GreenLED seeks to demonstrate the effectiveness of rainwater as an alternative water source while complying with health and water quality regulations.

The project introduces a comprehensive system combining collection, biological treatment, and aquifer storage of rainwater, with UV-C LED disinfection prior to reuse. This chemical-free, natural, and environmentally friendly approach removes pollutants, offering a circular water management solution. The resulting high-quality water is suitable for close-contact urban applications, contributing to climate adaptation and water neutrality.
