The economy and desirability of the combined treatment of industrial waste and sanitary sewage is recognized. The treatment facilities constructed by the City are of the type and design to permit reasonable flexibility in the treatment of various types of industrial wastes. In general, any and all industrial wastes may be discharged to the public sanitary sewerage system except those which are deemed harmful to the system or are specifically prohibited by this article. However, it is also recognized that the treatment of abnormal industrial wastes may add to the cost of operating and maintaining the public sanitary sewerage system. Such cost should be borne by the persons receiving benefit therefrom.
