Hitachi in Philippines

Water is an essential natural resource on which all life depends. Some 70% of the Earth's surface is covered with water, but only about 0.01% of that represents readily potable water.

To date, Hitachi has delivered some 550 water treatment plants, 2,800 sewage treatment facilities, and 900 monitoring and control systems to locations across Japan. Hitachi offers a diverse range of technologies for water treatment systems and their control and operation. By integrating our advanced IT technologies and store of know-how, we create sophisticated intelligent water systems that are improving water infrastructures around the world.

Hitachi contributes to the acquisition and high-level utilization of water resources in the world. Looking to a global future, Hitachi aims to contribute to the development of a better society by providing reliable technologies and services with superior value.

With over 80 years of expertise in the field of water treatment, Hitachi creates new water regeneration possibilities in the following areas:

  • Water Usage
  • Recycling Water
  • Monitoring Water
  • Protecting Marine
  • Ecosystems

The two main pillars that support Hitachi's core businesses are Research and Development and Monozukuri (Manufacturing) Capabilities. To speed up the cycle of R&D to solutions, joint research with customers, academic institutes as well as R&D Division of Hitachi Group has been actively encouraged. Monozukuri, on the other hand, gives shape to and materializes the results of R&D through the integration of excellent technological capabilities. These are well supported by a wealth of experience and achievements with advanced equipment and superb skills of engineering staff.

Hitachi's connection with water began with the production of water turbines and pumps for hydroelectric power stations in its earliest days. Hitachi Suido was established in 1941 to channel some of the company's industrial water for public water supply. After WWII, it also contributed to, among other things, electrical equipment and pumping stations for water supply and sewage, equipment for irrigation systems and river management.

As pollution issues worsened in the 1960s, Hitachi was one of the first to develop pollutant monitoring and analysis equipment and advanced industrial wastewater treatment systems. Overseas, Hitachi scored points with the production of equipment for water filtration plants and pumping stations to make full use of valuable water.

Similarly, Hitachi has participated in various action programs for the project "Team Water Japan" which was led by the government in 2009.



  • Ishioka Daiichi Power Plant in Ibaraki Prefecture is a hydroelectric power station built using reinforced concrete. It is Japan's first power generating facility.
  • Hitachi delivered three 10,000HP water turbines to the Iwamuro Power Station of Tone Electric Power (now TEPCO). The Toyo Keizai news magazine sung the praises of Hitachi: "At a tim when no Japanese company could even make a 1,000HP class water turbine, it's remarkable that Hitachi was able to complete a 10,000HP version."

  • The Tsukudajima Engineering Works, which became the Kameido Works when Hitachi was reorganized in 1918, manufactured items such as centrifugal pumps, hoisting equipment and cranes for the Hitachi mine.
  • Learning from the failure of the Natsuigawa Power Station, which was damaged in 1916, Hitachi made a horizontal-axle-type Francis water turbine generator¬†(1,300kW) for the Nikko Daiichi Power Station run by Shimotsuke Denryoku.

Case Studies

Sewage Treatment Plant for Malaysia

As population increases rapidly, sanitation situation in the city and suburbs of Kuala Lumpur deteriorated. With the help of advanced sewage treatment technology from Hitachi Plant, existing oxidation ponds are now modified into modern sewage treatment facilities, allowing now cleaner treated water can be discharge into rivers.


Stories of Technology "Pump" - Hitachi

Hitachi's water environment operations are a key business area in its social innovation sector. For more than a hundred years, the Hitachi Group has manufactured and supplied numerous pumps for irrigation, drinking water and sewage, wastewater and electric power generation. In this way it is contributing to the advancement of global water business through a wide range of projects, both in Japan and worldwide. This video shows the latest technology and examples of projects in this sector.
