Hitachi contributes to the acquisition and high-level utilization of water resources in the world. Looking to a global future, Hitachi Plant Technologies (HPT) 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, HPT creates new water regeneration possibilities in the following areas:
History
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.
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.” 
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.
