Pursuant to the state commission on environmental quality (TCEQ)
rules and regulations specifically stated under 30 Texas Administrative
Code section 290.449(h), it is the responsibility of the water purveyor
to ensure that an adequate cross-connection control program is in
effect.
(ORDINANCE 486-14 adopted 1/15/15)
Backpressure.
Occurs when contaminated water is under enough pressure to
flow backward into the water supply.
Backsiphonage.
Occurs when the public water system loses its water pressure
due to water line flushing and main breaks or firefighting and a vacuum
is created.
Cross connection.
A physical connection between a potable water supply and
any other source of water of unknown or unsafe quality.
Double check valve (DC).
A backflow preventer designed to control cross connections
between potable water lines and substances that are objectionable
but not a health hazard.
(Ordinance 486-14 adopted 1/15/15)
The cost of complying with these regulations shall be the responsibility
of the property owners and their lessees. These costs include but
are not limited to purchasing, installation, testing and repair of
the assembly. These costs shall also include point-of-use and premises
isolation assemblies. Any cost incurred by the city to enforce this
article is the responsibility of the property owners and their lessees.
(Ordinance 486-14 adopted 1/15/15)
It is the responsibility of all property owners and lessees
to abide by all the conditions of this article. If changes are made
to a premises plumbing system, the property owner shall notify the
plumbing inspector.
(Ordinance 486-14 adopted 1/15/15)
(a) A
certified plumbing inspector employed by or under contract with the
city shall determine the type and location of backflow assembly to
be installed within the city’s water service area.
(b) At
a minimum, a backflow prevention assembly will be required in each
of the following circumstances:

contaminate or pollute the potable water supply.
(2) When the premises has one or more cross connections.
(3) When internal cross connections are present that are not correctable.
(4) When intricate plumbing arrangements are present that make it impractical
to ascertain whether cross connections exist.

for cross connections cannot be made with sufficient frequency to
assure that cross connections do not exist.

a health hazard could result.
(8) When installation of an approved backflow prevention assembly is
deemed by an inspector to be necessary to accomplish the purpose of

approved backflow assembly at the service connection. The type of
the assembly will be commensurate with the degree of hazard as determined
by an inspector.
(12) When a building is constructed on commercial premises, and the end
use of such building is not determined or could change, a reduced
pressure principle backflow prevention assembly shall be installed
at the service connection to provide protection of the public water
supply in the event of the most hazardous use of the building.
(13) If the premises are required to have backflow prevention assemblies,
but water cannot be turned off during the testing of such assemblies,
the premises shall be equipped with dual backflow prevention assemblies
of the same type so that testing, repair and maintenance can be performed.
(14) If a point-of-use assembly has not been tested or repaired as required
by this article, a premises isolation assembly shall be required.
(15) If an inspector determines that additions or rearrangements have
been made to the plumbing system without the proper permits as required
by the plumbing code, premises isolation shall be required.
(c) Any
premises requiring multiple service connections for adequacy of supply
and/or fire protection shall have a backflow assembly on each service
connection. The assembly shall be commensurate with the degree of
potential hazard that could occur in the event of an interconnect
between any of buildings on the premises.

person commits an offense if the person owns or is in control of any
premises and knowingly fails to install and maintain backflow prevention
assemblies on said premises as required by this section.
