Mission and Vision

To date, GlobalMedic has distributed nearly 45,000 Rainfresh units throughout the world, in response to large-scale disasters and complex emergencies.

Innovation Description

The Rainfresh Household Water Purification Unit is a simple, low-tech solution that will provide an entire family with clean drinking water for a year. It can purify water from virtually any source, protecting people’s health during an immensely vulnerable situation. It will also allow families to save money on bottled water, keeping funds for other necessities like food, medicine and shelter as they recover.
How does your innovation work?
Each Rainfresh unit consists of two food-grade plastic buckets and lids, three or four ceramic filters, a spigot, a cleaning pad, a gauge, and instructional material. The two buckets sit one on top of the other: one for the untreated water and the other for safe drinking water. The upper container holds untreated water and houses the ceramic cartridges through which the water flows under gravity. As water passes through the ceramic cartridges, pathogenic bacteria (e.g. E. Coli) and protozoan cysts (e.g. Cryptosporidium and Giardia) are killed, and sediment and suspended matter down to 0.3 micron (1 micron = 1/1000 mm) are trapped. Safe drinking water passes through. Clean water then collects in the bottom water container. A spigot dispenses the treated water for use in a sanitary way. The unit purifies three litres per hour of clean drinking water – enough to support the daily needs of an entire family. When the ceramic cartridges get plugged with dirt, they can be easily cleaned by scrubbing the surface of the cartridge using a scrub pad, which is included with the unit. A cartridge gauge, also included, is used after every cleaning to check whether the cartridge diameter remains a functional size. When the gauge diameter equals or exceeds the diameter of the cartridge, the cartridges need replacement. These Rainfresh units will provide a point of use solution for families to treat, purify, and store clean drinking water. The unit will prevent vulnerable populations from being afflicted by water borne disease such as cholera. Rainfresh goes beyond typical emergency water filtration systems. While most emergency household filters assist families in the short term, Rainfresh provides purified drinking water well beyond the emergency phase of a disaster, and into the recovery and rebuilding phase. As families work to rebuild their lives, Rainfresh is there to keep them healthy and safe for a full year. Rainfresh is also extremely versatile and can be used in almost any disaster setting or complex emergency. The unit is lightweight and easily portable. Filters from Canada can be shipped all over the world, and the accompanying bucket can be purchased and prepared in-country. This not only supports the local economy, but also supports local workers who can be hired to assemble the units. They are easy to assemble and maintain, and extremely cost affective.

Competitive Advantage

When a disaster strikes, people who have been affected are at great risk of contracting deadly water-borne illnesses. Disasters such as typhoons, floods and earthquakes often destroy water treatment and distribution systems in cities, as well as lead to contamination of water sources in rural areas. Providing people with clean drinking water is of vital importance. The Rainfresh Household Water Purification Unit is a simple, low-tech solution that will provide an entire family with clean drinking water for a year. It can purify water from virtually any source, protecting people’s health during an immensely vulnerable situation. It will also allow families to save money on bottled water, keeping funds for other necessities like food, medicine and shelter as they recover.
