Blue Diversion Toilet has been designed as part of the “Reinvent the Toilet Challenge” sponsored by Bill and Melinda Gates Foundation. There are more than 2.5 billion people worldwide that still have to use unsafe toilets or defecate in the open, this lack of adequate sanitation can cause severe diarrhea and end up kills more than 1.5 million people each year. This problem is also a major threat to our environment. The brief of the challenge was to design sustainable and affordable sanitation services for urban slum neighborhoods in low-income countries, a toilet that covers all resources and operates grid-free where the total cost won’t exceed $0.05/person/day.
This concept toilet is an innovative sanitation system that is eco-friendly with strong financial and social benefits. The design is appealing and of course, it is affordable and great solution for washers as well as wipers. Each unit has been designed for industrialized manufacturing, providing sustainable sanitation value chain with zero discharge. It will become the center piece of market-based approach to sanitation, it would attract many profit-seeking entrepreneurs.

The main system of this sanitation service is Blue Diversion Toilet. It works by separating undiluted urine, feces, and used flush-and-wash water. By separating these streams at source, enabling efficient resource recovery. All used water is treated in a multi-barrier treatment system and reused on-site. All urine and feces are recovered off-site at a community scale Resource Recovery Plant (RRP) where fertilizers are produced.
