Our intelligent water system contributes to society by creating an optimized water cycle for as many people as possible.
In the 21st century, water shortages and pollution are expected to become more acute as populations grow and concentrate in cities. There is a worldwide need for social infrastructures that conserve and use limited water resources and create sustainable living environments.
Based on: IWMI Annual Report 2006/2007(International Water Management Institute)
Island of Malé in the Republic of the Maldives
In fiscal 2010, we set up the Water Environment Solution Division to increase deployment of our intelligent water system. We are working on a water recycling project in Dubai to improve water quality that has deteriorated due to population growth and a desalination project in India to provide a stable water supply for industrial use from desalinated seawater. Other projects include water and sewage management systems and deep seawater systems for air conditioning to reduce CO2 emissions in the Maldives, as well as solar-powered desalination equipment in Abu Dhabi to protect rare desert animals.
We will work to expand our business in China, Southeast Asia, and emerging nations. In developed countries, we will further advance systems that optimize intelligent water cycles.
Hitachi's Worldwide Water Environment Solutions
|Project||Main Developments||Hitachi Group Involvement|
|Water recycling in Dubai (UAE)||August 2008
Hi Star Water Solutions LLS established as a joint-venture company
Water recycling business launched
|An urban development boom in Dubai has caused social problems such as deteriorating water quality. Hitachi built a plant using membrane technology to treat wastewater. At the plant, a business has been launched that supplies inexpensive treated water to nearby factories for industrial use.|
|Solar-powered desalination units in Abu Dhabi (UAE)||Sept. 2009
First unit supplied
All 15 units supplied
|We participated in a project to protect the endangered Arabian oryx and other desert-dwelling animals. Hitachi's solar-powered desalination units convert highly saline well water into fresh water for desert animals.|
|Seawater desalination project in Dahej, Gujarat, India||Dec. 2009
Japan-India Summit agreement
Joint development contract
Water supply agreement
|We are helping to build one of the largest seawater desalination plants in Asia, part of an agreement between the governments of Japan and India on smart community development. The plant is expected to provide a stable supply of industrial water over 30 years (including construction) at a rate of 336,000 m3 per day.|
|Water and sewage business in the Maldives||Jan. 2010
Hitachi acquired 20% of shares in Malé Water and Sewerage Company Pvt. Ltd.
|We installed approximately 200 seawater desalination units, an information management system for pipe network in the island of Malé and a water-cooled air conditioning system using deep-sea water in airports and buildings, enabling a reduction of 12,450 tonnes of CO2 emissions per year (estimate).|
In Japan, we have supplied equipment and systems for 550 domestic water treatment plants and 2,800 sewage treatment plants, in addition to 900 monitoring and control systems. As well, we participate in water-related projects in 40 countries. Our intelligent water system contributes to society by creating an optimized water cycle for as many people as possible. We achieve this by coordinating our infrastructure technologies—water and sewage treatment, industrial wastewater treatment, desalination, and water recycling technologies—with information management and control systems to optimize water use.
