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.

of food and from the handling, storage, and sale of food products
and produce.
GROUND GARBAGE.
The residue from the preparation, cooking, and dispensing

freely in suspension under normal flow conditions in sewers.
INCOMPATIBLE POLLUTANTS OR WASTEWATER
Wastewater or septage with pollutants or of such a strength
that will adversely affect or disrupt the wastewater treatment processes
or effluent quality or sludge quality if discharged to the sewerage
system facility.

NATURAL OUTLET
Any outlet, including storm sewers and combined sewer overflows,
into a watercourse, pond, ditch, lake or other body of surface or

a hydrogen ion concentration of 10.
PUBLIC SEWER
Any sewer provided by or subject to the jurisdiction of the
Village of Maple Bluff.
SANITARY SEWAGE
A combination of liquid and water-carried wastes discharged
from toilets and/or sanitary plumbing facilities, together with such

or groups of structures may be included as part of a sewer system
when such units are cost effective and are owned and maintained by
the Village of Maple Bluff.
SLUG LOAD
Any substance released at a discharge rate and/or concentration
which causes interference to wastewater treatment processes or plugging
or surcharging of the sewer system.
STANDARD METHODS

are to be permanently installed, they shall be of a type acceptable
to the MMSD.
