Company Profile

Based on proprietary technology
for the future of “Green” and “Water
Contribute to society
through the preservation of the global environment.

Our corporate philosophy states, "We will create a friendly future for people and the earth with our green and water technology”.
As these words and the name of our company, Green & Water, indicate, we have been contributing to society for 50 years since our establishment in 1970, based on two core businesses related to water and greenery: water treatment and landscape gardening.

In 2020, we became a member of HALVO Holdings and added a new axis, "Environmental Development Business”. In each of these businesses, our job is to propose "cleanliness" to the companies and facilities of our customers. We are committed to being a company that can contribute to society, keeping in mind that this work is also an important step toward the preservation of the global environment.
