(A) In the event any meter fails to operate properly or to correctly register the water used, the charge for the period during which the meter fails to operate properly or fails to register water, shall be based upon the average daily consumption for the same period of the prior year by the same user. If such a reading is not available, the city shall estimate the amount of such consumption from all information available and the consumer shall be charged on the basis of such estimate for water consumed.
(`67 Code, § 4-6-13)
(B) When any water consumer makes a complaint that the bill for any particular period is excessive, the Public Works Department will, upon request, have such meter re-read and the service inspected for leaks. Should such consumer then desire that the meter be tested, he will be required to make a deposit of $10 to cover the cost of making such test. The meter will then be changed or tested. Should the meter be found to register over 3% more water than actually passes through it, another meter will be substituted therefor, and the fee of $10 shall be refunded to the person making the request. If the meter is found to register not over 3% the $10 deposit shall be forfeited to the city and the water bill paid as rendered.
