General provisions are stated in Ch. NR 205, Wis. Adm. Code.
B.Â
"Shall" is mandatory; "may" is permissible.
A.Â
Sewer users served by City water meters. There is
hereby levied and assessed upon each lot, parcel of land, building
or premises having a connection with the wastewater system and being
served with water metered by the City of Weyauwega a user charge based,
in part, on the quantity of water used as measured by the City water
meter on the premises.
B.Â
Sewer users served by unmetered sources. Except as
provided below, no sewer user shall be served by unmetered sources
(private or public). All persons discharging wastewater into the public
sanitary sewer system shall be required to have water meters installed
for the purpose of determining the volume of water consumed. Where
wastewater meters are already installed, the water meters will not
be required. Water meters shall be furnished by the City and installed
under its supervision.
C.Â
Measurement of flow from high strength or toxic waste
dischargers.
(1)Â
The volume of flow used for computing the user charge shall be the metered water consumption of the user as shown in the records of meter readings maintained by the City, except as noted in Subsection D below.
(2)Â
Provisions for deductions: In the event that a sewer
user discharging industrial waste into the public sewers produces
evidence satisfactory to the approving authority that more than 20%
of the total annual volume of water used for all purposes does not
reach the public sewer, then the determination of the water consumption
to be used in computing the waste volume discharged into the public
sewer may be made a matter of agreement between the approving authority
and the user. Satisfactory evidence shall be evidence obtained by
approved metering.
D.Â
Metering of industrial waste. Devices for measuring
the volume of waste discharged may be required by the approving authority
if this volume cannot otherwise be determined from the metered water
consumption records. Metering devices for determining the volume of
waste shall be installed, owned, and maintained by the discharger.
A maintenance schedule must be accepted by the approving authority.
Following approval and installation, such meters may not be removed
without the consent of the approving authority.
E.Â
Waste sampling.
(1)Â
Industrial wastes discharged into the public sewers
shall be subject to periodic inspection and a determination of character
and concentration of said wastes. The sampling may be accomplished
either manually or by the use of mechanical equipment acceptable to
the approving authority. The use of flow proportional composite sampling
is preferred.
(2)Â
Installation, operation and maintenance of the sampling
facilities shall be the responsibility of the user discharging the
waste and shall be subject to the approval of the approving authority.
Access to sampling locations shall be granted to the approving authority
or its duly authorized representatives at all times. Every care shall
be exercised in the collection of samples to ensure their preservation
in a state comparable to that at the time the sample was taken.
F.Â
Free service. No user shall receive free service or
pay a sewer use charge less than the user's proportional share of
operation, maintenance and replacement costs.
G.Â
Outside service. All users within the sewer service
area of the City of Weyauwega shall be treated equally as to a sewer
use charges regardless of their location with respect to the City
boundaries.
A.Â
Billing period. Sewer service charge for all customers
shall be billed on a monthly basis.
B.Â
Payment. Sewer service charges shall be payable 20
days after the billing date to the City of Weyauwega.
C.Â
Penalties. Charges levied in accordance with this
article shall be a debt due to the City of Weyauwega. If the debt
is not paid within 20 days after it is due and payable, it shall be
deemed delinquent. There shall be an added penalty of 1Â 1/2%
of the amount of the monthly bill. Charges and penalties shall constitute
a lien upon the property serviced and be recorded on the tax roll
of the City of Weyauwega. Change of ownership or occupancy of premises
found delinquent shall not be cause for reducing or eliminating these
penalties.
D.Â
Notification. Each user shall be notified annually,
in conjunction with a regular bill, of the rate schedule attributable
to wastewater treatment services, including an explanation of the
charges.
[Amended 4-19-2011 by Ord. No. 2011-5]
A.Â
Fixed charge. The purpose of the fixed charge is to recover the debt
service charges incurred by the City in the construction of the wastewater
treatment plant modifications:
[Amended 10-15-2012 by Ord. No. 2012-2]
(1)Â
Nonallocated fixed charges. The base fixed charge for all nonallocated
users shall be based on the size of their water meter(s) in accordance
with the schedule below. Unmetered residential users shall be considered
to be equivalent to a five-eighths-inch meter. Other unmetered users
will be evaluated on a case-by-case basis by the approving authority:

Wastewater of greater than normal strength. Charges to users discharging
wastewater of greater than normal strength shall be computed in accordance
with the formula presented below:
C = F + 2.94 x V + 0.00834 x V x [($0.31 x B) = ($0.432 x S)
+ ($4.379 x P)]

Tax incremental district charge.
[Added 1-23-2017 by Ord.
No. 2017-2]
(1)Â
A tax incremental district (TID) charge is hereby imposed upon the City for costs of the wastewater treatment facility expansion (the project) which are allocable to improvements undertaken which benefit the City Tax Incremental District No. 6. The charge imposed upon the City and allocable to Tax Incremental District No. 6 for the project is up to 70% of the total principal and interest payments, plus the debt coverage requirements of the loan to construct the project. The estimated maximum annual charge for said project is expected to be $299,600. This utility charge may be modified by Subsection D(2) of this section.
(2)Â
Additional TID charge. An additional TID charge is hereby imposed
under the following conditions: If the life of the loan for a project
exceeds the legal life of the City TID No. 6, the City reserves the
right to charge said TID, during the life of the TID, for payments
which will become due and payable after the TID has expired, for principal
and interest payments allocable to the project.
(3)Â
Billing TID. The TID charge shall be billed to the City semiannually, approximately six weeks prior to the debt service date(s). The payment shall be made from the TID within 20 days of billing to the City of Weyauwega Sewer Utility. This obligation shall only apply to the debt costs incurred and due for the project. Upon final debt service payment by the sewer utility for the project, this § 460-43D shall be repealed.
The City of Weyauwega shall conduct an annual
audit, the purpose of which shall be to reestablish the equity and
adequacy of the user charges relative to changes in system operation
and maintenance costs.
