§ 24-245. Industrial charges and regulations.

All charges for collecting, receiving, transporting and treating industrial sewage and industrial wastewaters shall be subject to negotiation. The amount charged will include all expenses incurred by the board in handling and treating such sewage or waste and shall include any cost of chlorinating the same when mixed with the sewage. All of such service must be approved and the terms and conditions fixed under the provisions of a written contract.

All industrial sewage or industrial wastewaters discharged into the system under agreement with the board where the BOD does not exceed 300 milligrams per liter (mg/l), where the fats do not exceed 100 mg/l and where the suspended solids do not exceed 200 mg/l shall be handled by the board on the aforementioned sewer rates.

Additional charges listed below shall be made when the BOD, the fats and the suspended solids exceed these amounts.

For all sewage having a BOD in excess of 300 mg/l and up to and including 1,000 mg/l, there shall be an additional charge as specified in Appendix A for such excess. Where the BOD is in excess of 1,000 mg/l, there shall be a charge as specified in Appendix A for such additional excess.

For all sewage containing fats in excess of 100 mg/l and up to and including 200 mg/l, there shall be an additional charge as specified in Appendix A for such excess and for sewage containing fats in excess of 200 mg/l, there shall be a charge as specified in Appendix A for such additional excess.

For all sewage containing suspended solids in excess of 200 mg/l, including those suspended solids outlined in section 24-235 above and up to and including 800 mg/l there shall be a charge as specified in Appendix A for such excess and for all sewage containing in excess of 800 mg/l the charge shall be as specified in Appendix A for such additional excess.

For all sewage with a temperature in excess of 100 degrees F shall be charged $0.10 for a degree hour per 1,000 gallons based on average temperature and water used per week.

All industrial or commercial sewage before being discharged into the sewer system of the board shall be metered and no sewage shall be discharged until so metered. All cost of the meter shall be borne by the applicant. Appropriate devices or access areas shall be installed and maintained for the purpose of sampling such sewage and the board shall have the free and continued access over the property of the user for the purpose of sampling the sewage to determine the amount of BOD, fats and suspended solids, to determine the pH, and to determine the temperature of the sewage so as to fix the amount of additional charges which are to be made as provided herein.

The board may take such samples at any time or any place as determined by the board.

In the event excess BOD or fats continue to be discharged after warning from the board, the board may elect to discontinue the service on 24 hours' notice and such election shall not prejudice the claim of the board for any sums due hereunder. Notice of such election shall be given by certified mail.

Any industry that wishes to discharge sewage containing any one or combinations of sewage as outlined in section 24-235 above shall negotiate the charges with the board on all other types of sewage not specifically charged by this article, and cannot discharge any sewage into the system unless and until a written agreement is negotiated and entered into.

The board reserves the right to enter into special contracts with industrial customers for the collection, treatment and disposal of industrial sewage or waste and to enter into contracts for the construction and use of special wastewater treatment plants under the terms and conditions for the use thereof, and the provisions of this section may be altered, changed, amended or extended under the terms and conditions of such contracts.

No statement contained in this section shall be construed as preventing any special contract, agreement, or arrangement between the board and any industrial or commercial concern whereby an industrial sewage of unusual strength or character may be accepted by the board for treatment. However, there shall be no agreements made that would violate any state or federal pretreatment standard.

All measurements, tests, and analysis of the characteristics of waters and sewage to which reference is made in this article shall be determined in accordance with the latest edition of "Standard Methods for the Examination of Water and Wastewater," published by the American Public Health Association. Sampling methods, location, times, durations, and frequencies are to be determined on an individual basis subject to approval by the board.
