As a water meter for a house connection, analog water meters are still the norm today. While in the case of an electricity connection, the data is now transmitted to the operator via a smart meter, water consumption must be read and announced annually by the homeowners. The annual reading of the water level is not yet a reasonable reason to record water consumption; rather, a record of water consumption provides a better overview on a day-to-day basis. As an example, an alarm could be triggered in the event of abnormal consumption, possibly allowing a quicker response. As possible triggers I can think of a defective toilet flush, a tap that has not been turned off or in the worst case a leaking pipe.
