Patrícia Cecília Rodrigues Mapa da Fonseca isn’t just a civil engineer—she’s a force to be reckoned with. Day by day, this relentless researcher has solidified her place as one of the sharpest minds in water resource management, with an unwavering focus on rainwater. Her articles, published in heavyweight scientific journals, are rewriting how the world tackles the water crisis, and her name is already echoing among the planet’s top experts. As a Senior Member of the IEEE (Institute of Electrical and Electronics Engineers)—a distinction earned by only 10% of its members—Patrícia belongs to an elite, prestigious group where her work doesn’t just stand out; it’s shaping the future of engineering and sustainability.
With a career that fuses technical brilliance with a burning passion for sustainable solutions, Patrícia has turned rainwater harvesting into a powerhouse strategy against water scarcity. Her article “Impact of Rainwater Harvesting on the Conservation of Water Sources and Water Security” (International Seven Multidisciplinary Journal, 2023) is a game-changer. In it, she breaks down how cisterns, infiltration wells, and green infrastructure can ease the strain on water sources, curb floods, and secure water for generations to come. “It’s not just about collecting water; it’s about breathing life back into water systems,” Patrícia declares, her vision leaping off the page and making a tangible difference in cities like São Paulo and the Federal District with real-world success stories.
Another powerhouse piece, “Economic Analysis of Implementing Rainwater Harvesting Systems in Residences” (Revista Científica Sistemática, 2025), puts hard numbers on the table: up to 40% of household water use can come from rain, slashing costs and challenging reliance on traditional sources. She takes it further with “Implementation of Rainwater Harvesting Systems in Single-Family Homes” (RevistaFT, 2022), a study that’s opened doors for public policies and private initiatives, proving sustainability and savings go hand in hand. Her calculations show investment returns ranging from 6 to 10 years, depending on local tariffs and climate—an airtight case for anyone still on the fence.
As a Senior Member of the IEEE, Patrícia stands among a global elite that blends engineering and innovation with mastery. Her articles aren’t just read—they’re debated, put into action, and celebrated. From Goiânia to Blumenau, her analyses cover everything from the upfront costs of cisterns to aquifer recharge, offering a clear roadmap for public officials and homeowners alike. In São Paulo, her research has already helped spark practical solutions, cutting treated water use by up to 30% in some areas. Her work isn’t just academic—it’s a call to action, backed by data and driven by a fierce commitment to a better world.
