(A) Rates and charges shall be collected for the use of and services rendered by the municipal sewage works from the owners of each lot, parcel of land, or building that is connected with and uses the works by or through any part of the sewerage system of the city, or otherwise discharges sanitary sewage, industrial waste, water, or other liquids, either directly or indirectly, into the sanitary sewerage system of the city. Rates and charges shall be in an amount determinable as follows.
(1) Sewage rates and charges shall be based on the quantity of water used on or in the property or premises as measured by the water meter there in use, except as otherwise provided in this chapter. Sewage service rates for all users within the city, out of the city but in the state, and out of the state shall be as follows:

However, the minimum charge for sewage treatment service for any user, whether a metered water consumer, a flat rate consumer, or not a water customer, shall be not less than $10.72 in 2019 and subject to increases in subsequent years as depicted in the chart above per month for all users within the city, not less than $16.10 in 2019 and subject to increases in subsequent years as depicted in the chart above for all users out of the city but in the state, and not less than $20.14 in 2019 and subject to increases in subsequent years as depicted in the chart above for all users out of the state.
(3) For those users whose wastewater has a greater strength of toxicity than normal domestic sewage, a surcharge in addition to the normal user charge, will be collected. Any wastewater that has a biochemical oxygen demand (hereinafter “B.O.D.”) or suspended solids (hereinafter “SS”) over 250 milligrams per liter (hereinafter “mg/l”) is considered excessive. Any wastewater with a pH below 5.5 standard units (hereinafter “SU”) and above 9.5 SU is considered toxic.
(a) 1. The following surcharge rates shall apply to each user inside the city that has received permission from the municipal sewage works to contribute excessive strength sewage:

2. The surcharge rates for all users out of the city but in the state that have received permission from the municipal sewage works to contribute excessive strength sewage shall be 150% of the above charges. The surcharge rate for all users out of the state that have received permission from the municipal sewage works to contribute excessive strength sewage shall be 125% of the surcharge rate for all users out of the city but in the state.
(b) 1. The excessive strength surcharge will be based on the following formula, with the total applied to the monthly bill of the affected user:
A(C-250) + B(D-250) x .00834 x E - Surcharge Payment ($/month)
2. Where formula components are as follows:
a. A = Surcharge rate for B.O.D., in $/pound;
b. B = Surcharge rate of SS, in $/pound;
c. C = User’s average B.O.D. concentration in mg/l;
d. D = User’s average SS concentration in mg/l; and
e. E = User’s monthly flow to sewage works per 1,000 gallons.
(c) No reduction in sewage service charges, fees, or taxes shall be permitted because of the fact that certain wastes discharged into the sewage works contain less than 250 mg/l of B.O.D. or less than 250 mg/l of SS.
(d)
A toxicity surcharge will based on excessive strength surcharges for each daily pH violation for all users within the city, 150% of the amount for all users out of the city but in the state, and 125% of the amount for all users out of the city but in the state for all users out of the state. Discharge flow with a pH below 5.5 SU and above 9.5 SU is considered a violation.
1. The toxicity surcharge shall be based on the following formula, with the total applied to the monthly bill of the affected user:
F x G - Surcharge Payment ($/month)
2. Where formula components are as follows:
a. F = Number of days of pH violation; and
b. G = Surcharge rate of pH violation.
(4) The municipal sewage works shall maintain financial records to accurately account for expenditures for operation and maintenance of the sewer system, including normal replacement costs. The municipal sewage works shall review not less than annually the sewage works, debt service obligations, and sewer service charges to accomplish the following:
(a) Generate sufficient revenues to offset costs associated with the proper operation and maintenance of the sewage system and to meet debt service requirements;
(b) Maintain an equitable distribution of operation and maintenance costs among users of the treatment system;
(c) Adjust billings to reflect charges such as, but not limited to, administrative costs of monitoring flow and laboratory cost for analysis; and
(d) Adjust billings to reflect costs of equipment or facilities required to correct ordinance violations. These costs may be billed to parties responsible for the violations in a lump sum or assessed as a monthly surcharge.
(B) The quantity of water obtained from sources other than the water utility serving the city and discharged into the public sanitary sewerage system may be determined by the city in the manner as the proper officers of the city shall elect, and the sewage services may be billed at the above rates. In the event a lot, parcel of land, or building discharging sanitary sewage, industrial waste, water, or other liquids either directly or indirectly into the city’s sanitary sewage system is a user of water supplied by the water utility serving the city, and in addition uses water obtained from another source, or is not a user of water supplied by the water utility serving the city, and the water used thereon or therein is not measured by a meter or is measured by a meter unacceptable to the city, then the amount of water used shall be otherwise measured or determined by the city in order to ascertain the rates of charge; or the owner or other interested party, at his or her expense, may install and maintain meters, weirs, volumetric measuring devices, or any adequate and approved method of measurement acceptable to the city for determination of the sewage discharge.
