The quantity of water discharged into the sanitary sewage system and obtained from sources other than the utility that serves the city shall be determined by the city in such manner as the city shall reasonably elect, and the sewage service shall be billed at the above appropriate rates. Further, as is hereinafter provided in this section, the city may make proper allowances in determining the sewage bill for quantities of water shown on the records to be consumed, but which are also shown to the satisfaction of the city that such quantities do not enter the sanitary sewage system

    A.    In the event a lot, parcel of real estate or building discharging sanitary sewage, industrial wastes, water or other liquids into the city sanitary sewage system, either directly or indirectly, 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 water meter, or is measured by a water meter not acceptable to the city, then the amount of water used shall be otherwise measured or determined by the city. In order to ascertain the rate or charge provided in this chapter, the owner or other interested party shall, at his expense, install and maintain meters, weirs, volumetric measuring devices or any adequate and approved method of measurement acceptable to the city for the determination of sewage discharge. If there is no meter or any adequate and approved method of measurement for residential lots or residential parcels of real estate, then the service charge for such sewage service shall be twelve dollars and seventy-five cents per month.

    B.    In the event a lot, parcel of real estate or building discharging sanitary sewage, industrial wastes, water or other liquids into the city's sanitary sewage system, either directly or indirectly, is a user of water supplied by the water utility serving the city and, in addition, is a user of water from another source which is not measured by a water meter or is measured by a meter not acceptable to the city, and then the amount of water used shall be otherwise measured or determined by the city. In order to ascertain the rates or charges, the owner or other interested parties, shall, at his expense, install and maintain meters, weirs, volumetric measuring devices or any adequate and approved method of measurement acceptable to the city for the determination of sewage discharge.

    C.    In the event two or more residential lots, parcels of real estate, buildings or dwellings discharging sanitary sewage, water or other liquids into the city's sanitary sewerage system, either directly or indirectly, are users of water and the quantity of water is measured by a single water meter, then, in such case, for billing purposes, the sewage rates and charges shall be based, either on the quantity of water used on the property or premises subject to such rates and charges, as the same is measured by said single water meter there in use and shown by consumption records of said water utility, or on the number of residential lots, parcels or real estate, buildings or dwelling units served through the single water meter times four dollars and fifteen cents, whichever is greater. In the case of trailer parks, the number of dwelling units shall be computed and interpreted as the total number of trailers located and installed in said park plus any other dwelling units served through the meter.

    D.    In order that the single-family domestic and residential users of sewage service shall not be penalized for sprinkling lawns during the months of June, July, August and September, the billing for sewage service for residences and/or domestic users for said months shall be the lower of:

    1.    The rate based on the quantity of water used during June, July, August and September; or

    2.    The mean average consumption of usage for the month of February, March and April.

    E.    In the event a lot, parcel or real estate or building discharges sanitary sewage, industrial waste, water or other liquids into the city's sanitary sewerage system, either directly or indirectly, and uses water in excess of twenty-five thousand gallons per month, and it can be shown to the satisfaction of the city that a portion of water as measured by the water meter or meters does not and cannot enter the sanitary sewage system, then the owner or other interested party shall install and maintain meters, weirs, volumetric measuring devices or any adequate and approved method of measurement acceptable to the city for the determination of sewage discharge.
