Industrial cooling water or unpolluted process waters may be discharged, upon approval of the Superintendent or other public authority, to a storm sewer or natural outlet.
Except as hereinafter provided, no person shall discharge or cause to be discharged to any public sewer any of the following described waters or wastes:
A. 
Any liquid or vapor having a temperature higher than 150° F.
B. 
Any water or waste which may contain more than 100 parts per million by weight of fat, oil or grease.
C. 
Any gasoline, benzene, naphtha, fuel oil or other flammable or explosive liquid, solid or gas.
D. 
Any garbage that has not been properly shredded.
E. 
Any ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar, plastics, wood, paunch manure or any other solid or viscous substance capable of causing obstruction to the flow in sewers or other interference with the proper operation of the sewage works.

Any waters or wastes having a pH lower than 5.5 or higher than 9.0 or having any other corrosive property capable of causing damage or hazard to structures, equipment and personnel of the sewage works.
G. 
Any waters or wastes containing a toxic, poisonous or radioactive substance 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 of the sewage treatment plant.

Any waters or wastes containing suspended solids of such character and quantity that unusual attention or expense is required to handle such materials at the sewage treatment plant.
I. 
Any noxious or malodorous gas or substance capable of creating a public nuisance.
A. 
Grease, oil and sand interceptors shall be provided when, in the opinion of the Superintendent, 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 Superintendent and shall be so located as to be readily and easily accessible for cleaning and inspection.
B. 
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 and watertight.
Where installed, all grease, oil and sand interceptors shall be maintained by the owner at his expense in continuously efficient operation at all times.
A. 
The admission into the public sewers of any waters or wastes having any of the following characteristics shall be subject to the review and approval of the Superintendent:
(1) 
A five-day biochemical oxygen demand greater than 300 parts per million by weight.
(2) 
More than 350 parts per million by weight of suspended solids.
(3) 
Any quantity of substances having the characteristics described in § 102-29.
(4) 
An average daily flow greater than 2% of the average daily sewage flow of the town.

Where necessary in the opinion of the Superintendent, the owner shall provide at his expense such preliminary treatment as may be necessary to accomplish any of the following:
(1) 
Reduce the biochemical oxygen demand to 300 parts per million and the suspended solids to 350 parts per million by weight.
(2) 
Reduce objectionable characteristics or constituents to within the maximum limits provided for in § 102-29.
(3) 
Control the quantities and rates of discharge of such waters or wastes.
C. 
Plans, specifications and any other pertinent information relating to proposed preliminary treatment facilities shall be submitted for the approval of the Superintendent or other public authority, and no construction of such facilities shall be commenced until said approvals are obtained in writing.
Where preliminary treatment 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 Superintendent, the owner of any property served by a building sewer carrying industrial wastes shall install a suitable control manhole in the building sewer to facilitate observation, sampling and measurements of the wastes. Such manhole, when required, shall be accessibly and safely located and shall be constructed in accordance with plans approved by the Superintendent. 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 §§ 102-29 and 102-32 shall be determined in accordance with Standard Methods for the Examination of Water and Sewage and shall be determined at the control manhole provided for in § 102-34 or upon suitable samples taken at said control manhole. 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 to the point at which the building sewer is connected.
No statement contained in this article shall be construed as preventing any special agreement or arrangement between the Town or other public authority and any industrial concern whereby an industrial waste of unusual strength or character may be accepted by the Town or other public authority for treatment, subject to payment therefor by the industrial concern.
