(A) The city hereby establishes a sewer service charge system whereby all revenue collected from users of the wastewater treatment facilities will be used to affect all expenditures incurred for annual operation, maintenance and replacement and for debt service on capital expenditure incurred in constructing the wastewater treatment works.
(B) Each user shall pay its proportionate share of operation maintenance and replacement costs of the treatment works, based on the users proportionate contribution to the total wastewater loading from all users.
(C) Each user shall pay debt service charges to retire local capital costs as determined by the City Council.
(D) Sewer service rates and charges to users of the wastewater treatment facility shall be determined and fixed in a “sewer service charge system” developed, and approved by the city’s Public Utilities Commission.
(E) Revenues collected for sewer service shall be deposited in a separate fund known as the “Sewer Service Fund”. Income from revenues collected will be expended to offset the cost of operation, maintenance and equipment replacement for the facility and to retire the debt for capital expenditures.
(F) The sewer service charges established shall not prevent the assessment of additional charges to users who discharge wastes with concentrations greater than normal domestic strength or wastes of unusual character or contractual agreements with the users.
(G) Delinquent accounts shall be certified to the City Administrator, who shall prepare an assessment roll each year providing for assessment of the delinquent amounts against the respective properties served. The assessment roll shall be delivered to the Council for adoption on or before September 1 of each year. Upon the adoption, the Administrator shall certify the assessment roll to the County Auditor for collection along with taxes. Assessments shall bear interest at a rate of 8% per annum.
