Bills for service shall be rendered periodically at intervals no less than monthly
and not greater than quarterly at the direction of the utilities director and shall
be due when rendered. A bill shall be deemed rendered when mailed by United States
mail, postage prepaid, or when delivered to the customer's address shown on the application
for service. No partial payment of any bill rendered will be accepted by the county
unless authorized by the utilities director or authorized representative, in writing,
indicating the reason therefor, such as a contested billing, consumption or hardship.
