How RainCycle™ Works

Rainwater harvesting offers a sustainable approach to water management. It not only helps commercial and industrial buildings conserve water by reducing the demand on municipal water sources, it can reduce energy consumption and provide economic savings.

Learn how the RainCycle™ Rainwater Harvesting system easily collects rooftop rainwater and then pre-filters, stores, processes and distributes it as non-potable water for such end uses as restrooms, irrigation, and cooling tower water makeup.
