International Water-Guard

What International Water-Guard does

International Water-Guard Industries Inc. (IWG) is a privately held Canadian aerospace component supplier, founded in 1989 and headquartered near Vancouver, British Columbia. The company designs, manufactures, and services flight-certified potable water treatment and heating systems for aircraft, serving both business aviation (private and VIP jet manufacturers, completion centers, MRO facilities) and commercial aviation (airlines and aircraft OEMs such as the Boeing 737 Max platform via Flair Airlines).

IWG's core technology is centered on UV water purification — its UV treatment units (NPS-A6, IWG-UV1/UV2/UV3, IWG-A4/A6, NPS-A3/A2, IWG-UVL1) are flight-certified and benchmarked to National Sanitation Foundation Standard 55, Class A-40mw/cm2, covering flow rates from 4 US gpm down to 1 US gpm. The portfolio extends to on-demand water heaters (IWG T-Series tankless, IWG-ES, IWG-HE), aircraft water pumps and transfer pumps (IWG_PWTP), motor-operated valves (FW-MOV), compact water modules (IWG-M1/M2), and the Pre-Select Intelligent Water Quantity Controller, which manages water loading to reduce aircraft weight and emissions. Sub-brands include Pre-Select (weight management aligned to NetZero2050) and Healthy LAV (infrared touchless lavatory).

The business model is predominantly B2B hardware sales on a quote-based pricing model, with revenue from water treatment units, water heaters, pumps and components, and a smaller stream from business aviation MRO services. Go-to-market is enterprise field sales — direct relationships with aircraft manufacturers, completion centers, MROs, and airline operators — supplemented by a global distribution agreement with Satair (Airbus-owned) for the Pre-Select system. Marketing runs through the company's water.aero website, LinkedIn, Instagram, and trade shows including Aircraft Interiors Expo and SkyWard. IWG holds Transport Canada approval and numerous Supplemental Type Certifications in the US and Canada, and was named Supplier of the Year 2024-2025.
