or its duly authorized representatives at all times. Every care shall
be exercised in the collection of samples to ensure their preservation
in a state comparable to that at the time the sample was taken.
G.
Pretreatment. Persons discharging industrial wastes
into any public sewer may be required to pretreat such wastes if the
approving authority determines pretreatment is necessary to protect
the wastewater treatment facilities or prevent the discharge of incompatible
pollutants. In that event, such person shall provide, at his expense,
such pretreatment or processing facilities as may be determined necessary
to render wastes acceptable for admission to the sanitary sewers.
H.
Grease, oil and sand interceptors. Grease, oil and
sand interceptors shall be provided when, in the opinion of the approving
authority, they are necessary for the proper handling of liquid wastes
containing floatable grease in amounts in excess of those specified

Test Procedures For Analysis of Pollutants, as amended from time to
time. Sampling methods, location, time, durations and frequencies
are to be determined on an individual basis subject to approval by
the approving authority.
(2)
Determination of the character and concentration of
the industrial wastes shall be made by the person discharging them
or the person's agent, as designated and required by the approving
authority. The approving authority may also make its own analyses
on the wastes, and these determinations shall be binding as a basis
for sewer service charges.
J.
Submission of information. Plans, specifications and
any other pertinent information relating to proposed flow equalization,
pretreatment or grease and/or sand interceptor facilities shall be
submitted for review and approval of the approving authority prior
to the start of their construction if the effluent from such facilities
is to be discharged into the public sewers. No construction of such
facilities shall commence until said approval has been granted.
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.
(1)
If any person discharging wastewater into the public
sanitary sewers procures any part or all of his water from sources
other than the Water Utility, all or part of which is discharged into
the sanitary sewers, the person shall have water meters installed
by the Water Utility at the person's expense for the purpose of determining
the volume of water obtained from these sources. Where sewer meters
are already installed, new water meters will not be required. The
water meters shall be furnished by the Water Utility and installed
under its supervision, all costs being at the expense of the person
requiring the meter.
(2)
The Water Utility shall charge for each meter a rental
charge set by the Water Utility to compensate for the cost of furnishing
and servicing the meter. The rental charge shall be billed at the
time the sewer service charge is billed.
C.
Deduct meters. If a user feels that a significant
amount of metered water does not reach the sanitary sewer, the user
may avail himself of one of the following options:
(1)
The user may request the approving authority to have such additional meters or metered services installed as are necessary to calculate the volume of water not discharged to the sanitary sewer, i.e., a "deduct" meter, or he may request the approving authority to have a meter installed to measure the actual amount of sewage discharged to the sanitary sewer, i.e., a "sewage" meter. A request for a second meter or metered services must be made in writing to the approving authority. In the event the approving authority agrees to such installations, the customer shall be charged all costs attendant thereto, including but not limited to a meter yoke for each meter to be installed by a licensed plumber, meter rental (the meter will be owned by the City and subject to access and inspection by the City personnel at all reasonable times) in an amount set annually by the approving authority, remote reading devices if necessary, and labor and miscellaneous parts and supplies. No provision shall be made nor shall any means be taken to route water from any "deduct" meter to the customer's general distribution system. In addition to the general penalties set forth in § 340-22 of this article, any violation of this section shall result in nullification of the deduct readings and removal of the deduct meter.
(2)
In the event it is physically impractical or impossible
to install metering equipment, he may request the approving authority
to take such means as it deems necessary to formulate an estimate
of the amount of water not being discharged into the sanitary sewerage
system or, conversely, the amount of actual sewage discharged thereto.
(3)
Neither of the options set forth in this section shall
be applicable or available to customers for reasons which are attendant
to use of water for the filling of pools or watering of lawns and
outdoor greenery. Such seasonal use of water that does not reach the
sewer system has been figured into the rates for the third quarter.

A.
Introduction and authority.
(1)
It is the general policy of the City that new users
located within the geographic boundaries of the City reasonably participate
in the cost of the City's existing wastewater treatment facilities
at the time their lands actually receive sanitary sewer service. Wastewater
facilities are generally defined as all interceptors and related facilities
such as manholes and appurtenances, pumping stations, force mains
and the wastewater treatment plant. In determining what constitutes
reasonable participation toward such cost, the City is guided by the
principle that the area to be served shall bear its proportionate
share of such costs. The costs of the wastewater facilities in which
new users are required to participate are:
(2)
Wastewater facilities have a significant physical
life. This requires that they be constructed of sufficient capacity
to serve present users and future users. It is economical to construct
wastewater facilities with excess capacity. Therefore, it is reasonable
that future users, as well as present users, pay the total cost of
the wastewater facilities that serve them. The investment in excess
capacity is made for the future user's benefit; and is not available
for other uses by the City. Because future users make no payment until
they connect to the sanitary sewers, only a part of the total cost
of the wastewater facilities can be collected when said facilities
are first placed in service. Accordingly, the costs to be recovered
at the time of initial connection to the wastewater facilities should
be recovered through a connection charge. This connection charge is
enacted pursuant to § 66.0821(4), Wis. Stats.
B.
Amount of connection charge.
(1)
Previously, the City completed a significant and substantial
expansion of the wastewater facilities in order to accommodate improved
service to the areas it serves and to accommodate growth and development
therein. The City has directed its outside consultants to prepare
a "Sewer Connection Fee Report," which report examines a number of
methodologies for determining a connection fee. The City elects to
impose a connection charge by adopting the "Cost of Plant Methodology."
Therefore, effective as of September 1, 2007, a connection charge
is hereby established, to be in the amount of $746 per ERU. This connection
charge shall be adjusted annually, commencing on January 1, 2008,
and each calendar year thereafter; and the payment thereof is a condition
precedent to the provision of sanitary sewer service to the property
in question.
(2)
Connection charges shall be determined as of the calendar year within which a building sewer is connected to a public sewer. A "building sewer" is defined as the sewer pipe extension from a building drain to the public sewer. It is sometimes referred to as a "house connection" or "building connection." A building drain is that part of the lowest horizontal piping of a drainage system which receives wastewater discharges from pipes located inside the walls of a structure and conveys it to the building sewer. For purposes of this § 340-21, the term "ERU" means a single-family dwelling unit having a single EWM.
(a)
The term "EWM" shall mean the number of equivalent
5/8-inch water meters serving the structure in question and is based
on the following:
|

(b)
Where a user does not have a water meter for
measuring the user's water consumption, or where a water meter does
not reasonably reflect the amount of corresponding wastewater discharges
from the structure/building in question, the Utility Superintendent
shall estimate the number and size of water meter(s) that would otherwise
be required to serve that user, based upon standard engineering practices,
and the equivalent water meters shall then be determined on that estimate.
(3)
Where a user discharges industrial wastes that are subject to the provisions of § 340-13 of this chapter, the City shall have the right and option to impose an additional industrial discharge fee directly upon such user in order to fairly and equitably recover capital costs associated with treating such industrial wastes. The industrial discharge fee shall recover a portion of capital costs associated with treating wastewaters that are not normal domestic strength; and such industrial discharge fee shall be in addition to the connection charges provided for in § 340-21B(1) above.
C.
Annual adjustment to connection charge. Effective
January 1, 2008, and each calendar year thereafter, the connection
charge shall be annually adjusted based upon changes to the "Engineering
News Record Construction Cost Index" (the "Index"), which Index most
closely reflects construction costs of the wastewater facilities.
The adjustment shall reflect changes to the Index during the period
of July 1 through June 30 of each year. The connection charge shall
be increased or decreased annually by the percentage increase or decrease
(rounded) in the Index, determined as of June of each year commencing
with the year 2008. By way of example only, if the Index in June of
2006 was 7629.95 and the Index for June 2007 is 8010.00, the changes
in the Index represent a percentage increase of 5.0% for the twelve-month
period of time (June 2006 to June 2007). Accordingly, the connection
charge would be increased by $37 (rounded) for an adjusted connection
charge of $783, rounded, for the year 2008. The connection charge
shall be in the amount so determined for the calendar year within
which the building sewer is connected to the sanitary sewer.
D.
Application of connection charge. In collecting the
connection charges, the following shall apply:
(1)
The connection charge is applicable to new users of
the wastewater facilities as well as existing users who increase their
wastewater discharges to the wastewater facilities.
(3)
Once paid, a connection charge shall never be refunded
or credited, even if the user/property in question changes its use
in such manner that fewer ERUs are applicable thereto. Under no circumstances
shall there ever be less than one ERU for each building sewer connection.
The Commission may at any time require a user to install appropriate
meters to determine whether or not increased wastewater flows have
or are occurring relative to the property in question.
(4)
The City may adopt uniform policies providing for
the waiver of connection fees, whenever the imposition thereof would
be unfair, arbitrary or unreasonable; and such policies shall be applied
by the Commission.
E.
Payment of connection charge. The connection charges
shall be paid by the user to the City by the end of the calendar month
following the month within which a building sewer has been connected
to a public sewer conveying wastewater to the wastewater facilities,
except as otherwise provided for herein. A penalty of 1% per month
shall be assessed on all connection charges not paid at that time;
and such penalty shall continue until payment is made in full. For
purposes of this section, connection fees are deemed to be a debt
due the City from the user. Delinquent connection charges shall be
collected in the same manner as delinquent sewer service charges.
C.
Accidental discharge. Any person found to be responsible
for accidentally allowing a deleterious discharge into the sewer system
which causes damage to the wastewater treatment facility and/or receiving
body of water shall, in addition to a forfeiture, pay an amount to
cover any damages, both values to be established by the approving
authority.
E.
Liability to City for losses. Any person violating
any provision of this article shall, in addition to any penalty or
forfeiture which may be assessed against him, become liable to the
City for any expense, loss or damage occasioned by reason of such
violation which the City may suffer as a result thereof.
