In the event a lot, parcel of land, premises or facility discharging wastewater, industrial process waste, water or other liquids, either directly or indirectly into the city's wastewater collection and treatment system or which eventually enters the system, is supplied with water from any other source other than from the city's municipal water system, then the sewer user charge will be estimated at the average monthly charge for all contributors, unless the owner of the lot, parcel of land, premise or facility installs, and maintains at his own expense, a water meter approved by the city's water department. This meter(s) shall serve as a control for the establishment of the sewer user charge and shall be accessible to the city's meter readers.
(Ord. 622 Art. 9 § 2, 1981)
Where more than one water meter is installed for service to one industry or commercial business located at a single site or adjoining sites, only one minimum monthly charge shall apply. The additional monthly charge shall apply to the total average winter water use from all meters which supply service to one industry or commercial businesses located at a single site or adjoining sites.
(Ord. 622 Art. 9 § 3, 1981)
Where it can be established that a contributor has had a water leak during the establishment of the contributor's average winter water use, the contributor's charge may be adjusted by the cashier of the utility office by using the previous year's average winter water use or portion thereof.
(Ord. 622 Art. 9 § 4, 1981)
The city shall annually review user charges and revise them, if necessary, to reflect, as a minimum, the following conditions:
A. 
User charges shall maintain a proportional distribution of operation, maintenance and replacement (OM&R) costs among all users and/or user classes;
B. 
User charges shall generate adequate revenues to pay the costs of OM&R;
C. 
All end of year balances collected through user charges to pay for OM&R must be carried over to the next year and user charges adjusted accordingly.
(Ord. 622 Art. 9 § 6, 1981)
Billings for wastewater service shall be rendered at the same time and on the same bills issued for water service, but shall be shown as a separate item from the charge for water.
(Ord. 622 Art. 9 § 7, 1981)
Whenever current standards or guidelines are altered by any governmental agency in such a manner as to cause expansion and/or upgrading of the treatment works, user charges and ICR rates, if any, must be adjusted in accordance with the current guidelines to reflect the costs of expanding and/or upgrading the treatment works.
(Ord. 622 Art. 9 § 8, 1981)
