[R.O. 1997 §710.140; CC 1989 §15-82; Ord. No. 1159 Art. V §7, 9-12-1994]
Where preliminary treatment or flow-equalizing facilities are provided for any waters or wastes, they shall be maintained continuously in satisfactory and effective operation by the owner at his/her expense.
[R.O. 1997 §710.150; CC 1989 §15-83; Ord. No. 1159 Art. V §8, 9-12-1994]
When required by the Director, the owner of any property serviced by a building sewer carrying industrial wastes shall install a suitable control manhole together with such meters and other appurtenances in the building sewer as are necessary to facilitate observation, sampling, and measurement of the wastes. Such manhole, when required, shall be accessibly and safely located and shall be constructed in accordance with plans approved by the Director. The manhole shall be installed by the owner at his/her expense and shall be maintained by him/her so as to be safe and accessible at all times.
[R.O. 1997 §710.160; CC 1989 §15-84; Ord. No. 1159 Art. V §9, 9-12-1994]
All measurements, tests, and analyses of the characteristics of water and waste to which reference is made in this Article shall be determined in accordance with the latest edition of "Standard Methods for the Examination of Water and Wastewater," published by the American Public Health Association, and shall be determined at the control manhole provided, or upon suitable samples taken at such control manhole. If no special manhole has been required, the control manhole shall be considered to be the nearest downstream manhole in the public sewer to the point at which the building sewer is connected. Sampling shall be carried out by customarily accepted methods to reflect the effect of constituents upon the sewage works and to determine the existence of hazards to life, limb, and property. (The particular analyses involved will determine whether a twenty-four-hour composite of all outfalls of a premises is appropriate or whether a grab sample or samples should be taken. Normally, but not always, BOD and suspended solids analyses are obtained from twenty-four-hour composite of all outfalls, whereas pHs are determined from periodic grab samples.)
[R.O. 1997 §710.170; CC 1989 §15-85; Ord. No. 1159 Art. V §10, 9-12-1994]
No statement contained in Sections 710.080 through 710.170 shall be construed as preventing any special agreement or arrangement between the City and any industrial concern whereby any industrial waste of unusual strength or character may be accepted by the City for treatment, subject to any payment therefor by the industrial concern.
[R.O. 1997 §710.180; CC 1989 §15-86; Ord. No. 1159 Art. VI §1, 9-12-1994]
No unauthorized person shall maliciously, willfully, or negligently break, damage, destroy, uncover, deface, or tamper with any structure, appurtenance, or equipment which is a part of the sewage works. Any person violating this provision shall be subject to immediate arrest under charge of disorderly conduct.

A. 
The Director and other duly authorized employees of the City bearing proper credentials and identification shall be permitted to enter all properties for the purposes of inspection, observation, measurement, sampling, and testing in accordance with the provisions of this Article.

B. 
While performing the necessary work on private properties referred to in Subsection (A), the Director or duly authorized employees of the City shall observe all safety rules applicable to the premises established by the company. The company shall be held harmless for injury or death to the City employees, and the City shall indemnify the company against loss or damage to its property by City employees and against liability claims and demands for personal injury or property damage asserted against the company and growing out of the gauging and sampling operation, except as such may be caused by negligence or failure of the company to maintain safe conditions as required in Section 710.160.
C. 
The Director and other duly authorized employees of the City bearing proper credentials and identification shall be permitted to enter all private properties through which the City holds a duly negotiated easement for the purposes of, but not limited to, inspection, observation, measurement, sampling, repair, and maintenance of any portion of the sewage works lying within such easement. All entry and subsequent work, if any, on such easement, shall be done in full accordance with the terms of the duly negotiated easement pertaining to the private property involved.

A. 
The user charge system shall generate adequate annual revenues to pay the costs of annual operation and maintenance, including replacement and cost associated with debt retirement of bonded capital associated with financing the treatment works, which the City may by ordinance designate to be paid by the user charge system. That portion of the total user charge which is designated for operation and maintenance, including replacement of the treatment works, shall be established by this Article.

B. 
For residential, industrial and commercial contributors, user charges shall be based on water used during the current month. If a commercial or industrial contributor has a consumptive use of water or in some other manner uses water which is not returned to the wastewater collection system, the user charge for that contributor may be based on wastewater meter(s) or separate water meter(s) installed and maintained at the contributor's expense and in a manner acceptable to the City.

$6.22 per pound phosphorous
F. 
Any user which discharges any toxic pollutants which cause an increase in the cost of managing the effluent or the sludge from the City's treatment works, or any user which discharges any substance which singly or by interaction with other substances causes identifiable increases in the cost of operation, maintenance or replacement of the treatment works, shall pay for such increased costs. The charge to each user shall be as determined by the responsible plant operating personnel and approved by the Board of Aldermen.

These residents for which the City is unable to provide sewerage service shall not be required to pay sewerage charges.
C. 
This exemption shall only apply to those residences inside the corporate limits of the City which have been determined by the Public Works Director as being either economically or technically unfeasible for sewerage service.
[Ord. No. 1804, 1-14-2019]
The requirements of the Code of Ordinances notwithstanding, the City may provide sanitary sewer service within the boundaries of a public water supply district when a formal agreement has been reached with said district to provide monthly domestic water consumption data to be used for sewer billing purposes. The agreement should include other such terms and conditions as the Board of Aldermen may deem necessary.
