Improved sanitation still remains an important challenge to the Millen-nium Development Goals, which aim to greatly alleviate conditions for the World’s impoverished people. In ma-ny dense urban areas there already exists sanitation facilities, but they can be neglected and poorly main-tained without a central disposal site. The results are sanitation systems that fail to safely dispose of sanita-tion sludge because of inadequate or inefficient infrastructure. This endan-gers public health and pollutes the environment. A recent UN report estimates 15% of basic sanitation fa-cilities lack proper separation of hu-man waste from human contact. The consequences are sanitation facilities become a transmitter of infectious diseases and environmental pollu-tion, a direct contradiction of their original purpose.
