Water Solution
Evolution of technology to enhance water security
Water is an indispensable source of life for all living things.
KITZ supports a stable supply of water and contributes to enrich people’s daily lives.

Evolution of Technologies to Enhance the Security of Water
KITZ Group’s history started with water. Over the years, we have provided products that play a role in “water supply and drainage,” which controls the flow of water.
Since then, we have steadily evolved our “water security” technology into “water purification” technology, which uses membranes to clean water, and “recycling” technology, which makes effective use of limited water resources.
The KITZ Group comprehensively utilizes these technologies and experience to propose solutions that are truly needed by our customers through our “KITZ water solution” activities.
Through the Kitz water solution, we will contribute to solving water-related problems around the world.
