Ministry of Land Infrastructure and Transport, MLIT, revised the second five-year
plan for sewerage system technology development and launched the third five
-year plan in May 2004 A five-year plan for sewerage system technology
development was first made in 1994 and it was revised in 2000. In the new
five-year plan, which was formulated in 2004, main technology development
items of the former five-year plan were reviewed, and the contents and promotion
measures for new technology development were illustrated.
In the new five-year plan, main goals which future technologies for sewerage
systems should accomplish, formulated into five categories as follows based on
the technology development strategy in Technology Basic Plan of MLIT.
I. Safety and Secure Life
II. Fine and Sustainable National Land Development
III. Comfortable and Low Public Charge Life
IV. Enhancement of International Contribution and Accomplishment of Dynamic
Society
V. The Society that Everyone can Realize the Participation of Citizens to the
Project
For these main goals, 32 items of technology development were set up and
contents, targets, and necessity of new technology development in the next five
years were explained for each item.  The concept of five major goals (categories)
and the 32 technology development items are shown in following web page.
Outline of the Third five-Year Plan for Sewerage System
Technology Development
In new plan, following 6 new items were newly set up.
(1) Planning measures for flood control from the viewpoint of watershed
management
(6) Introduction of economical measures on elimination of pollutant load
(8) Establishment of consolidated database for water environment
(17) Optimization technique for organic waste in the society
(19) Upgrading technologies of sewerage systems correspond to the change
of urban structure
(25) Technologies to reduce life cycle cost of sewerage systems
(Note)
The above number indicates the item number for technology development in the
table "Outline of the Third Five-year Plan for Sewerage System Technology
Development".
In this plan, the contents of technology development which are conducted by
central government are detailed specifically to clarify the role of central
government. These indicated researches and technology developments in new
plan are mainly conducted by MLIT National Institute for Land and Infrastructure
Management, Incorporated Administrative Agency Public Works Research
Institute, and Japan Sewage Works Agency.
For participation of private company, new joint research measures, financial
support for researches and technology developments which are conducted
by private companies, establishment of database for newly developed
technologies by private companies, etc. are also proposed.
