LATION OF POTABLE WATER SUPPLY, PROVIDING FOR THE
CONTROL OF CROSS-CONNECTION, BACKFLOW AND BACK-
SIPHONAGE, AND ESTABLISHING THE CROSS-CONNECTION,
BACKFLOW AND BACK-SIPHONAGE CONTROL BOARD.
WHEREAS, the existence of cross-connections, backflow, and
back-siphonage creates varying degrees of hazards to potable water
within the water main and water supply systems and the City Council
wishes to provide protections against such contamination while applying
the principle that the degree of protection should be commensurate
with the degree of hazard; and,
WHEREAS, cross-connection, backflow and back-siphonage control
requires the cooperation of the water distributors , public health
officer, plumbing inspector, and the consumers , and the City Council
desires to clearly set forth the responsibilities and duties of each.
NOW, THEREFORE, BE IT ORDAINED BY THE CITY COUNCIL OF THE CITY
OF WICHITA FALLS, TEXAS, THAT:
SECTION 1 . Section 1204 of the Plumbing Code of the City of
Wichita Falls is hereby amended to read as follows :
SECTION 1204 . PROTECTION OF POTABLE WATER SUPPLY
1204 .1 -- BACKFLOW
Every water outlet and the water distribution system shall be
protected against backflow. The preferred method of protecting the
water outlet from backflow shall be the method of having the outlet
end from which the water flows spaced a distance above the flood-
level rim of the receptacle into which the water flows, sufficient
to provide a "minimum required air gap" as defined in American
National Standard Institute A 112 .1. 2 . Where it is not possible to
provide a minimum air gap, the water outlet shall be equipped with
an accessibly located backflow preventer complying with Section
1204 .2 of this Code.
1204 . 2 -- APPROVAL OF DEVICES
All devices for the prevention of backflow or back-siphonage
shall meet the requirements of Table 505. Devices installed in a
potable water supply for protection against backflow shall be main-
tained in good working condition by the person or persons having
control of such devices . The plumbing inspector, having jurisdiction,
may inspect such devices, and if they are found to be defective or

A backflow preventer device which will automatically vent to
the atmosphere shall be installed in the water supply line to all
steam and hot water space heating boilers, heat exchanges and similar
devices, being supplied from the potable water system. Such
devices shall prevent back-siphonage and backflow from the heating
system into the potable supply lines , should the supply pressure
fall below the pressure in the heating system. Such devices shall
meet the requirements of Table 505, and nd shall
bear such identifica-
tion as is required by the applicable s tandard.
1204 . 4 -- BACKFLOW PREVENTER INSTALLATION
Backflow preventers shall not be buried, and backflow preventers
shall be so located as to prevent any relief openings from being
submerged. When backflow preventers are installed in vaults or
pits which extend below grade level, relief outlets shall be piped
full size directly to the outside of the vault or pit, with piping
terminating in a downward direction at a point not less than twelve
(12) inches above grade. An opening shall be provided in the vault
wall, at one-half the distance between the relief piping terminus
and grade. This opening shall be at least four times the diameter
of the relief outlet piping, or, if smaller openings are desired,
they shall be not less than four in number, each being two and one-
half (2-1/2) times the diameter of the relief outlet pipe. Sufficient
clearance from the devices on all sides shall be provided to permit
testing in place or removal for maintenance.
Vault installations are not recommended and shall be avoided,
except where necessary to protect the device from damage . In any
case, vaults shall be so constructed and equipped with positive

periodic field testing after installation in the pipe line shall be
equipped with gate valves on both the inlet and the outlet side of
the backflow preventer. In addition, test cocks shall be provided
and so located that test equipment, gauges, etc. , may be connected
to device at such points that the pressure in each pressure zone may
be detected and, in addition, a test cock shall be located upstream
of the upstream gate valve or installed in a special tapping on the
upstream side of the upstream gate valve. But, in any case, such
test cock shall be accessibly located as close to the device as
practical. Where applicable approved standards specify otherwise,
the location of test cocks shall be as specified by the standard.
SECTION 2 . Section 1205 , CROSS CONNECTION, BACKFLOW AND BACK-
SIPHONAGE CONTROL, is hereby amended to read as follows :
1205 . CROSS CONNECTION, BACKFLOW AND BACK-SIPHONAGE CONTROL.
1205 .1 -- INTENT.
(a) It is the intent of this section to recognize that there
are varying degrees of hazard to potable water within the water main and
water supply systems, and it is the intent to apply the principle that
the degree of protection should be commensurate with the degree of
hazard.
(b) The ur ose of this section is :
P P
(1) To protect the public water main against actual or
potential cross-connections, backflow and back-siphonage by isolating,
within public property or private property, contamination or pollution
that has occurred or may occur because of some undiscovered or
unauthorized cross-connection on public property or private property.
(2) To protect the water supply system within the public
or private property against actual or potential cross-connections,
backflow and back-siphonage by requiring such air gaps , vacuum
breakers, backflow preventers, reduced pressure principle backflow
preventers, and special devices as required by this section or other
applicable regulations.
(3) To eliminate cross-connections, backflow and back-
siphonage of any other source of water or process water used for any
purpose whatsoever which may jeopardize the safety of the water supply
or which may endanger the health and welfare of the general public.
(4) To establish a cross-connection, backflow and back-
siphonage control program.
(c) A cross-connection is defined as any physical connection
or arrangement of pipes between two otherwise separate water supply
systems, one of which contains potable water and the water, water of
unknown or questionable safety, whereby water may flow from one
system to the other, the direction of flow depending on pressure
differential between the two systems.
1205. 2 -- DEFINITIONS
In addition to the definitions contained in Chapter III of the
Wichita Falls Plumbing Code, the following special definitions shall
apply:
BACK-SIPHONAGE BACKFLOW means a reversal of the normal direction
of flow in the pipeline due to a negative pressure (vacuum) being
created in the supply line with the backflow source subject to
atmospheric pressure.
3
BACKFLOW PREVENTER means a device to prevent backflow. As there
are two conditions of backflow, the device should be identified by
the conditions which it is designed to prevent. (See Back Pressure
Backflow Preventer, Backflow Preventer Reduced Pressure Type,
Back-Siphonage Backflow Preventer) .
BACK PRESSURE BACKFLOW PREVENTER means a device to prevent
backflow due to a general condition in which the pressure in the
system becomes greater than the supply pressure, the system being
above atmospheric pressure . (See also Check Valves Assembly .)
BACKFLOW PREVENTER, REDUCED PRESSURE TYPE means a device having
dual check valves force-loaded, or biased, to a normally closed
position, a chamber or zone between the check valves in which
pressure is normally lower than the supply pressure, a relief or
vent valve force loaded to a normally open position located in the
zone to automatically open a passage between the zone and the atmosphere,
should the zone pressure, for any reason, tend to equalize with or
exceed the supply pressure .
BACK-SIPHONAGE BACKFLOW PREVENTER, GENERAL means a device or a
combination of devices for preventing back-siphonage in a water
supply line.
CHECK VALVES ASSEMBLY means a combination of spring and weight
loaded check valves with resilient discs for the intended purpose
of preventing back pressure backflow in a water supply line.
Assembly is usually furnished with test cocks for field testing the
tightness of the check valves . Some assemblies include a "Vacuum
Breaker" to admit atmospheric air downstream of the assembly.
CONSUMER means any person, firm or corporation using or receiving
water from the City's water system
CONTAMINANTS means any foreign material, solid or liquid, not
common to the potable water supply which makes the water unfit or
undesirable for human or animal consumption.
CONTAMINATION means the admission of contaminants into the
potable water supply .
1205 . 3 -- REGULATIONS
(a) No water service connections to any premises shall be
installed or maintained unless the potable water and water supply
are protected against actual or potential contamination.
(b) No cross connection shall be permitted to be made between
any system of piping supplied by water from the main of the Public
Utilities Department, and any other source of supply, either public
or private, or any secondary supplies known to be unsafe for
drinking water, such as shallow wells , reused industrial supplies,
raw surface water or swimming pools .
(c) Where City water is used as an auxiliary supply to a roof or
suction tank, which is also supplied by water from any other source,
such tank shall not be of the pressure type, but open. The delivery
of City water shall be above the tank flow line and controlled by
some type of automatic valve .
4
(d) It shall be unlawful to maintain storage tanks supplied
only with City water, unless the tanks are satisfactorily built,
and covered so as to prevent the entrance of contamination. They
shall also be subject to periodical inspection by the Inspection
Department, and maintained in a manner wholly satisfactory to the
standards and requirements of the State Department of Health. Pumps
taking suction from the City supply, serving such building storage,
shall be installed or operated only upon permit from the Public
Utilities Department, subject to their approval as to size, capacity
and valving arrangements .
(e) It shall be unlawful for anyone to interconnect private
supplies, including deep well systems, with the Public Utilities
Department water system.
(f) Should any system supplied by City water be operated in
violation of any provision of this article, it shall be the duty
of the Public Utilities Department to completely disconnect all
service lines serving such system until this section is properly
complied with. Any cost of such disconnection and the estimated
cost of reconnection must be paid by the consumer before service
shall be restored. The Public Utilities Department shall not
disconnect the water system unless the procedures set forth in
Subsection 103 . 4 have been complied with by the plumbing inspector.
