SECTION 2. PROHIBITED WASTES.
A. No person shall discharge, or cause to be discharged, into
any sanitary sewer any of the following described substances,
material, waters, or wastes:
(1) Any liquid or vapor having a temperature higher than
one hundred fifty (150) degrees Fahrenheit (sixty-
five (65) degrees Centigrade), or any discharge
which causes the temperature of the total treatment
plant influent to increase at a rate of ten (10)
degrees' Fahrenheit or more per hour or a combined
total increase to a plant influent temperature of
one hundred ten (110) degrees Fahrenheit;
(2) Any water or wastes which contain wax, grease or oil,

(5) Any garbage not within definition of properly shredded
garbage as defined in SECTION 1 hereof;
(6) Any noxious or malodrous substance and which can
form a gas, which either singly or by interaction
with other wastes, is capable of causing objectionable

tration exceeding limits established in paragraph B.
of this section; or creates any other condition
deleterious to structures or treatment processes; or
requires unusual provisions, attention, or expense to
handle such materials.
B. Except in quantities, or concentration, or with provisions as
stipulated herein, it shall be unlawful for any person, corporation or
individual, to discharge water or wastes to the sanitary sewer
containing:
(1) Free or emulsified oil and grease exceeding on
analysis an average of one hundred (100) parts per
million (eight hundred thirty-three (833) pounds
per million gallons) of either or both or com-
binations of free or emulsified oil and grease, if,
in the opinion of the manager, it appears probable
that such wastes:
(a) Can deposit grease or oil in the sewer lines
in such a manner as to clog the sewers;
(b) Can over-load skimming and grease handling
equipment;
(c) Are not amenable to bacterial action and will
therefore pass to the receiving waters without
being affected by normal sewage treatment
processed; or,
(d) Can have deleterious effects on the treatment
process due to the excessive quantities.
(2) Acids or alkalies which attack or corrode sewers
or sewage disposal structures, or have a pH value
lower than 5.5 or higher than 9.5;

parts per million by weight as CN in the wastes from
any outlet into the public sewers;
(4) Materials which exert or cause:
(a) Unuaual concentrations of solids or composition;
as for example; total suspended solids of greater
than 250 parts per million of inert nature or
such as Fuller's Earth and/or total dissolved
solids such as sodium chloride, or sodium sulfate;
(b) Excessive discoloration;
(c) Biochemical oxygen demand or an immediate oxygen
demand greater than two hundred (250) parts per
million;
(d) High hydrogen sulfide content, or
(e) Unusual flow and concentration shall be pretreated
to a concentration acceptable to the Rouhd,° Rock
Water and Sewer System if such wastes can cause
damage to collection facilities, impair the
processes, incur treatment cost exceeding those
of normal sewage, or render the water unfit for
stream disposal or industrial use.
SECTION 3. PRETREATMENT AND CONTROL OF INDUSTRIAL WASTES.
A. Persons or owners discharging industrial wastes which exhibit
any of the prohibited wastes set out in this ordinance shall be
required to pretreat said wastes or otherwise dispose of such
wastes so as to make the remaining waste acceptable to the City of
Round Rock prior to admission of said waste into a sanitary sewer.
B. Plans, specifications, and any other pertinent information
relating to proposed preliminary treatment and control facilities
shall be submitted for the approval of the City of Round Rock, and
no construction of such facilities shall be commenced until ap-
proval is obtained in writing. Preliminary treatment and control
facilities shall be constructed so as to provide all of the following:
(1) Prevention of prohibited waste from entering a
sanitary sewer;
(2) Control of the quantities and rates of discharge of
26
industrial wastes`into a'dat►itary sewer; and ,
(3) An accessible entry so that any authorized employee of
the City of Round Rock may readily and safely measure the
volume and samples of the flow prior to the admission of
C. When preliminary treatment and control facilities are pro-
vided for any water or wastes, they shall be maintained continuously
in satisfactory and effective operation by the owner at his expense.
D. The manager and other duly authorized employees of the City of
Round Rock acting as his duly authorized agent and bearing proper cre-
dentials and identification, shall be permitted to gain access to such
properties as may be necessary for the purpose of inspection,
observation, measurement, sampling and testing of sewage and/or
industrial wastes.
SECTION 4. SURCHARGE FOR WASTES OF ABNORMAL STRENGTH.
The service charge for any person, firm, owner or corporation
discharging wastes into the system is twenty-five per cent (25%) of the
total cost of water purchased by the owner for that billing period
provided that the City meter is the only source of water used by the
owner and provided that the B. 0. D. in the waste water or the sus-
pended materials does not exceed the normal concentration of two hun-
dred fifty (250) ppn.
When either the B. O. D. or the suspended solids or both are found
to exceed the stated two hundred fifty (250) ppn at the point entering
the City's system, a surcharge shall be applied to the billing rate by
multiplying the normal base rate by the factor obtained from dividing the
actual measured B. O. D. by two hundred fifty and also by the factor obtained
from dividing the actual measured suspended solids by two hundred -fifty;
each such factor to be applied individually and only when greater than
one. The surcharge will be made for each factor that exceeds one and
shall be additive.
The determination of B. 0. D. and suspended materials shall be by
an independent laboratory selected by the City. The time of selection
of the sample shall be at the sole discretion of the City. The app-
licable surcharge determined by such tests shall be retro -active for
two billing periods and shall continue for six (6) billing periods
unless subsequent tests determine that the surcharge should be further
increased.
27
•
When any such tests made at the'discretionof the City shows that'
a surcharge shall be applied, continued or increased over the base rates,
which ever is applicable, then the owner shall be billed at the rate of
Five Dollars ($5.00) for each test to cover the costs of sampling,
mailing and handling plus the laboratory fees. When a surcharge is in
effect, the test will be made at least each fifteen (15) days. When such
tests made at the discretion of the City reveals that the surcharge is no
longer applicable, then no costs will be made to the owner for such test
or tests.
SECTION 5. AUTHORITY TO DISCONNECT SERVICE.
The City shall retain the right to disconnect waste disposal ser-
vice in the following circumstances:
A. Where acids or chemicals damaging to sewer lines or treatment
processes are released to the sewer causing rapid deterioration of
these structures or interfering with proper treatment of sewage, the
manager is authorized immediately to terminate service by such mea-
sures as are necessary to protect the facilities;
B. Where any governmental agency informs the City that the
effluent from the treatment plant is not longer of a standard per-
mitted for surface runoff and it is found that the owner is delivering
waste water to the City's system that cannot be sufficiently diluted
by mixing with the City's waste or requires treatment that is not
provided by the City as normal domestic treatment. In this instance,
the City shall immediately supply the owner with the governmental
agencies report and provide the owner with all pertinent information.
The owner's waste line will then be disconnected when the City's
informed that it can no longer continue to release their effluent for
surface runoff. The owner's waste treatment service shall remain dis-
connected until such time that the owner has provided additional pre-
treatment facilities designed to remove the objectionable cause from
owner's industrial wastes;
C. Where the owner delivers his waste water at an uncontrolled,
variable rate in sufficient quantity that it causes an imbalance in
the sewage treating system.
SECTION 6. REPEALER. All ordinances and parts of ordinances
inconsistent with or in conflict with the provisions of this ordi-
nance shall be and the same are hereby expressly repealed.
