1. What’s Japan Global Center for Urban Sanitation (GCUS)

GCUS (Japan Global Center for Urban Sanitation) is a consortium of professional organizations that tackle sewage related issues. In GCUS, experts from the industry, government and the academia are engaged in activities ranging from planning and construction, to management and operation of sewage system. The aim of the consortium is to promote sustainable sewage systems overseas by consolidating know-how and expertise of Japanese sewage-related organizations.

GCUS was set up in 28 April 2009 and the secretariat is based in Tokyo. The activity is supported by the Ministry of Land, Infrastructure and Transport (MLIT), Japan.

2. What we do

Conducting Surveys and Supporting Project Formation

One of the main activities of GCUS is to support project formation that is aimed at solving sewage-related issues for overseas countries. Upon request from a country, GCUS provides information on technological innovations and human resources through field surveys and workshops, and thus functions as an information platform for the international sewage-related issues. Within close coordination with international cooperation groups such as JICA, GCUS also provides technical support in Japan’s specific technical cooperation projects and ODA loans.

Comprehensive management of training programs

GCUS organizes training programs to provide overseas trainees with appropriate lectures that are delivered by a wide variety of professional groups from the industry, government and the academia. These lectures are implemented to the best advantage of trainees.

Development of technical guidelines for recipient countries

GCUS conducts studies to determine what technologies would best suit the needs of a certain country and helps developing technical guidelines for wastewater related facilities, such as advanced treatment facilities and facilities for producing biosolid derived fuels.
Japan has advanced waste treatment facilities capable of removing nitrogen, phosphorus, and salt. Our advanced technologies also include one for converting sewage sludge into energy and another for installing and updating culverts without the need to dig out highly populated urban areas with crowded buildings. Moreover, Japan maintains traditional technologies that treat waste in a simple and effective way, which is as old as the first sewage facilities in Japan. 
Based on these technologies and technical guidelines that have been developed to maintain the facilities, GCUS provides support to overseas countries in order to selects appropriate measures and to develop technical guidelines that can satisfy the needs of each country.

Building international networks

GCUS conducts international activities through a network of overseas sewage-related organizations. With this network, GCUS collects relevant information in order to promote international cooperation in sewage technology, and constantly distributes the latest information on sewage policy and technology.

3. Members

Members of GCUS

GCUS consists of a special council for important advice, a council for controlling policies of each activity, and organizations for coordinating activity. Depending on the country or the theme of activity, we also form activity groups to promote international cooperation in each sewage issue. GCUS is comprised of the following member organizations.

Japan Sewage Works Association (Japanese Only)

Having local public sectors as an official member group, Japan Sewage Works Association conducts research on sewage and promotes clean aquatic environment of river, lake, and ocean by spreading sewage systems.

Sewerage and Wastewater Management Department, City and Regional Development Bureau, Ministry of Land, Infrastructure, Transport and Tourism

In Sewerage and Wastewater Management, Japanese government conducts a variety of sewage-related activities from improvement of combined sewer system to encouragement of international cooperation activities for sewage works industry.

National Institute for Land and Infrastructure Management

National Institute for Land and Infrastructure Management is a national research and experimental institute that performs technological policy research work etc. that must be performed directly by the national government, and is a part of the Ministry of Land, Infrastructure, Transport, and Tourism.

Public Works Research Institute

Independent Administrative Agency Public Works Research Institute is one of Japan’s representing research institutes to efficiently develop public works technologies and quality social capital by conducting research and development concerning public works, technological instruction and distribution of its research results.

Japan Sewage Works Agency

Japan Sewage Works Agency is a special-public organization funded by local governments and the organization keeps advanced engineers in sewerage engineering field.

Japan Institute of Wastewater Engineering Technology

Japan Institute of Wastewater Engineering Technology promotes introduction of new Technologies into sewerage works to make them efficient and smooth, so that they contribute to the improvement of the living environment of the nation, through the research and development of new technologies regarding sewerage.
