[1-5-1999; 2016 Code]
The sewerage system of the city shall be divided into two classes
of sewers, namely:
(A) Sanitary sewers. Sanitary sewers are those sewers which are designed
and used for the disposal of all waste products discharged from plumbing
fixtures located in buildings and structures along the line of such
sewer; the term "plumbing fixtures," shall not include downspouts
or any other fixture discharging rain water or refrigerating plant
cooling water. All of the territory comprised within the corporate
limits of the city shall be held to constitute one sanitary sewerage
district to be known as sanitary district number one. The system of
sanitary sewers shall, for the purposes of this chapter be considered
as consisting of the following separate parts:
(1)
Sewer main. A sewer main being the principal artery extending
along the public street, alley or other public way or city held easement
into which the laterals may feed.
(2)
Sewer service laterals. A sewer service lateral being that part
of the sewer lying between the street or curb line and the sewer main.
(3)
House sewer (or drain). A house sewer (or drain) being that
part of the sewer laid from the property to be served to the sewer
service lateral.
(B) Storm sewers. Storm sewers, drains, or ditches are those sewers designed
and used for the disposal and conveying of rain water, ground water,
subsurface water or unpolluted water from any source. Combined sanitary
and storm sewers are prohibited.
[10-16-1990; 1-5-1999; 2016 Code]
Regulations governing plans, specifications, construction and
costs regarding sanitary sewers, and provisions relating to special
assessments for the same shall be as set forth in the Wisconsin statutes,
and said rules and regulations are incorporated herein by reference.
[10-16-1990; 1-5-1999; 2016 Code]
The city clerk or director of public works shall keep a complete
record of the installation of all sewers, whether the same be sanitary
sewers or storm sewers and also of all connections between sewer mains
and service laterals and all provisions made for such connections
and generally of all materials pertaining to the sewerage system of
the city.
[10-16-1990; 4-15-1997; 1-5-1999; 2016 Code]
(A) Construction. All sanitary sewers and house laterals shall be constructed
under the latest edition of "standard specifications for sewer and
water construction in Wisconsin," and any other specifications adopted
by the approving authority, or as may be required by any other local,
state or federal agencies.
(B) Cost of connection. No person or any agent or employee thereof shall
connect or cause to be connected any building or buildings with any
sanitary sewer within the city without first securing a permit from
the board of public works. The fee for such permit shall be set by
resolution of the council. No fee shall be charged for issuance of
a permit where the property connected to said sewer has been assessed
for the cost of said sewer. No plumbing contractor shall cause such
connection to be made until such permit is issued.
(C) Laterals. The laying of all sewer service laterals from the sewer
main to the property line shall only be performed by a licensed plumber
or by the city. The entire expense thereof and any future expenses
incurred to maintain or repair a sewer service lateral shall be paid
for by the owner of the lot or parcel benefited thereby. No house
sewer shall be laid or sewer main tapped unless an application therefor
has been made to the city and filed with and approved by the plumbing
inspector. Such applications must in all cases be accompanied by a
fee set by resolution of the council, which shall be paid into the
city treasurer.
(D) Connections with main sewer. All connections with a sewer main shall
be made at a "Y" or "T" joint when possible. In the event no "Y" or
"T" joint can be located, connection to the sewer main shall be made
in such manner as is satisfactory to the plumbing inspector. No connection
to the sewer shall be approved by the plumbing inspector where any
part of the lateral shall extend into the sewer main.
(E) Laying of laterals. At the time of the laying of sewer mains, sewer
service laterals shall be constructed and laid from the sewer main
to the curb line of all adjoining parcels and lots abutting on that
part of the street wherein said sewer main is laid and the cost of
the construction of said sewer service lateral shall be charged to
the owners of the abutting parcels and lots. Provided, that if the
street in which said sewer main is placed is not to be permanently
improved, then such laterals shall be constructed to those parcels
and lots abutting on said sewer which are improved. All sanitary sewer
laterals shall have G-425 rubber gasket joints, except where deviation
is permitted by written authorization of the director of public works.
(F) Buildings to have individual connections. Unless by prior approval
of the city, every building shall have its separate connection with
the sewer main and no two or more buildings shall be connected with
the sewer main through one pipe.
(G) Work authorized. No person shall uncover, make any connections with
or openings into, use, alter, or disturb the public sewers or appurtenances
thereof without first obtaining a written permit from the approving
authority.
(H) Cost of sewer connection. All costs and expenses incident to the
installation and connection of the building sewer shall be borne by
the person making the connection.
(I) Use of old building sewers. Old building sewers may be used with
new buildings only when they are found on examination and test by
the approving authority, to meet all requirements for this chapter.
(J) Materials and methods of construction. The size, slope, alignment,
materials of construction of a building sewer, and the methods to
be used in excavating, placing of the pipe, jointing, testing, and
backfilling the trench shall conform to the requirements of the city's
building and plumbing codes or other applicable rules and regulations
of the city. In the absence of code provisions or in amplification
thereof, the materials and procedures set forth in appropriate specifications
of the ASTM and WEF manual of practice no. 9 shall apply.
(K) Building and sewer grade. Whenever possible, the building sewer shall
be brought to the building at an elevation below the basement floor.
In all buildings in which any building drain is too low to permit
gravity flow to the public sewer, sanitary sewage carried by such
building drain shall be lifted by an approved means and discharged
to the building sewer.
(L) Storm and ground water drains. No persons shall make connection of
roof downspouts, exterior foundation drains, areaway drains, or other
sources of surface runoff or ground water to a building sewer or building
drain which is connected directly or indirectly to a sanitary sewer.
All downspouts or ground water drains, etc., connected directly or
indirectly to a sanitary sewer must be disconnected within 30 days
of the date of an official written notice from the approving authority.
(M) Conformance to plumbing codes. The connection of the building sewer
into the sanitary sewer shall conform to the requirements of the building
and plumbing codes, or other applicable rules and regulations of the
city or the procedures set forth in appropriate specifications of
the American society of testing materials and water pollution control
federal manual of practice no. 9. All such connections shall be made
gastight and watertight. Any deviation from the prescribed procedures
and materials must be approved by the approving authority before installation.
(N) Inspection of connection. The person making a connection to a public
sewer shall notify the approving authority when the building sewer
is ready for inspection and connection to the public sewer. The connection
shall be inspected and approved by the approving authority.
(O) Barricades; restoration. All excavations for the building sewer installation
shall be adequately guarded with barricades and lights so as to protect
the public from hazard. Streets, sidewalks, parkways, and other public
property disturbed in the course of the work shall be restored in
a manner satisfactory to the approving authority.
(P) Outside connections restricted. No property shall be served by the
public sewer unless such property is located within the corporate
boundaries of the city, or a contract for service is approved by the
council and executed with the city.
[10-16-1990; 12-17-1991; 1-5-1999; 2016 Code]
(A) Sanitary sewers. No person shall discharge or cause to be discharged
any unpolluted waters such as storm water, ground water, roof runoff,
subsurface drainage, or noncontact cooling water to any sanitary sewer.
(B) Storm sewers. Storm water and all other unpolluted water shall be
discharged to such sewers as are specifically designated as storm
sewers, or to a natural outlet approved by the approving authority
and other regulatory agencies. Unpolluted industrial cooling water
or process waters may be discharged, on approval of the approving
authority or other regulatory agencies, to a storm sewer, or natural
outlet.
(C) Prohibitions and limitations. Except as provided in this chapter,
no person shall discharge or cause to be discharged any of the following
described waters or wastes to any public sewer:
(1)
Any gasoline, benzene, naphtha, fuel oil, or other flammable
or explosive liquid, solid, or gas.
(2)
Any waters or wastes containing toxic or poisonous solids, liquids,
or gases in sufficient quantity, either singly or by interaction with

by garbage grinders.
(5)
The following described substances, materials, waters, or waste
shall be limited in discharges to sanitary sewer systems to concentrations
or quantities which will not harm either the sanitary sewers, wastewater
treatment process, or equipment; will not have an adverse effect on
the receiving stream, or will not otherwise endanger lives, limbs,
public property, or constitute a nuisance. The approving authority
may set limitations more stringent than those established in this
chapter as such more stringent limitations are necessary to meet the
objectives of this chapter. The approving authority will consider
the quantity of subject waste in relation to flows and velocities
in the sewers, materials of construction of the sanitary sewers, the
wastewater treatment facility and other pertinent factors. No person
shall discharge any of the following waste materials into any city
sewer:
A)
Any liquid or vapor having a temperature higher than 140 degrees
Fahrenheit or 60 degrees Celsius.
B)
Any wastewater containing more than 25 mg/l of petroleum oil,
nonbiodegradable cutting oils, or products of mineral origin; wastewater

content shall be as stated in the current edition of standard methods.
C)
Any unground garbage. Garbage grinders may be connected to sanitary
sewers from homes, hotels, institutions, restaurants, hospitals, catering
establishments, or similar places where garbage originates from the
preparation of food in kitchens for consumption on the premises or
when served by caterers.
D)
Any waters or wastes containing the toxic and nonconventional
pollutants specified in the United States environmental protection
agency's list of priority pollutants to such degree that the

to treatment by the wastewater treatment processes employed, or are
amenable to treatment only to such degree that the wastewater treatment
facility effluent cannot meet the requirements of other agencies having
jurisdiction over discharge to the receiving waters.
H)
Any water or wastes which, by interaction with other water or
wastes in the sanitary sewer system, release objectionable gases,
form suspended solids which interfere with the collection system,
or create a condition deleterious to structures and treatment processes.
I)
Materials which exert or cause:
1)
Unusual BOD, chemical oxygen demand, or chlorine requirements
in such quantities as to constitute a significant load on the wastewater
treatment facility.
2)
Unusual volume of flow or concentration of wastes constituting
"slugs."
3)
Unusual concentrations of inert suspended solids (such as, but
not limited to, fuller's earth, lime slurries, and lime residues)

of septage into any public sewer or at the wastewater treatment plant
without written authorization of the approving authority.
[1-5-1999; 2016 Code]
No person shall cause or permit a discharge into the public
sanitary sewers that would cause a violation of the city's WPDES
permit and any modifications thereof.
[1-5-1999; 2016 Code]
No statement contained in this chapter shall be construed as
prohibiting any special arrangement between the approving authority,
with the concurrence of the council, and any person whereby a waste
of unusual strength or character may be admitted to the wastewater
collection and treatment facilities, either before or after pretreatment,
if there is no impairment of the functioning of the wastewater collection
and treatment facilities by reason of the admission of such wastes,
and no extra costs are incurred by the city without recompense by
the person; and, further provided, that all rates and provisions set
forth in this chapter are recognized and adhered to.
[1-5-1999; 2016 Code]
New connections to the city's sanitary sewer system will
be allowed only if there is available capacity in all of the downstream
wastewater collection and treatment facilities.
[10-16-1990; 1-5-1999; 7-6-2004; 6-17-2008; 2016 Code]
(A) Sewer users served by water utility water meters. There is hereby
levied and assessed upon each lot, parcel of land, building, or premises
having a connection with the wastewater collection system and being
served with water solely by the water utility, a sewer service charge
based, in part, on the quantity of water used, as measured by the
water utility water meter used upon the premises.
(B) Sewer users served by private wells. If any person discharging wastewater
into the sanitary sewers procures any part or all of his or her water
from sources other than the water utility, all or part of which is
discharged into the sanitary sewers, the person shall have a deduct
meter installed by the water utility at the person's expense
for measuring the volume of water obtained from these sources. Where
sewer meters are already installed, deduct meters may not be required.
The deduct meters shall be furnished by the water utility and installed
under its supervision, all costs being at the expense of the person
requiring the deduct meter. The water utility will charge for each
deduct meter a rental charge set by the water utility to compensate
for the cost of furnishing and serving the deduct meter. The rental
charge shall be billed when the sewer service charge is billed.
(C) Premises not connected to water system or metered rates. If a lot,
parcel of land, building or premises, being connected onto the municipal
sewerage system and discharging sewage, wastewater or other liquids
into the sanitary sewer or into the industrial sewer directly or indirectly,
which is not a user of the city water supplied by the city water utility,
and the water used is not measured by a water meter or is measured
by a water meter not approved by the city water utility, then the
amount of water used shall be otherwise measured or determined by
the approving authority to determine the sewer service charge or rental
provided in this chapter, or the owner or interested parties, at their
own expense, may install and maintain a meter acceptable to the approving
authority for such purpose in which case the foregoing rates shall
apply. In the case of a lot, parcel of land, building or premises
discharging sewage or industrial waste into a sanitary or industrial
sewer, either directly or indirectly when the water is not metered,
and the approving authority finds that it is not practical to attempt
to measure such by meter, the board of public works shall measure
such waste in such manner and by such methods as they find it practical
in light of the conditions and attendant circumstances of the case
taking into consideration the volume and character of the waste and
use made of the sewer system to determine the sewer service charge
or rental according to the corresponding rates per 1,000 gallons provided
in this chapter.
(D) Deduct meters. If a person feels that a significant amount of metered
water does not reach the sanitary sewer, he or she can at his or her
own expense, with approval of the approving authority, install such
deduct meters as are necessary to calculate the volume of water not
discharged to the sanitary sewer. Metered water not discharged to
the sanitary sewers shall not be subject to sewer service charges.
Requests to install deduct meters must be made in writing to the approving
authority.
(E) Billings. The services provided for by this chapter shall be billed
each calendar quarter and the water utility billing procedures shall
apply to such bills.
(F) Delinquent payment; disconnection. If a person discharging wastes
into the city's sanitary sewer system does not procure his or
her sewer service supply from the city and becomes delinquent in payment
of sewer service charges, his or her connection with the city sewer
system will be severed and will only be reconnected at his or her
expense.
(G) Adjustments. The approving authority may recommend to the council
uniform rates for users where metered water is discharged in part
into the storm sewer and in part into the sanitary system; to interpret
and apply this chapter and to adjust charges and surcharges where
a literal application of the rules, rates and regulations of this
chapter would be inequitable, and to make and publicize such rules
as may be necessary and advisable to the more efficient operation
of this chapter.
[10-16-1990; 9-15-1992; 1-5-1999; 2016 Code]
(A) Sewer service charges are computed on the basis of sewer service
rates as may be set by resolution of the council from time to time.
(B) Measurement of flow; category A and B users.
(1)
Category A users. The volume of flow used for computing sewer
service charges for this category of users shall be the metered water
consumption of the user as shown in the records of meter readings
maintained by the water utility, within a 1,000 cubic foot annual
credit for non-consumptive uses including summer lawn watering computed
against the fixed customer charge.
(2)
Category B users. The volume of flow used for computing sewer
service charges for this category of users shall be the metered water
consumption of the user as shown in the records of meter readings
maintained by the water utility.
(C) Quarterly billing; category A and B users. All persons discharging
wastewater into the city sanitary sewer system under these categories
will be billed quarterly based on volume of flow used each quarter,
plus a fixed quarterly charge.
(D) Category C industrial wastewater discharge permit holders. All permit
holders discharging wastewater into the city sanitary sewer system
under this category will be billed quarterly based on volume of flow
discharged each quarter, in addition to a surcharge for treatment
of BOD exceeding 200 mg/l and suspended solids exceeding 250 mg/l,
plus a fixed quarterly charge.
