(1)
Reject
the wastes;
(2)
Require
pretreatment to an acceptable condition for discharge to the public
sewers;
(3)
Require
control over the quantities and rates of discharge; and/or
(4)
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 Section 13.213.

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 or 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

All measurements, tests and analyses of the characteristics
of waters and wastes to which reference is made in this article 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.
[The particular analyses involved will determine whether a twenty-four
(24) hour composite of all outfalls of a premise is appropriate or
whether a grab sample or samples should be taken. Normally, but not
always, B.O.D. and suspended solids analyses are obtained from twenty-four
(24) hour composites of all outfalls whereas pH’s are determined
from periodic grab samples.]
(1979 Code of Ordinances, Chapter 19, Sec. 19-28)
When required by the superintendent, the owner of any property
serviced by a building sewer carrying industrial wastes shall install
a suitable control manhole, together with such necessary meters and
other appurtenances in the building sewer to facilitate observation,
samples 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 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.
