Business case description

The municipality starts the process by give a notice to the affected Subscriber of this process. Then, either the real estate owner or tenant, report the current value of the watermeter counter via the Smart Service Portal. The subscriber first enters:

  • the water meter number
  • location of the building (address)
  • if they are reporting as therole of an owner or of a tenant

As they confirm the named entries, they can report the current water meter readings into the system. After submitting, the system connects the account of the subscriber (who registered before) with the new values of the watermeter reading. Then the system checks the values for rules predefined by the municipality (e.g.deviation from the last year of +/- 10%). If the rules match, the values will be directed to the 3rd party software.

If there is a deviation, the municipality checks the entry an either start further clarification or submits the checked values to the 3rd party software where the values will be used for billing.
