0. Preface

Water supply is the essential social infrastructure to improve public health and living environment.
In 2015, it is estimated that 663 million people worldwide still use unimproved drinking water sources, including unprotected wells and springs and surface water.
To counter this situation, a new global agenda - the Sustainable Development Goals (SDGs) - was unanimously adopted by the member states of the United Nations in 2015.
The agenda included a dedicated goal on water (Goal 6) that aims to “ensure availability and sustainable management of water and sanitation for all.”

Therefore, the Ministry of Health, Labour and Welfare (MHLW) promotes the international contribution and harmonization in water supply sector as one of the five important issues under “Waterworks Vision.” This vision was developed in 2004 to share the understanding of future goals among stakeholders.

International contributions on water supply services (Waterworks Vision)

1. International cooperation in water supply sector

Japan emphasizes the importance of capacity development, such as the development of the organizations, policies, systems, information and data, and human resources of the governments of developing countries as well as water supply utilities, for proper operation and maintenance and management, under the “Water and sanitation broad partnership initiative (WASABI) (2006),” the Japanese policy of Official Development Assistance (ODA) on water and sanitation sector.

Technical cooperation including the dispatch of technical experts and trainings of staff is the measure to realize the above policy. Among bilateral ODA, the details of technical cooperation, grant aid, and government loan are explained hereafter. Most of the projects on international cooperation in water supply sector are conducted by Japan International Cooperation Agency (JICA).

Framework of ODA

1) Technical Cooperation

[1]Dispatch of technical experts

To supply safe and high quality water continuously, both water supply facilities appropriate for each natural and social condition and human resources capable of operation and maintenance of their system, are highly important.

MHLW recommends staff of Japanese water supply utilities and related organizations as technical experts to JICA and sends them to developing countries in order to contribute to enhance central and local human capacity for the better management and administration of water supply services.
