Dimensionamento de reservatório para aproveitamento de águas pluviais em área agricultável

Abstract

The irrational use of water triggers serious consequences for the environment and the population's quality of life. Thus, the debates on the sustainable use of water were intensified. To promote this use, it is up to engineering to propose water use systems, then, this research had the objective of presenting the dimensioning of a rainwater capture and reuse system for irrigation in small rural properties. Using the Rippl’s method for dimensioning the rainwater storage cistern, calculating the water demand for common crops in rural properties, according to the reference evapotranspiration in the region of Dourados - MS. The methodologies of technical standards referring to cold water and rainwater building installations were also applied. According to the selected method, an 80 m³ cistern was obtained, meeting the annual water demand by more than 90%.
