The written permission to construct 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, garage floor drains, bars, soda fountains, cuspidors, refrigerator drips, drinking fountains, stable floor drains and other objectionable wastes shall be discharged into only a sanitary or combined sewer 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 treatment works. Where such waste is detrimental to the sewer system or sewage treatment 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 treatment works.
(c) Surface water, rain water from roofs, subsoil drainage, building foundation drainage, cistern overflow, clean water from condensers, waste water from water motors and elevators, and any other clean and unobjectionable waste water shall be discharged into a storm water or combined sewer and in no case into a sanitary sewer.
(d) Connection with a cesspool or privy vault shall not be made into a sanitary, combined or storm water sewer.
(e) A trap for the interception of grease and oil shall be provided on a connection from a hotel, factory, grain mill, and/or elevator, restaurant, club or institutional kitchen and from a public garage or automobile washing station. Such trap shall be satisfactory to the Safety-Service 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.
(h) Some means of measuring 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 are deemed necessary by the Director. Failure to provide such means when required shall be deemed a violation of this chapter.
(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 by such person, firm or corporation and from such premises. After such permission has been granted, no one shall fail or refuse to allow such entrance and collection of samples by the City representative.
