Access to clean water is a key determinant of public health and current purification methods are energy intensive and thus impractical for low income regions. This project will develop a scalable energy-efficient water purification method based on ion concentration polarization at the interface between micro scale channels and planar nanoporous membranes.

Two and a half billion people worldwide lack access to proper sanitation. Three million of them are in Lima, Peru’s capital. Although poor sanitation in slums also affects men, it is women in the slums who suffer the greatest burden, as they are unable to relieve themselves discreetly due to a variety of factors, including their modesty and susceptibility to sexual attacks. This is in addition to other health risks, especially diarrhea, which kills 1.5 million children under five each year. Poor sanitation also contributes to developmental delays in children through infections.

A new technology, proven in the lab and now in field tests in rural India, uses composting worms to degrade fecal solids and a filtration system to treat the liquid effluent. The technology takes half the space of a twin pit latrine, treats fecal waste effectively, requires less frequent emptying and costs about the same to install. The new system links to a pour-flush toilet with a water seal, thus providing a hygienic environment, free of smells and flies.

High equipment costs prohibit the appropriate incineration and safe disposal of medical waste for many hospitals in resource-poor countries, leading to contaminated supplies and sharps being landfilled or dumped on roadsides, infecting animals and people with agents that can lead to sepsis, hepatitis and HIV.  A modular, low-cost incineration system developed by this project will be locally built and adapted to meet hospital waste disposal needs.

The project intends to use organic waste for production of biogas for cooking or electricity generation. Uncontrolled waste in urban slums that is often washed into drainage channels causing flooding and breeding sites for waterborne diseases and mosquitoes will be used as a resource.

An increasing number of people are living on water and without access to sanitation. Diarrheal incidence and child mortality are higher in floating villages than in land communities. The HandyPod is an innovative treatment system, using two-stage sequestration and treatment that includes aquatic plants, that is addressing the challenge of providing effective sanitation to floating communities. Technical support, marketing and sales training are provided to entrepreneurs who can scale up access to sanitation.
