Drinking water
■Thing about water receiving tank
Facilities that install water receiving tanks (tank water) as drinking water, such as buildings and condominiums, and supply drinking water to users are required to undergo regular inspections and cleaning the water tank once a year. .
■About the use of well water
We recommend tap water for drinking water.
In the highly urbanized city, well water is no longer clean due to changes in the surrounding environment, and may be contaminated in some cases.
In order for well water to always meet tap water quality standards (51 items), chlorination, advanced water treatment, and maintenance for it are necessary to improve the water quality.
Therefore, it is recommended that well water be used for toilet flushing water and garden watering in the garden, and using tap water for drinking water.
In addition, please refer to the following about laying of water supply.
