The new system captures and recycles rainwater and HVAC condensate onsite, helping developers and property owners cut costs, meet sustainability goals, and future-proof their projects.
Epic Cleantec, a pioneer in onsite water reuse solutions for the real estate industry, unveiled its next-generation OneWater™ Rain system today at Greenbuild 2025 in Los Angeles, marking a major step forward in water technology innovation.
The OneWater Rain system is an advanced, modular water recycling solution that captures and purifies rainwater and HVAC condensate for reuse across a range of non-potable applications, including for irrigation, toilet flushing, cooling tower makeup, and laundry.By transforming these overlooked water sources into a sustainable supply, the system helps developers and property owners reduce utility costs, achieve sustainability goals, and strengthen resilience against drought and infrastructure strain.
Rainwater reuse represents one of the most accessible and impactful decentralized water strategies in North America. Numerous studies across the U.S. and Canada have shown that capturing and reusing rainwater can offset 20–40% of a building’s total non-potable water demand, depending on local rainfall and end use. Beyond reducing reliance on municipal supply, rainwater systems help mitigate urban flooding, lower combined sewer overflow risks, and improve overall water resilience.
Similarly, individual properties can waste hundreds of thousands of gallons of HVAC condensate annually. The OneWater Rain system captures these largely untapped flows and converts them into high-quality recycled water that supports both environmental performance and financial returns.
Engineered for flexibility, the OneWater Rain is designed to integrate seamlessly into both new construction or retrofit projects, making advanced water reuse accessible to a wider range of developments than ever before. The system’s plug-and-play modular architecture minimizes installation time and space requirements, while its sophisticated AI-enabled operating platform continuously optimizes treatment, storage, and reuse in real time for maximum efficiency and reliability.
