Abstract Water is one of the main resources of all economic activities and one of the natural resources that God has given to mankind. It is the essential source for the survival of the world. In the light of the Egyptian water balance system, which means "determining the quantities of water entering or leaving any water system" The total volume of conventional and non-conventional water resources (water supply) over a given period of time, and the total volume of water needs required to meet the various needs (water demand), thus increasing the gap between water supply and demand. The research, in which we proved in the end that the first and second assumptions, which provide the following: The rationalization of consumption of water resources is one of the important alternatives to achieve water security - The application of modern irrigation systems can contribute significantly to reduce the waste water consumption: The capital requirements for the five systems in tables A1 to A8 at the end of the study illustrated that the capital investment costs of irrigation systems are inversely proportional to the length of the field and with the increasing investment in irrigation of acres. The economic profit is achieved by operating the systems that need the greatest possible time with low costs The system is also the most efficient and uses the smallest amount of water per minute for surface irrigation systems, which is a great reason to rationalize the water of immersion to reduce the costs and narrow the gap between supply and demand of water in the future.
