B. 
"Shall" is mandatory; "may" is permissible.
A. 
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. 
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. 
Measurement of flow from high strength or toxic waste dischargers.
(1) 
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) 
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. 
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. 
Waste sampling.
(1) 
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) 
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. 
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. 
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. 
Billing period. Sewer service charge for all customers shall be billed on a monthly basis.
B. 
Payment. Sewer service charges shall be payable 20 days after the billing date to the City of Weyauwega.
C. 
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 1 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. 
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. 
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) 
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:

B. 
Variable charge (volume charge).
(1) 
Normal domestic wastewater volume charge (metered user): $2.94 per 1,000 gallons.
(2) 
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)]
Where:
C
=
Charge to sewer user for operation, maintenance and replacement cost for treatment works
F
=
Base monthly fixed charge
V
=
Wastewater volume in 1,000 gallons
B
=
Concentration of BOD5 from a user above the normal strength of 315 milligrams per liter
S
=
Concentration of suspended solids from a user above the normal strength of 235 milligrams per liter
P
=
Concentration of phosphorus from a user above the normal strength of 12 milligrams per liter
0.00834
=
Conversion factor (milligrams per liter to pounds)
C. 
Holding and septic tank discharges.
(1) 
Holding tank discharges. Charges to licensed dischargers of holding tank wastes shall be computed on the following basis:
(a) 
Assumed strength in milligrams per liter:

SS
1,300
P
25
(b) 
Volume charge: $8.56 per 1,000 gallons.
(2)

D. 
Tax incremental district charge.
[Added 1-23-2017 by Ord. No. 2017-2]
(1) 
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) 
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) 
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.
