No person shall discharge or cause to be discharged
any stormwater, surface water, groundwater, roof runoff, subsurface
drainage, uncontaminated 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 combined sewers or storm sewers, or to a natural outlet approved
by the Sewer Inspector or other person authorized by the Municipal
Board. Industrial cooling water or unpolluted process waters may be
discharged, on approval of the Sewer Inspector or other authorized
person, to a storm sewer, combined sewer, or natural outlet.
No person shall discharge or cause to be discharged
into any public sewer or sanitary sewer any waters, wastes, or any
materials, which are prohibited by the laws, ordinances, or other
applicable rules and regulations of any contracting municipality and,
in addition thereto, and without limiting the generality of the foregoing,
any of the following:
A. Any storm or surface water, drainage, or flow from
roofs, cellars, cistern tank, springs, wells, or swimming pools, or,
except as may be permitted by the contracting municipality and the
Municipal Board, any discharge from a vehicles wash rack (unless preceded
by a grease, oil, and sand interceptor approved by the Sewer Inspector),
or wash motor or from any air-conditioning machine or refrigerator
unit.
B. Any gasoline, benzene, naphtha, fuel oil, or other
flammable or explosive liquid, solid, or gas.
C. Any waters or wastes containing toxic or poisonous
solids, liquids, or gasses in sufficient quantity, either singly or
by interaction with other wastes, to injure or interfere with any
sewage treatment process, constitute a hazard to humans or animals,
create a public nuisance, or create any hazard in the receiving waters
of the sewage treatment plant, including but not limited to cyanides,
radioactive materials, or isotopes, or other substances, the discharge
of which are either prohibited entirely or beyond certain limits as
provided in and by the ordinances, laws, rules, and regulation of
any contracting municipality receiving such waters and wastes for
treatment or by any rules, regulations, or laws of the Municipal Board
or by any applicable federal or state laws, rules, or regulations.
D. Waters or wastes containing substances which are not
amenable to treatment or reduction by the sewage treatment processes
employed, or are amenable to treatment only to such degree that the
sewage treatment plant effluent cannot meet the requirements of the
contracting municipalities or other agencies having jurisdiction over
discharge to the receiving waters.
If any waters or wastes are discharged, or are
proposed to be discharged to the public sewers, which contain the
substances and possess the characteristics described in other provisions
of this article or which may have a deleterious effect upon the sewage
works, processes, equipment, or receiving waters, or which otherwise
create a hazard to life or constitute a public nuisance, the Sewer
Inspector or other authorized person may:
A. Reject the wastes and sever the connection and cause
the removal of any sewer, sewer pipe, or drain through which such
substances are discharged;
B. Require pretreatment to an acceptable condition for
discharge to the public sewers;
C. Require control over the quantities and rates of discharge;
and/or
D. Require payment to cover the added cost of handling
and treating the wastes not covered by existing taxes or sewer charges
under the provisions of this chapter or any other law, ordinance,
rule, or regulation of the municipality or contracting municipality.
E. No action shall be taken under Subsection
A of this section unless the municipality shall give the owner or occupant of the premises at least 48 hours' notice in writing stating the action to be taken and the grounds therefor, except that such notice shall not be required if immediate action is necessary to prevent injury to the public sewer system or any part thereof in the reasonable discretion of the municipality or any authorized officer or employee of the municipality or contracting municipality.
Grease, oil, and sand interceptors shall be
provided when, in the opinion of the Municipal Board, its duly authorized
representative or the contracting municipality, they are necessary
for the proper handling of liquid wastes containing grease in excessive
amounts, or any flammable wastes, sand, or other harmful ingredients.
All measurements, tests, and analyses of the
characteristics of waters and wastes to which reference is made in
this chapter shall be determined in accordance with the latest edition
of "Standard Methods for the Examination of Water and Wastewater,"
published by the American Public Health Association, and shall be
determined at the control manhole provided, 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. Sampling shall be carried out by
customarily accepted methods to reflect the effect of constituents
upon the sewage works and to determine the existence of hazards to
life, limb, and property.
No statement contained in this article shall
be construed as preventing any special agreement or arrangement between
the municipality and any industrial concern whereby an industrial
waste of unusual strength or character may be accepted for treatment
subject to payment thereof or by the industrial concern and provided
that all requirements and conditions of any contracting municipality
are met.
All provisions of WPCF Manual of Practice No. 3, Regulation of Sewer Use, 1975, Article
V, Use of Public Sewers, and updates thereof shall be considered a part of this chapter.
