Water, Sanitation, and Hygiene

Joanna Bichsel of Kasha in Rwanda will adapt their mobile ecommerce platform to enable women in Kenya to confidentially order health products such as contraceptives and sanitary pads by mobile phone. There are many social barriers preventing women in developing countries from accessing products at health clinics. Their platform, Kasha, requires only a mobile phone to order and pay for products that are then delivered to local pick-up points. They have successfully implemented Kasha in Rwanda and will now perform a pilot study in several counties in Kenya.

The innovators are tackling the global problem of unsafe drinking water, which kills millions of people per year, especially young children. The proposed solution of UpWater, is not just a water-treatment technology. UpWater endeavors to give communities a jumpstart on their paths toward long-term health betterment, by integrating appropriate innovations, social transformation and sustainable business models.

Mike Allen of Plymouth Marine Laboratory in the United Kingdom proposes to develop a low cost, vortex-based bioreactor that is driven by hand or a bicycle to separate fecal matter from waste water and at the same time introduce bactericidal agents to decontaminate the waste for recycling or safe disposal. In Phase I they designed and built a desk-top vortex bioreactor to test different biocidal agents for their ability to kill bacteria, and to be physically immobilized to enable long term use.

Steven Dentel of the University of Delaware in the U.S. will test the ability of a low-cost polymeric breathable membrane liner to accelerate the drying and disinfection of fecal waste in pit latrines, while protecting surrounding groundwater from being contaminated with pathogens and chemicals. Breathable membranes are hydrophobic, allowing only air or water vapor to pass through them.

Marcos Fioravanti and Chris Canaday of Fundación In Terris in Ecuador will develop an easy-to-use urine-diverting dry toilet that uses a pedal to "flush" feces into a pipe and mix the waste with dry material for faster composting. Following toilet use, pushing the pedal turns an auger in the pipe, withdrawing the waste to eliminate odors and to enable safe sanitation, after which it can be used as fertilizer. In Phase I, they designed, built and laboratory-tested three prototypes with varying designs.

Sarah van Boekhout and the team of WaterSHED in Cambodia will further catalyze the water, sanitation and hygiene (WASH) market by developing a women's mentorship network and a special marketing program in order to improve the productivity and decision-making power of women in rural Cambodia. This project focuses on the success of female entrepreneurs in the market for WASH products and sevices.

Farhana Sultana of the International Centre for Diarrhoeal Disease Research in Bangladesh will develop and test an approach to bring together all members of a community to improve the health of menstruating girls and motivate them to attend school. Many girls in low-income countries avoid going to school when they are on their period because of poor facilities, lack of sanitation products and support, and social marginalization, which severely affects overall academic performance.

Gary Foutch and AJ Johannes of Oklahoma State University in the U.S. propose to develop a small-scale device in which an auger forces feces and other solid wastes device through a die that results in high temperatures and pressure that dewaters the waste and destroys microorganisms. The device could reduce odor, insects, surface and ground water contamination, and the associated spread of diseases.

Robert Borden of North Carolina State University in the U.S. will develop an inexpensive method to efficiently and hygienically remove human waste from cesspits. Borden will modify readily available gasoline powered augers and PVC pipes to operate as a progressive cavity pump for filling drums or other easily transported containers. In Phase I, Borden produced and tested an inexpensive machine that could effectively remove medium- to high-viscosity waste from a range of pits with different accessibilities in South Africa.
