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 combined sewers, or to a natural outlet approved by the Borough, subject, however, to the provisions of § 236-3 of this chapter. Industrial cooling water or unpolluted process water may be discharged, upon approval of the Borough, to a storm sewer, combined sewer, or natural outlet.
Except as hereinafter provided, no person shall discharge or cause to be discharged any of the following described waters or wastes to any public or semipublic sewer:
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 operations of the sewage treatment plant where the sanitary effluent of the Borough is treated.
F. 
Any water 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 said sewage treatment plant.
G. 
Any waters or wastes containing a toxic or poisonous 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 said sewage treatment plant.
H. 
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 said 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 by the owner at the owner's expense when, in the opinion of the inspector, 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 said inspector, and shall be 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 the owner's expense, in continuously efficient operation at all times.
The admission into the public sewers of any waters or wastes having (a) a five-day biochemical oxygen demand greater than 300 parts per million by weight, or (b) containing more than 350 parts per million by weight, or suspended solids, or (c) containing any quantity of substance having the characteristics described in § 236-8, or (d) having an average daily flow greater than 2% of the average daily sanitary sewage flow of the Borough, shall be subject to the review and approval of the said inspector. Where necessary, in the opinion of the inspector, the owner shall provide, at his expense, such preliminary treatment as may be necessary to (a) reduce the biochemical oxygen demand to 300 parts per million and the suspended solids to 350 parts per million by weight, or (b) reduce objectionable characteristics or constituents to be within the maximum limits provided for in § 236-8, or (c) 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 Borough of Leetsdale or its designated authority and of the Pennsylvania Department of Environmental Resources, and no construction of such facilities shall be commenced until said approvals are obtained in writing.
When required by the said inspector, 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 measurement of the wastes. Such manhole, when required, shall be accessible and safely located, and shall be constructed in accordance with plans approved by the Borough of Leetsdale or their designated agent. 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 §§ 236-8 and 236-11 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 § 236-12, 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.
