Abstract

It was the 1970’s when we noticed the problem relating to human waste treatment in mountain districts by occurrence of eutrophication of the Oze District. Then in the 1990s, there was a rising concern about the human waste treatment again when Escherichia coli was detected in rivers which issue from the mountain districts including the Southern Alps. Backed by these problems, development and introduction of non-discharge human-waste treatment equipment which was usable even at sites where the infrastructure was not constructed were promoted. As diverse techniques of human waste treatment were required depending on the condition of a location, the Ministry of the Environment established in 2003 the division of treatment technologies for human waste in mountain district in “The Pilot Project of Environmental Technology Verification of Japan” to verify objectively the performance of the technologies by third parties. Thus, the Ministry has exerted their efforts for dissemination of these technologies.<BR>Five years have passed since this verification project was introduced, and it will be a full-fledged operation in 2008. Hitherto, verification methods of technologies and improvement of the verification system were mainly examined. It would be a mature time to make the project beneficial to users as well.
