100 Selected Revived Waters甦る水１００選
About this collection
The "Old Sewerage Law," enacted in 1900 (Meiji 33), laid the foundation for the modern sewerage system. The "100 Selected Revived Waters" project was conducted by the Ministry of Land, Infrastructure, Transport and Tourism's Urban and Regional Development Bureau as a commemorative event marking the 100th anniversary of this law's enforcement. It selected 81 rivers, lakes, and other sites nationwide where water environments have been successfully preserved or restored. Sewerage systems are indispensable for achieving comfortable living environments and clean water environments, but they are generally out of public view, and there has been a lack of awareness about the effects and roles of sewerage development. The "100 Selected Revived Waters" project focuses on the creativity and efforts of local governments to deepen public understanding of the necessity of sewerage development. Selection criteria include cases where sewerage development has preserved or restored water environments, cases where treated water discharge has preserved or restored water environments, and cases where sewerage projects have created water environments such as streams.
