No person shall discharge or cause to be discharged any stormwater, surface water, groundwater, roof runoff, subsurface drainage, cooling water or unpolluted industrial process waters to any sanitary sewer.
Stormwater and all other unpolluted drainage shall be discharged to such sewers as are specifically designated as storm sewers, or to a watercourse approved by the Enforcement Officer. Industrial cooling water or unpolluted process waters may be discharged, upon approval of the Enforcement Officer to a storm sewer or watercourse.
A. 
Except as hereinafter provided, no person shall discharge or cause to be discharged any of the following described waters or wastes to any public sewer:
(1) 
Any liquid or vapor having a temperature higher than 150º F. (65º C.).
(2) 
Any waters or wastes which contain grease or oil or other substance that will solidify or become discernibly viscous at temperatures between 32º and 150º F.
(3) 
Any waters or wastes containing fats, wax, grease, or oils, whether emulsified or not, exceeding an average of 50 parts per million (417 pounds per million gallons) of ether soluble matter.
(4) 
Any gasoline, benzine, naphtha, fuel oil, mineral oil or other flammable or explosive liquid, solid or gas.
(5) 
Any noxious or malodorous gas such as hydrogen sulfide, sulfur dioxide, or nitrous oxide or other substance which, either singly or by interaction with other wastes, is capable of creating a public nuisance or hazard to life or of preventing entry into sewers for their maintenance and repair.
(6) 
Any garbage that has not been properly shredded. The installation and operation of any garbage grinder equipped with a motor of 3/4 horsepower or greater shall be subject to the review and approval of the Enforcement Officer.
(7) 
Any ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar, plastic, cardboard, wood, paunch manure, hair and fleshings, entrails, lime slurry, lime residues, beer distillery slops, whey, chemical residues, paint residues, cannery wastes, bulk solids, or any other viscous substance capable or causing obstruction to the flow of the sewers, or other interference with the proper operation of the sewage system.
(8) 
Any waters or wastes, acid or alkaline in reaction, having corrosive properties capable of causing damage or hazard to structures, equipment and personnel of the sewage works. Free acids and alkalies must be neutralized at all times, within a permissible pH range of 6.5. to 9.5.
(9) 
Any cyanides, in excess of two parts per million by weight as CN.
(10) 
Any long half-life (over 100 days) of toxic radioactive isotopes, without a special permit.
(11) 
Any waters or wastes that for a duration of 15 minutes has a concentration greater than five times that of "normal" sewage as measured by suspended solids and BOD and/or which is discharged continuously at a rate exceeding 1,000 gallons per minute except by special permit. Normal sanitary sewage shall be construed to fall within the following ranges:
Constituents
Permissible Range
(parts per million)
Suspended solids
180 to 350
BOD
140 to 300
Chlorine requirement

(12) 
Any stormwater, roof drains, spring water, cistern or tank overflow, footing drain, or the contents of any privy vault, septic tank or cesspool, or the discharge of effluent from any air-conditioning machine or refrigeration unit.
B. 
No person shall discharge or cause to be discharged any waters or wastes containing a toxic or poisonous substance, a high chlorine demand or suspended solids in sufficient quantity to injure or interfere with any sewage treatment process, constitute a hazard to humans or animals or create any hazard in the receiving waters or the effluent of the Town water pollution control plant. Such toxic substances shall be limited to the average concentrations listed hereinafter in the sewage as it arrives at the plant and at no time shall the hourly concentration at the plant exceed three times the average concentration. If concentrations listed are exceeded, individual establishments will be subject to control in volume and condensation of sewage by the Town Engineer and Town Board.

A. 
Town Engineer to specify. Grease, oil and sand interceptors shall be provided when the above-set limits for those substances are exceeded or when, in the opinion of the Town Engineer, they are necessary for the proper handling of liquid wastes containing grease in excessive amounts or any flammable wastes, sand, and 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 Town Engineer, and shall be located as to be readily and easily accessible for cleaning and inspection.
B. 
Construction of interceptors. Grease and oil interceptors shall be constructed of impervious materials capable of withstanding abrupt and extreme changes in temperature. They shall be of substantial construction, watertight and equipped with easily removable covers which, when bolted in place, shall be gastight.
C. 
Owner's responsibility to maintain. Where installed, all grease, oil and sand interceptors shall be maintained by the owner, at his expense, in continuously efficient operation at all times and shall be readily accessible and open to inspection by the Enforcement Officer at any time.
A. 
Review by Town Engineer. The admission into the public sewers of any waters or wastes having a five day biochemical oxygen demand greater than 300 parts per million, or containing more than 15 parts per million of chlorine requirement, or containing any quantity of substances having the characteristics described in § 166-20, or having an average daily flow greater than 2% of the average daily sewage flow which enters any sewage treatment plant of the Town, shall be subject to the review and approval of the Town Engineer. Where necessary in the opinion of the Town Engineer, the owner shall provide, at his expense, such preliminary treatment as may be necessary to:
(1) 
Reduce the biochemical oxygen demand to 300 parts per million and the suspended solids to 350 parts per million by weight; or
(2) 
Reduce the chlorine requirements to 15 parts per million; or
(3) 
Reduce objectionable characteristics or constituents to within the maximum limits provided far in § 166-20; or
(4) 
Control the quantities and rates of discharge of such waters or wastes. Plans, specifications, and any other pertinent information relating to proposed preliminary treatment facilities shall be submitted for the approval of the Town Engineer and the Health Department of the State of New York, and no construction of such facilities shall be commenced until said approvals are obtained in writing. Failure to comply with one or more of the remedial procedures as required by the Town Engineer will constitute a violation of this chapter.
B. 
Owner to bear cost. 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.
When required by the Town Engineer, the owner of any property served by building lateral carrying industrial wastes shall install a suitable control manhole in the building lateral to facilitate observation, sampling and measurement of the wastes. Such manhole, when required, shall be accessibly and safely located, and shall be constructed in accordance with plans approved by the Town Engineer. 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.
All measurements, tests, and analyses of the characteristics of waters and wastes to which reference is made in §§ 166-20 and 166-22 shall be determined, in accordance with Standard Methods for the Examination of Water and Sewage, from suitable samples taken at control manhole provided for in § 166-23. In the event that no special manhole has been required, the control manhole shall be considered to be the nearest downstream manhole in the public sewer from the point at which the building lateral is connected.
No statement contained in this article shall be construed as preventing any special agreement or arrangement between the Town and any industrial concern whereby an industrial waste of unusual strength or character may be accepted by the Town for treatment, subject to payment therefor by the industrial concern.
All of the preceding standards are to apply at the point where the industrial wastes are discharged into the sewage works and any chemical or mechanical corrective treatment required must be accomplished to practical completion before the wastes reach that point. The laboratory methods used in the examination of all industrial wastes shall be those set forth in the latest edition of Standard Methods for the Examination of Water and Sewage, published by the American Public Health Association. However, alternate methods for the analysis of industrial wastes may be used subject to mutual agreement between the Town Board and the producer of such wastes. The frequency and duration of the sampling of any industrial waste shall not be less than once a quarter, for 24 hours. However, more frequent and longer periods may be required at the discretion of the Town Board.
