized by climate change. Based on the data obtained, operating charts of the pumping stations were developed to show that they did not have the capacity to provide the necessary flow rates for irrigation during the times with maximum water consumption. The issue was solved by reorganizing watering application. There were also situations when, even after the reorganization of watering application, the installed flow rates were exceeded by the water needs, which required the adaptation of the watering rules according to the size of the installed flow.
