(4) The plumbing Inspector shall be responsible fo~ the
protection of the public potable water distribution/system from
contamlnatlon or pollution due to the backflow of contaminants
or pollutants through the water service connection. If, in the

prevention assembly is required at the customer's water service
connection; or, within the customer's private water system for
the safety of the water system, the Plumbing Inspector or his
designated agent shall give notice in writing to said customer
to install such an approved backflow prevention assembly(s) at
specific location(s) on his premises. The consumer shall
immediately install such approved assembly(s) at the consumers
own expense; and, failure, refusal or inability on the part of
the customer to install, have tested and maintain said
asscmbly(s) shall constitute a ground for discontinuing water
service to the premises until such requirements have been
satisfactcrj.ly met.

(2) The customer's system should be open for inspection at all
reasonable times to authorized representative of the City of
Schertz to determine whether cross-connections or other
structural or sanitary hazards, including violations of these
regulations, exist. When such a condition becomes known, the
Plumbing Inspector shall deny or immediately discontinue service
to the premises by providing for a physical break in the service
line until the customer has corrected the condition(s) 1n
conformance with the State and City statutes relating to
plumbing and water supplies and the regulations adopted pursuant
thereto.
(3) An approved backflow prevention assembly shall also be
installed on each service line to a customer's water system at
or near the property line or immediately inside the building
being served; but in all cases, before the first branch line
leading off the service line wherever the following conditions
exist:
(3a) In the case of prem1ses having an auxiliary water supply
which 1S not or may not be safe bacteriological or chemical
quality and which is not acceptable as an additional source by
the Plumbing Inspector, the public water system shall be
protected against backfJow from the premises by installing an
approved backflow prevention assembly in the serVlce line
appropriate to the degree of hazard.
(3b) In the case of premises on which any industrial fluids or
any other objectionable substance in handled in such a fashion
to the public water system, the public system shall be protected
against backflow from the premises by installing an approved
backflow prevention assembly in the service line appropriate to
the degree of hazard. This shall include the handling of
process water and waters originating from utility systems which
have been subject to deterioration in quality.
(3c) In the case of premises having (1) internal
cross-connection that cannot be permanently corrected or
controlled, or (2) intricate plumbing and piping arrangements or
where entry to all portions of the premises is not readily
accessible for inspection purposes, making it impracticable or

cross-connections exist, the public water svstcm shall be
protected against backflow from the premises by an approved
backflow prevention assembly in the service line.

and plating plants.
(4d) In the case of any premises where there are "uncontr:Jlled"
cross-connections either actual or potential, the public water
system shall be protected by an approved air-gap separation or
an approved pressure principle backflow prevention assembly at
the service connection

requlrements or other prohibitions or restrictions, it is
impossible or impractical to make a complete in-plant
cross-connection survey, the public water system shall be
protected against backflcw from the premises by either an
approved alr-gap separation or an approved reduced pressure
principle backflow prevention assembly on each service to the
premJses.

A cross connection is any connection between the potable water
supply and ancther water supply of unknown quality or any source
which may contain contaminating or polluting substances. All
water-hauling equipment and/or portable water mixing tanks using
water from fire hydrants or any other type outlet must use one
of the backflow prevention methods described herein to
adequately protect the potable water systems.
(b) General Requirements
(1) The customer must contact the Water/Wastewater
prlor to water usage to request an inspection of the
vehicular backflow protection installed.

(2) Fire hydrant meters will be installed at the designated fire
hydrant and locked until adequate backflow protection is
installed and the Water/Wastewater Superintendent has approved
that installation.
(3) Customers electing to permanently install an alr-gap
separation on water transporting vehicle(s) must submit design
plans to the Water/Wastewater Department. Note that all piping
should be properly braced. Also, adequate precautions should be
