[Amended 1-10-1995]
This article regulates the use of public drains
and the discharge of waters and wastes into the public sewerage systems
within the Village. It provides for the levying and collecting of
wastewater treatment service charges, sets uniform requirements for
discharges into the wastewater collection and treatment system and
is intended to enable the Madison Metropolitan Sewerage District to
comply with administrative provisions, water quality requirements,
toxic and pretreatment effluent standards and other discharge criteria
which are required or authorized by Wisconsin or federal law. Its
intent is to derive the maximum public benefit by regulating the characteristics
of wastewater discharged into the public sewerage system within the
Village.
Unless the context specifically indicates otherwise, the meaning of terms used in this article shall be as follows. The terms defined in Article II of the District's Sewer Use Ordinance shall have the same meanings when used in this article. The word "shall" is mandatory.

Definitions. The following terms shall have the following
meanings under this section:
All costs associated with repayment of debts incurred for
the construction and/or rehabilitation of a wastewater collection
system and treatment facility.
Wastewater with concentrations of CBOD, suspended solids,
total kjeldahl nitrogen and total phosphorus no greater than 200,
250, 40 and 10 milligrams per liter, respectively.
A user whose contributions to the sewerage system consist
only of normal domestic strength wastewater originating from a house,
apartment, flat, or other living quarters occupied by a person or
persons constituting a distinct household, business or commercial
enterprise.
All costs associated with the operation and maintenance of
the sewerage system.
All costs necessary to replace equipment as required to maintain
capacity and performance during the design life of the facility. A
separate, segregated, distinct replacement fund shall be established
and used for only replacement of equipment.
A service charge levied on users of the sewerage system for
payment of capital expenses as well as the operation and maintenance
costs, including replacement of said facilities.
B.
Policy. It shall be the policy of the Village of Maple
Bluff to obtain sufficient revenues to pay the costs of the operation
and maintenance of the sewerage system, including a replacement fund
(i.e., a cash account to be used for future expenditures for obtaining
or installing equipment, accessories or appurtenances which are necessary
to maintain the capacity and performance of the sewerage system during
the service life for which such facilities were designed and constructed),
through a system of sewer service charges as defined in this section.
The system shall assure that each user of the sewerage system pays
its proportionate share of the cost of such facilities.
C.
Basis for service charge. The semiannual service charge
shall be sufficient to pay the billing and customer-related administration
expense and the operation and maintenance expenses, including any
replacement of the sewerage system. The rates in this section shall
be reviewed not less than biennially. Rates shall be adjusted as required
to reflect actual number and size of users and actual costs. Users
will be notified annually of the portion of service charges attributable
to operation and maintenance.
D.
Sewer service charges. A sewer service charge is hereby
imposed upon each lot, parcel of land, building, or premises served
by the public sewer and wastewater facilities or otherwise discharging
sewage, including industrial wastes, into the public sewerage system.
Such sewer service charge shall be payable as hereinafter provided
and in amount determined as follows:
(1)
Category A service charges shall be imposed on users
whose water use is metered and whose sewer discharges are normal domestic
strength wastewater. The Category A sewer service charge is of the
following form:
|
Service Charge
|
=
|
Customer Charge + Volume Charge
| |
|
Customer Charge
|
=
|
A flat rate based on the size of the water meter
| |
|
Volume Charge
|
=
|
A volume of metered water in hundred cubic feet
multiplied by a volume rate
| |
|
Volume Rate
|
=
|
The volume unit price expressed in dollars per
100 cubic feet
|
(2)
Category B service charges shall be imposed on users
whose water use is not metered and whose sewage discharges normal
domestic strength wastewater. The Category B service charge shall
be of the form as follows: Service Charge = Equivalent Residential
Units multiplied by the Equivalent Residential Unit Rate. No user
shall be assigned less than one equivalent residential unit. The number
of residential unit equivalents for nonresidential users shall be
as determined by the Sanitary District Commissioners.
(3)
Category C service charges shall be imposed on users
whose sewage discharges are high-strength wastewater having concentrations
of carbonaceous biochemical oxygen demand (CBOD) greater than 200
milligrams per liter (mg/l) and/or suspended solids greater than 250
milligrams per liter (mg/l) and/or total kjeldahl nitrogen (TKN) greater
than 40 milligrams per liter (mg/l) and/or total phosphorus (TP) greater
than 10 milligrams per liter (mg/l). The minimum Category C service
charge shall be based on a concentration of 200 mg/l CBOD, 250 mg/l
suspended solids, 40 mg/l TKN, and 10 mg/l total phosphorus. The form
of the Category C service charge is as follows: Service Charge = Customer
Charge + Volume Charge + High Strength Surcharge. The customer charge
and the volume charge are similar to those components of the Category
A service charge.
(4)
The high-strength surcharge equals the excessive CBOD,
suspended solids, TKN, and total phosphorus multiplied by the respective
CBOD, suspended solids, TKN and total phosphorus rates. The excessive
CBOD, suspended solids, TKN and total phosphorus are the portions
of each of these constituents that are in excess of normal domestic
strength wastewater. The excessive amounts of CBOD, suspended solids,
TKN and total phosphorus are expressed in pounds and their respective
rates are expressed in dollars per pound.
E.
Reassignment of sewer users. The Village of Maple
Bluff will reassign sewer users into appropriate sewer service charge
categories if wastewater sampling programs and other related information
indicate a change of categories is necessary.
F.
The Village will maintain proportionate distribution
of operation, maintenance, and replacement costs.
G.
The user charge takes precedence over preexisting
agreements inconsistent with the regulations of this program.

of the sewerage system. Charges collected for replacement expenses
shall be credited to a segregated, nonlapsing replacement account.
These funds are to be used exclusively for replacement. When appropriated
by the Village of Maple Bluff, the credits to the sanitary sewerage
account shall be available for the payment of the requirements for
operation, maintenance, repairs, and depreciation of the sewerage
system consistent with 40 CFR 35.929. Any surplus outside the purview
of 40 CFR 35.929 in said account shall be available for the payment
of principal and interest of bonds issued and outstanding, or which
maybe issued, to provide funds for said sewerage system, or part thereof,
and all or a part of the expenses for additions and improvements and
other necessary disbursements or indebtedness, and the Village of
Maple Bluff may resolve to pledge each surplus or any part thereof
for any such purpose. All present outstanding sewer system general
obligation bonds, including the refunding bonds, shall be paid from
this fund as to both principal and interest.
Any person found in violation of the Sewer Use
Ordinance of the District or of any prohibition, limitation or requirement
contained therein shall be subject to the procedures and penalties
therein pertaining. Any such violation occurring within the Village
shall, in addition, be a violation of this article, subject to the
