ECONOMIC UNIT.
(1) Each dwelling unit*, business*, industry, mobile home* located on a mobile home lot* or other lot, recreational vehicle* located on a recreational vehicle lot* and any other entity receiving city water and/or sewer services (*see definition in Marseilles Zoning Ordinance) or where water and/or sewer services would reasonably be expected. A building, building complex, mobile home park, or recreational vehicle park with more than one economic unit shall be considered as have the number of economic units housed therein regardless of the number of water meters or sewer connections contained therein. For high volume users of water or sewer and entities with an uncertain number of economic units, the Commissioner of Public Property may determine the number of economic units ascribed to such user based on average water consumption by other economic units. Any decision of Commissioner of Public Property may be appealed to the City Council. The number of economic units attributed to a campground, or to an owners' association of any planned development or other form of subdivision designed not for single family homes but for recreational vehicles where each recreational vehicle that does not have a city approved water meter (hereinafter camping facility) shall be determined by the following formula:
(2) Formula.
(a) The total monthly metered water usage for the camping facility shall be divided by the average of all water usage in the applicable geographic area (North or the Illinois River or South of the Illinois River). Such average shall be determined by the total water usage in the geographic area (minus the water account of any camping facility) divided by the total number of water accounts in the geographic area (minus camping facility accounts).
(b) The number of economic units, rounded down to a whole number, shall be the number of economic units applied to the monthly bill. Such formula shall be calculated monthly and the calculation shall be included with the monthly billing. The following is an example of the calculation:
(3) Example of formula.
(a) If in the month of August a camping facility located North of the Illinois has a total metered water usage of 4,141 units (414,100 gallons) and the average water usage of all water users North of the Illinois (except for the camping facilities) was 51 units (5,100 gallons), the August billing calculation to determine the number of economic units (to be multiplied against basic charges) would be as follows:
1. Camping facility metered water use.
2. Average water use North of Illinois River. Metered usage divided by average units rounded down to whole number:
4,141 units (414,100 gallons)
51 units (5,100 gallons)
81.19 economic units 81 economic units
(b) Economic Units of 81 multiplied by basic charge of $25.50* = $2,065.50 basic charge to be added to water and sewer usage charges (*in this example,*$25.50 is combined basic charges for water and sewer North of the Illinois River).
