Water Treatment & Natural Resources Development

Water Treatment & Natural Resources Development We will continue to contribute to society through water-related business.

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.

03Promoting the eco-friendly and pleasing use of water

Systems to reuse gray water in locations such as commercial buildings make effective use of water resources and also help to cut water bills. In factories, wastewater can be reused, or purified so that it can be released into a public body of water. We offer equipment that can provide the optimum water quality for the purpose to which industrial water will be put. We provide a multi-angled response to our customers needs with regard to water and resources, drawing upon our three specialist areas: water treatment, proprietary environmental chemicals such as those we have developed to improve microbial wastewater treatment or that utilize deodorizers or the like, and underground resource development utilizing our advanced drilling technologies. We offer solutions that take both economic and environmental considerations into account.

04Building systems with equipment that is always safe and reliable


Our job is not over when we deliver equipment to the customer. We set up maintenance and repair services, and immediate response services, for the equipment we have designed and installed, in places such as gray water plants, water-purification tanks, industrial wastewater treatment systems, and hot spring facilities. We make every effort to ensure that our equipment is always safe and reliable, and that our customers will continue to use our products and services. Water and similar resources come from the natural world. We purify them and return them to nature. ASAHI YUKIZAI will draw upon our cutting-edge technologies and abundant experience, and work alongside our customers to build an environmentally-friendly, recycling-oriented society.
