Original Engineering Consultants Co., Ltd., has been established in January 1962. As a consulting firm specialized in the fields of water supply, sewerage works, sanitation and solid waste treatment, OEC has accumulated vast experience of consulting services such as investigation, planning, detailed design and construction supervision in these fields. OEC also has focused on using computerizing engineering system to improve the efficiency of designing and calculation works since early days of its establishment.
Because of the fact OEC has developed such variety of consulting service systems and software for municipality clients by itself and outsourcing, it made us much stronger in the professional civil engineering consulting fields such as sewer main planning and design, urban runoff control, flood prevention plan, combined sewer overflow control, asset geographical mapping system, structural calculation and so on. OECfs unique characteristic is that OEC can be neutral to any associations, contractors and manufacturers, because OEC has not only established by the founder, Osamu Suga without getting investment from those parties or firms, but its stock has been mainly held by the founder and its family company.
As far as overseas business is concerned, OEC launched its project to draw up a master plan of sewerage systems in Seoul City, the Republic Korea in 1977.Since then, OEC has undertaken many projects of water supply and sanitation, financed by World Bank, Asian Development Bank, the International Bank for Reconstruction and Development, Overseas Economic Assistance Fund, Japan International Cooperation Agency and foreign local municipalities or local entities. OEC has been expanding more than twenty domestic offices in Japan and one overseas office in Hanoi, Vietnam. Ministry of Economy, Trade and Industry (METI) projects that a global water infrastructure business market will soar from USD 360 billion in 2007 to USD 870 billion in 2025. In view of this promising market, Japanese government has been preparing several measures to help Japanese player's enter into the water infrastructure business abroad. One of the most important measures taken of late is public financial backing for PPP project making and forming in foreign countries. OEC is a member ofgPPP Council for Overseas Water Infrastructureh, organized by Japanese government. The Council is composed of more than 100 members including Japanese local municipalities and Japanese private companies that get interested in such business. With abundant experiences and achievements accumulated in both Japan and overseas, OEC joins some consortiums and support them by respectively conducting feasibility studies for formulating water infrastructure projects based on PPP.
