About GWRA

A Message from the President


This association was established in November 2008 as a limited liability partnership by gathering the concerned companies together and collaborating with the government and academia. The purpose of the establishment was to expand the water operation business to abroad by the water recycle system with the technology and know-how that our country possesses. In February 2012, the organization was reformed as the general incorporated association from its predecessor. During the said period and in the meantime, various problems have emerged in the world, such as an increase in population, water resource problems due to climate change, and an increase in water demand due to improvement in living standards, and as a result, serious water shortages in the future became significant concerns. In addition, the importance of water is focused on in the SDGs (Sustainable Development Goals) adopted at the United Nations Summit in the year of 2015 as “to ensure availability and sustainable management of water and sanitation of all”. Specifically, it is stated by 2030 that we will, “(1) achieve universal and equitable access to safe and affordable drinking water for all, (2) achieve access to adequate and equitable sanitation and hygiene for all and end open defecation, (3) improve water quality by reducing pollution, eliminating dumping and minimizing release of hazardous chemicals and materials, halving the proportion of untreated wastewater and substantially increasing recycling and safe reuse globally”, It is expected globally that the opportunities will increase in the future such as supply of tap water, sewage treatment and use-expansion of reuse water.

To achieve the goal of SDGs, we think it is necessary not only to develop sufficiently the water purification plants and the sewage treatment plants for large cities but also to facilitate a utilization of reclaimed water. We believe that, it is also necessary to develop the infrastructures for large city’s neighboring areas and local rural cities, even more for the undeveloped areas. As one of countermeasures, on-site treatment (decentralized water treatment) with smaller cost burden will be introduced instead of off-site treatment which is costly for maintenance of piping network. It is a system enabling us to collectively manage by using IoT / ICT and therefore we anticipate that such systems will increase. This system integrates management of water sources, various water treatment information, and even end user information, unified management, cost saving and at the same time safety and security can be obtained. This is one of the fields that our country is proud of and therefore we believe Japan must lead.

By making use of private association’s strengths in various industries and enhancing collaboration with the government and academia from now on, we will make further efforts to develop the water business, in addition generating projects which contribute to the development of countries and regions.

We kindly request all of you to let us have your continued support.
