Overview: The 21st century has been called the "water century" because of problems such as water pollution and water shortages in various parts of the world. By supplying a variety of products associated with the protection of water resources, Hitachi has been playing a part in helping solve these problems. In addition to the supply of products and systems, Hitachi is promoting its intelligent water system concept which aims to optimize the water cycle across cities or entire catchments, undertaking actions targeted at coordinating the operation of water treatment with information and control systems. New initiatives by Hitachi based on this concept and aimed at ecosystem protection include protection of endangered species by providing water supplies in desert regions and protection of marine ecosystems by treating ship ballast water or removing red tide algae.

OVERVIEW: Hitachi is active in the fields of plant, information, and operation and maintenance services for essential services (including electricity, gas, and water), transport (including rail and road), and other social infrastructure. With the aim of participating in the construction of the next generation of environmentally conscious cities in Japan and around the world (smart urban development), Hitachi established a Smart City Business Management Division in April 2010 and a Water Environment Solutions Division in June 2010 to strengthen its activities aimed at meeting the current need for innovation in social infrastructure. There is a rising level of global activity in the area of demonstrations and other urban development projects such as eco-cities and Hitachi is participating in these in ways that include product development and increasing the added-value of its products by applying advanced technology in the field. In addition to facilitating innovation in social infrastructure, Hitachi is also working on feasibility studies in conjunction with government policy objectives in which it puts an emphasis on initiatives that take account of the individual circumstances of each city or community.

Japan is rich in water resources with little experience of water shortages. Internationally, however, examples can be seen both of locations where lack of water is a physical phenomenon and where it is an economic one, and it is predicted that water shortages will become more severe as populations rise and become more concentrated in the urban areas. Effective ways of supplying water to afflicted cities include production of water by seawater desalination and use of recycled water, and there is a need to manage the overall circulation of water around the city efficiently. To provide smart cities with water infrastructure systems, Hitachi is promoting its intelligent water system concept for integrating water treatment systems with information and control systems for the efficient utilization of recycled water.
