C. Any gasoline, benzine, naphtha, fuel oil or other flammable or explosive liquid, solid or gas;
D. Any garbage that has not been shredded to such a degree that all particles will be carried freely under the flow conditions normally prevailing in public sewers, with no particle greater than one-half inch in any dimension;
E. Any ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar, plastics, wood, paunch manure, or any other solid or viscous substance capable of causing obstruction to the flow in sewers or other interference with the proper operation of the sewage works;

If the water is discharged by pumping, the rate of flow shall not exceed one hundred gallons per minute. Under no circumstances however shall the discharge into the public sewer exceed more than one-third the capacity of the main sewer in the street to which the lateral sewer is connected. Each swimming pool discharging to a sanitary sewer shall be equipped with an approved separator to preclude any possibility of a backflow of sewage into the swimming pool or piping system. (Ord. 2-62 §317, 1962).
