What N-Viro International does
Nviro, Inc. is a San Luis Obispo, California-based water and wastewater treatment solutions provider offering custom-engineered systems and full-service design-build delivery to industrial, commercial, and municipal clients. The company serves twelve identified verticals — primary markets include data centers, wineries, food and beverage processors, municipal water/wastewater utilities, and community service districts; secondary markets include buildings and facilities, agriculture, hospitality and recreation, general industry, oil and gas, and energy and power — with all disclosed activity concentrated within California under a state contractor license (CA Lic #1056567).
The technology stack spans the full treatment train: preliminary systems (headworks, equalization), biological treatment (Activated Sludge, Sequencing Batch Reactors, Fixed Film Reactors, Moving Bed Biofilm Reactors, Membrane Bioreactors), aeration, filtration and membranes (Reverse Osmosis, Ultrafiltration), disinfection (UV, Ozone), and solids handling (dewatering screws, pump skids). Industrial control is delivered through UL 508A/698A-certified control panels integrating SCADA, PLC, and HMI on Ignition (Gold Certified Integrator), Wonderware, and Rockwell Automation platforms. Manufacturing is performed in-house at the San Luis Obispo facility using precision fiber laser cutting, MIG/TIG welding, and stainless-steel tank fabrication, supporting both custom-built plants and standardized modular treatment systems.
Revenue is generated through four streams: equipment sales of engineered treatment systems, design-build engineering and construction services, ongoing operations/maintenance/compliance managed services, and industrial control panel fabrication. Pricing is quote-based with no public tiers, contracts are multi-year, and the go-to-market is direct enterprise field sales initiated through no-obligation consultations. Note: the operating entity Nviro, Inc. (privately held) and the ticker-bearing N-Viro International Corporation (OTCMKTS:NVIC) appear in the source material as related but not unambiguously the same legal entity, with no disclosed ownership linkage between them.
