Graywater System GWtec®

The GWtec® graywater system is designed to treat low-polluted wastewater (graywater) from showers, sinks, and bathtubs. Utilizing advanced GWtec® membrane technology, the system converts wastewater into high-quality non-potable water that meets the stringent hygienic and microbiological standards of European standard EN 16941-2 and aligns with US NSF/ANSI Standard 350 (Onsite Residential and Commercial Water Reuse Treatment Systems) as well as international IPC (International Plumbing Code) and UPC (Uniform Plumbing Code) requirements.

Proprietary Innovation

Globally Patented Technology: The GWtec® system and its advanced treatment processes are protected by international patents, ensuring cutting-edge, exclusive engineering for your projects.
