(b) Industrial Cost Recovery 1. Each non-governmental industrial user shall pay that portion of any state grant which has been obtained by the Village of Colfax for the financing of the construction of wastéwater treatment works allocable to the treatment of the wastewater from such user. Such user's share shall not include an interest component.
2. An industrial user's portion of any state grant shall be based on the sum of the costs of each factor which significantly influences the cost of the treatment works attributable to the wastewater discharge of such user tributary to the wastewater treatment works of the Village of Colfax. Those significant factors shall be as follows:
A. Volume of waste discharged: This factor is equivalent to the water consumption by the user or, where water consumption does not reflect the actual quantity of wastewater tributary to the treatment works from such user, then the volume of flow as recorded in the control manhole required by Section 7. 06 (h) and Section 7. 09 (b) 19 shall be used.
B. Five-Day Biochemical Oxygen Demand (BOD): This factor, as defined in Section 7. 09 (a) shall be used to determine the strength of the waste discharged by such user. The numerical values of the BOD factor shall be obtained from samples collected from a control manhole as required by Section 7. 06 (h) and Section 7. 09 (b) 19. The SOD factor shall be con verted from the average milligrams per liter of SOD discharged to the ave rage pounds of DOD discharged. (Pounds of SOD equals milligrams per liter DOD times 8. 34 times the volume of waste discharged per billing period divided by 1, 000, 000.)
C. Suspended Solids: This factor, as defined in Section 7. 09 (a) shall be used to determine the strength of the waste discharged by such user. The numerical value of the suspended solid factor shall be obtained from. samples collected from a control manhole as required by Section 7. 06 (h) and Section 7. 09 (b). The suspended solids factor shall be converted from the average milligrams per liter of suspended solids discharged. (Pounds of suspended solids equals milligrams per liter of suspended solids times 8. 34 times the volume of waste discharged per billing period divided by
1, 000, 000.
3. The unit cost per wastewater characteristic factor shall be as follows:
A. 27. 2 cents per 1, 000 gallons of waste discharged;
B. 12. 5 cents per pound of SOD discharged;
C. 7. 3 cents per pound of suspended solids discharged.
4. The industrial cost recovery charge to be recovered from an industrial user shall be collected as described in Section 7. 09 (b) 5. The charge shall be the sum of the charges for volume, SOD and suspended solids, each of which shall be determined as follows:
A. Where the industrial waste discharge quantities are measured separately from the domestic discharge of such user, the in dustrial cost recovery amount shall be computed directly using unit costs in Section 7. 09 (b} 3.
B. Where the industrial waste discharge quantities are not separately measured from the domestic discharge of such user, the in dustrial cost recovery amount shall be determined as follows:
(1) Charge for volume discharge: Equals volume of dis charge as determined in Section 7. 09 (b) ZA minus an allowance for the normal domestic portion determined in accordance with Section 7. 09 (b) 20 times 27. 2 cents per 1, 000 gallons.
(2) Charge for SOD discharge: Equals 12. 5 cents times the average pounds of SOD discharge per billing period as defined in Section 7. 09 (b) 25 minus an allowance for the normal domestic portion determined in accordance with Section 7. 09 (b) 20 5.
(3) Charge for suspended solids discharge: Equals 7. 3 cents times the average pounds of suspended solids discharged per billing period as defined in Section 7. 09 (b) 2C minus an allowance for the normal domestic portion determined in accordance with Section 7. 09 (b) 20.
Any value calculated in Section 7. 09 (b) 4 that is equal to or less than zero shall not result in a monetary charge for that waste characteristic factor.
5. Each month during the industrial cost recovery period, each industrial user of the treatment works shall pay the cost recovery amount determined by Section 7. 09 (b) 4 for such industry. Where an industry is connected to a public sewer after the start-up of the facilities constructed under a federal grant, such industry shall only pay its portion of the federal grant for each month remaining in the recovery period. Such industry will not be required to pay for those months of the recovery period prior to con nection to a public sewer.
6. The industrial cost recc period shall be equal to the useful life of the treatment works which shall be 30 years from July 1978.
7. For the purpose of industrial cost recovery, the calendar year shall be divided into monthly periods, said periods to begin on the first day of the month and all industrial users of the Village of Colfax.shall pay the cost as determined by Section 7.09 (b) 4 for industrial cost recovery and such payments shall be made monthly and such charge shall be payable within 15 days after rendition thereof, and in the event such bills are not paid within said 15 days, a service charge of 5 percent shall be added thereto.
8. In the event the charges for industrial cost recovery are not paid within 30 days after rendition of that bill, then such service charges shall be deemed and are hereby declared to be delinquent, and thereafter such delinquent charge shall constitute a lien upon the real estate for which such sewer services were supplied.
The Village Clerk is hereby authorized and directed each month to file sworn statements showing such delinquencies in the office of the Recàrder of Deeds of McLean County, Illinois, and the filing of such statements shall be deemed notice of a lien for the payment of such charges for sewer service. If the delinquency in the payment of the recovery cost continues for a period of more than 30 days, the sewer and/or water service shall be discontinued.
9. The initial payment made by an industrial user which is con nected to a public
- sewer after the start-up of the treatment works constructed with a state grant shall be made by the next scheduled due date as defined in Section 7. 09 (b) 7.
