The OneWater™ Rain system is best suited for commercial, industrial, multifamily residential, and mixed-use developments that seek to implement onsite water reuse for non-potable applications. [Source]
The system is designed to collect and treat rooftop rainwater and air conditioning (AC) condensate for onsite reuse. [Source]
No, the OneWater™ Rain system is specifically designed to treat rainwater and condensate only. For stormwater recycling solutions, contact the Epic Cleantec sales team. [Source]
The primary purpose is to provide a renewable, high-quality non-potable water supply for buildings by capturing and treating rainwater and condensate, reducing reliance on municipal water and supporting sustainability and regulatory compliance. [Source]
The treatment process includes collection and first flush (diverting initial runoff), storage in a cistern, filtration to remove sediments, and disinfection using UV reactors (and optionally chlorine). This ensures water meets non-potable reuse standards. [Source]
All models include ethernet connectivity (with optional cellular data), PLC & HMI controller, and optional BMS and SCADA integration. Remote monitoring, control, and data logging are standard. [Source]
Tank working volumes, instrumentation, water quality unit processes, plant pumping, and purified water control strategy are all customized to meet the specific needs of each project. [Source]
Standard inclusions are loose ship components for field mounting, and the main skid, which can be located indoors or outdoors. [Source]
Installation, interconnecting piping and wiring, reuse pumps, rainwater diversion, potable water makeup, municipal bypass valve, tank design and supply, safety shower, utility sink, building and room features, and chemical storage are not included as standard. Some are available as options. [Source]
The system is available in four models: OWR-20, OWR-40, OWR-60, and OWR-80, with maximum processing capacities of 20, 40, 60, and 80 gallons per minute (GPM), respectively. [Source]
The main skid dimensions for OWR-20, OWR-40, and OWR-60 are 63" x 30" x 60". The OWR-80 model measures 77" x 30" x 60". [Source]
The main control panel operates at 120V, single phase, with amperage ranging from 25A (OWR-20) to 32A (OWR-80). Alternate voltages are available upon request. [Source]
Plumbing connections are typically 1.5” or 2” PVC80, depending on the model and whether a sand filter is included. [Source]
Accessory components include cartridge filters, sand filters (project dependent), blowers, cistern transfer pumps, cisterns, and day tanks. Sizes and specifications are tailored to project needs. [Source]
Key considerations include upstream diversion for O&M flexibility, sufficient storage, waterproofing of tanks/cisterns, a local operator/lab sink and work table, high-speed internet, room drainage capacity, and day tanks for multiple reuse types. [Source]
The system targets pathogen reduction (validated by UV dose and chlorine residual), water clarity within validated UVT range, and total coliform bacteria limits: 7-sample median < 2.2 MPN/100 mL, 30-day max 23 MPN/100 mL, absolute max 240 MPN/100 mL. [Source]
Treated water from the OneWater™ Rain system is approved for non-potable uses such as toilet flushing, irrigation, cooling tower makeup, and clothes washing. Some states also allow treated rainwater for potable use. [Source]

Epic Cleantec’s OneWaterTM Rain system captures, treats, and reuses rainwater and AC condensate to create high-quality non-potable water supply for real estate projects. Our process combines advanced filtration and disinfection into a single platform, ensuring consistent water quality. Our goal is to help your project reduce its dependence on municipal supply, and to provide a renewable source of water that aligns with both regulatory compliance and sustainability goals.
Rooftop rainwater and AC condensate is collected. The first flush diverter directs the initial roof runoff (which contains higher pollutant loads such as dust, animal droppings, or rooftop debris) to the storm drain.
Collected water is stored in a cistern and any excess water is discharged. The cistern serves as the primary buffer, allowing solids to settle and providing a reserve volume for treatment.
Filtration removes fine sediments and particulates. This protects downstream equipment from fouling and ensures the water meets turbidity limits for pathogen crediting.
Ultraviolet (UV) reactors deliver a validated dose (>40 mJ/cm² per EPA UVDGM or NSF 55 Class A), inactivating pathogens like bacteria, protozoa, and viruses. For some applications, chlorine is used as a secondary disinfection method. A sample port allows operators to collect water for testing.
