APROVEITAMENTO DE ÁGUA DA CHUVA PARA IRRIGAÇÃO DO GRAMADO DO ESTÁDIO PEDRO PEDROSSIAN (MORENÃO) EM CAMPO GRANDE – MATO GROSSO DO SUL

Abstract

Water is a fundamental, essential and irreplaceable resource for the existence of life, being considered one of the most precious natural assets. However, drinking water or fresh water, which occurs naturally in the environment, is facing scarcity due to several factors, including environmental degradation, population growth, inadequate water utilization and increased demand in economic activities, covering sectors such as commerce, industry, agriculture and livestock, among others. The present work aims to identify and apply best practices for irrigation and water storage, which can be applied in football stadiums. A study was developed on the feasibility of capturing, reserving and using rainwater for automated irrigation of the field lawn at the Pedro Pedrossian Stadium (Morenão), located on the campus of the Federal University of Mato Grosso do Sul. This study involved in-depth surveys. location and in plans of the facilities, as well as an analysis of opportunities for capturing and storing rainwater for later use in lawn irrigation. For the sizing of the reservoirs, the Rippl and Simulation Methods were applied. A project for implementation is also presented in this work, with spreadsheets and technical details for the system for using rainwater and automated irrigation for the football field. The economic analysis was based on two scenarios: using rainwater and automated irrigation, including all implementation costs, with a projected return on investment in 10.7 years; and a second scenario without using rainwater, only with the implementation of the automated irrigation system, using the existing infrastructure, presenting a return on investment in 2.6 years.
