Does the property have the right to increase water charges?

After the property is authorized by the tap water company, it can charge the owner the tap water fee, and it is not allowed to charge the owner any additional fees such as handling fees.

Legal basis:

"Property Management Regulations" Article 44 In the property management area, water supply, power supply, gas supply, heating, communication, cable television and other units shall charge relevant fees to the end users. The realty service enterprise shall not charge additional fees such as handling fees to the owners if it accepts the entrusted collection of money.
