We are the world’s leading provider of aircraft water treatment and innovative water system solutions.

Our extensive experience in ultraviolet light technology and leading edge water systems design have positioned IWG as the world leader in aircraft water treatment.

Since 1982, hundreds of corporate, VIP, and military transport operators have chosen an International Water-Guard (IWG) solution to the problem of onboard water quality. Major business jet manufacturers now offer IWG’s water treatment units as either a standard factory installation, or as a customer option. In all, more than 1,000 of IWG’s units have been factory-installed or retrofitted to aircraft worldwide.

IWG also offers a full aircraft water system solution in the form of its patented circulating potable water system (C-PWS™). Weight, space, and maintenance downtime are all reduced, while performance and water quality increase - all with the elimination of in-flight freezing. These benefits have all been proven in service conditions on multiple types over many years. Operating from our headquarters near Vancouver, British Columbia, our team of aviation water professionals continues to develop new and better solutions to the issues surrounding onboard water quality.
