All industrial users shall be charged a sewer rate based on their water meter size unless, however, the industrial user has installed a sewer flow meter, in which case all industrial user charges shall be established by separate agreement between each separate contributing industry and the mayor and council. All charges so established shall be in proportion to the benefits derived by the user from the sewerage system. The charges so established shall generate sufficient revenue to pay the operation and maintenance of the sewerage system, and the industrial cost recovery charges. Special allowances may be made on a case by case basis for temporary industrial connections. The charges shall be based on the amount of flow (Q), the biochemical oxygen demand (BOD), the suspended solids (SS) and any other pertinent components of the wastes that the industrial user is contributing to the sewerage system or that may affect the wastewater treatment system. (Ord. 463, 5-30-2000)
A. Annual Review: All contributing industrial user charges shall be reviewed annually and revised as necessary to ensure that each contributing industrial user pays its allocable share. If the discharge of a contributing industrial user changes significantly, greater than ten percent (10%) plus or minus (by strength, volume, delivery flow rate or other pertinent component characteristics), such industrial user's charge shall be adjusted accordingly to assure that the user continues to pay its allocable share.
B. Pretreated Wastes: Contributing industrial users discharging pretreated process wastes into the sewerage system shall pay industrial user charges based on the characteristics of the waste effluent from the pretreatment facilities. (Ord. 461, 4-10-2000)
C. Basis For Payment: The amount of payment required from an industry for industrial user charges is to be the sum of the operation and maintenance charges and the industrial cost recovery charges. Special allowances may be made for temporary connections. (Ord. 463, 5-20-2000)
D. Actions For Nonpayment: Actions for nonpayment will be in accordance with section 10-3-37 of this chapter. (Ord. 461, 4-10-2000)
E. Monitoring Equipment: The industry is responsible for providing and installing the monitoring equipment, its operation and maintenance, and all testing and laboratory fees. (Ord. 463, 5-30-2000)
