Epic Cleantec - Model OneWater™ -Onsite Water Treatment System
The OneWater™ system by Epic Cleantec is an integrated onsite water treatment solution capable of recycling up to 95% of a building's wastewater, including greywater, blackwater, rainwater, stormwater, condensate, and foundation drainage. The system employs a multi-barrier approach that combines ultrafiltration membranes, advanced disinfection methods, and heat recovery to produce highly purified water for non-potable reuse applications like toilet flushing, cooling tower makeup, irrigation, and laundry. Designed for seamless integration into various building types, the system is fully automated, enabling remote monitoring and minimal manual operation. Its cloud-based interface features a customizable Eco-Insights dashboard, providing real-time system health data, utility savings, and performance summaries. Epic Cleantec collaborates closely with stakeholders to tailor each solution, addressing global water challenges by reducing resource consumption, energy costs, and environmental impact.
Epic’s OneWater™ system can safely recycle up to 95% of a building’s wastewater to produce three sustainable outputs:
- Recycled water that can be reused directly onsite for non-potable applications like cooling towers, toilet and urinal flushing, irrigation, or clothes washing;
- Recovered energy from wastewater heat can be captured and used to preheat domestic hot water supply;
- Repurposed natural soil amendments that can be used in landscaping projects, gardens, or even local parks.
Our system is unique in that it can integrate various wastewater sources within a building — including greywater, blackwater, rainwater, stormwater, condensate, and foundation drainage — into a single management system. This holistic approach ensures maximum efficiency and resource recovery, unlike conventional onsite systems that typically focus on just one type of water.
- Prefiltration and Equalization
Water collected from showers, sinks, toilets, washing machines and other wastewater sources is prefiltered then stored in an equalization tank that buffers out flow, reducing the size of the downstream system. - Biological Treatment
The raw water undergoes biological treatment for removal of organics, known as Biological Oxygen Demand, or BOD. During the aerobic or anaerobic step, microorganisms metabolize organic compounds in the wastewater, degrading them into simpler substances such as carbon dioxide, water, and biomass. - Membrane Filtration
Water is then rigorously filtered using membranes with a nominal pore diameter of .04 microns – about 1750X thinner than a single human hair – to remove any remaining impurities. - Disinfection and Heat Recovery
Before pumping for reuse in the building, water undergoes multiple steps of disinfection via ultraviolet light and chlorine, which render the water safe for reuse in non-potable applications. If heat recovery is included, the system can capture that energy and use it to pre-heat the incoming supply, ultimately reducing hot water demand and cutting down on energy costs.
The OneWater™ system safely treats and recycles water onsite for non-potable reuse applications like toilet and urinal flushing, cooling tower makeup, irrigation, and clothes washing. Leveraging a multi-barrier approach that includes ultrafiltration membranes and state of the art disinfection systems, the OneWater™ system produces a highly purified final product that is guaranteed to meet regulatory requirements for interior and exterior recycled water reuse, meeting disinfected tertiary reuse effluent standards.

Physical specs & features
- Systems occupy just a few parking spaces' worth of square footage and are designed to be the most space-efficient water reuse technology in the market
- Built for deployment of any scale, our system can process flows ranging from 1,000 to 30,000 gallons per day
- Complies with local and state public health regulations while our O&M team monitors the system 24/7
Immediate impact & benefits
- Helps building owners achieve Net Zero Energy goals — one of the only systems designed to integrally treat wastewater & recover heat from the wastewater stream for return to the building
- Reduce building energy consumption by recouping lost thermal energy that otherwise gets washed down the drain
- Save money on water and sewer costs by reducing the building’s water demand from municipalities
