It is important to store mineral water in homes, offices, schools and other facilities in preparation for a disaster.
Aqualine is committed to maintaining a quality of water that can help protect our lives in the event of an emergency. In addition to ensuring safety and security, we also provide Pure Natural Alkaline Storage Water that maintains its quality and fresh natural taste for 7 years.

Aqualine’s Pure Natural Alkaline Storage Water is produced from high-quality underground water that contains almost no impurities. The water wells up from 300 meters under the ground over the course of several hundreds to thousands of years.
Since the water is sterilized without being exposed to air before bottling, it maintains its quality and fresh taste and can be drunk safely even after 7 years. Official analysis confirmed that there was no breeding of bacteria.

Varied in geography and climate, Shimane Prefecture’s Kanagi-cho, where the water is sourced, has a rich natural environment. Official analysis confirmed that Aqualine’s Pure Natural Alkaline Storage Water, which is produced from Kanagi-cho’s rich natural environment, contains no radioactive iodine or cesium.
