Other buildings and structures shall be assigned one unit for each one hundred thousand (100,000) gallons of flow annually which is estimated they will discharge; and commercial and industrial structures shall be assigned a minimum of one unit. Standard city trunk sanitary sewer connection charge unit for various commercial facilities shall be computed in accordance with current Metropolitan Waste Control Commission standards. (Amended Ord. 32, 11-25-1975; amd. 2003 Code) C. The City Council shall determine which type of facility and parameter shall apply for each sewer connection requested. The city trunk sewer connection charge for a facility not included in the above list will be determined by the City Council. A request for a trunk sewer connection charge unit determination should be made prior to the issuance of the building permit. D. Structures that contain two (2) or more facilities shall be charged a combined amount equal to the total sewer connection charge for each facility. E. The city trunk sewer connection charge unit shall be a whole number, with fractional portions resulting from calculations rounded to the nearest whole number. F. The trunk sewer connection fee shall be as set forth by ordinance1. (Amended Ord. 32, 11-25-1975; amd. 2003 Code) 1 See subsection 1-7-3J of this code. 10-3-3: SEWER RENTAL CHARGES 1: A. Rental Charge: All premises located within the corporate limits of the city served by the city sewer system shall pay a sewer rental fee to the city as set forth by ordinance, payable quarterly or monthly for each Sewer Availability Charge (SAC) unit. B. Schedule Of Charges: The sewer rental fee for residential dwellings with city water in place shall be based on the following schedule: 1. Residential Use: For each living unit, the sewer use charge shall be as set forth by ordinance, payable quarterly. 2. Nonresidential Use: a. Charges for nonresidential sewer use shall be based upon the number of residential equivalent connections (RECs) computed for each building or structure receiving municipal sewage service. Such computations are to be done as follows: building Sewer Availability Charge units (SAC units) x 100,000 gal. per yr. divided by 87,000 equals no. RECs. The charge per REC shall be as set forth by ordinance, payable quarterly. The city may require a nonresidential building user to provide a water meter, approved by the Public Utilities Department, that will accurately measure all water supplied to the premises. In February of each year, the meter readings shall be reviewed and one REC assigned to each 73,000 gallons of water consumed in the pervious one year period. If the number of RECs computed by reference to water usage varies from RECs computed by the above formula, the charges for that calendar year shall be determined by reference to RECs computed by water usage. The city may change the per month charges and the figures used in computing the RECs by resolution. b. Each nonresidential user shall be charged a minimum of one REC. Any fraction thereof of REC shall be adjusted to the next highest one-half (1/2) REC. C. Payment Of Charges; Late Fee: The sewer rental charge shall be payable to the city. A penalty of ten percent (10%) shall be added to all bills not paid by the date affixed for final payment. (Amended Ord. 32, 11- 25-1975; amd. 2003 Code) 1 See subsection 1-7-3J of this code for specific amounts. D. Assessment Of Unpaid Charges: In the event that a user fails to pay his sewer rental fee within a reasonable time as determined by the city, said fee shall be certified by the City Clerk and assessed against the property connected to the sewer system and forwarded to the County Auditor for collection. (Amended Ord. 32, 11-25-1975) 10-3-4: INDUSTRIAL USER STRENGTH CHARGE: A. Purpose And Authority: The Metropolitan Waste Control Commission, a metropolitan commission organized and existing under the laws of the state (the "Commission"), in order to receive and retain grants in compliance with the Federal Water Pollution Control Act amendments of 1972 and regulations thereunder (the "act"), has determined to impose an industrial user sewer strength charge upon users in the metropolitan disposal system (as defined in Minnesota Statutes Section 473.121, Subdivision 24) to recover operation and maintenance costs of treatment works attributable to the strength of the discharge of industrial waste, such sewer strength charge being in addition to the charge based upon the volume of discharge. In order for the city to pay such costs based upon the strength of industrial discharge and allocated to it each year by the Commission, it is hereby found, determined and declared to be necessary to establish sewer strength charges and a formula for the computation thereof for all industrial users receiving waste treatment services within or served by the city. Furthermore, Minnesota Statutes Section 444.075, subdivision 3, empowers the city to make such sewer charge against the owner, lessee, occupant, or all of them and certify unpaid charges to the County Auditor as a tax lien against the property served. B. Charge Established: For the purpose of paying the costs allocated to the city each year by the Commission that are based upon the strength of discharge of all industrial users receiving waste treatment services within or served by the city, there is hereby approved, adopted and established, in addition to the sewer charge based upon the volume of discharge, a sewer charge upon each person, firm, or corporation receiving waste treatment services within or served by the city, based upon strength of industrial waste discharged into the sewer system in the city (the "strength charge"). (Ord. 224, 7-1-1997) C. Formula For Determining Charge: For the purpose of computation of the strength charge established in Subsection B of this section, there is hereby established, approved and adopted in compliance with the act, the same strength charge formula designated in Resolution 76-172 and Resolution 76-173 adopted by the Commission, such formula being based upon pollution qualities and difficulty of disposal of the sewage produced through an evaluation of pollution qualities and quantities in excess of an annual average base and the proportionate costs of operation and maintenance of waste treatment services provided by the Commission. (Ord. 224, 7-1-1997; amd. 2003 Code) D. Payment Of Charge; Late Payments: It is hereby approved, adopted and established that the strength charge established in Subsection B of this section shall be paid by each industrial user receiving waste treatment services and subject thereto before the twentieth day succeeding the date of billing thereof to such user by or on behalf of the city, and such payment thereof shall be deemed to be delinquent if not so paid to the billing entity before such date. Furthermore, it is hereby established, approved and adopted that if such payment is not paid before such date, an industrial user shall pay interest compounded monthly at the rate of two-thirds of one percent (2/3%) per month on the unpaid balance due. E. Delinquent Charges A Lien: As provided by Minnesota Statutes Section 444.075, Subdivision 3, it is hereby approved, adopted and established that if payment of the strength charge established in Subsection B of this section is not paid before the sixtieth day next succeeding the date of billing thereof to the industrial user by or on behalf of the city, said delinquent sewer strength charge, plus accrued interest established pursuant to Subsection D of this section, shall be deemed to be a charge against the owner, lessee and occupant of the property served, and the city or its agents shall certify such unpaid delinquent balance to the County Auditor with taxes against the property served for collection as other taxes are collected; provided, however, that such certification shall not preclude the city or its agents from recovery of such delinquent sewer strength charge and interest thereon under any other available remedy.
