Section 1220-04-03-.18 - ADJUSTMENT OF BILLS(1) Bills which are incorrect due to meter or billing errors are to be adjusted as follows: (a) Whenever a meter in set service is tested and found to have overregistered more than two percent (2%), the utility shall adjust the customer's bill for the excess amount paid. If the time at which the error first developed or occurred can be definitely determined, the estimated amount of over-charge is to be based thereon.(b) Whenever a meter in service is found not to register, the utility may render an estimated bill. The utility shall estimate the charge for the water used by averaging the amount registered over a similar period preceding or subsequent to the period of non-registration or for the corresponding period in previous years, adjusting for any changes in the customer's usage. When it is found that the error in a meter is due to some cause, the date of which can be fixed the over-charge or the under-charge shall be computed back to but not beyond such date.(c) When a customer has been over-charged as a result of incorrect reading of the meter, incorrect application of the rate schedule, incorrect connection of the meter, or other similar reasons, the amount of the over-charge shall be adjusted, refunded, or credited to the customer.(d) When a customer has been under-charged as a result of incorrect reading of the meter, incorrect application of the rate schedule, incorrect connection of the meter, or other similar reasons, the amount of the under-charge may be billed to the customer.Tenn.
