”Tap water”
We are so happy that we are able to get water suitable for drinking whenever twisting the faucet.
Tap water must be tested the quality and meet the requirements by the standards by the Water Supply Act.
So we use the tap water in the food and drink without worrying.
Japan's tap water is soft water and is easy to drink though there is of uneven degree by region.
PH of tap water is about 7.5.
The water supply agency must secure the amount of supply water that is required, which is also one of the important measures in addition to water quality management.
If tap water was cut off, we have immediately a hard time.
In such a case, a water truck will be allocated.
