§ 52.10  USE OF PUBLIC SEWERS.
   (A)   Discharge of unpolluted drainage into sanitary sewer; prohibited.  No person shall discharge or cause to be discharged any storm water, surface water, ground water, roof run-off, foundation drainage, cooling water or unpolluted industrial process waters to any sanitary sewer.
   (B)   Discharge of harmful waters or wastes; prohibited.  No person shall discharge or cause to be discharged to any public sewer any harmful waters or wastes, whether liquid, solid or gas, capable of causing obstruction to the flow in sewers, damage or hazard to structures, equipment and personnel of the sewage works or other interference with the proper operation of the sewage works.
   (C)   Interceptors.  Grease, oil and sand interceptors shall be provided when, in the opinion of the Inspector, they are necessary for the proper handling of liquid wastes containing grease in excessive amounts, or any flammable wastes, sand and other harmful ingredients except that the interceptors shall not be required for private living quarters or dwelling units. Where installed, they shall be maintained by the owner, at his or her expense, in continuously efficient operation at all times.
   (D)   Preliminary treatment facilities.  The admission into the public sanitary sewers of any waters or wastes having harmful or objectionable characteristics shall be subject to the review and approval of the operator who may prescribe limits on the strength and character of these waters or wastes. Where necessary, in the opinion of the operator, the owner shall provide, at his or her expense, the preliminary treatment as may be necessary to treat these wastes prior to discharge to the public sanitary sewer. Plans, specifications and any other pertinent information relating to proposed preliminary treatment facilities shall be submitted for the approval of the operator and if required to the Michigan State Board of Public Health and/or the Michigan Department of Environmental Quality, and no construction of the facilities shall be commenced until the approval is obtained in writing. Where preliminary treatment facilities are provided for any waters or wastes, they shall be maintained continuously in satisfactory and effective operation by the owner at his or her expense.
   (E)   Sampling; water analysis.  When required by the operator, the owner of any property served by a building sanitary sewer carrying industrial wastes shall install and maintain at his or her expense a suitable control manhole in the building sanitary sewer to facilitate observation, sampling and measurement of the wastes. All measurements, tests and analyses of the characteristics of water and wastes shall be determined in accordance with Standard Methods for the Examination of Water and Sewage, and shall be determined at the control manhole or upon suitable samples taken at the control manhole. In the event that no special manhole has been required, the control manhole shall be considered to be the nearest downstream manhole in the public sanitary sewer to the point at which the building sanitary sewer is connected.
