No person shall discharge or cause to be discharged any of the following described waters or wastes to any public sewers:
(1) Any gasoline, benzene, naphtha, fuel oil or other flammable or explosive liquid, solid or
(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, create a public nuisance or
create a hazard in the receiving waters of the wastewater treatment plant.
(3) Any waters or wastes having a pH lower than 5.5 or higher than 10.0, or having any
other corrosive property capable of causing damage or hazard to structures, equipment and
personnel of the wastewater works.
(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 wastewater
facilities, 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 or plastic dishes, cups, milk containers, etc., either whole or ground by garbage
The following described substances, materials, waters or wastes shall be limited in discharges to public sewers 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, or public property or constitute a nuisance. The 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 its opinion as to the acceptability, the 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 wastewater treatment plant, degree of treatability 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 commission are as follows:
(1) Wastewater having a temperature higher than 150 degrees Fahrenheit (65 degrees
(2) Wastewater containing more than 25 milligrams per liter of petroleum oil, non
biodegradable cutting oils, or products of mineral oil origin, or containing substances which
may solidify or become viscous at temperatures between 32 degrees Fahrenheit and 150
degrees Fahrenheit (zero degrees and 65 degrees Celsius).
(3) Wastewater containing floatable oils, fat or grease.
(4) Notwithstanding the provisions of section 19-319, wastewater shall not contain any
garbage, either whole or properly shredded or ground. Garbage grinders shall not 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.
Garbage grinders so connected at the time of the passage of this amendment may continue
to be utilized but may not be replaced.
(5) Any waters or wastes containing strong acid iron pickling wastes or concentrated plating
solutions, whether neutralized or not.
(6) Any waters or wastes having concentrations of objectionable or toxic substances,
including, but not necessarily limited to, those in excess of the limits listed below, or wastes
exerting an excessive chlorine requirement to such degree that any such material received in
the composite sewage at the wastewater treatment works exceeds the limits established by
the commission as necessary after treatment of the composite sewage to meet the
requirements of the state, federal or other public agencies of jurisdiction for such discharge
to the receiving waters.
Substance (milligrams per liter)
Chromium (trivalent) 3.0
Chromium (hexavalent) 1.0
Metals (not mentioned above) 2.0
Sulfides (S -) 100.0
Sulfates (SO4 -) 500.0
Floating oil 0.0
Mercuric chloride 0.5
Phenols (not to exceed) 1.0
(7) Any waters or wastes containing odor-producing substances exceeding limits which may
be established by the commission.
(8) Any radioactive wastes or isotopes.
(9) Any waters or wastes having a pH in excess of 10.0.
(10) Materials which exert or cause:
a. Unusual concentrations of inert suspended solids, such as but not limited to
Fuller's earth, lime slurries and lime residues, or dissolved solids, such as but not
limited to sodium chloride and sodium sulfate, and wastewaters having suspended
solids concentrations in excess of 200 mg/l.
b. Excessive discoloration, such as but not limited to dye wastes and vegetable
c. Wastewaters having BOD concentrations in excess of 200 mg/l and unusual
chemical oxygen demand or chlorine requirements in such quantities as to constitute
a significant load on the sewage treatment works.
(11) Quantities of flow, concentrations or both which constitute a slug as defined in section
(12) 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.
(13) Any waters or wastes which by interaction with other waters or wastes in the public
sewer system release obnoxious gases from suspended solids which interfere with the
collection system or create a condition deleterious to structures and treatment processes.
(1) Any person found to be violating any provision of this article shall be served by the commission with written notice stating the nature of the violation and providing a reasonable time limit for the satisfactory correction thereof. A reasonable time limit shall be understood to be 30 days from the date of notice to correct unless the superintendent determines that a good faith effort to correct the violation is being made and further time is necessary. The offender shall, within the period of time stated in such notice, permanently cease all violations and take such action as is recommended or necessary to ensure there will be no recurrence of such violation. All of such work in connection therewith shall be performed by the person without delay and without expense to the town.
(2) Any person who shall continue any violation beyond the time limit shall be fined in an amount not exceeding $100.00 for each violation and not exceeding $50.00 for each additional day that any such violation shall continue. In addition, the superintendent may disconnect or otherwise act to prevent the building sewer from the premises in which said violation of the requirements of this article shall have occurred from discharging to the public sewer system.
(3) Any person violating any of the provisions of this article shall become liable to the town for any expense, loss or damage occasioned the town by reason of such violation. If the superintendent shall have caused the disconnection of a building sewer or drain from the public sewer system, the town may collect the cost of making such disconnection from any person responsible for or willfully concerned in or who profited by such violation of the requirements of this article and may thereafter refuse to permit the restoration of the former connection or of any new connection to the property concerned in the violation of this article until the claim of the town for the cost of making such disconnection shall have been paid in full plus interest and the reasonable overhead of any legal expenses incurred by the owner in connection therewith.
