(h) Whenever possible, the building sewer shall be brought to the building at an elevation below the basement floor. In all buildings in which any building drain is too low to permit gravity flow to the sewer system, sewage carried by such building drain shall be lifted by an approved means and discharged to the building sewer.

(i) No person(s) shall make connection of roof downspouts, foundation drains, areaway drains, or other sources of surface runoff or groundwater to a building sewer or building drain which in turn is connected directly or indirectly to a sanitary sewer unless such connection is approved by the Board for purposes of disposal of polluted surface drainage.

6-7-5 Use of Sanitary Sewers

(a) No person(s) shall discharge or cause to be discharged any unpolluted waters such as stormwater, groundwater, roof runoff, subsurface drainage, or cooling water to the sewer system.

(b) Stormwater and all other unpolluted drainage shall be discharged to such sewers as are specifically designated as storm drains or to a natural outlet. Unpolluted industrial cooling water of process waters shall be discharged to a storm drain or natural outlet.

(c) No person(s) shall discharge or cause to be discharged any of the following described waters or wastes to the sewer system:

1. Any gasoline, benzene, naphtha, fuel oil, lubricating oil, or other flammable or explosive liquid, solid, or gas.
2. Any waters 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 waste treatment process, constitute a hazard to humans or animals, or create a public nuisance.
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, and personnel.
4. Solid or viscous substances in quantities or of such size capable of causing obstruction to the flow in sewers or other interference with the proper operation of the sewer system and wastewater treatment works such as but not limited to ashes, bones, 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, etc., either whole or ground by garbage grinders.

(d) The following described substances, materials, waters, or waste shall be limited in discharges to the sewer system to concentrations or quantities which will not harm either the sewer system, waste water treatment works processes, or equipment, will not have an adverse effect on the underlying groundwater, or will not otherwise endanger lives, limb, public property, or constitute a nuisance. The Board may set limitations lower than the limitations established in the regulations below if, in the opinion of the Board, such more severe limitations are necessary to meet the above objectives. In forming an opinion as to the acceptability, the Board will give consideration to such factors as the quantity of subject waste in relations to flows and velocities in the sewers, materials or construction of the sewers, the wastewater treatment process employed, capacity of the wastewater treatment works, degree of treatability of the waste in the wastewater treatment works, and other pertinent factors. The limitations or restrictions on materials or characteristics of waste or wastewaters discharged to the sewer system which shall not be violated without approval of the Board are as follows:

1. Wasterwater having a temperature higher than 150 degrees Fahrenheit (65 degrees Celsius).

2. Wastewater containing petroleum oil, nonbiodegradable cutting oils, or products of mineral oil origin exceeding limits which may be established by the Board.
3. Wastewater containing floatable oils, fat, or grease.
4. Any garbage that has not been properly shredded (see 6-7-2(n)). Garbage grinders may be connected to sanitary sewers from homes, hotels, institutions, restaurants, hospitals, catering establishments, or similar places where garbage originates from the preparation of food in kitchens for the purpose of consumption on the premises or when served by caterers.
5. Any waters or wastes containing iron, chromium, copper, zinc, and similar objectionable or toxic substances to such degree that any such material received in the composite wastewater at the wastewater treatment works exceeds the limits established by the Board for such materials.
6. Any waters or wastes containing odor-producing substances exceeding limits which may be established by the Board.
7. Any radioactive wastes or isotopes of such half-life concentration as may exceed limits established by the Board.
8. Quantities of flow, concentrations, or both which constitute a "slug" as defined herein.
9. Waters or wastes containing substances which are not amenable to treatment or reduction by the wastewater treatment works, or are amenable to treatment only to such degree that the effluent from the wastewater treatment works may degrade the quality of the underlying groundwater.
10. Any water or wastes which, by integration with other water or wastes in the sewer system, may release obnoxious gases, form suspended solids which interfere with the collection system, or create a condition deleterious to structures and treatment processes.

(e) If any waters or wastes are discharged or are proposed to be discharged to the sewer system, which waters contain the substances or possess the characteristics enumerated in 6-7-5(d) and which in the judgment of the Board may have a deleterious effect upon the sewer system, wastewater treatment works, processes, equipment, or underlying groundwater, or which otherwise create a hazard to life or constitute a public nuisance, the Board may:

1. Reject the wastes.
2. Require pretreatment to an acceptable condition for discharge to the sewer system.
3. Require control over the quantities and rates of discharge.
If the Board 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 Board.

(f) Grease, oil, and sand interceptors shall be provided when, in the opinion of the Board, such devices are necessary for the proper handling of liquid wastes containing floatable grease in excessive amounts, as specified in 6-7-5(d)(3), or any flammable wastes, sand, or other harmful ingredients, except that such interceptors shall not be required for private living quarters or dwelling units. All interceptors shall be of a type and capacity approved by the Board and shall be located as to be readily and easily accessible for cleaning and inspections. In the maintaining of the interceptors, the owner(s) shall be responsible for the proper removal and disposal by appropriate means of the captured material and shall maintain records of the dates and means of disposal. Any removal and hauling of the collected materials not performed by owner(s)' personnel shall be performed by currently licensed waste disposal firms.

(g) Where pretreatment or flow equalizing facilities are provided or required for any waters or wastes, they shall be maintained continuously in satisfactory and effective operation by the owner(s) at his expense.

(h) All measurements, tests, and analyses of the characteristics of waters and wastes to which reference is made in the 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. Sampling methods, location, times, durations, and frequencies are to be determined on an individual basis subject to approval by the Board.


6-7-6 Protection from Damage
