[Amended by Ord. No. A-528-89, 1989; at time of adoption of Code (see Ch. 1.01, Code Adoption)]
A. 
Sewer users served by Utility water meters. There is levied and assessed upon each lot, parcel of land, building or premises having a connection with the wastewater collection system and being served with water solely by the Water Utility, a sewer service charge based, in part, on the quantity of water used, as measured by the Water Utility water meter used upon the premises.
B. 
Sewer users served by private wells. If any person discharging wastewater into the sanitary sewers procures any part or all of his water from sources other than the Water Utility, all or part of which is discharged into the sanitary sewers, the person shall have water meters installed by the Water Utility at the person's expense for the purpose of determining the volume of water obtained from these sources. Where sewer meters are already installed, water meters will not be required. The water meters shall be furnished by the Water Utility and installed under its supervision, all costs being at the expense of the person requiring the meter. The Water Utility will charge for each meter a rental charge set by the Water Utility to compensate for the cost of furnishing and servicing the meter. The rental charge shall be billed at the time the sewer service charge is billed.
C. 
Deduct meters. If a person feels that a significant amount of metered water does not reach the sanitary sewer, he can at his own expense, with approval of the approving authority, install such additional meters or metered services as are necessary to calculate the volume of water not discharged to the sanitary sewer. Metered water not discharged to the sanitary sewers shall not be subject to sewer service charges. Requests to install additional meters must be made in writing to the approving authority.
Sewerage service rendered by the Water/Wastewater Utility shall be paid for at the current rates and charges in effect and as approved by the Village Board; description of various rate components is as follows:
A. 
General sewer service. Metered.
1. 
Quarterly service charge. This is a fixed quarterly charge that applies on a meter size basis to all metered customers discharging domestic strength sewage up to 200 mg/l per liter BOD, 250 mg/l per liter suspended solids, 6 mg/l per liter for phosphorus and 20 mg/l per liter for nitrogen.
2. 
Volume charge. A volume charge applies for each 1,000 gallons domestic strength sewage discharged to the sanitary sewer system.[1]
[1]
Editor's Note: Original § 12.08.090A.3, Sprinkling credit for residential customers, which immediately followed this subsection, was repealed 11-19-2012 by Ord. No. 0011-2012.
B. 
High strength sewer service, metered. Where the strength of any contributor exceeds the strength limitations of 200 milligrams per liter for BOD, 250 milligrams per liter for suspended solids, six milligrams per liter for phosphorus and 20 milligrams per liter for nitrogen, a periodic sampling shall be taken and wastewater analyzed to determine the strength of said waste which will be billed at the high strength rates currently in effect.
[Amended by Ord. No. 035 Series 2002; Ord. No. 008, Series 2003]
C. 
Reassignment of sewer users. The approving authority will reassign sewer users into appropriate sewer service charge categories if wastewater flow monitoring and sampling programs or other related information indicate a change of categories is necessary.
D. 
General sewer service unmetered. This rate shall be applied only to single-family residential and small commercial customers and approximates the cost for 18,000 gallons per quarter discharged to the sewer system. If it is determined by the Utility that the user discharges more than 18,000 gallons per quarter to the system, an additional charge of the effective rate per 1,000 gallons will be made for estimated additional usage.
[Amended by Ord. No. 035 Series 2002; Ord No. 008, Series 2003]
Note: Larger sewer customers not connected to the municipal sewer system will be required to rent a water meter from the Utility to measure the water used, and the regular sewer rates will be applied.
E. 
Disposal of septic tank and holding tank wastes.
1. 
No person in the business of gathering and disposing of septic tank sludge or holding tank sewage shall transfer such material into any disposal area or public sewer unless a permit for disposal has been first obtained from the approving authority. Written application for this permit shall be made to the approving authority and shall state the name and address of the applicant; the number of its disposal units; and the make, model and license number of each unit. Permits shall be nontransferable except in the case of replacement of the disposal unit for which a permit shall have been originally issued. The time and place of disposal will be designated by the approving authority. The approving authority may impose such conditions as it deems necessary on any permit granted.
2. 
Any person or party disposing of septic tank sludge or holding tank sewage agrees to carry public liability insurance in an amount not less than $100,000 to protect any and all persons or property from injury and/or damage caused in any way or manner by an act, or the failure to act, by any of the person's or party's employees. The person or party shall furnish a certificate certifying such insurance to be in full force and effect.
3. 
All materials disposed of into the treatment system shall be of domestic origin or compatible pollutants only, and the person(s) agrees that he will comply with the provisions of any and all applicable ordinances of the Village and shall not deposit or drain any gasoline, oil, acid, alkali, grease, rags, waste, volatile or inflammable liquids, or other deleterious substances into the public sewers, nor allow any earth, sand or other solid material to pass into any part of the wastewater collection and treatment facilities.
4. 
Persons with a permit for disposing of septic tank sludge and/or holding tank sewage into wastewater collection and treatment facilities shall be charged in accordance with current and effective septage rates approved by the Village Board.
[Amended by Ord. No. 035, Series 2002; Ord. No. 008, Series 2003]
5. 
The person(s) disposing waste agrees to indemnify and hold harmless the Village from any and all liability and claims for damages arising out of or resulting from work and labor performed.
F.

All revenues for the replacement fund and for operation and maintenance of the wastewater collection and treatment facilities must be used solely for the replacement fund and operation and maintenance of the wastewater collection and treatment facilities.
[Amended by Ord. No. 002, Series 1995]
[Amended by Ord. No. 035, Series 2002; Ord. No. 008, Series 2003]
Sewer service charges shall be computed by the Utility according to the current and effective rates. Bills for sewer service are rendered quarterly and become due and payable on the first of the month following the period for which service is rendered. A late payment charge of 3% but not less than $0.50 will be added to bills not paid within 20 days of issuance. This one-time three-percent late payment charge will be applied only to any unpaid balance for the current billing period's usage. This late payment charge is applicable to all customers. The Utility customer may be given a written notice that the bill is overdue no sooner than 20 days after the bill is issued and unless payment or satisfactory arrangement for payment is made within the next 10 days, service may be disconnected pursuant to Ch. PSC 185, Wis. Adm. Code. A delinquent bill may be placed on the year's tax roll and collected along with other taxes due on the property. Change in ownership or occupancy of premises found delinquent shall not be cause for reducing or eliminating any charges or penalties due.
