Water utility fees

Your water bill is calculated based on the amount of water you use. Every two months, someone will come to read your water meter. If your household is connected to the public sewage system, you will also be billed for the use of sewage services, which should be paid together with your water utility fees.

New water bill calculation system

Water utility fees are determined based on the following two criteria:

  1. Amount of water used
  2. Diameter of water meter (see the photo on the right)

Content of your water bill
