Prototype Off-Grid Sanitation System Debuts in India

In India alone, diarrheal disease is estimated to kill one child nearly every minute—a symptom of having almost 600 million people resort to open defecation every day. Worldwide, that number is 2.5 billion.
For the past several years, researchers at Duke University have been working with RTI International and Colorado State University in an attempt to “reinvent the toilet” to help solve the world’s sanitation crisis. And that’s not their language; the phrase was coined by The Bill and Melinda Gates Foundation, which launched the program that funds 13 separate projects worldwide in 2012.
Duke’s part in the project, led by Jeff Glass, professor of electrical and computer engineering, focuses on the basic science required to develop efficient disinfection techniques for the liquid waste. The end goal is a self-contained, zero-energy-, zero-water-use system that can bring safe, affordable sanitation to those who need it, while introducing a sustainable energy technology.
The project recently reached a milestone with the opening of the first test facility at the Centre for Environmental Planning and Technology University (CEPT University) in Ahmedabad, India.
"CEPT University is an excellent location for our next phase of user design and feedback studies, and a good platform for performance testing under controlled conditions," said Myles Elledge, senior director for global development and strategy at RTI. "CEPT's expertise in architecture, building science and urban environmental planning makes the campus a great host and research collaborator for our next round of prototype development in India."
