backfilling the trench, shall all conform to the requirements of the
building and plumbing code 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 WPCF Manual of Practice No. 9 shall apply.
E.
Building 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 wastewater carried
by such building drain shall be lifted by an approved means and discharged
to the building sewer.
F.
Storm- and groundwater drains.
(1)
No person shall make connection of roof downspouts,
exterior foundation drains, areaway drains or other sources of surface
runoff or groundwater to a building sewer or building drain which
are connected directly or indirectly to a public sanitary sewer.
(2)
Any person in violation of this section shall disconnect
all downspouts, groundwater drains, etc., no later than sixty days
from the date of an official written notice by the approving authority.
If any person fails to comply after the expiration of the time provided,
the approving authority may cause disconnection to be made.
G.
Conformance to plumbing codes. The connection of the
building sewer into the public sewer shall conform to the requirements
of the building and plumbing code or other applicable rules and regulations
of the City or the procedures set forth in appropriate specifications
of the ASTM and the WPCF 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.
H.
Plumbers. No plumber, pipe fitter or other person
will be permitted to do any plumbing or pipe fitting work in connection
with the collection system without first receiving a license from
the State of Wisconsin and posting a bond of $1,000 with the City
of Manawa, except in cases where state law permits building owners
to do their own work without being licensed.
I.
Inspection of connection. The applicant for the building
sewer permit shall notify the approving authority when the building
sewer is ready for inspection and connection to the public sewer.
The connection shall be made under the supervision of the approving
authority.
J.
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.
K.
Installation of building sewers. All building sewers
on private property will be installed in accordance with ILHR 83,
Private Sewage Systems; specifically Section ILHR 83.21, Building
Sewers and Drains. Per Section ILHR 83.21, all building sewers will
be inspected. The building sewer and/or private interceptor main sewer
shall be inspected upon completion of placement of the pipe and before
backfilling; and tested before or after backfilling.
L.
Excavations.
(1)
In making excavations in streets or highways for laying
building sewers or making repairs, the paving and earth removed must
be deposited in a manner that will occasion the least inconvenience
to the public.
(2)
No person shall leave any such excavation made in
any street or highway open at any time without barricades; and during
the night, warning lights must be maintained at such excavations.
(3)
In refilling the opening, after the building sewers
are laid, the earth must be laid in layers of not more than 12 inches
in depth, and each layer thoroughly compacted to prevent settling.
This work, together with the replacing of sidewalks, gravel and paving,
must be done so as to make the street as good, at least, as before
it was disturbed, and satisfactory to the City and county. No opening
of the streets for tapping the pipes will be permitted when the ground
is frozen, except in emergencies.
(4)
A permit from the approving authority or other appropriate
governmental body shall be obtained prior to excavating in any street,
alley or other public way. Such permit shall be obtained and exhibited
to the City Clerk before a connection permit will be issued.
M.
Tapping the mains.
(1)
No person, except those having special permission
from the approving authority, or persons in their service and approved
by them, will be permitted under any circumstances to tap the mains
or collection pipes. The kind and size of the connection with the
pipe shall be that specified in the permit or order from said City.
(2)
Pipes should always be tapped on the top, and not
within 15 inches (38 cm) of the joint, or within 36 inches (90 cm)
of another lateral connection.
(3)
All connections to existing sewer mains shall be made
with a saddle T or Y fitting set upon a carefully cut opening centered
on the upper quadrant of the main sewer pipe and securely strapped
on with corrosion-resistant straps or rods, or with solvent welded
joints in the case of plastic pipe.
A.
Mandatory hookup.
(1)
The owner of each parcel of land adjacent to a sewer
main on which there exists a building usable for human habitation
or in a block through which such system is extended shall connect
to such system within 90 days of notice in writing from the City.
Upon failure to do so, the City may cause such connection to be made
and bill the property owner such costs. If such costs are not paid
within 30 days, such notice shall be assessed as a special tax lien
against the property, all pursuant to W.S.A. s. 281.45; provided,
however, that the owner may within 30 days after the completion of
the work file a written request with the utility stating that he cannot
pay such amount in one sum and ask that there be levied in not to
exceed five equal installments, and that the amount shall be so collected
with interest at the rate of 6% per annum from the completion of the
work, the unpaid balance being a special tax lien, all pursuant to
W.S.A. s. 281.45.
[Amended 1-3-2000]
(2)
In lieu of the above, the utility at its option may
impose a penalty for the period that the violation continues, after
10 days' written notice to any owner failing to make a connection
to the sewer system, of an amount equal to 150% of the average residential
charge for sewer service payable quarterly for the period in which
the failure to connect continues, and upon failure to make such payment
said charge shall be assessed as a special tax lien against the property,
all pursuant to W.S.A. s. 281.45.
[Amended 1-3-2000]
(3)
This chapter ordains that the failure to connect to
the sewer system is contrary to the minimum health standards of said
City and fails to assure preservation of public health, comfort and
safety of said City.
B.
Maintenance of services.
(1)
The utility shall maintain sewer service within the
limits of the City for the street mains and sewer laterals, without
expenses to the property owner, except when they are damaged as a
result of negligence or carelessness on the part of the property owner,
a tenant or an agent of the property owner. All sewer services from
the point of maintenance by the system to and throughout the premises
must be maintained free of defective conditions, by and at the expense
of the owner or occupant of the property.
(2)
When any sewer service is to be relaid and there are
two or more buildings on such service, each building shall be disconnected
from such service and a new sewer shall be installed for each building.
C.
Application to connect proposed new wastewater system.
(1)
Any person located within the corporate limits of
the City desiring to connect a proposed new wastewater system to the
wastewater treatment works shall make a written application to the
approving authority for permission to make such connection or use.
The application shall include a statement of the location or locations
at which it is desired to connect and a statement of the character
of the wastewater to be transmitted.
(2)
The City shall select an engineering consultant to
design all proposed wastewater systems. All costs and expenses incident
to the design and bidding, including engineering, permits and other
fees associated with the connection or hookup to the wastewater collection
system, shall be borne by the developer requesting the extension.
Prior to the design of a sewer extension, the developer shall secure
and furnish proof of an escrow account for the estimated amount of
the design costs, the amount to be determined by the City. The account
shall be so arranged and an escrow agreement executed between the
developer, the bank, the approving authority to allow the latter to
withdraw amounts from the account. The account shall be sufficient
to cover payments to all parties under contract with the City for
the design of the wastewater system. This money will not be refunded
if the project does not proceed to construction.
D.
Alterations.
(1)
Alterations to existing wastewater systems connected
to the wastewater treatment works shall be treated as proposed new
wastewater systems. The approving authority may modify this provision
if the sewer connection is not directly connected to an approving
authority sewer and provided that the person has previously presented
and has had approved a general overall sewer plan. If such a modification
is made, it will be done in writing and must be kept on file by the
person to which it applies.
(2)
After sewer connections have been made in a building
or upon any premises, no plumber shall take any alterations, extensions
or attachments unless the party ordering such work shall exhibit the
proper permit.
E.
Permit to connect. Prior to permitting such connection
or use, the approving authority may investigate, or cause to be investigated,
the wastewater system for which such connection or use is requested.
If the approving authority finds such system to be in a satisfactory
condition, it will grant a permit for such connection or use. If the
approving authority finds such system to be defective in operation,
construction, design, or maintenance, the approving authority will
so notify the applicant and will advise him that, upon completion
of specified alterations, new construction or changes in supervision
or operation, a permit will be granted. Should the plans or specifications
not be approved, one copy will be returned to the applicant who will
be informed as to the reason for nonapproval.
F.
Reserve capacity. Prior to permitting any connection
or use of the treatment works, the approving authority shall ascertain
that all downstream sewers, interceptors, lift station, forcemains,
and treatment works have sufficient reserve capacity for volume, suspended
solids and BOD5 to assure adequate collection
and treatment of the additional wastewater contributed to the wastewater
treatment works. The approving authority reserves the right to refuse
a connection or use permit if the requirements for this subsection
cannot be met with the granting of the permit.
G.
Inspections and supervision during construction. During
the construction of any wastewater system which the approving authority
has approved, the approving authority may, from time to time, inspect
the same to see that said work is being done in accordance with the
approval plans and specifications. Failure to make such inspections
shall not nullify the rights of the approving authority to require
reconstruction should nonadherence to approved plans be subsequently
discovered. Every person in the construction of laterals or wastewater
systems, within its jurisdiction, shall require that such construction
be under the direction of a Wisconsin registered professional engineer
or licensed master plumber, if plan approval was obtained under his
license. The engineer or master plumber shall keep accurate records
of the location, depth and length of the sewers as built, and of the
location of the Y-branches or slants.
H.
Permits not granted. Permits shall not be granted
for the connection of combined sewers to the interceptors or municipal
sewers. Permits shall not be granted for the connection of any proposed
or existing storm sewers to the approving authority wastewater treatment
works. Connection of catch basin or curb inlets to any sanitary sewer
directly or indirectly connected to the wastewater treatment works
is strictly prohibited.
I.
Physical connection. All proposed sewer connections
shall be planned to be made at a manhole with the flow lines of the
connecting sewer being at or below the manhole shelf, or the connection
shall be made through an approved drop. At least 24 hours before connection
is to be made, notice of such intent must be given to the approving
authority. When the actual connection is made, it must be done in
the presence of an approving authority inspector.
J.
Records. Records of connections to the wastewater
collection system shall be kept by the municipality in which such
connections are made, and such records shall be available for inspection
by the approving authority.
K.
User use only. No user shall allow others or other
services to connect to the wastewater collection system through his
building sewers and building drains.
L.
User to permit inspection. Every user shall permit
the Utility, or its duly authorized agent, at all reasonable hours
of the day, to enter their premises or building to examine the pipes
and fixtures, and the manner in which the drains and sewer connections
operate; and they must at all times, frankly and without concealment,
answer all questions put to them relative to its use.
M.
Utility responsibility. The Utility and its agents
and employees shall not be liable for damages occasioned by reason
of the breaking, clogging, stoppage or freezing of any building sewers
or building drains; nor from any damage arising from repairing mains,
making connections or extensions or any other work that may be deemed
necessary. The right is hereby reserved to cut off the water and sewer
service at any time for the purpose of repairs, or any other necessary
purpose, and permit granted or regulation to the contrary notwithstanding.
Whenever it shall become necessary to shut off the sewer service within
any district of the said City, the City shall, if practicable, give
notice to each and every consumer affected within said City of the
time when such service will be so shut off.
N.
User to keep in repair. All users shall keep their
own building sewers and building drains in good repair and protected
from frost, at their own risk and expense, and shall prevent any unnecessary
overburdening of the sewer system.
A.
Septic tanks and holding tanks prohibited. The maintenance
and use of septic tanks, holding tanks or other private disposal system
within the sewer service area of the City serviced by its wastewater
collection system are hereby declared to be a public nuisance and
a health hazard. The use of these systems is prohibited unless a special
permit is obtained from the approving authority. Upon abandonment
of the septic tank or holding tank, the tank shall be filled with
sand or gravel in a manner acceptable to the approving authority.
B.
Septic tank and holding tank disposal.
(1)
No person in the business of gathering and disposing
of septic tank or holding tank wastes shall transfer such material
into any disposal area or manhole located within the City of Manawa
boundaries unless a permit for disposal has been first obtained from
the approving authority. Written application for this permit shall
be made to the approving authority and shall state the name and address
of the applicant; the number of its disposal units; and the make,
model and license number of each unit. Permits shall be nontransferrable
except in case of replacement of the disposal unit for which a permit
shall have been originally issued. The permit may be obtained upon
payment of a fee. Annual fees shall be established by the approving
authority. Any applicant for a permit shall furnish a bond to the
City of Manawa in the amount of $5,000 to guarantee performance. The
bond shall be provided prior to the permit being issued. The time
and place of disposal will be designated by the approving authority.
The approving authority may impose such conditions as it deems necessary
on any permit granted. Bills shall be mailed on a monthly basis, and
if payments are not received in 30 days thereof, disposal privileges
shall be suspended.
(2)
Any commercial hauler of septic tank or holding tank
wastes agrees to carry public liability insurance in an amount not
less than $100,000 and to protect any and all persons or property
from injury and/or damage caused in any way or manner by any act,
or failure to act, by any of his employees. A certificate certifying
such insurance to be in full force and effect shall be furnished to
the approving authority.
(3)
Any wastes discharged into the treatment system shall
be of domestic origin and will comply with the provisions of any and
all applicable ordinances of the City of Manawa. A discharger shall
not deposit or drain any gasoline, oil, acid, alkali, grease, rags,
waste, volatile or inflammable liquids or other deleterious substances
into any manhole nor allow any earth, sand or solid material to pass
into any part of the wastewater system.
(4)
Any person or party disposing of septic tank or holding
tank wastes agrees to indemnify and save harmless the City of Manawa
from any and all liability and claims for damage arising out of or
resulting from work and labor performed.
A.
Willful, negligent or malicious damage. No unauthorized
person shall maliciously, willfully or negligently break, damage,
destroy, uncover, deface or tamper with any structure, appurtenance
or equipment which is a part of the wastewater facilities. Any persons
violating this provision shall be subject to immediate arrest under
a charge of disorderly conduct.
B.
Liability for losses. Any person who intentionally, negligently or accidentally violates any provisions of this chapter shall become liable to the City of Manawa or any downstream user, for any expense, loss or damage occasioned by reason of such violation which the City or any downstream user may suffer as a result thereof. This section shall be applicable whether or not a written notice of the violation was given as provided in § 259-10 and without consideration for any penalties which may be imposed for a violation of this chapter.
A.
Written notice of violation. Any person found to be
violating any provision of this chapter shall be served by the approving
authority with a written notice stating the nature of the violation
and providing a reasonable time for the satisfactory correction thereof.
The offender shall, within the period of time stated in such notice,
permanently cease all violations.
B.
Accidental discharge. Any person found to be responsible
for accidentally allowing a deleterious discharge into the sewer system
which causes damage to the treatment facility and/or receiving body
of water shall, in addition to a fine, pay the amount to cover damage,
both values to be established by the approving authority.
C.
Continued violations. Any person, partnership or corporation, or any officer, agent or employee thereof, who shall continue any violation beyond the aforesaid notice time limit provided shall, upon conviction thereof, pay a forfeiture of not less than $10 nor more than $2,500, together with the costs of prosecution. In default of payment of such forfeiture and costs, said violator shall be imprisoned in the Waupaca County Jail until such forfeiture and costs are paid, but not exceeding 90 days. This, however, shall not bar the approving authority from enforcing the mandatory hookup provision in § 259-7A or any other right the approving authority may have.
D.
Liability to City for losses. Any person violating
any provision of this chapter shall 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.
E.
Differences of opinion. The City of Manawa Attorney
shall arbitrate differences between the approving authority and sewer
uses on matters concerning interpretation and execution of the provisions
of this chapter by the approving authority.
F.
Damage recovery.
(1)
The City shall have the right to recover any expense
incurred by the utility for the repair or replacement of any property
owned by the City or utility damaged in any manner from the person
responsible for such damage.
(2)
Any user discharging toxic pollutants shall pay for
any increased operation, maintenance and replacement costs caused
by said discharge, in addition to any other charge or penalties provided
herein.
A.
Billing period. User charges for all customers shall
be billed on a quarterly basis.
B.
Payment. User charges shall be included as separate
items on the regular quarterly statement for water services or as
otherwise determined by the approving authority. User charges shall
be payable at the office of the approving authority or at any other
officially designated location at the same time that the water statements
become due, and payments for water service shall not be accepted without
full payment of the user charges.
C.
Penalties. Charges levied in accordance with this
chapter shall be a debt due to the City of Manawa. If the debt is
not paid within 20 days after it is due and payable, it shall be deemed
delinquent. There shall be an added penalty of 3% of the amount of
the quarterly bill. Charges and penalties shall constitute a lien
upon the property services and be recorded on the City's tax roll.
Change of ownership or occupancy of premises found delinquent shall
not be cause for reducing or eliminating these penalties.
D.
Notification. Each user shall be notified annually,
in conjunction with a regular bill, of the rate schedule attributable
to wastewater treatment services, including an explanation of the
charges.
E.
Billing. The property owner is held responsible for
all bills on premises that he owns. All bills and notices of any nature,
relative to the sewer service, will be addressed to the owner and/or
occupant and delivered to the addressee by first class mail.
F.
Failure to receive bill, no penalty exemption. Every
reasonable care will be exercised in the proper delivery of bills.
Failure to receive a bill, however, shall not relieve any person of
the responsibility for payment of user charges within the prescribed
period, nor exempt any person from any penalty imposed for delinquency
in the payment thereof.
G.
Delinquent bills. On October 15 in each year, notice
shall be given to the owner or occupant of all lots or parcels of
real estate to which service has been furnished prior to October 1
and payment for which is owing and in arrears at the time of giving
such notice. The Utility shall furnish the City Treasurer with a list
of all such lots or parcels of real estate, and the notice shall be
given by the Utility. Such notice shall be in writing and shall state
the amount of such arrears, including any penalty assessed pursuant
to the rules of such Utility; that unless the same is paid by November
1, the same will be levied as a tax against the lot or parcel of real
estate to which service was furnished and for which payment is delinquent
as above specified. Such notice may be served by delivery to either
such owner or occupant personally, or by letter addressed to such
owner or occupant at the post office address of such lot or parcel
of real estate. Each such delinquent amount, including such penalty,
shall thereupon become a lien upon the lot or parcel of real estate
to which the service was furnished and payment for which is delinquent.
All proceedings in relation to the collection of general property
taxes and to the return and sale of property for delinquent taxes
shall apply to said tax if the same is not paid within the time required
by law for payment of taxes upon real estate.
A.
No fine shall be levied under § 259-11C and no indemnity shall be assessed under § 259-11G except upon due hearing regarding the violation permitting the alleged violator to show cause, if any there be, before the approving authority why a fine should not be imposed pursuant to § 259-11C or why assessment should not be made pursuant to § 259-11G or any combination of the two. An order for hearing issued by the approving authority shall be served upon the alleged violator in the same manner as a summons is served under Wisconsin statutes, and it shall be returnable before the approving authority at a time certain not sooner than five days after service.
B.
The order for hearing may contain ex parte interim
orders pendente lite as may appear (by testimony or appropriate documents
filed with the approving authority, or both) necessary to protect
the public health, welfare or safety on an emergency basis, including
but not limited to temporary termination of service.
C.
Testimony taken before the approving authority will
be under oath or affirmation and recorded stenographically. A transcript
thereof will be made available to any member of the public, including
but not limited to any party to the hearing, upon payment of the usual
charges therefor.
D.
After the approving authority has reviewed the evidence, it may impose any fine authorized by § 259-11C or assess any indemnity authorized by § 259-11G, as, in the judgment of the approving authority, is warranted by the evidence. The approving authority may issue such further orders and directives as it deems appropriate, including orders requiring the violator to pay the full costs of the proceedings, including the City's technical, administrative and other costs in developing its proofs and reasonable attorney fees.
E.
A violator may avoid the hearing herein provided by written waiver stipulating guilt presented to the City at least 24 hours prior to the hearing time. The approving authority will meet nevertheless, will make no stenographic transcript, will give the violator an opportunity to be heard in mitigation and may then act in accordance with Subsection D of this section, except that the violator shall not be required to pay any costs of the proceeding.
The Common Council of the City of Manawa, through
its duly qualified officers, reserves the right to amend this chapter,
in part or in whole wherever it may deem necessary, but such right
will be exercised only after due notice to all persons concerned and
proper hearing on the proposed amendment.
The City of Manawa shall conduct an annual audit,
the purpose of which shall be to reestablish the equity and adequacy
of the user charges relative to changes in system operation and maintenance
costs.
A.
The following methodology is to be utilized by the
City of Manawa to determine the user charges for its customers.
B.
User charges must be reviewed annually and updated
as required to maintain sufficient revenues and maintain a proportional
distribution of costs among users and user classes. Regardless of
the frequency of revision, this methodology can be utilized at any
time. It should be noted that the values and calculations presented
in this document are for example purposes only.
C.
The purpose of this methodology is to ensure that
each user class pays its proportionate share of operation and maintenance
(including replacement) and other costs of operating the wastewater
treatment facility and wastewater collection system within the City
of Manawa service area. Following the completion of the annual review,
the City shall revise as necessary the charges for users and user
classes to maintain the proportionate distribution of costs among
users and user classes, generate sufficient revenue to pay the total
costs necessary for the proper operation (including maintenance and
replacement) of the treatment facility and collection system and to
apply excess revenues collected from a class of users to the costs
of operation attributable to that class for the next year and adjust
the rates accordingly.
A.
The purpose of the fixed charge is to recover the
capital costs incurred by the City of Manawa in the construction of
the wastewater treatment facility and collection system and any subsequent
modifications.
B.
The base fixed charge for all users shall be based
on the size of their water meter(s) in accordance with the schedule
below. Unmetered residential users shall be considered to be equivalent
to a three-fourths-inch meter. Other unmetered users will be evaluated
on a case-by-case basis by the approving authority.

Sewers used have been found to comprise meter equivalents
based on water meter sizes, as shown in Schedule 1. The typical residence
consists of one meter equivalent and will be charged $44.36 per quarter
or $177.44 per year. Calculation of the charges for various meters
and a summary of charges for all meters are presented in Schedule
Nos. 1, 2 and 3.[2]
[Amended 3-1-2010 by Res. No. 2010-2]
[2]
Editor's Note: Said schedules are available
from City offices.
A.
Operation and maintenance charge.
(1)
The cost to operate and maintain the wastewater treatment
facility and wastewater collection system must be paid by the users
of the system in approximate proportion to their usage. Where metered
water usage data is available, this can be used as a basis for equitable
sewer user charges. However, when information on actual usage is not
available, user charges must be based on estimated wastewater contribution,
using similar land and building uses in other communities as a guide.
(2)
Operation and maintenance costs are defined, per the
requirements of the Clean Water Fund loan program, to include replacement
costs. That is, a separate fund must be established in which moneys
will be accumulated to pay the cost "for obtaining and installing
equipment, accessories or appurtenances which are necessary to maintain
the capacity and performance (of the wastewater works) during (its)
service life." The Replacement Fund budget shown includes an annual
contribution of $8,094 for this purpose (refer to Schedule 5).
(3)
The cost of operating and maintaining the treatment
works will vary from year to year. The projected total cost for the
next year of operation is $343,180.
[Amended 3-1-2010 by Res. No. 2010-2]
(5)
Discharges of "normal strength wastewater," defined
as not exceeding 275 milligrams per liter (mg/L) concentration of
BOD5, 225 mg/L concentration of SS and 7 mg/L
concentration of phosphorus as determined from monitoring records,
will pay on a unit basis of $4.11 per 1,000 gallons.
[Amended 3-1-2010 by Res. No. 2010-2]
(6)
Customers discharging wastewaters of greater than
normal strength must pay a surcharge on the additional loadings. The
charge for each customer would be determined from the formula presented
below:
|
C = F + $2.30 x V + .00834 x V x [($0.241 x
B) + ($0.362 x S) + ($4.491 x P)]

Unmetered users must pay a flat rate charge based
on average water usage. The flat rate charge for unmetered users is
$29.00 as determined in Schedule 7. The total charge for unmetered
users equals the volume charge plus the fixed charge for an unmetered
user.
