Prepaid water means that the consumer purchases water credit in the form of a prepaid water token. When entered into the user interface unit (located in the consumer's home), the token instructs the water management device to allow a certain amount of water through the meter before closing.
Changing to a water meter may benefit you if you don't use much water. It may also be worth changing to a meter if your property has a high rateable value. This is because some water bills are based on the rateable value of the property.However, there are some disadvantages for prepaid water meters.
