  • Project Lead(s): Walter Gibson

    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.
