§ 225-19. Use of public sewers.

A. 

Sanitary sewers. 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 any sanitary sewer.

B. 

Inspections. Village personnel will make inspections throughout the Village for sump pump connections to sanitary sewers and illegal downspout connections. Violations will be reported to the approving authority.

C. 

Storm sewers. Stormwater and all other unpolluted drainage shall be discharged to such sewers as are specifically designated as storm sewers or to a natural outlet approved by the approving authority. Unpolluted industrial cooling water or process waters may be discharged on approval of the approving authority and other regulatory agencies to a storm sewer or natural outlet.

D. 

Prohibitions and limitations. Except as hereinafter provided, no person shall discharge or cause to be discharged any of the following described water or wastes to any public sewer:

(1) 

Gasoline, benzene, naphtha, fuel oil or other flammable or explosive liquid, solid or gas.

(2) 

Water 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 waste treatment or sludge disposal process, constitute a hazard to humans or animals or create a public nuisance in the receiving waters of the wastewater treatment facilities.

(3) 

Water or wastes having a pH lower than 6.0 or in excess of 9.0 or having any other corrosive property capable of causing damage or hazard to structures, equipment and personnel of the wastewater facilities.

(4) 

Solid or viscous substances in quantities or of such size capable of causing obstruction to the flow in public sewers or other interference with the proper operation of the wastewater facilities, 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, etc., either whole or ground by garbage grinders.

(5) 

The following described substances, materials, water or wastes shall be limited in discharges to municipal systems to concentrations or quantities which will not harm the sewers, wastewater treatment process or equipment, will not have an adverse effect on the receiving stream or will not otherwise endanger lives, limb or public property or constitute a nuisance. The approving authority may set limitations more stringent than the limitations established in the regulations below if, in its opinion, such limitations are necessary to meet the above objectives. In forming its opinion as to the acceptability, the approving authority will give consideration to such factors as the quantity of subject waste in relation to flows and velocities in the sewers, materials or construction of the sewers, the wastewater treatment process employed, the capacity of the wastewater treatment facilities, the degree of treatability of the waste in the wastewater treatment facilities and other pertinent factors. The limitations or restrictions on materials or characteristics of waste or wastewaters discharged to the sanitary sewer, which shall not be violated without approval of the approving authority, are as follows:

(a) 

Wastewater having a temperature higher than 150º F. (65º C.).

(b) 

Wastewater containing more than 25 milligrams per liter of petroleum oil, nonbiodegradable cutting oils or product of mineral oil origin.

(c) 

Wastewater from industrial plants containing floatable oil, fat or grease.

(d) 

Garbage that has not been properly shredded or any unground garbage. 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.

(e) 

Water or wastes containing iron, chromium, copper, zinc and similar objectionable, nonconventional or toxic substances to such degree that any such material received in the composite wastewater at the wastewater treatment facility exceeds the levels established by the federal, state and approving authority.

(f) 

Water or wastes containing odor-producing substances exceeding limits that may be established by the approving authority or limits established by any federal or state statute, rule or regulation.

(g) 

Radioactive wastes or isotopes of such half-life or concentrations as may exceed limits established by the approving authority in compliance with state or federal regulations.

(h) 

Water or wastes containing substances that are not amenable to treatment or reduction by the wastewater treatment processes employed or are amenable to treatment only to such degree that the wastewater treatment plant effluent cannot meet the requirements of other agencies having jurisdiction over discharge to the receiving waters.

(i) 

Water or wastes that, by interaction with other water or wastes in the public sewer system, release obnoxious gases, form suspended solids that interfere with the collection system, or create a condition deleterious to structures and treatment processes.

(j) 

Materials that exert or cause:

[1] 

Unusual BOD, chemical oxygen demand or chlorine requirements in such quantities as to constitute a significant load on the wastewater treatment facilities.

[2] 

Unusual volume of flow or concentration of wastes constituting slugs, as defined herein.

[3] 

Unusual concentrations of inert suspended solids (such as fuller's earth, lime slurries and lime residues) or of dissolved solids (such as, but not limited to, sodium sulfate).

[4] 

Excessive discoloration (such as dye wastes and vegetable tanning solutions).

(k) 

Incompatible pollutants in excess of the allowed limits as determined by local, state and federal laws and regulations by the Environmental Protection Agency (EPA), 40 CFR 403, as amended from time to time.

E. 

No person shall cause or permit a discharge into the sanitary sewers which would cause a violation of the municipality's WPDES permit.

F. 

Special arrangements. No statement contained in this article shall be construed as prohibiting any special agreement between the approving authority and any person whereby a waste of unusual strength or character may be admitted to the wastewater facilities, either before or after pretreatment, provided that there is no impairment of the functioning of the wastewater facilities by reason of the admission of such wastes and no extra costs are incurred by the approving authority without recompense by the person, and further provided that all rates and provisions set forth in this article are recognized and adhered to.
