A. The service charge to be paid by all contributors of the El Dorado Municipal Wastewater Collection and Treatment System is established under separate ordinance.

B. 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 source other than from the city's municipal water system, then the sewer user charge will be estimated as directed in the sewer user charge ordinance, unless the owner of lot, parcel of land, premises or facility installs, and maintains at his or her own expense, a water meter approved by the city's utilities 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. Any water meter to be installed by anyone other than the public utility department shall be approved in advance in writing by the director of public utilities prior to installation.

C. Where more than one water meter is installed for service to one industry or commercial business located at a single site, 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 business located at a single site.

D. 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 city clerk.

E. If wastewater service is commenced or terminated during a period for which bills are rendered, billing shall be prorated on a daily basis based on a standard thirty-day month.

F. The city shall annually review user charges and revise them, if necessary, to reflect, as a minimum, the following conditions:

1. User charges shall maintain a proportional distribution of operation, maintenance and replacement (OM&R) cost among all users and/or user classes.

2. User charges shall generate adequate revenues to pay the costs of OM&R.

3. All accounting procedures will be in accordance with generally accepted accounting principles (GAAP), under the auspices of the Municipal Finance Officers Association and Kansas Statutes.

G. 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.

H. Whenever current standards or guidelines are altered by any governmental agency, the user charges, if any, must be adjusted to reflect the costs of expanding and/or upgrading the treatment works required by these revisions. (Prior code § 9-323)
