§ 51.0091 Municipal Utility Services to Consumers Outside the City.

No property located outside the city limits shall be allowed to connect to municipal utility systems, except as approved by this section and §51.0091. Those persons desiring municipal utility service must first apply to the city for service and shall be required to (1) petition to be annexed into the city limits or (2) follow the requirements of §51.0092 of this Code. In the event the property owner outside the city limits petitions for annexation, utility services shall not be extended to such property until the annexation has been completed and the property is located inside the city limits.


The City may only allow connection to the utility systems of the City of Oronoco without annexation if there are specific circumstances that clearly demonstrate that annexation is not in the City’s public interest at the time of extension of utility services and provided that the property owners and township, prior to sewer extension, enter into agreements in the form acceptable to the City allowing for such contractual sewer extension. 

Such agreement with the property owners shall be in recordable form and be recorded by the City at the property owners expense and shall provide that the City may annex the property by ordinance at any time in the future and that the property owner waives any objection or right to contest such future annexation and will cooperate therewith and submit a written petition for annexation to the City at the time the City provides written notice thereof to the property owners. 

In making the determination to allow such utility connections the City Council shall make findings that: 1) annexation at the time of the request for utility service is not in the City’s interest, but that the City reserves the right to annex the property in the future; 2) the property owners and township have entered into the agreements required by the City; 3) the township has approved any required permits for the contractual extension of City sewer service to the requesting property; and 4) that there are unique circumstances to the property justifying pre-annexation extension of sewer service is appropriate and in the City’s best interest and for the benefit of the public, health, safety and welfare of the City and its taxpayers.

It shall be the responsibility of the consumer to notify the city to request a final meter reading at the time of the customer’s billing change.

§ 51.037 Termination or Suspension of Service.

The City may terminate or suspend any utility service to any property where the utility charge has become delinquent as provided herein, in which event such utility service shall not be restored until a service renewal charge of $100.00 has been paid in addition to any amount owed for service.

(A)       Grounds for Termination or Suspension. Any municipal utility may be terminated, discontinued, or suspended whenever:

(1)       The owner or occupant of the property served, or any person working on any connection with a municipal utility has violated any requirement of the City Code relative thereto; or

(2)       Any charge for a municipal utility service, or any other financial obligation imposed on the present or any former owner or occupant of the property served, is delinquent or unpaid; or

(3)       There is fraud or misrepresentation by the owner or occupant in connection with any application for service or delivery or charges therefore; or

(4)       The owner or occupant has permitted a person to subconnect another building or property to the owner or occupant's utility service; or

(5)       The owner or occupants tenders a payment to the city which is refused for non-sufficient funds, and after the city notifies the customer of this fact in writing the customer does not tender a valid payment within seven (7) days after the city mailed notice, including paying for any bank related fees which the city may incur as a result of the customer’s non-sufficient funds payment.

(B)       Procedure. Prior to the termination or suspension of any utility, the City shall forward to the owner and/or owner/consumer a notice of termination.

(1)       Notice. The notice of termination shall state the name and address of the owner and/or owner/consumer, the cause for the termination or suspension, and that utility service to the property will be terminated or suspended in ten (10) days unless such owner and/or owner/consumer shall remedy the cause for termination or suspension. The notice shall also state the owner and/or owner/consumer may, within ten (10) days after service of termination notice, demand, in writing, an appeal hearing before a hearing officer to be selected by the City for the purpose of determining whether the termination or suspension is proper.

(2)       Appeal hearing. In the event the owner and/or owner/consumer makes such a demand, in writing, upon the City Clerk, the City shall not terminate or suspend utility service until such time as the hearing examiner has determined the matter; provided that such hearing shall be held within twenty (20) days after demand therefore by the owner and/or owner/consumer.

(C)       Temporary Service Interruption of Service at Owner's Request. The fee for temporary disconnection of any utility shall be $0.00 and the fee for any subsequent reconnection shall be $100.00 per utility. When requested pursuant to this section, service shall be then turned off at the curb shutoff box, and the charges for consumption shall cease however the monthly cost of service for water, wastewater, and storm water will continue to be charged.

(1)       Any owner desiring a temporary disconnection with the city’s utility systems during a vacation or for any other reason, other than those listed in subsection (2), must serve written notice to the City Clerk/Treasurer at least seven days before the disconnection is desired. Temporary service interruption shall not extend beyond one (1) year.

(2)       In the event of a voluntary disconnection due to a mortgage foreclosure, impending bankruptcy, or other similar event which results in the customer ceasing to occupy the property, utility services will only be disconnected when the lender or other party temporarily responsible for management of the property pays the $100.00 fee to cover the cost for disconnection and subsequent reconnection prior to transfer of ownership of the property to any subsequent purchaser.

  • 51.038 Abandoned Service.

In the case of a utility service being abandoned for at least one (1) year, service will be cut off at a point determined by the City Engineer or designee and the meter removed. If the owner neglects or refuses to complete the required work the City shall cause said work to be done and bill the cost for said work to the owner. When new buildings are erected on the site of old ones and it is desired to increase or change the old water service, no connections with the mains shall be made until all the old service has been removed.


An excavation permit must be obtained to disconnect from the existing utility services. The fee for the permit shall be set by the City Council.

  • 51.0391 Financial Responsibility.

With the exception of all low pressure sewer connections constructed as part of the Phase 1A wastewater system improvements, all costs for maintenance and abandonment of utility service lines is the responsibility of the property owner, from the water main including the corporation and from the sewer main including the wye connection to a point of connection to the owner's building.  In the event the owner of the property does not occupy the property, but has rented the property out to a tenant, the owner of the premises shall be liable to the City for all utility services fees, charges, and fines. Any privately-owned low-pressure infrastructure and forcemain infrastructure existing at the time of construction of the Phase 1A wastewater system improvements shall be solely operated and maintained by the owner of such infrastructure.





Based on the information supplied by the property owner or available to the city, the city will make a determination whether a problem exists in that portion of the public utility service which is the city’s responsibility. If the problem appears to exist in the areas for which the city has no responsibility, the private owners will be responsible for correction of the problem. The owner shall be responsible for the costs of public utility service repairs within her or his property boundaries, except as provided herein.


The city will arrange for the investigative digging up and repair of any public utility service where the problem clearly exists within that area for which the city has responsibility. Unless it is clearly evident that the problem is the responsibility of the city, the excavation and repair will not be made until the property owner requests the city in writing to excavate or repair the service and agrees to pay the associated costs if the repair is found to be other than the city’s responsibility. The owner further agrees to waive a public hearing and be special assessed the cost of the excavation and repair if the problem is found to be other than the city’s responsibility. The city will make the determination for responsibility of the cost of investigation or repair. The matter of whether the dig up is done by city forces or contracted would depend on the urgency or need of repair and the availability of city forces to do the work. Recovery by the city for faulty construction will depend upon the circumstances and the decision of the City Council on the likelihood of recovery. 


In case of failure upon the part of any consumer or owner to repair any leak occurring in his or her service pipe within 24 hours after verbal or written notice, as determined by the city, the city may turn off the affected utility and the affected utility shall not be turned on until the leak has been repaired and a fee has been paid to the city.

§ 51.051 Service Connection Prior to Paving and Repaving.

Prior to street construction the City shall determine where new services are required or where existing services are in need of replacement or repair and shall notify the owner of the property affected that such construction or repair must be done within a specified time. If not made by such time, the City may cause said construction or repair made and assess the cost for the same against the benefited property.  

§ 51.052 utility Construction standards.

All installation, construction, and repair of service lines, accessories, and appurtenances thereto connected to municipal utilities shall conform to the requirements of the State Plumbing Code and the City requirements contained within the specifications promulgated by the City Engineers Association of Minnesota, which are incorporated into this Code by reference.

§ 51.053 SEPARATION.

No water service pipe or water connection shall be installed in the same trench or closer than ten feet horizontally to a sewer trench or drain laid, or to be laid, either in the street or in private property, except that the water pipe on private property may be in a common trench with a sewer drain which is of a material that is in conformance with the current State Plumbing Code, Minn. Rules Ch. 4715, as it may be amended from time to time.


Where it is desired to lay the water service pipe and the building sewer pipe in the same trench, or in separate trenches less than ten feet apart, the water service pipe shall be above the sewer pipe unless approved by the City Engineer. It shall be placed at least one foot above the sewer and on a solid shelf excavated at one side of the trench. The sewer pipe shall be of a material that is in conformance with the State Plumbing Code with tested water-tight joints. The water service pipe shall be water-tight and corrosion resistant. Type K-copper pipe ductile iron or approved equal water pipe with specially protected joints is acceptable for this construction. Ductile iron pipe shall conform to the American Water Works Association specifications for this pipe. Bell joint clamps with rubber gaskets are provisionally acceptable as extra protection for the joints on cast iron water pipe. In all cases, precautions shall be taken to assure a firm foundation for the pipes. The intervening space between the pipes shall be backfilled with compacted earth.


 In case the installation is on a surfaced street, all backfill materials shall be mechanically compacted in 12-inch layers to the density of the adjacent material in the roadway area and to the existing street grades in accordance with the State Department of Transportation Standards. Complete surface restoration shall be made at property owner’s expense.




§ 51.060 Water Meters.

All water meters shall be installed on the water valve in the house in accordance with the state’s Plumbing Code and any standards established by resolution of the City Council. 

(A)         Where a consumer has need for a larger line in addition to his or her domestic line, as in the case of a commercial consumer who needs a one-inch line for normal use and a six-inch or larger line for a fire sprinkler system, he or she will be permitted to run one line into the premises and “Y” off into two lines at the building. When this is done, the meter will be attached to the small or domestic line and a check valve, as well as one-inch detection meter, shall be put on the large line.

(B)         The city shall maintain and repair all meters when rendered unserviceable through ordinary wear and tear and shall replace them if necessary. When replacement, repair, or adjustment of any meter is rendered by the act, neglect (including damage from freezing or hot water backup) or carelessness of the owner or occupant of the premises and any expense caused the city thereby shall be charged against and collected from the water consumer.

(C)         A consumer may, by written request, have his or her meter tested by depositing an amount sufficient to cover the costs associated with testing the meter. In case a test should show an error of over 5% of the water consumed, a correctly registering meter will be installed, and the bill will be adjusted accordingly and the testing deposit refunded. This adjustment shall not extend back more than one billing period from the date of the written request.


Pursuant to the authority granted to the city by the provisions of M.S. § 444.075, subd. 3, as it may be amended from time to time, there is hereafter imposed upon each parcel of property or separate meter connecting to the municipal water supply system in the following described circumstances a connection charge in the amount set forth:

(A)         In the case of a parcel or meter served by facilities installed as a part of the municipal water system project that was constructed and financed in part with special assessments levied by the enactment of Resolution 09-13, and for which no special assessment was previously levied against the separate parcel or meter by Resolution 09-13, an amount of $6,216.43, plus simple interest from the date of October 21, 2009, calculated at the rate of 2% per annum;

(B)         In the case of a parcel or meter partially served by certain facilities installed by the developer, in conjunction with the development of the subdivision in which the parcel or meter is situated and for which certain water and sewer availability fees are also required to be paid to the city by the terms of an existing development agreement, an amount of $1,000.00, plus simple interest from the date of October 21, 2009, calculated at the rate of 2% per annum; and

(C)         In any other case, an amount determined as follows. The total area of all the property contained within the boundaries of the subdivision where the separate parcel or meter is situated, excluding roads and land dedicated for park purposes, shall be determined. The gross amount of the charge attributable to all property contained in the subdivision shall be calculated by multiplying this amount of area by $2,000.00 per acre if the calculation is performed in the year 2010. The specific amount attributable to each parcel shall then be determined by applying the ratio of the total land area of that parcel to the total land area of the subdivision and applying that ratio to the gross amount of charge attributed to all property. If the calculation is done to determine the amount of payment for a date subsequent to December 31, 2010, the amount of $2,000.00 shall be increased by an amount equal to 2% per annum for each year or portion of a year that has passed since the date of January 1, 2010.

(D)         The connection charge established herein shall be due and payable by the owner of the parcel or meter at the time of application for a building permit.

(B)         The City shall inspect the facilities of any user to ascertain whether the purposes of this chapter are being met and all requirements are being complied with. Persons or occupants of premises where wastewater is created or discharged shall allow the City ready access at all reasonable times to all parts of the premises for the purposes of inspection, sampling, and records examination. The City, Minnesota Pollution Control Agency (MPCA) and Environmental Protection Agency (EPA) shall have the right to set up on the user's property such devices as are necessary to conduct sampling, inspection, compliance monitoring and/or metering operations. Where a user has security measures in force which would require proper identification and clearance before entry into their premises, the user shall make necessary arrangements with any security guard so that upon presentation of suitable identification, the City, MPCA and EPA will be permitted to enter, without delay, for the purposes of performing their specific responsibilities.

(1)          In all cases the City's sampling data is final.

(2)          Representative samples of a user's industrial wastewater shall be collected on normal operating days and in accordance with guidelines established by the City. Industrial users subject to pretreatment standards shall sample in accordance with the pretreatment standards. Monitoring point(s) for industrial users who are subject to pretreatment standards shall be at a location before wastewater is mixed with other discharges or at a point where waste can be adequately monitored. Normal operating days shall be days when the user is engaged in operations that cause effluent discharge.

§ 51.087 Powers and Authority of Inspectors.

The City Engineer or other duly authorized employees of the City, bearing proper credentials and identification, shall be permitted to enter all properties for the purpose of inspection, observations, measurement sampling, and testing pertinent to the discharges to the City's sewer system in accordance with the provisions of this ordinance.

(A)         The City Engineer or other duly employees are authorized to obtain information concerning industrial processes which have a direct bearing on the type and source of discharge to the wastewater collection system. An industry may withhold information considered confidential; however, the industry must establish that the revelation to the public of the information in question might result in an advantage to competitors.

(B)         While performing necessary work on private properties, the City Engineer or other duly authorized employees of the City shall observe all safety rules applicable to the premises established by the company owning the property being inspected, and the company shall be held harmless for injury or death to the City employees and the City shall indemnify the company against loss or damage to its property by City employees and against liability claims and demands for personal injury or property damage asserted against the company and growing out of the gauging and sampling operation, except as such may be caused by negligence or failure of the company to maintain safe conditions.

(C)         The City Engineer or other duly authorized employees of the City bearing proper credentials and identification shall be permitted to enter all private properties through which the City holds a duly negotiated easement or sewer maintenance agreement for the purposes of, but not limited to, inspection, observation, measurement, sampling, repair, and maintenance of any portion of the wastewater facilities lying within said easement. All entry and subsequent work, if any, on said easement, shall be done in full accordance with the terms of the duly negotiated easement pertaining to the private property involved.

§ 51.088 Pretreatment.

Users shall provide necessary wastewater treatment as required to comply with this ordinance and shall achieve compliance with all national categorical pretreatment standards within the time limitations as specified by the Federal pretreatment regulations of this ordinance.

(A)         Any facilities required to pre-treat wastewater shall be provided, operated, and maintained at the user's expense. Detailed plans showing the pretreatment facilities and operating procedures shall be submitted to the City before construction of the facility. The review of such plans and operating procedures will in no way relieve the user from the responsibility of modifying the facility as necessary to produce an effluent acceptable to the City under the provisions of this ordinance or constitute a representation by the City that such plans will cause compliance or work in conjunction with the user's facility. Any subsequent changes in the pretreatment facilities or method of operation shall be reported to and be acceptable to the City prior to the user's initiation of the changes.

(B)         Any user subject to a national categorical pretreatment standard, after the compliance date of such pretreatment standard, or, in the case of the commencement of a new discharge to the wastewater treatment system, shall submit to the City during the months of June and December, unless required more frequently in the pretreatment standard established by the City, a report indicating the nature and concentration of pollutants in the effluent which are limited by such pretreatment standards. In addition, this report shall include a record of all daily flows which during the reporting period exceeded the average daily flow reported in the user's permit application or prior monitoring reports. The City may agree to alter the months during which the above reports are to be submitted.

(C)         Within ninety (90) days following the date for final compliance with applicable pretreatment standards, or, in the case of the commencement of a new discharge to the wastewater treatment system, any user subject to pretreatment standards and requirements, shall submit to the City a report indicating the nature and concentration of all pollutants in the discharge from the regulated process which are limited by pretreatment standards and requirements and the average and maximum daily flow for these process units in the user's facility which are limited by such pretreatment standards or requirements. The report shall state whether the applicable pretreatment standards or requirements are being met on a consistent basis and, if not, what additional operation and maintenance and/or pretreatment is necessary to bring the facility into compliance with the applicable pretreatment standards or requirements. This statement shall be signed by the user and certified to by a qualified registered professional engineer.

§ 51.089 Slug or Accidental Discharge.

Sludges, floatings, skimmings, and other undissolved particles generated by an industrial or commercial pretreatment system shall not be placed into the City's wastewater treatment system. Such sludges shall be contained, transported, and disposed of in accordance with all federal, state, and local regulations.

(A)         Each user shall provide protection from accidental discharge of substances regulated by this ordinance. Where necessary, facilities to prevent accidental discharge of prohibited materials shall be provided and maintained at the user's own cost and expense. Detailed plans showing facilities and operating procedures to provide this protection shall be submitted to the City for review and shall be approved by the City before construction of the facility.

(B)         Review and approval of such plans and operating procedures shall not relieve the user from the responsibility to modify the user's facility as necessary to meet the requirements of this ordinance. Users shall notify the Wastewater Treatment Plant immediately upon having a slug or accidental discharge or substances or wastewater in violation of this ordinance in order to enable counter-measures to be taken by the City to minimize damage to the wastewater treatment system and the receiving waters. Such notifications will not relieve users of liability for any expense, loss, or damage to the wastewater treatment system or treatment process, or for any fines imposed on the City on account thereof under any state or federal law. A notice shall be permanently posted in a prominent place advising employees whom to call in the event of a slug or accidental discharge. Employers shall ensure that all the employees who may cause or discover such a discharge are advised of the emergency notification procedure.  

(C)         Approval of plans and procedures made under this section shall not constitute any representation that such plans and procedures will correct a problem or operate in any given manner.

    (D)     The City shall be immediately notified of an accidental discharge by telephoning the City Clerk or Deputy City Clerk at the City Hall general telephone number from Monday through Friday. On weekends and holidays, in addition to notification not city Hall notice shall be made to the City Engineer and City Public Works Director at the telephone numbers or mails listed on the City of Oronoco official website.   


The City may immediately suspend the wastewater treatment service of a user and/or a wastewater discharge permit (after formal notice to the discharger) when such suspension is necessary, in the opinion of City, in order to stop an actual or threatened discharge which presents or may present an imminent or substantial endangerment to the health or welfare of persons, to the environment, or to the wastewater treatment system, or would cause the City to violate any condition of its NPDES or disposal system permit.

(A)         Any user notified of a suspension of the wastewater treatment service and/or the wastewater discharge permit shall immediately stop the discharge.

(B)         In the event of a failure of the user to comply voluntarily with the suspension order, the City may take such steps as it deems necessary, including immediate severance of the sewer connection, to prevent or minimize damage to the wastewater treatment system or endangerment to any individuals.

(C)         The City will reinstate the wastewater discharge permit and/or the wastewater treatment service upon proof of the elimination of the non-complying discharge and payment to the City of the City's costs of terminating and restoring service.

(D)         A detailed written statement submitted by the user describing the causes of the slug or accidental discharge and the measures taken to prevent any future occurrence shall be submitted to the City within fifteen (15) days of the date of occurrence.

§ 51.0892 Revocation of Permit.

In accordance with the procedures herein, the City may revoke the permit of any user which fails to factually report the wastewater constituents and characteristics of its discharge; which fails to report significant changes in wastewater constituents or characteristics; which refuses reasonable access to the user's premises for the purpose of inspection or monitoring or for violation of conditions of its permit, this ordinance, or applicable state and federal regulations, or where continued discharge at the levels set forth in the permit would adversely impact the wastewater treatment facility or the City's compliance with applicable permits or laws and regulations governing the wastewater treatment facility.

(A)         Notification of Violation. Whenever the City finds that any user has violated or is violating the requirements of this chapter, its wastewater discharge permit or any prohibition, limitation or requirement contained herein, the City may serve upon such user a written notice stating the nature of the violation. Within thirty (30) days of the date of the notice, unless a shorter time frame is necessary due to the nature of the violation, a plan for the satisfactory correction thereof shall be submitted to the City by the user and such plan shall be implemented within the same time period.  

(B)         Appeals. Any person aggrieved by any notice or order of the City issued under subsection (A) may file a petition for review of such notice or order with the City Clerk within ten (10) days after the service of the order or notice. The petition shall contain the name of the petitioner, the petitioner's address, location of the property subject to the order or notice and disclose petitioner's interest in the property.

(C)         Hearing scheduled. Upon receipt of the petition, the City Clerk shall set a date for a hearing and give the petitioner at least five (5) days' prior written notice of the date, time, and place of the hearing.
