For the purpose of this chapter, the following definitions shall apply unless the context clearly indicates or requires a different meaning.
ADMINISTRATION COSTS. Include costs, all or in part, related to the cost of billing, collection, administration of accounts, insurance, outside services and administration of the Sewer Utility. The administrative charge will be based upon the water meter size serving the building.
(1) An ADMINISTRATIVE COST CHARGE FACTOR is assigned as follows:
Meter Size | Charge Factor |
Meter Size | Charge Factor |
5/8 - 3/4 in. | 1 |
1 in. | 2.5 |
1-1/4 in. | 2.5 |
1-1/2 in. | 4 |
2 in. | 6 |
3 in. | 9 |
4 in. | 16 |
6 in. | 18 |
(2) The ADMINISTRATIVE COST per meter size will be determined by multiplying the Charge Factor times the base charge:
Base charge = Total administrative cost X (% if applicable)
Total number of charge factors for the village
APPROVING AUTHORITY. The Village Board or its designated agent. APPROVING AUTHORITY and VILLAGE are used interchangeably.
BOD (BIOCHEMICAL OXYGEN DEMAND). The quantity of oxygen utilized in the biochemical oxidation of organic matter, under standard laboratory procedure, in five days at 20ºC and expressed in milligrams per liter.
COMBINED SEWER. A sewer intended to receive both wastewater and storm water or surface water.
COMMERCIAL USER. Those users of the publicly owned treatment works, which deal primarily in the transfer of goods or services.
COMPATIBLE POLLUTANTS. Those pollutants generally characterized as BOD, suspended solids, pH and fecal coliform, together with any additional pollutants defined in the village’s WPDES permit, unless the concentrations of any of these pollutants are such that they interfere with the operation of the treatment works or exceed the limits established under §§ 52.04 and 52.05.
DEBT SERVICE CHARGE. The charge to the users, which shall, in whole or in part, defray the costs of retiring the debts incurred in the construction or retrofitting of any wastewater facilities, components or appurtenances by the village. The DEBT SERVICE CHARGE will be based upon the water meter size serving the building. A DEBT SERVICE CHARGE factor is assigned as follows:
Meter Size | Charge Factor |
Meter Size | Charge Factor |
5/8 in. - 3/4 in. | 1 |
1 in. | 2.5 |
1-1/4 in. | 2.5 |
1-1/2 in. | 4 |
2 in. | 6 |
3 in. | 9 |
4 in. | 16 |
6 in. | 18 |
The debt payment per meter size will be determined by multiplying the Charge Factor times the base charge:
Base charge = Total debt payment X (% if applicable)
Total number of charge factors for the village
DOMESTIC WASTEWATER. Waterborne wastes normally being discharged from the sanitary conveniences of dwellings, apartment houses, hotels, office buildings, factories and institutions, free of industrial wastes, in which the average concentration of suspended solids is established at or below 250 mg/l and the BOD is established at or below 250/mg/l.
FLAT CHARGE. The charge made to unmetered users for use of the treatment works.
HOLDING TANK. A buried temporary storage reservoir, usually located adjacent to the structure it serves, which directly receives raw wastewater from a building’s internal waste plumbing collection system. The waste contents are periodically removed by a septic tank pumper and transported elsewhere for treatment.
INCOMPATIBLE POLLUTANTS. Specifically defined in § 52.05. Generally, INCOMPATIBLE POLLUTANTS shall mean wastewater or septage with pollutants that will adversely affect or disrupt the wastewater treatment processes or effluent quality if discharged to the wastewater treatment facility.
INDUSTRIAL COST RECOVERY. Recovery by the village from industrial users of a wastewater works of the grant amount allocable to the treatment of wastes from such users; pursuant to § 204(b) of the Federal Act, being 33 USC §§ 1284; if and when applicable.
INDUSTRIAL USER AS DEFINED FOR INDUSTRIAL COST RECOVERY.
(1) Any nongovernmental user of publicly owned treatment works which discharges more than 25,000 gallons per day of sanitary waste, or a volume of process waste, or combined process and sanitary waste, equivalent to 25,000 gallons per day of domestic strength sanitary waste. Sanitary wastes are the wastes discharged from the average residential user in the village’s service area. The strength of the average residential waste in the village’s service area shall be defined in terms of a concentration of 250 mg/l biochemical oxygen demand (BOD) and 250 mg/l suspended solids (SS). These concentrations will be applied in determining equivalent volumes of process waste or combined discharge of sanitary and process wastes.
(2) Any nongovernmental user of publicly owned treatment works which discharges wastewater to the treatment works which contains toxic pollutants or poisonous solids, liquids or gases in sufficient quantity, either singly or by interaction with other wastes, to injure or interfere with any sewage treatment process, constitute a hazard to humans or animals, create a public nuisance or create any hazard in or have any adverse effect on the waters receiving any discharge from the treatment works.
INDUSTRIAL USER AS DEFINED FOR INDUSTRIAL USER CLASS. Any user or publicly owned treatment process that engages in processing, blending, assembling or in some way transforming of materials or substances into new products. This type of user would normally occupy an establishment described as a plant, factory or a mill.
INDUSTRIAL WASTE. The wastewater from an industrial user as distinct from domestic wastewater.
INSTITUTIONAL USER. A user of the publicly owned treatment works that functions primarily as a social, charitable, religious, educational or of a hospice nature.
MAY. The action referred to is permissive.
MINIMUM CHARGE. The amount charged to each user regardless of volume of use. This charge provides the user a minimum of 2,000 gallons of use.
MONITORING STATION. A location where a method of monitoring wastewater can be performed for a specific customer before his, her or their wastewater is introduced into the village wastewater collection system.
OPERATION AND MAINTENANCE COSTS. All costs incurred in the operation and maintenance of the village’s wastewater collection system and wastewater treatment facility. This class of cost shall include but not be limited to labor, energy, chemicals and replacement costs, but excludes debt retirement.

REPLACEMENT COST. Expenditures for obtaining and installing equipment, accessories or appurtenances that are necessary to maintain the capacity and performances during the service life of the Wastewater Treatment Works for which such works were designed and constructed.
