Environmental Water Systems

What Environmental Water Systems does

Environmental Water Systems (EWS Inc.) is a privately held US manufacturer of residential and commercial water filtration, purification, and conditioning systems, founded in 1987 by CEO Howard and headquartered in Henderson, Nevada with product design and assembly in California. The company offers a portfolio built around granular activated carbon (GAC) filtration with proprietary ICN conditioning that prevents scale without salts, whole home systems (EWS Series with conditioning, CWL Series filtration-only) with flow rates up to 100 GPM, under-sink drinking water systems (ESSENTIAL line) with optional UV disinfection, reverse osmosis systems (RO3, RO4, RU500T35), and specialty systems addressing iron, manganese, hydrogen sulfide, and pH correction. Filtration media is rated for up to 10 years and appliances are documented to last 20+ years.

EWS generates revenue primarily through one-time hardware sales of filtration appliances, plus recurring replacement filters and media (whole home media every ~10 years, sink filters annually). The company distributes through 700-1,200+ kitchen and bath showrooms nationwide, supported by regional manufacturer representatives, three named authorized online retailers (WaterOnTheWeb, BigFrogSupply.com, DrinkingWellCo.com), and an in-house customer service team reachable by phone and email. Pricing is set by individual showrooms and retailers rather than centrally, and is not publicly disclosed.

The customer base spans residential homeowners (primary segment, served through the showroom network), commercial facilities (hotels, hospitals, healthcare providers), government/military installations, and well water users requiring specialty treatment. The company has held the exclusive water filtration appliance designation with the National Association of Home Builders (NAHB) since 1993 and has been featured in Men's Health, Professional Builder Magazine, and the Consumer Electronics Show. Ownership remains concentrated with the founder, with no disclosed venture capital, parent company, or public listing.
