The Microflush-Biofil(MB) toilet system, a prototype marriage of a macroorganism enhanced aerobic digester and an innovative valve that flushes on just 150 cc of water has proven to be an effective sanitation solution for developing world tropical communities. This paper examines the sustainable elements of this technology. We present the approach of the Ghana Sustainable Aid Project in readying the technology for a decentralized approach in moving to a global scale. The challenges and opportunities associated with such an ambitious plan.

This paper is occasioned by the WIT inauguration of a new conference on Water and Society. It reviews some of the connections between water and sanitation (WATSAN) and human dignity, security, morbidity and mortality, education and community development. It draws on the authors' experiences in Ghana and published findings related to Millennium Development Goal (MDG) studies and relevant policy analysis efforts. The application of sustainable design and problem solving to help advance the MDGs through the design and introduction of an innovative toilet system is discussed.
