Formulation of a Project That Reflects Stakeholder Opinions
Based on the need for water supply infrastructure development from the Government of Cambodia and requests for Japan’s expertise in water supply service, JICS gathered information on the intentions of Japanese companies seeking to expand overseas over the medium to long term as well as knowledge from local government authorities in Japan. This was applied to the formulation of a project that is sustainable over the longer term while gathering the opinions of the Government of Cambodia and other stakeholders.
When the project was formed, the Government of Cambodia held several project brief-ing sessions with support from the consultant for community residents to explain the social and environmental impacts of the project, the timing of the start of water supply, water supply rates and the application process, and to answer questions from residents. As a result of these sessions, we made adjustments and developed appropriate project plans taking the residents’ opinions and consensus into account.

Proposal and Close Consultation on the Introduction of the Most Suitable Bidding Method
JICS proposed to the Government of Cambodia the application of a ”design, construction, maintenance and operation collectively contract method,” which is unprecedented in conventional Grant Aid, as the optimal bidding method for selecting a consortium of Japanese companies to take on this project. To obtain sufficient understanding from the Government of Cambodia, JICS worked with the consultant to explain and discuss the project many times, and prepared the bid documents. The facilities completed through these efforts were highly evaluated by the Director General in charge at the time of completion.

Stakeholders Take On the Challenge of Improving Access to Safe Drinking Water
The water supply facilities were completed in April 2022 and the consortium of Japanese companies has started supplying drinking water services to the Cambodian people. We would like to reiterate our deepest appreciation to the Japanese companies awarded this project, led by Kubota Construction, for their steady continuation of construction work even under the extremely difficult cicumstances of the COVID-19 pandemic. Furthermore, the Secretary of State of the Government of Cambodia personally participated in the meetings from the very beginning and showed tremendous initiative to improve the access to safe drinking water. The earnest passion of the Government of Cambodia, which remained consistent from start to finish, has led to the operation of the new water supply facilities. We will continue to watch over the facilities so that they will be used widely and for a long time by residents.
