§ 52.01 DEFINITIONS.
   For the purpose of this chapter, the following definitions shall apply unless the context clearly indicates or requires a different meaning.
   BASIC WATER USER CHARGE. The base amount billed each billing period to every economic unit which includes, without limitation, costs for radium removal and IEPA testing
   BOD (BIOCHEMICAL OXYGEN DEMAND). The quantity of oxygen used in the biochemical oxidation of organic matter in five days at 20°C, determined by standard laboratory test procedures and expressed in mg/l.
   ECONOMIC UNIT. 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 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 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:
      (1)   Formula. 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).
         (a)   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:
         (b)   Example of formula. 
         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:
            Camping Facility metered water use:   4,141 units (414,100 gallons)
            Average water use North of Illinois River:   51 units (5,100 gallons)
            Metered usage divided by average:   81.19 economic units
            Units rounded down to whole number:   81 economic units
         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).
