FAQ（Water quality analysis／各種環境分析）

The tap water (including hot water) is subject to water quality standards set by the Water Works Law.
The tap water supplied from a water purification plant meets its standards, but the water quality may change during the process of being conveyed to the building or within the building’s facilities. For this purpose, the water collected from the faucet (the water we come in contact with) needs to be tested.
The water quality standards of the Act for Maintenance of Sanitation in Buildings are established by the standard values of the Water Works Law.
