§ 4-4-2 BILLING PRACTICE.
   (A)   A charge for water and sewer will be issued for each billing period. The charge will normally be determined from the difference between two (2) consecutive meter readings. When, for any reason, a meter reading has not been obtained, the charge may be "estimated" from quantities of water used during previous periods. Improved accessible property shall be billed the monthly minimum for water and sewer service, whether or not the service is used and regardless of whether the meter has been turned off.
   (B)   The city shall endeavor to give proper notice of water and sewer service charges but by law cannot guarantee delivery of mail. Failure to receive notice by mail shall not excuse customers from prompt payment of charges. It shall be the established policy of the city to accept only total and complete payments for charges billed.
