Although the proposed sewage treatment works will be capable of treating properly shredded garbage, the actual treatment of the garbage will increase the cost of operating and maintaining the sewage treatment plant and the public sanitary sewage system. Therefore, there is hereby imposed upon each person discharging such garbage into the public sanitary system an additional charge which is intended to cover such additional cost. Such surcharge shall be in addition the regular service charge set forth in Article XI of this Part 2 and shall be payable as hereinafter provided in the amount hereinafter provided.
The additional charge for garbage grinders shall be in accordance with the following schedule:
A. 
Household garbage grinders. For each household garbage grinder in a private dwelling unit: $0.40 per month.
B. 
Other-than-household garbage grinders. For garbage grinders other than household grinders referred to in Subsection A of this section: $5 per month per grinder of one-horsepower capacity, and a proportionately lower or higher charge per grinder of lesser or greater horsepower.
The additional charges provided for in this article will be added to the service charges set forth in Article XI. They will be billed monthly and shall be due at the same time and shall be subject to the same penalty as set forth in § 371-63. Notwithstanding the foregoing provisions of this article, no additional charge will begin to occur until after the sewage treatment plant works are put into operation.
