The city’s water company bills small and large consumers. Small consumers, including single-family homes and small housing companies, are billed four times a year or every three months. The water bill is always based on an estimate unless the water meter reading is reported before the invoice is generated. Water meters are not remotely readable.

Large consumers, including apartment buildings, large terraced houses and some businesses, are billed monthly. As of 2018, large consumers have switched to the self-reading of water meters as is the case for small consumers. If the customer wants to continue using the remote reading service, a fee is charged in accordance with the service price list.
