(A) Sewer service charge unit costs. For purposes of determining proportionate user charges, determine the annual OM&R budget. Calculation of unit costs for treatment of flow, BOD, suspended solids (TSS) and nitrogen (TKN) shall be determined and fixed annually in the sewer service charge system according to the procedures contained in Appendix E of the March 1988 report entitled, “Sewer Service Charge System for Wastewater Treatment Facilities” for the city.
(B) Category A sewer service charge. Calculation of Category A sewer service charges shall be determined and fixed annually in the sewer service charge system according to the procedures contained in Appendix E of the above referenced March 1988 rate study report.
(C) Category B sewer service charge.
(1) The Category B sewer service charge shall be computed in accordance with the formula presented below:
T = FQ + (V x CV) + .00834 V (B x CB + S x CS + N x CN)
where: T = total sewer service charge; FQ = fixed quarterly charge; B = concentration of BOD in mg/l in the wastewater above 200 mg/l; S = concentration of suspended solids in mg/l in the wastewater above 300 mg/l; N = concentration of nitrogen in mg/l in the wastewater above 45 mg/l; V = wastewater volume in 1,000 gallons; CV = Category A volume charge cost per 1,000 gallons; CB = cost per pound of BOD; CS = cost per pound of suspended solids; CN = cost per pound of nitrogen; and 0.00834 = conversion factor.
(2) The above formula shall not be construed to give credits for a waste strength less than domestic concentrations for BOD, suspended solids or nitrogen.
(3) The charge for BOD in mg/l in the wastewater above 200 mg/l, based on the total pounds of BOD, shall be $0.32 per pound.
(D) Reassignment of sewer users. The Council will reassign sewer users into appropriate sewer service charge categories if wastewater sampling programs or other related information indicate a change of categories is necessary.
(2004 Code, § 53.103) (Ord. 781, passed 7-19-1988; Ord. 05-400, passed 4-12-2005)
All sewer service charge revenues collected for replacement costs shall be deposited in a separate and distinct fund to be used solely for replacement costs as defined in § 53.001 of this chapter. All sewer service charge revenues collected for other operation and maintenance expenses shall also be deposited in a separate and distinct fund. All revenues for the replacement fund and for operation and maintenance of the wastewater treatment facilities shall be used solely for the replacement fund and operation and maintenance of the wastewater treatment facilities.
(2004 Code, § 53.104) (Ord. 781, passed 7-19-1988)
(A) No person in the business of gathering and disposing of septic tank sludge or holding tank sewage shall transfer this material into any disposal area or public sewer unless a permit for disposal has been first obtained from the Council. Written application for this permit shall be made to the Council and shall state the name and address of the applicant, the number of its disposal units and the make, model and license number of each unit. Permits shall be non-transferable except in the case of replacement of the disposal unit for which a permit shall have been originally issued. The permit may be obtained upon payment of the annual permit fee. The time and place of disposal will be designated by the Council. The Council may impose conditions as it deems necessary on any permit granted.
(B) (1) Any person or party disposing of septic tank sludge or holding tank sewage agrees to carry public liability insurance in an amount not less than $100,000 to protect any and all persons or property from injury or damage caused in any way or manner by an act, or the failure to act, by any of the person’s employees. The person shall furnish a certificate certifying this insurance to be in full force and effect.
(2) All materials in the septic tank sludge or holding tank sewage disposed of into the treatment system shall be of domestic origin, or compatible pollutants only, and the person agrees that he or she will comply with the provisions of any and all applicable city code provisions and shall not deposit or drain any gasoline, oil, acid, alkali, grease, rags, waste, volatile or flammable liquids or other deleterious substances into the public sewers, nor allow any earth, sand or other solid material to pass into any part of the wastewater treatment facilities.
(3) Persons with a permit for disposing of septic tank sludge or holding tank sewage into the wastewater treatment facilities shall be charged the sewer service charges for these users as calculated annually in accordance with the procedures contained in Appendix E of the March 1988 report entitled, “Sewer Service Charge System for Wastewater Treatment Facilities” for the city.
(4) The person disposing of septic tank sludge or holding tank sewage agrees to indemnify and hold harmless the city from any and all liability and claims for damages arising out of or resulting from work and labor performed.
