How to deal with the tap water pollution of residents when the property receives the appeal?

First, let's see if your tap water is a secondary water supply. If it is a secondary water supply, but it is really polluted, you should say that the water supply has stopped, and the pool is being cleaned, and then the water supply will be carried out after the water quality test is qualified. If this is the water supplied by the water department, you can say that you called the water department and the water department has accepted it. If it has not been reflected to the water department, call the water department in front of the residents and tell the water department that the residents' demands will be inspected by the water department.
