   (A)   Meters will be read and bills rendered monthly, but the city may vary dates or length of period covered, temporarily or permanently, if necessary or desirable.
   (B)   Bill for water service will be figured in accordance with the rate schedule then in effect and will be based on the amount consumed for the period covered by the meter readings, but the amount payable for each month’s service shall not be less than the minimum charge prescribed in the schedule of rates.
   (C)   Charges for service commence when the meter is installed and connection is made, whether used or not.
   (D)   Bills for water service are due when rendered and are delinquent after 15 days. In the event the bill for water service is not paid in 15 days after it was rendered, a penalty in an amount fixed by the City Council shall be added and shall be paid by the customer.
   (E)   Readings from different meters will not be combined for billing, irrespective of the fact that such meters may be for the same or different premises, or for the same or different customers, or for the same or different services.
   (F)   Delinquent notices will be mailed to the customer 20 days after the first billing, and if not paid within ten days after date of the second mailing, water service may be discontinued.
   (G)   Failure to receive bills mailed or notices shall not prevent the bills from becoming delinquent nor relieve the customer from payment.
