Exchange Rates: Tk (Bangladesh Taka) 1.00=USD0.01447 USD 1.00 = JPY 89.84 (As of June 2010) Preface Recently, it is one of the important issues to secure safe and sufficient water resource all over the world. In March, 2009, “Istanbul Declaration of Heads of States on Water” was adopted at “the 5th World Water Forum” in Istanbul, Republic of Turkey, through a discussion on solutions for various water supply and sanitation issues. In Japan, water programs also have been actively implemented through water business for solutions of domestic and international water issues, such as to promote Public-Private Partnership programs in abroad. In the People's Republic of Bangladesh, assistance on water service, such as mitigation of arsenic pollution of water, construction of water purification facility in cities and improvement of rural water supply, have been implemented with supports of NGOs and donors including JICA. Some of private companies in Japan have already started business on water service sector there. Promotion of this entry of private companies into the water sector is expected with the existing supports by NGOs and implementation agencies of ODA. Under such circumstances, JICA conducted this Preparatory Survey aiming at formulation of the projects by collecting and examining proposals of private sectors on water supply service as “Preparatory Survey on Cooperation Program for the Improvement in Water Supply Services in the People's Republic of Bangladesh”. JICA appointed and dispatched a survey team from Yachiyo Engineering Co., Ltd. to the People's Republic of Bangladesh, in order to mainly examine the possibility and prospect for partnership programs of ODA and private sector and private sector individual program on water service. This report deals with the results of the Preparatory Survey, however, contents of this report do not necessarily reflect the present official opinions of JICA. I hope that this report will contribute to the promotion of the program formulation on water service sector in the People's Republic of Bangladesh, Finally, I wish to express my sincere appreciation to the concerned officials for their close cooperation and assistance extended to the Survey.
