939.06 INDUSTRIAL WASTES.
   (a)    The City will receive and treat any and all industrial wastes. However, the City reserves the right to refuse to receive and treat industrial wastes that are destructive to sewerage works or seriously disturb or interfere with the established sewage treatment processes.
   (b)    Periodic sampling and analysis of the wastes of any industries concerned may be made by the City. The frequency of sampling and analysis shall be as determined by the City. If upon these examinations, wastes are determined to be destructive or disturbing to the sewage treatment processes, or would materially increase the cost of sewage treatment operations, the handling of wastes shall be subject to the following. In the event that industrial wastes are destructive to sewerage works or seriously disturb or interfere with the established treatment processes, the City may, upon fifteen days' written notice, refuse to accept sewage from the industry or any other person concerned; or the City may require the industry or any other person concerned to install facilities for the control or modification of the wastes to the satisfaction of the Superintendent before the wastes are discharged into the City's sewage system. Plans for pretreatment and control works must be submitted to and approved by the Superintendent and the State Department of Health.
   (c)    Whenever the hydrogen ion concentration of industrial wastes as measured by the pH value is less than 6.0 or greater than 9.0 during the quarter year for which the bill is to be rendered, the rate of sewer service charge shall be as set forth in Section 939.04. This special charge may apply to all or a part of the wastes from any particular industry, person, or other user of the City sewerage system.
