Why is the smart water meter still posting a bill of arrears on the door?

The reasons for posting the arrears list are as follows:

1. Abnormal data: Although the smart water meter can remotely monitor and read data, there may still be abnormal situations such as inaccurate data and data loss. In this case, the water company may need to post a bill of arrears to remind users.

2. Meter reading cycle: Even if the smart water meter is used, the water supply company still needs to read the meter according to a certain cycle to ensure the accuracy and integrity of the data. If the user fails to pay the water fee in time during this period, the water company may post a bill of arrears.

3. Call for water fee: If the user is in arrears for a long time, the water company can call for water fee by posting a bill of arrears.

4. Publicity and promotion: In order to improve users' awareness of payment, the water company may publicize and promote by posting arrears forms to remind users to pay water fees in time.
