The written permission to construct a building sewer, also known as a house sewer, or to make a connection to a public sewer shall specify the permissible use of such house sewer and connection and such specifications shall be governed by the following requirements:
   (a)   Sewage, including wastes from water closets, urinals, lavatories, sinks, bath tubs, showers, laundries, cellar floor drains, bars, soda fountains, cuspidors, refrigerator drips, drinking fountains, stable floor drains and other objectionable wastes shall be discharged into an approved sanitary sewer only and in no case into a storm water sewer.
   (b)   Industrial waste shall not be discharged into a storm water sewer but may be discharged into a sanitary sewer if the waste is of such character as not to be detrimental to the sewer system or to the sewage disposal works. Where such waste is detrimental to the sewer system or sewage disposal works it shall be otherwise disposed of in a satisfactory manner or so improved in character as not to be detrimental to the sewer system or sewage disposal works.
   (c)   Surface water, rain water from roofs, subsoil drainage, building foundation drainage, cistern overflow, clean water from condensers, wastewater from water motors and elevators and any other clean and unobjectionable wastewater shall be discharged into a storm water sewer and in no case into a sanitary sewer.
      (1)   Roofs, paved or surfaced areas, yards, courts, patios and any other surface areas shall be drained into a storm sewer, either by draining directly to a storm sewer or by draining directly or indirectly through a curb to a street which drains to a storm sewer.
      (2)   Where subsoil drains are placed under a cellar floor or basement floor, or are used to encircle either the inner or outer building footers or walls, they shall not be connected to a sanitary sewer but shall be connected to a storm sewer or shall be discharged to a sump and then discharged either to a storm sewer or to a street gutter, or be free-discharged to the existing ground level at a point not less than ten feet from any exterior wall of any building.
      (3)   Storm water or any other clean unobjectionable waste shall not be drained or discharged into any sanitary sewer.
      (4)   In the event it is necessary to utilize a pump or pumps for the discharge of any sanitary waste to a sanitary sewer, any storm water or other unobjectionable wastes to be discharged from any premises shall be handled separately to a storm sewer, to a street gutter or to be free discharge ten feet distant from any building wall.
   (d)   Connection with a cesspool or privy vault shall not be made into a sanitary, combined or storm water sewer.
   (e)   An interceptor for the trapping of grease and oil shall be provided on a connection from a hotel, factory, grain mill and/or elevator, restaurant, club or institutional kitchen, commercial garage or automobile washing station, or other use as determined by the Director. Such trap shall meet the requirements of the Director.
   (f)   A screen or other contrivance for the interception of objectionable solids shall be provided on a connection from a mill, canning factory or any other institution or building in which any business is conducted of such a nature as to create possible objectionable solids entering the sanitary sewer system. Such screen or contrivance shall be subject to the approval of the Director.
   (g)   No person shall discharge into a house sewer or tap a house sewer for the purpose of discharging into it any waste or drainage water prohibited by the provisions of this section. Any existing connection in violation of the provisions of this section shall be abandoned and removed at the owners expense.
   (h)   Some means of measuring the flow of wastes satisfactory to the Director, shall be provided for the premises of any person, firm or corporation from which wastes are emptied into the sanitary sewer, where such wastes cannot be adequately measured without such means and/or where such means is deemed necessary by the Director. The failure to provide such means when required shall be deemed a violation of this section and shall be subject to the penalty in Section 925.99.
   (i)   Permission to tap to the sanitary sewer system of the City shall be granted only subject to the condition that the person, firm or corporation to whom such permission is granted shall allow a representative of the City to enter upon the premises of such person, firm or corporation tapped to such sewer, at any and all reasonable times to collect representative samples of wastes being emptied into the sewer system. After such permission has been granted, failure or refusal to allow such entrance and collection of samples by such City representative shall be deemed a violation of this section and shall be subject to the penalty in Section 925.99.
