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 § 340-24 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.
Sewer service charge unit costs. The unit costs for the sewer service
charge shall be as stated in the Waterloo Utilities Fee Schedule.[1]
(1)

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)
Connection charges. The connection charges shall be as stated in
the City of Waterloo Fee Schedule.
(2)
Connection charges shall be determined as of the calendar year within which a building sewer is connected to a public sewer. For purposes of this § 340-23, 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 § 340-14 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 Subsection B(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.
