A.
Purpose. The purpose of this division is to establish
the basis for reasonable charges for the cost of collection, transportation
and treatment of wastewater.
B.
Classes of charges. Three classes of wastewater charges
shall be established as follows, and "wastewater" shall include wastewater
from residential, multifamily, commercial, governmental and industrial
classes:
C.
Effective total metered water consumption. The term
"effective total metered water consumption" shall mean:
1.
For quarters one, three and four (billed in April, October and January),
the treatment charge and transmission and maintenance charge shall
be based on metered water volume for the three-month period beginning
December 5 and ending March 5 of each year, which shall be reflected
in the April billing unless consumption in any given quarter is lower
than the metered water volume established on the April billing;
2.
For the second quarter (billed in July), the treatment charge and
transmission and maintenance charge shall be based on the actual metered
water volume for that quarter (March 5 to June 5). In the event that
December 5 or March 5 falls on a Saturday, Sunday or legal holiday,
the following or preceding business day shall be used in lieu of the
fifth. If consumption for quarters three or four is lower than the
established metered water volume for the December 5 through March
5 period, the metered water volume for that quarter will be used to
establish the treatment charge and transmission and maintenance charge
for that specific quarter.
|
Wastewater charges. For new residential and nonresidential class
customers in the City of Onalaska that do not have an established
sewer value or where the public water supply is not available, and
a private water supply is used or where metered records are not available,
water usage shall be calculated based on the average sewer value of
account classes within the City of Onalaska from the April billing.
New residential- or nonresidential-class customers who establish service
midquarter will be charged the City average for first quarter or actual
consumption, whichever is lower.
|
D.
Wastewater charges. The charges for wastewater shall
include a quarterly charge consisting of a treatment charge, transmission
and maintenance charge and a flat-rate charge. The treatment charge
and transmission and maintenance charge shall be based on the effective
total metered water consumption.
E.
Quarterly treatment rate charge.
1.
A quarterly treatment rate charge shall be assessed each residential-
and nonresidential-class customer. The quarterly treatment rate charge
is intended to generate sufficient revenues to pay the cost of wastewater
treatment by the City of La Crosse and to pay the amortization cost
of improvements to the La Crosse Interceptor Sewer System.
2.
The treatment rate shall be an amount established yearly by the Common
Council of the City of Onalaska based upon information provided by
the City of La Crosse, which shall be a sufficient amount to cover
the annual cost of wastewater treatment and the amortization cost
of improvements to the La Crosse Interceptor Sewer System.
F.
Quarterly transmission and maintenance charge and flat fee.
1.
The quarterly transmission and maintenance and flat-fee charge is
intended to generate sufficient revenues to pay for the cost of operation,
maintenance and depreciation of the Onalaska Sanitary Sewer Collection
System. The annual operating budget will be estimated prior to each
calendar year's operation.
2.
The transmission rate shall be an amount established yearly by the
Common Council of the City of Onalaska, based upon the annual operating
expense of Onalaska Sewer Utility.
3.
The quarterly transmission and maintenance charge shall be calculated
as follows:
a.
(Transmission rate ÷ 100 cubic feet) × effective
total metered water consumption.
4.
The quarterly sewer flat fee shall be determined as follows based
upon the size of the meter as established by the Common Council annually,
on file in the office of the City Engineer.
5.
The City shall reserve the right to require a meter for any user.
6.
Charges for a portion of a billing period shall be prorated by the
City.
G.
Payment of quarterly sewer charges; lien; penalty.
1.
Wastewater charges shall be payable upon receipt, subject to the
provisions of this section.
2.
Wastewater charges shall not be payable in installments.
3.
Charges remaining unpaid for a period of 20 days or more from the
date of the wastewater utility bill shall be assessed a late payment
penalty charge of 3% of the amount billed, in addition to all other
charges, penalties or interest, when the delinquent charge is extended
upon the tax roll.
4.
If a charge and/or late penalty remains unpaid for a period of 20
days after the date of the utility bill, such charge and penalty shall
become a lien upon the real property to which it applies, as provided
in § 66.0809, Wis. Stats., and other applicable provisions
of the Wisconsin Statutes, as from time to time amended or renumbered.
5.
Delinquent charges and penalties shall be automatically extended
upon the next available tax roll as a delinquent tax against the real
property, and all proceedings relating to the collection, return and
sale of property for delinquent real estate taxes shall apply to such
charges.
6.
The City reserves the right to disconnect services pursuant to Wisconsin
Administrative Code § PSC 185.37, Wis. Stats., as may be
amended.
H.
Billing schedule. Billing intervals shall be established
by the City. If it has been impossible to read the water meter and
as a result been overestimated, there shall be no rebate on the sewer
bill. No credits shall be given on such estimated bills unless proof
is submitted of correctable error and a solution is possible.
I.
Unknown water leaks. If a leak unknown to the user is
found in an appliance or the plumbing, the City use shall be adjusted
based on the City's current leak adjustment policy. No such adjustment
shall be made for sewer after the customer has been notified and has
had an opportunity to correct the condition.
J.
Special treatment charges. Each user which discharges
wastewater other than domestic or discharges toxic pollutants which
cause an increase in the cost of managing the collection or treatment
systems as determined by the City shall pay for such increased costs.
K.
Distribution of costs. The costs of operation and maintenance
of all flow not directly attributable to users, e.g., infiltration
and inflow, shall be distributed among all users on the basis of the
flow volume of users.
L.
Records. The City shall keep the records necessary to
comply with applicable state or federal requirements.
A.
Prohibited discharge. No person shall discharge or cause
to be discharged any stormwater, surface water, groundwater, roof
runoff, subsurface drainage, uncontaminated cooling water or any other
unaltered water to any sanitary sewer.
B.
Authority to restrict industrial wastewaters. The City
reserves the right to refuse or limit the amount or character of any
or all industrial wastewaters from an industry or combination of industries
as may be necessary to ensure adequate treatment and proper operation
of the public sewer collection system. All users must meet City of
La Crosse sewerage rules, regulations, and ordinances for discharge
to the La Crosse Wastewater Treatment Plant. The City of La Crosse
has the authority to sample discharged sewerage.
C.
Prohibited substances. No person shall discharge or
deposit or cause to allow to be discharged or deposited into the wastewater
collection system any wastewater or substances which contain the following:
1.
Liquids, solids or gases which, by reason of their nature or quantity,
may be sufficient, either alone or by interaction with other substances,
to cause fire or explosion or be injurious to the wastewater collection
system or personnel engaged in the operation, maintenance or repair
or monitoring of the same. At no time shall two successive readings
on the explosion meter, at the point of discharge into the wastewater
collection system, be more than 5% of the lower explosive limit (LEL)
of the meter, nor shall any single reading exceed 10% of the LEL.
2.
Solid or viscous wastes which will or may cause obstruction to the
flow in a sewer require excessive cleaning or maintenance or otherwise
interfere with the proper operation of the wastewater collection system.
3.
Garbage that has not been ground or comminuted to such a degree that
all particles will be carried freely in suspension under flow conditions
normally prevailing in the public sewers, with no particle greater
than 1/2 inch in any dimension.
4.
Noxious or malodorous solids, liquids or gases which, either singly
or by interaction with other wastes, are capable of creating a public
nuisance or hazard to life, or are or may be sufficient to prevent
entry into the wastewater collection system for the purpose of monitoring,
maintenance or repair.
5.
Any waste which will cause corrosion or deterioration of the collection
system. All wastes discharged into the wastewater collection system
must have a pH value in the range of six standard units to nine standard
units at the point of discharge into the wastewater collection system.
Prohibited materials include, but are not limited to, compounds and
substances which will react with water to form acidic or alkaline
products.
6.
