In recent years the search for sustainable technology has led the man of the field to innovate the means of production, especially family agriculture, which has found in social technologies its important ally in the creation of alternatives that can solve the problems of production and commercialization, within each territory. Water is a finite resource, without it we do not have the possibility of food production or life on the planet. Of all the activities that demand the need for water, agriculture is the activity that consumes the most water worldwide, being responsible for 70% of all the use made by human beings, and at the same time the most important, since without it, there is no possibility of food generation. Generating alternatives that will minimize the impacts of water use, whether family or agribusiness, is a challenge that drives research in the most diverse sectors in the world. Based on these statements, our work aimed to evaluate an alternative irrigation system to promote the reduction of the amount of water in vegetable production. For this, an alternative irrigation system was constructed using gravity and ascending flow, that is, benefiting the root of the plants. The methodology used was qualitative in nature, in which it addresses the description of the construction of the system at field level in orchard II of the school farm of IFRN Campus Ipanguaçu/RN and the boiling of moisture content using empirical method, with five contents ranging from dry to soaked, with collections at 3 depths, being 10, 20 and 30cm and the water flow was performed through a hydrometer with 300, 360 and 420 liters/hour. The results indicate higher humidity in the deeper layers, and the content ranging from humid to very humid on the days of collection. It is necessary to repeat the tests, in order to infer further results for the dissemination of technology among farmers and the use for the production of vegetables.
