(1) In the event a lot, parcel of real estate or building discharging sanitary sewage, industrial wastes, water or other liquids into the Town's sanitary sewerage system, either directly or indirectly, is not a user of water supplied by the water utility serving the Town, 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 Town, then the amount of water used shall be otherwise measured or determined by the Town. In order to ascertain the rate or charge provided in this division, 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 Town for the determination of sewage discharge.

(2) In the event a lot, parcel of real estate or building discharging sanitary sewage, industrial wastes, sewerage systems, either directly or indirectly, is a user of water supplied by the water utility serving the Town, and in addition, is a user of water from another source which is not measured by a water meter or is measured by a water meter not acceptable to the Town, then the amount of water used shall be otherwise measured or determined by the Town. 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 Town for the determination of sewage discharge.

(3) In the event two (2) or more residential lots, parcels of real estate or buildings discharging sanitary sewage, water or other liquids into the Town's sanitary system, either directly or indirectly, are users of water and the quantity of water is measured by a single water meter, then in each such case, for billing purposes, the quantity of water used shall be averaged for each user and the base charge and the flow rates and charges shall apply to each of the number of residential lots, parcels of real estate or buildings served through the single water meter.

(4) In the event two (2) or more dwelling units such as mobile homes, apartments, or housekeeping rooms discharging sanitary sewage, water or other liquids into the Town'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, billing shall be for a single service in the manner set out elsewhere herein, except that the minimum bill shall not be less than the number of such dwelling units times five dollars and fifty cents ($5.50) per month. In the case of mobile home courts, the number of dwelling units shall be computed and interpreted as the total number of mobile home spaces available for rent plus any other dwelling units served through the meter. A dwelling unit shall be interpreted as a room or rooms or any other space or spaces in which cooking facilities are provided.

(5) In the event two (2) or more business units or commercial units such as strip malls, business complexes, commercial centers or other multiple users discharging sanitary sewage, water or other liquids into the Town'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, billing shall be for a single service in the manner set out elsewhere herein, except that the minimum bill shall not be less than the number of such business units times the minimum base rate for the meter installed per month.

In the event the average water usage for the previous months is greater than the water usage for the summer months, then the billing for sewage services shall be computed on the actual water used in the month for which the sewage service bill is being rendered. Domestic and/or residential sewage service as applicable to the sprinkling rate shall apply to each lot, parcel of real estate or building which is occupied and used as a single-family residence. The sprinkling rate shall not apply to any premises which are partially or wholly used for commercial or industrial purposes. In the event a portion of such premises shall be used for commercial or industrial purposes, the owner shall have the privilege of separating the water service so that the residential portion of the premises is served through a separate meter and in such case the water usage as registered by the water meter serving such portion of the premises used for residential purposes would qualify under the sprinkling rate.
