(A) No person shall discharge or cause to be discharged any storm water, surface water, ground water, roof runoff, subsurface drainage, uncontaminated cooling water, or unpolluted industrial process waters to any sanitary sewer. Storm water and all other unpolluted drainage shall be discharged as provided for in Chapter 53.
(B) No person shall discharge or cause to be discharged any of the following described waters or wastes to any city sewers.
(1) Any gasoline, benzene, naphtha, fuel oil, or other flammable or explosive liquid, solid, or gas.
(2) Any waters or wastes containing toxic or poisonous solids, liquids, or gases in sufficient quantity, either singly or by interaction with other wastes, to injure or interfere with any wastewater treatment process, constitute a hazard to humans or animals, create a public nuisance, or create any hazard in the receiving waters of the wastewater treatment plant, including but not limited to cyanides in excess of 2 mg/l as CN (cyanide) in the wastes as discharged to the city sewer.
(3) Any waters or wastes having a pH lower than 5.5, or having any other corrosive property capable of causing damage or hazard to structures, equipment, or personnel of the wastewater works.
(4) Solid or viscous substances in quantities or of a size capable of causing obstruction to the flow in sewers or other interference with the proper operation of the wastewater system such as, but not limited to, ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar, plastics, wood, unground garbage, whole blood, paunch manure, hair and fleshings, entrails, and paper dishes, cups, milk containers, and the like, either whole or ground by garbage grinders.
(C) No person shall discharge or cause to be discharged the following described substances, materials, waters, or wastes if it appears likely in the opinion of the Director that the wastes can harm either the wastewater system, wastewater treatment process, or equipment, have an adverse effect on the receiving stream, or can otherwise endanger life, limb, public property, or constitute a nuisance. In forming his opinion as to the acceptability of these wastes, the Director will give consideration to such factors as the quantities of subject wastes in relation to flows and velocities in the wastewater system, materials of construction of the wastewater system, nature of the wastewater treatment process, capacity of the wastewater treatment plant, degree of treatability of wastes in the wastewater treatment plant, and other pertinent factors. Combined sewage systems are prohibited in the city. The substances prohibited are as follows.
(1) Any liquid or vapor having a temperature higher than 150°F. or 65°C.
(2) Any water or waste containing fats, wax, grease, or oil, whether emulsified or not, in excess of, 100 mg/l or containing substances which may solidify or become viscous at temperatures between 32°F. and 150°F. (0°C. and 65°C.)
(3) Any garbage that has not been properly shredded.
(4) Any waters or wastes containing strong acid iron pickling wastes or concentrated plating solutions whether neutralized or not.
(5) Any water or wastes containing iron, chromium, copper, zinc, and similar objectionable or toxic substances, or wastes exerting an excessive chlorine requirement, to a degree that any such material received in the composite wastewater at the wastewater treatment works exceeds the limits established by the Director for these materials.
(6) Any waters or wastes containing phenols or other taste- or odor-producing substances, in such concentrations exceeding limits established by the Director as necessary, after treatment of the composite wastewater, to meet the requirements of the state, federal, or other public agencies of jurisdiction for discharge to the receiving waters.
(7) Any radioactive wastes or isotopes of half-life or concentration as may exceed limits established by the Director in compliance with applicable state or federal regulations.
(8) Any waters or wastes having a pH in excess of 9.5.
(9) Materials which exert or cause the following:
(a) Unusual concentrations of inert suspended solids (such as, but not limited to, Fullers earth, lime slurries, and lime residues) or of dissolved solids (such as, but not limited to, sodium chloride and sodium sulfate).
(b) Excessive discoloration (such as, but not limited to, dye wastes and vegetable tanning solutions).
(c) Unusual BOD, chemical oxygen demand, or chlorine requirements in such quantities as to constitute a significant load on the wastewater treatment works.
(d) Unusual volume of flow or concentration of wastes constituting slugs as defined in § 51.01.
(10) Waters or wastes containing substances which are not amenable to treatment or reduction by the wastewater treatment processes employed, or are amenable to treatment only to the degree that the wastewater treatment plant effluent cannot meet the requirements of other agencies having jurisdiction over discharge to the receiving waters.
(11) All flows shall comply with Broward County ordinances and city pre-treatment policies.
(D) If any waters or wastes are discharged, or are proposed to be discharged to the city wastewater system, which contain the substances or possess the characteristics enumerated in subsection(C) of this section, and which in the judgment of the Director, may have a deleterious effect upon the wastewater system, processes, equipment, or receiving waters, or which otherwise create a hazard to life or constitute a public nuisance, the Director may do the following.
(1) Reject the wastes.
(2) Require pretreatment to an acceptable condition for discharge to the city wastewater system.
(3) Require control over the quantities and rates of discharge.
(4) Require payment to cover the added cost of handling and treating the wastes not covered by existing wastewater charges.
(5) If the Director permits the pretreatment or equalization of waste flows, the design and installation of the plants and equipment shall be subject to the review and approval of the Director, and subject to the requirements of all applicable codes, ordinances, and laws.
(E) Grease, oil, and sand interceptors shall be provided when, in the opinion of the Director, they are necessary for the proper handling of liquid wastes containing grease in excessive amounts, or any flammable wastes, sand, or other harmful ingredients, however, these interceptors shall not be required for private living quarters or dwelling units. All interceptors shall be of a type and capacity approved by the Director, and be located as to be readily and easily accessible for cleaning and inspection.
(F) Where preliminary treatment or flow-equalizing facilities are provided for any waters or wastes, they shall be maintained continuously in satisfactory and effective operation by the owner at his expense.
(G) When required by the Director, the owner of any property serviced by a building wastewater system carrying industrial wastes shall install a suitable control manhole together with the necessary meters and other appurtenances in the building wastewater system to facilitate observation, sampling, and measurement of the wastes. The manhole, when required, shall be accessibly and safely located, and shall be constructed in accordance with plans submitted to the City Engineer for review and approved by the Director. The manhole shall be installed by the owner at his expense, and shall be maintained by him so as to be safe and accessible at all times.
(H) All measurements, tests, and analyses of the characteristics of waters and wastes to which reference is made in this chapter shall be determined in accordance with the latest edition of “Standard Methods for the Examination of Water and Wastewater,” published by the American Public Health Association, and shall be determined at the control manhole provided, or upon suitable samples taken at the control manhole. In the event no special manhole has been required, the control manhole shall be considered to be the nearest downstream manhole in the city wastewater system to the point at which the building wastewater system is connected. Sampling shall be carried out by customarily accepted methods to reflect the effect of constituents upon the wastewater works and to determine the existence of hazards to life, limb, and property. The particular analyses involved will determine whether a 24-hour composite of all outfalls of a premise is appropriate or whether a grab sample or samples should be taken. Normally, but not always, BOD and suspended solid analyses are obtained from 24-hour composites of all outfalls whereas pH’s are determined from periodic grab samples.
(I) No statement contained in this chapter shall be construed as preventing any special agreement or arrangement between the city and any industrial concern whereby an industrial waste of unusual strength or character may be accepted by the city for treatment, subject to payment by the industrial concern.
