of the sewer is not a factor.
NATURAL OUTLET
Any outlet, including storm sewers and combined sewer overflows,
into a watercourse, pond, ditch, lake, or other body of surface water
or groundwater.
NORMAL DOMESTIC SEWAGE
Sanitary sewage resulting from the range of normal domestic
activities, in which BOD5 and SS concentrations
do not exceed normal concentrations of:
(1)
A five-day, 20° C,, BOD of not more than
225 milligrams per liter.
(2)
A suspended solids content of not more than
225 milligrams per liter.
PERSON
Any and all persons, including any individual, firm, company,
municipal or private corporation, association, society, institution,
enterprise, governmental agency or other entity.
pH

The concentration is the weight of hydrogen ions in grams per liter
of solution. Neutral water, for example, has a pH value of seven and
a hydrogen ion concentration of 10-7.
PRETREATMENT
An arrangement of devices and structures for the preliminary
treatment or processing of wastewater required to render such wastes
acceptable for admission to the public sewers.
PRIVATE SEWER
Any sewer located outside of a public right-of-way or public
easement. Except as provided in this article, a private sewer shall
not be subject to the jurisdiction of the City of Weyauwega and the
