This declaration brings the following advantages to the Manager:

2) On our Website, under the link: Your Water Bill>Your Current Bill the Manager can monitor and pay off electronically the Common Use Water Bill and also monitor the supply’s consumption history.

When can a consumer request for his bill to be reviewed by an EYDAP Committee and what documents are necessary?

  • a written application which is given by the local Commercial Services Division Office,
  • documents concerning the repair of leakage,
  • a copy of the official income statement and
  • special certificates in the case of disabled persons or people with special needs.

In the event one is sent an exorbitant bill, what can the water consumer do?

Exorbitant bills result when there are damages to the internal water network (leakage that is visible or not) or due to other reasons (water taps left open, water theft, etc). Exorbitant water consumption also results when a hydrometer malfunctions (EYDAP’s responsibility). The water consumers are normally informed by the meter-reader of unusually high water consumption or by the Regional Commercial Services Departments, which send the consumers a notification concerning the possible causes of the leakage.

What happens when the water consumption registered on the water bill is incorrect?

All bills that appear to be abnormally high are checked before their dispatch to water consumers, in order to verify that the correct meter reading was registered with the bill issue. If it is found that the initial water reading was inputted incorrectly, the bill (which has not yet been sent to water-consumer) is invalidated and a new bill is issued.

My water bill is overdue! Can I pay it off on the Web?

Yes, you can (with the exception of HSBC Bank)
