13.02.040  Rendering of utility billings.
   The city will render utility billings to its customers as follows:
   A.   Billing period. Bills for electric, water, and sewer services will be rendered monthly.
   B.   Metered service.  Bills for metered service will be based on meter registrations.
      1.   Meters will be read as required for the preparation of regular bills, opening bills, closing bills and other reasons deemed necessary by the city.
      2.   It may not be possible to always read meters on the same day of the month, and should a monthly billing period contain less than 27 days or more than 33 days, a pro rata computation in the bill will be made.
   C.   Pro rata computation.
      1.   Except as provided below, all bills for electric service rendered for periods of less than 27 days or more than 33 days on a monthly billing period, will be computed in accordance with the applicable schedule. The size of the energy blocks, and the amount of the customer charge, service charge, demand charge, or minimum charge, specified therein, will be prorated on the basis of the ratio of the number of days in the period to the number of days in an average bimonthly or monthly period, which, for this purpose, shall be taken as 30 days.
      2.   When the total period of service is less than 34 days, no proration will be made, and no bill for such a service period shall be less than the specified monthly customer charge, service charge, demand charge, or minimum charge, except, when temporary service is furnished and the customer has paid the estimated cost of installing and removing the service facilities, proration will be made.
