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.
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. Charge for toxic pollutants. Any person discharging toxic pollutants
which cause an increase in the cost of managing the effluent or sludge
from the municipality's wastewater treatment facility shall pay for
such increased costs as may be determined by the Village Board.
G. Operation, maintenance and replacement fund accounts. All sewer service charge revenues collected for replacement costs shall be deposited in a separate and distinct fund to be used solely for replacement costs, as defined under §
12.08.010. All sewer service charge revenues collected for other operation and maintenance expenses shall also be deposited in a separate and distinct fund. 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.
