[Ord. 338, 4-17-1989]
The purpose of this chapter is:
A.
To protect the public water supply system from contamination or pollution
by isolating within the customer's water system contaminants
or pollutants which could backflow through the service connection
into the public water supply system.
B.
To promote the elimination or control of existing cross connections,
actual or potential, between the public or consumer's potable
water system and nonpotable water systems, plumbing fixtures and sources
or systems containing substances of unknown or questionable safety.
C.
To provide for the maintenance of a continuing program of cross connection
control which will prevent the contamination or pollution of the public
and consumer's potable water systems.
[Ord. 338, 4-17-1989]
This chapter shall apply to all premises served by the public
potable water supply system of the City.
[Ord. 338, 4-17-1989; amended by 2003 Code]
The owner or official custodian shall be responsible for protection
of the public water supply system of the City from contamination due
to backflow or back siphonage of contaminants through the customer's
water service connection. If, in the judgment of the water superintendent
or his authorized representative, an approved backflow prevention
device is necessary for the safety of the public water supply system,
the water superintendent shall give notice to the consumer to install
such approved backflow prevention device at each service connection
to the premises. The consumer shall immediately install such approved
devices at the consumer's own expense; failure, refusal or inability
on the part of the consumer to install such devices immediately shall
constitute grounds for discontinuing water service to the premises
until such devices have been installed.

include all parts of the facilities beyond the service connection
used to convey water from the public water supply distribution system
to points of use.
[Ord. 338, 4-17-1989]
A.
Connections between potable water systems and other systems or equipment
containing water or other substances of unknown or questionable quality
are prohibited except when and where approved cross connection control

the superintendent and the cross connection control device inspector,
are not correctable or are intricate plumbing arrangements which make
it impractical to determine whether or not cross connections exist.
d.
Premises where, because of security requirements or other prohibitions
or restrictions, it is impossible or impractical to make a complete
cross connection survey.
e.

cutoff device in proper working order and to certify in writing to
the superintendent, at least once a year, that the device is operable.
[Ord. 338, 4-17-1989; amended by 2003 Code]
A.
The superintendent is hereby authorized and directed to deny or discontinue,
after reasonable notice in writing to the occupants thereof, the water
service to any premises wherein any connection in violation of the
provisions of this chapter is known to exist, or wherein any backflow
prevention device required by this chapter is not installed, tested,
maintained and repaired in a manner acceptable to the superintendent,
or if it is found that the backflow prevention device has been removed
or bypassed, or if an unprotected cross connection exists on the premises
or if a low pressure cutoff required by this chapter is not installed
and maintained in working order. The superintendent is further authorized
and directed to take such other precautionary measures as he may deem
necessary to eliminate any other danger of contamination of the public
water supply distribution mains and other pipes. Water service to
such property shall not be restored until such conditions have been
eliminated or corrected in compliance with the provisions of this
chapter, and until a reconnection fee of $20 is paid to the City.[1]

superintendent is assured that imminent danger of harmful contamination
of the public water supply system exists. Such action shall be followed
by written notification of the cause of disconnection. Such notification
shall be given both to the occupants of the property and to the City
Administrator. Immediate disconnection without notice to any party
can be effected to prevent actual or anticipated contamination or
