The Sewerage Systems have been
	increasingly important to accomplish the
	preservation of clean water and comfortable
	life environment. Since technologies
	regarding Sewerage Systems have been
	renovated constantly and rapidly, effective
	and rational introduction of newly developed
	technologies to actual sewerage systems in
	planning, designing, constructing and
	managing stage, yields remarkable r
	eduction of construction and maintenance
	cost, upgrading of sewerage facilities and
	improvements of maintenance and operation	Main Office of R&D Division and
		Training Division of JS in Toda City
	In this regard, the Research and Technology Development Division of Japan Sewage
	Works Agency as a support organization for local governments develops new
	technologies relating sewerage systems, implements test study, and promotes the
	practical use and encourages broad use of developed technologies.
	The range of test study covers the whole fields of sewage works; Sewage Collection
	System, Wastewater Treatment, Sludge Treatment, Reuse and Effective Use of
	Sewage and Sewerage Facilities, Maintenance and Operation, Conservation of
	Surrounding Environment, Design and Construction, etc.
	The main roles of JS R&D Division is as follows
	JS R&D Division conducts new technology
	development regarding sewerage systems.
	Experiment and Research consists of proper
	research in dependently conducted by JS,
	entrusted research by central or local
	governments, and joint research with other
	organizations or private companies. These
	researches and test studies are performed
	at main office of R&D Division located in	Experimental Field in Mouka City
	Toda City and in Experiment Fields in Mouka
	City. To progress the proper research and
	joint research effectiverly and efficiently,
	the validities of reserch topics regarding
	reserch implementation measures,
	results of research, etc. are evaluated
	regularly. The main subjects of R&D
	Divisionin F.Y. 2004 are asfollows.
		Experimental Field in Mouka City
	On introduction of newly developed
	technology to actual projects, these new
	technologies should be evaluated
	objectively and fairly with regard to its
	performance, points to notice in designs
	and/or maintenance stages, etc. To carry
	out this kind of evaluation, JS organized
	the Technology Evaluation Committee as
	an advisory organization in F.Y. 1974. The
	Committee consists of academy experts
	and well experienced engineers of central
	and local governments. The evaluated	Technology Evaluation Committee
	technologies by the committee are as
	follows.
	The outcome of technology development and test study has been introduced
	in web page and published in bulletin report, annual report, and e-mail
	newsletter. Also, the outcome has been released in the conference,
	magazines, etc.
	After newly developed technology are
	evaluated by the Technology Evaluation
	Committee, these new technologies are
	registered on the list of new technologies,
	and JS engineers decide to introduce
	technologies, and JS engineers decide to
	introduce the technology to local
	governments based on the each site's
	condition. Then, two or three years later
	from the introduction, follow-up survey is
	conducted and the newly developed and
	introduced technology is reevaluated by
	the Committee based on the data collected
	by follow-up survey. Finally, in accordance
	with the result of reevaluation, design
	standards or maintenance manual would be
	improved, and introduced technology would
	be upgraded.
		Encouraging Introduction
		of NewTechnology
	Since the establishment of JS, R&D Division has
	developed and evaluated lots of new technologies and promoted the practical
	use of newly developed technologies, and the outcome of R&D Division has
	been widely applied to the construction or maintenance of sewerage systems.
	Hereafter, JS R&D Division as support organization for local governments
	continues to promote the technology development to preserve clean water and
	comfortable life environment.
