Answer the question about the water in the house.

First, when you are in the city, every house in the city will be equipped with a tap water system when it is newly built. This matter is supervised, and the personnel who install tap water are also professional; The water supply will be cut off, but it won't happen if it is not tap water.

Second, real estate developers, including related personnel, will not add a reclaimed water pipeline system when they are in Gai Lou, because that will increase their costs. Even if it is installed, who will use the reclaimed water? In addition, as you said, each family has only one water meter, so that the water comes directly from the local water tower, and the water in the water tower is extracted by the water company according to the tap water purification standard.

So, the conclusion is:

Congratulations, you use tap water, and there will be no reclaimed water in the future.
