The important factor that makes it possible to increase sewered population rate
in Japan so high and greatly improve water quality of public water bodies in a
short term is technology development. Technology development in Japan is
conducted based on "Five-year Plan for Wastewater System Technology
Development", like sewage works is promoted based on "Five-year Program for
the Sewerage Construction".
Third-Year Plan for Sewerage System Technology Development
In this field, Research and Technology Development Division of Japan Sewage
Works Agency has conducted research and investigation and developed lots
of new technologies.
