Rainwater use and automated irrigation for football stadium lawns – Morenão case

Abstract

Drinking water found in nature is facing shortages due to factors such as environmental degradation, population growth, and increased consumption in economic activities. This work focuses on the feasibility of capturing and storing rainwater to irrigate the lawn of the Pedro Pedrossian Stadium (Morenão) at the Federal University of Mato Grosso do Sul (UFMS) in Campo Grande, MS. The study involved an analysis of the Morenão Stadium facilities and the assessment of rainwater capture and storage opportunities. Sizing methods such as Rippl and Simulation were applied to determine the size of the reservoir. Executive projects and cost spreadsheets were developed for the rainwater harvesting and automated irrigation system, demonstrating that it is a viable option. The economic analysis considered two scenarios: the first, using rainwater, obtained a return on investment period of 10.7 years; and the second, without using rainwater, that is, only with the implementation of an automated irrigation system, but which would reduce water consumption from the concessionaire, has a payback period of 2.6 years.
