11.03 Building Sewer Connection. 

(1) Building Sewer Connection.  No unauthorized person shall uncover, make any connection or opening into, alter or disturb any public sewer or appurtenance without first obtaining a permit from the appropriate village official.  The owner or agent shall make application on a special permit provided by the village.  The permit shall be supplemented by any plans, specifications or special information considered pertinent by the village.  Permit fees shall be determined by separate village ordinances.

(2) A separate and independent building sewer shall be provided for every building.

(3) Existing building sewers may be used in conjunction with new structures only when they are found to conform to the requirements of this section.

(4) The size, slope alignment, materials of construction of a building sewer and the method to be used in excavating, placing of the pipe, joining, testing and backfilling the trench shall conform to the requirements of the plumbing code or other applicable rules and regulations of the village.

      (5) Roof leaders, subsurface drains, groundwater drains, foundation footing drains and other clear water drains shall be constructed and maintained, insofar as is practical, in such a fashion as to prevent clear water intrusion into the sanitary sewer system. 

      (a) All sources of clear water entry into the sanitary system existing at the time of the adoption of this section shall be illegal.

      b) If stormwater or clear water is being discharged into the sanitary system, either intentionally or as a cause of system degeneration, the village shall give the offending person 15 days notice to disconnect or to make sufficient repairs so as to eliminate the source of the clear water intrusion.  Failure to disconnect or to make such repairs shall authorize the village to cause disconnection or to make needed repairs and to assess the costs of such work against the property involved.


11.031 New Construction Inspection.  No connection with any sewer main or any part thereof shall be covered until the same has been inspected by the plumbing inspector or some other person authorized to make such inspection by the village board.  Before any such connection shall be covered, the person making the inspection on behalf of the village shall endorse the approval of the same upon the permit.  No connection shall be made to any sewer main except through a "Y" branch unless especially authorized by the plumbing inspector.  All connections shall be made in a workmanlike manner and to the satisfaction of the said inspector.  Connections to the main sewers shall be 6 inches in diameter, unless otherwise specially permitted or required by the plumbing inspector.


11.032 System Reconstruction.  The village has undertaken the systematic reconstruction of the public sanitary sewer system lying within the corporate limits. Metering records taken at the downstream end of the village system indicate the presence of an abnormal amount of clear water entry into the sanitary sewer system.  The presence of this clear water reduces available capacity to all system users, causes system overloads that may manifest themselves as basement flooding, causes a financial burden on the citizens of the village, and is a potential source of severe health hazards.  The village recognizes that its public sewer system has a finite life and in many cases has exceeded the useful life of the system.  The village also recognizes that private building sewers possess many of the same characteristics as the public system. (1) The village shall inspect all private connections to the public mains at the time of reconstruction of the public system. 

(a) Any existing private facility not meeting the requirements of this section shall be considered illegal.

(b) Prior to the actual reconstruction, each property owner shall be given written notice of the project.  Such notice shall be made no less than 30 days prior to commencement of the actual work.

(2) As the reconstruction progresses, the village shall inspect each private sewer connection for conformance with this section. 

(a) In the event that the private system meets the requirements of this section, the village shall reconnect the private system to the public system at an appropriate point near the right of way line. 

(b) In the event that the private sewer is found not to meet the requirements of this section, the village shall immediately notify the owner of the determined deficiency(ies)

(3) The owner shall, at the owner’s expense, make the necessary repairs to correct the deficiency(ies).  In all cases, the village shall supply an appropriate connection point as part of its work.   The owner may elect to: 

(a) make the repair(s). In doing so, the owner recognizes that all work must be done in strict conformance with all applicable local and state codes and in such a manner to correct the noted deficiency(ies).  All work needed to accomplish the repair shall be done at the expense of the owner. 

(b) contract with licensed contractor to complete the repair.  All work needed to accomplish the repair shall be done at the expense of the owner.

(c) have village contractors, if available, complete the repair. The village agrees, as part of any project, to request unit prices that will allow for the calculation of the cost of making the appropriate repair to the private building sewer. 

1.  Should the owner select this option, the owner will be charged the entire cost of making the repair. 

2.  The owner may elect to pay the entire amount upon completion of the work, or the owner may request that he be billed in the form of a special assessment on the owner’s tax bill according to section 10.10 of this code.


11.033 System Requirements. 

(1) All sanitary sewer mains and laterals, both public and private, shall be constructed and maintained in such a fashion that the effects of clear water on the system are held to an absolute minimum.

(2) All work, construction technique, and materials incorporated into the project shall be in strict conformance with state and local codes and the Standard Specifications for Sewer and Water Construction in Wisconsin, latest edition.

(d) 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.

(9) Pretreatment.  Where required, in the opinion of the Approving Authority, to modify or eliminate wastes that are harmful to the structures, processes or operation of the wastewater treatment works, the person shall provide at his/her expense such preliminary treatment or processing facilities as may be determined required to render his/her wastes acceptable for admission to the public sewers.

(10) Grease and/or Sand Interceptors.  Grease, oil and sand interceptors shall be provided as required by the state plumbing code (H62.11 and amendments) when they are necessary for the proper handling of liquid wastes containing floatable grease in ex­cessive amounts or any flammable wastes, sand, or other harmful ingredients; except that such interceptors shall not be required for private living quarters or dwelling units. 

(a) All interceptors shall be of a type and capacity approved by the plumbing inspec­tor and shall be located as to be readily and easily accessible for cleaning and inspection.

(b) In the maintaining of these in­terceptors, the owner(s) shall be responsible for the proper removal and disposal by appropriate means of the captured material and shall maintain records of the dates and means of disposal, which shall be subject to review by the Approving Authority. 

(c) Disposal of the collected materials performed by owner(s) personnel or currently licensed waste disposal firm or agent must be in accordance with currently acceptable DNR practice.

(11) Analyses.  All measurements, tests and analyses of the characteristics of water and wastes to which reference is made in this ordinance shall be determined in accordance with the latest edition of "Standard Methods for the Examination of Water and Wastewater", published by the American Public Health Associa­tion, and with the Federal Regulations 40 CFR 136, "Guidelines Establishing Test Procedures for Analysis of Pollutants".  Sampling methods, location, time, duration and frequencies are to be determined on an individual basis subject to approval by the Approving Authority. 

(a) Determination of the character and concentration of the indus­trial wastes shall be made by the person discharging them or his/her agent, as designated and required by the Approving Authority. 

(b) The village may also make its own analyses on the wastes and these determinations shall be binding as a basis for treatment service charges.

(12) Submission of Information.  Plans, specifications and any other pertinent information relating to proposed flow equali­zation, pretreatment or processing facilities shall be submitted for review to the Approving Authority prior to the start of their construction if the effluent from such facilities is to be discharged into the public sewers.

(13) Compliance.  The City Approving Authority must receive copies of all information submitted by sewer users to the Approving Authority within 5 days after the information is received by the Approving Authority.  The City Approving Authority must also be notified within 5 days of any permission granted and approvals given to sewer users or of other action taken by the Approving Authority regarding the control of industrial wastes directed to public sewers.


11.06 Basis for Sewer Service Charges.

(1)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 system and being served with water solely by the water utility, a sewer usage charge based on the volume of water used, as measured by the water utility water meter used upon the premises. In addi­tion, a minimum monthly (commercial) or quarterly (residential) service charge will be assessed each sewer user to cover administrative costs.

(2) Sewer Users Served By Private Wells.  If any person dis­charging sewage into the public sanitary sewer system procures any part or all of his/her water from sources other than the water utility, all or part of which is discharged into the public sanitary sewer system, the person shall have water meters in­stalled by the water utility at his/her expense for the purpose of determining the volume of water obtained from these sources. 

(a) The water meters shall be furnished by the water utility, in­stalled under its supervision, and maintained by the water utility.

(b) If it is not practical to meter a customer with a meter device, a monthly or quarterly charge will be calculated to recover the cost of sanitary sewer usage.

(3) Deduct Meters.  If a user feels that a significant amount of water metered does not reach the sanitary sewer due to lawn or garden watering, etc., he/she can at his/her own expense, through the Approving Authority, install a second water meter, or an additional metered service that would monitor this flow. 

(a) Charges for sewer use would be made based on the difference between the two meter readings.

(b) Refer to rate schedule for second water meter rental fee, PSC Rate File Schedule AM‑1 Amendment 19 or amendment in force at time of rental.

(c) Requests for a second meter or metered service must be made in writing to the Approving Authority.

(d) The water utility will charge for each meter a service charge set by the water utility to compensate for the cost of furnishing and servicing the meter.

(4) Inflow and Infiltration (I/I).  The village reserves the right to meter the wastewater of any customer reasonably believed to be generating I/I. 

(a) The ratio of water usage to wastewater flow will be determined using the three previous year’s of pumped water to metered wastewater flow.  The village shall bill the customer the higher of the pumped volume or water usage to wastewater flow ratio. 

(b) If it is determined through calculation ofwater usage to wastewater flow ratio that a customer’s actual wastewater flow is higher than the system ratio, the customer shall have a sewer meter installed at the customer’s expenses for the purpose of determining sewage volume for billing purposes.


11.07 Amount of Sewer Service Charges. 

(1) Basis for Service Charge.  Service charges are based on an annual revenue requirement consisting of operation and maintenance expenses, replacement costs, taxes and debt service. 

(a) These costs are to be recovered as follows:

1.  Village of North Fond du Lac treatment costs: Volume & Fixed charge

2.  Operation and maintenance expense:

Volume charge

3.  Replacement costs:  Volume charge

4.  Taxes:  Volume charge

5.  Debt Service:  Fixed charge

(b) Fixed Charge

1.  The fixed charge shall be a minimum monthly or quarterly charge for all users based on the user's meter size, meter equivalency ratio, monthly equivalency factor and benefited/non-benefited status.  The fixed charge shall recover annual debt service costs.  Annual debt service costs shall be allocated to benefited/non-benefited users based upon their proportionate share of total wastewater discharged to the sewer system.  a.  The fixed charge calculation is described below.  The fixed charge shall be revised to reflect the actual number and size of users and actual cost as part of overall rate adjustments. 

1.  Benefited Monthly Fixed Charge = (Meter Equivalency Ratio) x     

(Benefited Monthly Equivalency Factor)

      2.  Monthly Non-Benefited Fixed Charge = (Meter Equivalency Ratio) x

(Non-Benefited Monthly Equivalency Factor)

      3.  The meter equivalency ratios are as follows:

Meter Size       Meter Equivalency Ratio

5/8" & 3/4"      1.0

1"                     2.5

1-1/2"              5.0

2"                     8.0

3"                     15.0

4"                     25.0

6"                     50.0

8"                     80.0

(c) Volume Charge.  The volume charge shall be a monthly or quarterly charge based upon the volume and strength of wastewater discharged by a user to the sewer system.  The volume charge shall recover operation and maintenance expenses, replacement cost and taxes.  

1.  The normal domestic strength volume charge shall be revised to reflect actual volume cost no less often than biennially.  The normal domestic strength volume charge shall be as calculated:

Annual Operation, Maintenance, Replacement and Tax Expense ¸

Total Annual Wastewater Volume  = 

Normal Domestic Strength Volume Charge 

2.  The monthly volume charge shall be as calculated: 

a.  Normal Domestic Strength User Monthly Volume Charge =

Normal Domestic Strength User Charge x  Monthly Volume of Wastewater Discharged to the Sewer System

      b.  Greater Than Domestic Strength Users.  Charges to users discharging wastewater greater than normal domestic strength shall be assessed a surcharge based on the amount by which the wastewater exceeds normal domestic strength in accordance with the following formula:

Monthly Volume Charge = (NDS x V) + {(.00834 x V) x [(B$ x B#) + (S$ x S#) + (P$ x P#)]} Where

NDS = Normal domestic strength volume charge

V = Wastewater volume in CCF

B$ = Cost per pound of BOD above normal domestic strength

B# = Concentration of BOD from a user above normal domestic strength

S$ = Cost per pound of SS above normal domestic strength

S# = Concentration of SS from a user above normal domestic strength

P$ = Cost per pound of phosphorus above normal domestic strength

P# = Concentration of phosphorus from a user above normal domestic strength

.00834 = Conversion factor (mg/l to pounds)

      c.  In no event will a user pay less than the charge for normal domestic strength wastewater.

      d.   Flood Mobile Home Park.  Charges to Flood Mobile Home Park discharging wastewater not greater than normal domestic strength shall be equal to monthly volume charges designed for normal domestic users less the portion of the utility's cost of service related to clear water elimination funding.

(2)  Category A.  As previously defined as normal domestic strength wastewater having concentrations of biochemical oxygen demand (BOD) no greater than 250 mg/l, suspended solids no greater than 300 mg/l, and phosphorus no greater than 10 mg/l.  The sewer service charge for Category A wastewater is as follows:




Old Rate

New Rate

Fixed Customer Charges


Commercial 1/5/2010


Meter Charges


Pre-January 2010

Residential   1/5/2010



5/8 - 3/4 residential





1" - 1 1/4" residential






5/8 commercial





3/4" commercial





1" commercial





1 1/2" commercial





2" commercial





3" commercial





4" commercial





6" commercial





















*Note: Flood MHP receives Clearwater credit as part of rate per agreement



Mobile Home Parks














































(3) Category B is defined as wastewater having concentrations of BOD greater than 300 mg/l, suspended solids greater than 250 mg/l and/or phosphorus greater than 10 mg/l.  The sewer charge for Category B wastewater is as follows:

(a) Volume Charge       Same as Category A

(b) Customer Charges   Same as Category A

(c) A surcharge will be charged for the following as determined by the previous year’s annual true up as required by the 2000 Wastewater Agreement.  1.BOD (greater than 250 mg/l)

2.  SS (greater than 300 mg/l)

3.  Phosphorus (greater than 10 mg/l) 

(4) Reassignment of Sewer Users.  The Approving Authority will reassign sewer users into appropriate sewer service categories if wastewater sampling programs and other related information indicates a change of categories is necessary.
