Any customer may file for adjustment of premium rate charges with the Superintendent. The Superintendent may grant an adjustment of the premium rate charges in accordance with the following criteria:
1. The cause of the high consumption was mechanical in nature (such as broken or leaky pipes or fixtures) rather than human carelessness.
2. The customer shall furnish proof that the mechanical failure was repaired promptly. This should be in the form of a repair invoice or statement or a materials receipt.
3. The adjustment shall be granted only for the billing period prior to the correction of the failure.
4. For those accounts granted an adjustment of the premium rate, the charge will be $5.00 plus normal rate.
