[Code 1985 § 27-231; Code 2005 § 110-171]
A.
For the purpose of providing funds for the operation and maintenance of the sanitary sewerage system and for other purposes as allowed by applicable law, there is hereby fixed and established a system of user charges to be levied against each respective user thereof. Charges are based on the costs of operation and maintenance of the sanitary sewerage system including replacement as well as the volume, strength and delivery flow rate of the sewage. Costs of treating extraneous flows shall be included in the cost of operation and maintenance and, as such, shall be apportioned among the users on the same basis as the other operation and maintenance costs. The cost for treatment of toxic pollutants will be charged to the dischargers of these pollutants. The city shall review the user charges from time to time and no less often than annually and revise them as necessary to ensure that sufficient funds are available to pay the costs of sanitary sewerage administration, operation, maintenance and replacement and to ensure a proportionate distribution of the costs among the users. The base level charge is comprised of equal charges to each account to meet the debt requirements plus a volume related charge for normal strength sewage to pay the normal costs of administration, operation, maintenance and replacement, plus a surcharge for pollutants above normal strength to pay the costs of treating those pollutants. The city shall maintain such records as are necessary to document the adequacy and proportionality of the user charges. The records shall be maintained as long as required by all applicable rules and regulations. The users shall be notified, no less than annually, in conjunction with a regular bill, of the rates and the portion of the user charge attributable to wastewater treatment services.
B.
The monthly volume of sewage discharged by each user shall be assumed to be equal to the quantity of water metered to the user but, in the cases where the volume cannot be reasonably determined from the water so metered, the amount of sewage discharged into the city system shall be determined as provided in this section. On single-family dwellings, the charge per month shall be computed on the average monthly volume discharged during the months of December, January and February. The volume of wastewater discharged by new single-family customers shall be assumed to be equal to the average of all single-family customers until the start of the fiscal year following the next average monthly volume determination period.
C.
It shall be the duty of every owner and occupant of premises benefitted by such sanitary sewer facilities, when requested by a duly authorized agent of the city, to furnish such information as may be required by the city and necessary for a proper determination of the rate to be charged for such service. The owner, or occupant if other than owner, of such premises shall promptly advise the city clerk of any change in the character of the use of such premises or of additional facilities hereafter installed. Failure to so advise the city clerk will not relieve such owner or occupant of any additional charge arising out of the change of use of the premises or additional facilities, and the city clerk shall bill such owner and/or occupant accordingly for any such additional charge past due, nor will the city be obligated to credit such owner and/or occupant for any difference in charges arising out of any change in the use of the premises or reduction in facilities.
D.
A surcharge system meeting Environmental Protection Agency requirements will be developed if industries having above normal strength waste and/or wastes containing other pollutants that may increase the cost of operation and maintenance, desire to use the sewage facilities. There will be no above normal strength charge nor will there be any reduction in the base level charge when the total SS and/or BOD are equal to or less than 300 mg/l.
E.
The sewage shall be analyzed except the sewage from individual residences and establishments known to discharge only domestic wastewater which is assumed to be of normal strength will not ordinarily be analyzed. The analysis will be carried out in accordance with generally recognized methods.
F.
The individual monthly user charge shall be computed in accordance with the following formula:
Cu = Cb + (Ct/Vt)(Vu) |
Where: | ||
Cu | = | A user's monthly charge. |
Cp | = | A user's monthly share of the debt service. |
Ct | = | Total annual cost of administration, operation and maintenance and replacement. |
Vt | = | Total annual volume contribution from all users. |
Vu | = | The monthly quantity of wastewater discharged by the individual user (gal./mo.). |
Use of this formula will provide sufficient revenue to offset estimated costs.
When the BOD, suspended solids or other pollutant concentrations from a user exceed normal strength, a surcharge shall be added to the base charge. The surcharge shall be computed as follows:
Cp = | Pc(P)(Vu)(8.34) |
1,000,000 |
Where: | ||
Cp | = | Surcharge for an excessive strength pollutant ($/mo.). |
Pc | = | O&M cost for treatment of a pound of pollutant ($/lb.). |
P | = | Concentration of any pollutant from a user above a base level (mg/l). The base levels for BOD and SS are 300 mg/l each. |
Vu | = | (defined above). |
The summation of surcharges for each excessive strength pollutants produces the total user surcharge.
G.
Except as otherwise expressly provided in this article, each person from whose property or premises sewage is discharged into the sanitary sewage system of the city, but who is not a water customer of the city, is hereby required to meter, at its source, the quantity of water used with an appropriate meter to be approved by the city and to pay a monthly user charge upon the quantity of water thus metered and the strength of sewage discharged, to be computed in like manner as provided in this section.
H.
Each user of the sanitary sewerage system of the city who is a water customer of the city, but who also obtains, uses or consumes water from any source other than from the city, is hereby required to meter, at such source, the quantity used, with an appropriate meter to be approved by the city, and to pay a monthly user charge based upon the total quantity of water metered and the strength of sewage discharged, to be computed in like manner as provided in this section.
I.
No person shall use the sewer service of the city without paying for such sewer service.
