Project Description: RainCatcher 2.0 is an innovative rainwater harvesting system designed to tackle urban water wastage and promote sustainable cities. Developed by young changemakers, the project focuses on Surat’s 115+ bridges where millions of liters of rainwater are lost every season. Our model simulates rainfall, detects it using sensors, collects and filters the water into a storage tank, and displays real-time data using an LCD. Powered by an Arduino UNO for bridge automation and a Quarky board for smart irrigation, the system also uses soil moisture sensors and a water pump to ensure precise watering for plants—wasting zero water. With the potential to save over 9.02 billion liters annually, RainCatcher 2.0 turns existing infrastructure into eco-smart assets without any new construction. It’s simple, scalable, and student-built—a bold step toward water-wise, greener cities.
