§ 13.08.050. Use of the 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; except stormwater runoff from limited areas, which stormwater may be polluted at times and/or cooling water may be discharged to the sanitary sewer by permission of the Juneau Utility Commission.

B.

Prohibitions and Limitations. Except as provided in this chapter, no person shall discharge or cause to be discharged any of the following described waters or wastes to any public sewer:

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 waste treatment process, constitute a hazard to humans or animals, or create a public nuisance in the receiving waters of the wastewater treatment plant;

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 of the wastewater works;

4.

Any waters or wastes having a pH in excess of 9.0;

5.

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 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;

6.

The following described substances, materials, waters or waste shall be limited in discharges to municipal systems to concentrations or quantities which will not harm either the sewers, wastewater treatment process or equipment, will not have an adverse effect on the receiving stream, or will not otherwise endanger lives, limb, public property or constitute a nuisance. The Juneau Utility Commission may set limitations lower than the limitations established in the regulations below if, in its opinion, such more severe limitations are necessary to meet the above objectives. In forming their opinion as to the acceptability, the Juneau Utility Commission will give consideration to such factors as the quantity of subject waste in relation to flows and velocities in the sewers, materials of construction of the sewers, the wastewater treatment process employed, capacity of the waste in the wastewater treatment plant, 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 Juneau Utility Commission are as follows:

a.

Wastewater having a temperature higher than one hundred fifty (150) degrees Fahrenheit (sixty-five (65) degrees Celsius);

b.

Wastewater containing more than twenty-five (25) mg/l of petroleum oil, nonbiodegradable cutting oils or produce of mineral oil origin;

c.

Wastewater from industrial plants containing floatable oils, fat or grease;

d.

Any garbage that has not been properly shredded. 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.

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 state, federal or other public agencies having jurisdiction of such discharge;

f.

Any waters or wastes containing odor producing substances exceeding limits which may be established by the state, federal, or other public agencies having jurisdiction of such discharge;

g.

Any radioactive wastes or isotopes of such half-life or concentration as may exceed limits established by the Juneau Utility Commission in compliance with applicable state or federal regulations;

h.

Quantities of flow, concentrations, or both, which constitute a slug as defined in this chapter;

i.

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 such degree that the wastewater treatment plant effluent cannot meet the requirements of other agencies having jurisdiction over discharge to the receiving waters;

j.

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

k.

Materials which exert or cause:

i.

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

ii.

Unusual volume of flow or concentration of waste slugs as defined in this chapter;

iii.

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

iv.

Excessive discoloration (such as, but not limited to, dye wastes and vegetable tanning solutions);

7.

The city shall comply with all the requirements of WPDES permit No. WI-0021474-07-0 and all modifications and substitutions thereof. No discharge shall be allowed into the sanitary sewerage system that is in violation of the requirements of the WPDES permit and the modifications thereof.

C.

Special Arrangements. No statements contained in this chapter shall be construed as prohibiting any special agreement between the city and any person whereby an industrial waste of unusual strength or character may be admitted to the sewage disposal works, either before or after pretreatment, provided that there is no impairment of the functioning of the sewage disposal works by reason of the admission of such wastes, and no extra costs are incurred by the city without recompense by the person, provided that all rates and provisions set forth in this chapter are recognized and adhered to.

D.

New Connections. New connections to the city's sanitary sewer system will be allowed only if there is available capacity in all of the downstream wastewater collection and treatment facilities. The determination as to such available capacity shall be in the sole discretion of the city and the approving authority.
