Due to the scarcity or poor distribution of rain in some locations, alternative techniques for obtaining water should be studied. The objective of this work was to evaluate the feasibility of supplying with rainwater harvesting, all the irrigation demand of the vegetable garden sector of the Campo Novo do Parecis Campus, from the Federal Institute of Education, Science and Technology of Mato Grosso. The monthly amount of water to irrigate the vegetable garden sector was obtained from the water balance, using the values of precipitation, reference evapotranspiration of the crop and available water capacity in the soil. The period of greatest water deficiency in the region occurs in the dry season, between the months of May to September. The period of lowest water demands for irrigation, on the other hand, occurs between the months of October and April, in the wet season. To irrigate the 2,080 m² area of the vegetable garden with the use of rainwater, capturing rainwater in 1,922 m² of roof area, a reservoir with a capacity of 1,402 m³ is required.
