01Offering total solutions in water treatment and natural resources development
Drico Co., Ltd. plays the central role in the ASAHI YUKIZAI GROUP’s water treatment and natural
resources development business. We have amassed advanced drilling technologies, subterranean
survey technologies, and a vast amount of data in the course of more than 70 years. We leverage
these strengths in a diverse range of business operations. In our water treatment business, for
example, these include the circulation and reuse of wastewater in commercial buildings and other
facilities, and water and sewer services. We also develop underground resources such as wells,
geothermal heat and hot springs. In addition to developing environmental chemicals required in
the water treatment process, we also provide the maintenance that process entails. We seek to
create water with value, and we make a positive contribution to the global environment and
people’s lives and lifestyles.
02Playing an active role in various aspects of society, from wastewater treatment
to geothermal power
We possess advanced expertise in water treatment, and our equipment is used for such purposes as
recycling gray water in Haneda Airport terminal buildings and Tokyo Midtown, and treating
factory wastewater in a diverse range of industries, such as glass and foodstuffs. We also have
an extensive track record in public water and sewage facilities throughout Japan. In our
resource development business, meanwhile, we have excavated more than 300 hot springs
nationwide, including Ikaho Onsen (Gunma Prefecture) and Phoenix Seagaia Resort (Miyazaki
Prefecture). We can proudly say that we are number one in Japan, both in terms of the number of
wells drilled and in their combined length, which is now more than 350 km. The world has high
hopes of geothermal power as a renewable energy, and we are very highly regarded for the diverse
drilling technologies we use to excavate the exploration wells, production wells and injection
wells that are required for geothermal power plants.
