(1) Water consumption records shall be analyzed not less than once each year (or period equaling 12 months), to determine the quantities of water used.

(3) Billing shall be on the basis of 200-gallon units, and averages resulting in fractions of 200 gallons shall be raised to the next whole number of 200 gallons.
(B) At the option of the city, sewage service bills may be based upon the actual water consumption of each user for each month, or upon the average monthly water consumption of each user during the previous period of six months.
