Cambodia Project (JICA)
Concerned Development Issues

The main survey site, Kralanh in Siem Reap Province, is an area where sewage and wastewater treatment is a major concern and is the area where the proposed company, Reed NET Co., Ltd. has been conducting a series of site surveys together with the Department of Public Works and Transport (DPWT) in Siem Reap since 2016. Local hearings with residents have already raised the following urgent issues.

  • Inundation during the rainy season
  • Bad odor problem
  • IInfectious diseases during the rainy season

Solutions to the above issues will be provided by the proposed company as follows.

(1) Improvement of Water Pollution

With the spread of low-cost and low-energy artificial wetland technology, it is possible to improve the water environment in Cambodia by treating village drainage and the like.

(2) Improvement of Living Environment, Prevention of Infectious Diseases and Health Damage

Utilization of artificial wetland technology for village drainage can improve the living environment of local residents, especially their sanitary condition, and prevent infectious diseases and health damage.

(3) Human Resource Development and Employment Creation for Wastewater Treatment Engineers

With the spread of artificial wetland technology, it is possible to transfer technology and train human resources as a wastewater treatment engineer including invitation of Cambodian engineers to Japan.

At the same time, a business model that packages from research, design and construction to operation and maintenance of the artificial lands will be established and employment creation in Cambodia will also be made.
