- Abstract:
- The non-sewered sanitation system(NSSS) refer to sanitation systems that are not connected to a networked sewer. The system can collect, transport, and treat feces and other specific inputs independently. The NSSS have developed different standardized modes of standard certification, environmental technology verification and ecological product labeling. The origin of NSSS was reviewed and the NSSS certification standard of ISO and the corresponding processes were summarized. The NSSS standards in the United States and Europe were also reviewed, which include both general and special standards. Additionally, the verification standard of feces treatment technology used in natural areas of Japan was introduced, which can be applied to standardize and promote newly developed non-sewered sanitation technologies. Standards related to NSSS in the field of tourism, environmental industry and rural sewerage of China were also outlined. The paper suggests strengthening coordination among different NSSS standards and their integration with other existing standards. Furthermore, it proposes the establishment of a comprehensive NSSS standard system in China that covers various application fields, process types, and mature products under a general standards framework.
