The cost of installation of extensions to sanitary sewer mains of the city shall be paid from the general fund of the city, or, at the discretion of the City Council, some portion or all of the cost of any extensions may be assessed to the parcel or parcels specially benefitted by the installation of the extensions, all in accordance with the terms and provisions of M.S. Chapter 429, as it may be amended from time to time, and amendments thereto. However, no extensions shall be permitted unless sufficient capacity exists downstream to handle the expected increased flows from any extensions.
(Ord. 170, passed 8-10-1981)
(A) Sewer service and user charges are imposed upon each lot, parcel of land, building, or premises served by the public sewer and wastewater facilities, or otherwise discharging sewage, including industrial wastes, into the public sewer and wastewater facilities. The user charge shall be included in the sewer service charge, and be payable as hereinafter provided. The methodology of determining the user charge rates is given in the user charge system. The rate schedule will be reviewed annually and adjusted as necessary to maintain a proportional distribution of costs among the users.
(B) The sewer service charge for any lot, parcel of land, building, or premises within the corporate limits, and for any lot, parcel of land, building, or premises outside the corporate limits which is connected to the public sewer system, shall be based upon the quantity of wastewater generated as measured by the water meter or sewage meter in use as follows.
(1) CATEGORY A is defined as normal or domestic strength wastewater having organic concentrations of biochemical oxygen demand (BOD) no greater than 200 milligrams per liter (mg/l) and suspended solids no greater than 250 milligrams per liter (mg/l). The sewer service charge for Category A wastewater is as follows.
Minimum Sewer Service Charge Per Billing Period With One Customer on Each Meter
Meter Size Debt Portion
Meter Size Debt Portion
5/8 inch $3.15 per month
1-inch $7.90 per month
1¼-inch $12.60 per month
1½-inch $18.90 per month
2-inch $31.50 per month
3-inch $50.40 per month
5-inch $201.60 per month
Volumetric user charge $1.15 per 1000 gallons
(2) CATEGORY B is defined as wastewater having organic concentrations of biochemical oxygen demand (BOD) greater than 200 milligrams per liter (mg/l) and/or suspended solids greater than 250 milligrams per liter (mg/l). The minimum Category B charge for BOD and suspended solids will be based on a concentration of 200 mg/l for BOD and 250 mg/l for suspended solids. The sewer charge for Category B wastewater is as follows.
SSC = Category A charge (service charge + volumetric charge)
+ (BOD - 200) x V x .00834 x CB
+ (SS - 250) x V x .00834 x CS
in which: SSC = Total Sewer Service Charge per quarter
BOD = Biochemical Oxygen Demand expressed as mg/1
SS = Suspended solids expressed as mg/1
CB = BOD unit price $.18/1000 pounds
CS = SS unit price $.35/1000 pounds
V = Total volume of water used, thousand gallons
(3) When the user places wastewater in a holding tank so that the flow is distributed over a 20 to 24-hour period, no further adjustment in the user charge shall be made. When no holding tank is provided and used by the user, the sewer service charge aforesaid will be further adjusted by the hours of operation per day divided by hours discharged, to be averaged over the entire quarter (such as a user with an average operation of 12 hours per day would have the sewer service charge increased by 24/12 to arrive at the final user charge).
(C) Reassignment of sewer users. The approving authority will reassign users into appropriate sewer service charge categories if wastewater sampling programs and other related information indicate a change of categories is necessary.
(D) Additional charges. Additional charges shall be imposed upon each lot, parcel of land, building or premises served by public sewer and wastewater facilities located outside the boundaries of the approving authority, to equalize local capital costs. The additional charge shall result in a minimum charge equal to the debt charge for each user, according to the schedule for debt repayment from utility revenues. Additional charges shall be added to the sewer bill for each billing period.

(A) Definitions. For the purpose of this section, the following definitions shall apply, unless the context clearly indicates or requires a different meaning.
(1) COST OF RECOVERY CHARGE. A charge collected from users discharging industrial wastes for the recovery of the Federal EPA grant amount allocable to the treatment of wastes, and is proportionate to the volume and pollutional characteristics at design capacity of Federal EPA-funded wastewater collection and treatment facilities.
(2) INDUSTRIAL USER. Any non-governmental, nonresidential user of a publicly-owned treatment works which discharges more than the equivalent of 25,000 gallons per day (gpd) of sanitary wastes and which is identified in the Standard Industrial supplement under one of the following divisions.
Division A--Agriculture, Forestry and Fishing.
Division B--Mining.
Division D--Manufacturing.
Division E--Transportation, Communications, Electric, Gas, and Sanitary Services.
(a) In determining the amount of a user’s discharge for purposes of industrial cost recovery, the grantee may exclude domestic wastes or discharges from sanitary conveniences.
(b) After applying the sanitary waste exclusion in division (A)(2)(a) of this section (if the grantee chooses to do so), dischargers in the above divisions that have a volume exceeding 25,000 gpd, or the weight of biochemical oxygen demand (BOD) or suspended solids (SS) equivalent to that weight found in 25,000 gpd of sanitary waste, are considered industrial users. Sanitary wastes, for purposes of this calculation of equivalency, are the wastes discharges from residential users having a strength of 200 mg/l BOD and 250 mg/l SS. Any non-governmental user of a publicly-owned treatment works discharging wastewater to the treatment works which contains toxic pollutants or poisonous solids, liquids, or gases in sufficient quantity, either singly or by interaction with other wastes, to contaminate the sludge of any municipal systems, or to injure or to interfere with any sewage treatment process, or which constitutes a hazard to humans or animals, creates a public nuisance, or creates any hazard in or has an adverse effect on the waters receiving any discharge from the treatment works, shall be in violation of this ordinance.
(B) Cost recovery charge. In addition to the sewer service charge imposed on each user herein, cost recovery charge shall be imposed upon each industrial user. The charge shall be payable on the quarterly basis, and shall be the greater of the actual usage of projected reserve capacity of the industrial user. For purposes of cost recovery charge, the approving authority may exclude domestic waste in determining the amount of usage. The cost recovery charge shall be payable as hereinafter provided, and in an amount determinable as follows. The cost recovery charge of any industrial user shall be based upon the quantity of water used and quality of wastewater generated as measured by the water meter or sewage meter in use as follows.
Volume Charge (RV) - $1.55 per 1,000 gallons per day per year
BOD Charge (RB) - $.20 per pounds BOD per day per year
Suspended Solids Charge (RS) $.20 per pounds SS per day per year
R = (V x RV) + (V x RB x B x .00834) + (V x RS x S x .00834)
in which: R = cost recovery charge
V = wastewater volume in 1000 gallons of flow
B = concentration of BOD in milligrams per liter (mg/l) in wastewater
S = concentration of suspended solids in milligrams per liter (mg/l) in wastewater
(C) Recovery and disbursement of revenues. The recovery and the disbursement of revenues collected by the city through the cost recovery charge shall conform to the 40 CFR 35.928-1 and 35.928-2, promulgated by the Federal Water Pollution Control Act Amendment of 1972.
(Ord. 170, passed 8-10-1981) Penalty, see § 10.99
(A) Payment and penalty. The sewer service charge shall be for the corresponding period of the water bills, and shall be payable to the City Administrator/Clerk-Treasurer and Utility Secretary Cashier not later than two months after the end of each period. A penalty of 5% shall be added to all bills not paid by the date fixed for final payment.
(B) Lien. All sewage charges shall be a lien upon the property served pursuant to the applicable Minnesota Statutes, and shall be collected in the manner therein provided.
(C) Disposition of revenue. The amounts received from the collection of charges authorized by this chapter shall be credited to a sanitary sewerage account, which shall show all receipts and expenditures of the sewerage system. When appropriated by the Council, the credits to the account shall be available for the payment of the requirements for operation, maintenance, repairs, and depreciation of the
sewerage system consistent with 40 CFR 35.929. Any surplus in the account shall be available for the payment of principal and interest of bonds issued and outstanding, or which may be issued, to provide funds for the sewerage system, or part thereof, and all or a part of the expenses for additions and improvements and other necessary disbursements or indebtedness, and the Council may, by resolution, pledge the surplus or any part thereof for any purpose. All present outstanding sewer system general obligation bonds, including the refunding bonds, shall be paid from this fund, both principal and interest.
(Ord. 170, passed 8-10-1981) Penalty, see § 10.99
The city shall conduct an annual audit, fulfilling the requirements of 40 CFR 35.929(b), the purpose of which shall be to maintain the proportionality between users and user classes of the user charge system, and to ensure the adequate revenues are available relative to increasing operation, maintenance, and replacement costs.
