The Village Board, pursuant to the provisions of § 66.0621(1)(b),
Wis. Stats., does hereby declare that the sewerage system of the Village,
consisting of the collection system (as hereinafter defined), waste
collection and disposal operations, sewerage system and all other
appurtenances, and equipment used for such purposes, or wastewater
treatment plant (as hereinafter defined), shall be designated the
"Village of Slinger Sewer Utility" or the "Sewer Utility." This public
utility is not a public service subject to regulation by the Wisconsin
Public Service Commission.
This chapter regulates the use of public and private sewers
and drains, discharge of septage into the public sewerage system,
and the discharge of waters and wastes into the public sewerage systems
within the Village of Slinger. It provides for and explains the method
used for imposing and collecting sewerage service charges, sets uniform
requirements for discharges into the wastewater collection and treatment
systems and the issuing of permits to certain users, and enables the
Village to comply with administrative provisions and other discharge
criteria which are required or authorized by the State of Wisconsin
or Federal law. Its intent is to derive the maximum public benefit
by regulating the characteristics of wastewater discharged into the
Village of Slinger sewerage system. This chapter shall supersede any
previous ordinance, rules or regulations, and shall repeal all parts
thereof that may be inconsistent with this chapter. If there is any
conflict between this chapter and any applicable statute, the state
statute shall be controlling.
The operation, management and control of the Sewer Utility is
vested in the Village Board. All records of the Sewer Utility shall
be kept by the Village Clerk in the Village Hall or other officially
designated place.
A. The Village Board or designated official shall have the power to
construct sewer lines for public use and shall have the power to lay
sewer pipes in and through alleys, streets, and public grounds of
the Village; and generally, to do all such work as may be found necessary
or convenient in the management of the sewer system. The Village Board
shall have power by itself, its officers, agents and servants, to
enter upon any land for the purpose of making an examination or to
supervise in the performance of its duties under this chapter, without
liability therefor; and the Village Board or designated official shall
have the power to purchase property which may be necessary for construction
of the sewer system or for any repair, remodeling or additions thereto.
B. The rules, regulations and rates hereinafter set forth shall be considered
part of the regulations applicable to every individual or entity connected
to the sewerage system and all persons discharging wastes to the sewerage
system. Such rules, regulations and rates may be changed from time
to time as determined by the Village Board and the right is reserved
to make special rates and contracts in all proper cases.
C. The Village Board shall cause an annual audit of the books of the
Sewer Utility to be made and shall make the books and records relating
to the Sewer Utility available for inspection during regular business
hours.
D. A proportionate distribution of operation, maintenance and replacement
costs shall be maintained among user classes. Users shall be notified
annually of the sewer service charges associated with the sewerage
system.
E. The Sewer Utility shall be able to utilize the full authority provided
in § 66.0821, Wis. Stats., with respect to financing methods,
sewerage service charges, and other matters therein dealt with, and
shall have all legal authority permitted for municipal utilities to
charge reasonable rates for services.
The application of this chapter, its rules, regulations and
rates shall apply to all individuals, firms, corporations and institutions
residing within the corporate limit of the Village and any person,
firm or corporation, by attachment to the sewerage system or otherwise
by contract or agreement coming within the Village sewer service area
subsequent to the effective date hereof and all entities hauling wastes
or trucking wastes and discharging to the sewerage system.
