CITY OF NORTH RICHLAND HILLS, TEXAS:
SECTION 1. DEFINITIONS The following words and phrases
shall have the meanings herein ascribed to them:

-1-
Domestic Sewage means water-borne wastes normally discharged
from sanitary convenience of dwellings, including apartment houses,

from swimming pools, unpolluted industrial water, such as
water drains, blow-off pipes, or cooling water from
various equipment shall not be discharged into sanitary
sewers if a closed storm sewer is available. If a closed
storm sewer is not available, such water may be discharged
into the sanitary sewer by indirect connection whereby
such discharge is cooled, if required, and flows into
the sanitary sewer at a rate not in excess of 5 gallons per
minute, provided that the waste does not contain materials
or substances in suspension or solution in violation of

ing limits established in Paragraph 0 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.
D. Except in quantities, or concentration, or with provisions as
stipulated herein, it shall be unlawful for any person or corporation or
individual, to discharge water or wastes to the sanitary sewer containing:

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;

demand greater than two hundred fifty (250) parts
per mi 11 ion;
(d) High hydrogen sulfide content, or
(e) Unusual flow and concentration shall be preteated

Hills Sewer System if such wastes can cause damage to
collection facilities, impair the processes, incur
treatment cost exceeding those of normal sewage, or

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 North Richland Hills prior
to admission of said waste into a sanitary sewer.
B. Plans, specifications, or any other pertinent information
relating to proposed preliminary treatment and control facilities shall be
submitted for the approval of the City of North Richland Hills, and no
construction of such facilities shall be commenced until approval 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
industrial wastes into a sanitary sewer; and,
(3) An accessible entry so that any authorized employee
of the City of North Richland Hills may readily and
safely measure the volume and samples of the flow prior
to the admission of said industrial wastes into a
sanitary sewer.
C. When preliminary treatment and control facilities are provided
for any water or wastes, they shall be maintained continuously in satisfactory
and effective operation by the owner at his expense.
D. The Mayor and other duly authorized employees or representatives
of the City of North Richland Hills acting as his duly authorized agent and
bearing proper credentials and identification, shall be permitted to gain
-9-
access to such properties as may be necessary for the purpose of inspection;
observation, measurement, sampling and testing of sewage and/or industrial
was tes .
SECTION 4. INDUSTRIAL WASTE CHARGE FORMULA
The method of cost allocation or derivation of industrial waste
charge shall be computed by the following generalized formula:
Ci = Vo Vi + bo Bi + So Si
where Ci = charge to industrial users, $/month
Vo = unit cost of transport and treatment chargeable to volume,
$/1000 gal./month
bo =unit cost of treatment chargeable to B.O.D., $/pound/month
So = unit cost of treatment (including sludge treatment) chargeable
to SS, $/pound/month
Vi = volume of was tewater from indus tri a 1 users, gal/month
Bi = amount of B.O.D. from industrial users, pounds/month
Si = amount of SS from industrial users, pounds/month
Cost computations are based on the following economic analysis:

SECTION 5. AUTHORITY TO DISCONNECT SERVICE.
The City shall retain the right to disconnect waste disposal
service 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 City is
authorized immediately to terminate service by such measures as are
necessary to protect facilities.
B. Where any governmental agency informs the City that the
effluent from the treatment plant is no longer of a standard permitted
for release into the watercourse 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 is informed that it
can no longer continue to release their effluent into the watercourse.
The owner's waste treatment service shall remain disconnected until such
time that the owner has provided additional pretreatment 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 ordinance
shall be and the same are hereby expressly repealed, and that Ordinance
No. 406 is hereby repealed.

SECTION 7. PENALTY. Any person, firm or corporation violating
any provisions of this ordinance shall be guilty of a misdemeanor, and
shall upon conviction be fined in a sum not to exceed Two Hundred Dollars
($200.00) with each day of violation constituting a separate violation
of this ordinance.
SECTION 8. PUBLICATION. The City Secretary shall cause the
publication of the caption and penalty clause of this ordinance in two
consecutive issues of the official paper of the City of North Richland
Hills, Texas, and said ordinance shall become effective ten (10) days
after the date of its passage.
SECTION 9. SEVERABILITY. If any section, paragraph, subdivision,
clause, phrase or provision of this ordinance shall be judged invalid or
held unconstitutional, the same shall not in any manner be so construed
as to affect the validity of the remainder of this ordinance as a whole
or any part or provision thereof, other than the part so decided to be
invalid or unconstitutional.
