Greyter Water Systems Inc. was an Ontario, Canada manufacturer of onsite greywater recycling and water reuse systems, founded in 2012 after acquiring the assets of the defunct Brac Systems. Its flagship Greyter HOME captured water from showers and bathtubs, treated it, and returned clear, odor-free water for toilet flushing, cutting a family home's indoor water consumption by up to 25 percent; it earned NSF/ANSI 350 Class R certification in early 2019 as the first compact residential greywater reuse system to hold that designation. A scaled commercial line served water harvesting and reuse for toilet flushing and cooling towers in multi-unit and institutional buildings, and the systems were installed in more than a dozen countries. The company raised roughly $13M through a Series B. Its only software was an end-user monitoring surface — the mygreyter.com portal and a consumer Greyter mobile app used by owners to watch water savings — and it never published a developer program, public API, SDK, webhooks, or any machine-readable specification. Greyter Water Systems Inc. filed for bankruptcy on January 8, 2026, with GlassRatner Restructuring Inc. appointed Trustee and its intellectual property, patents and customer lists placed into an asset sale process. This profile is retained as a historical record; there is no API surface to enrich.
