and interconnections and establish an effective, ongoing program to
control these undesirable water uses.
[Ord. No. 14.514 §3, 9-3-1991]
No person shall cause a cross-connection, auxiliary supply or

all times under the direct supervision of the Superintendent of Utilities
of the Department of Utilities.
[Ord. No. 14.514 §4, 9-3-1991]
Any person whose premises are supplied with water from the public
water system, and who also has on the same premises a separate source
of water supply or stores water in an uncovered or unsanitary storage
reservoir from which the water stored therein is circulated through
a piping system, shall file with the City of California a statement
of the non-existence of unapproved or unauthorized cross-connections,
auxiliary supplies, or interconnections. Such statements shall also
contain an agreement that no cross-connection, auxiliary supply or
interconnection will be permitted upon the premises.
[Ord. No. 14.514 §5, 9-3-1991]
It shall be the duty of the Department of Utilities to cause
inspections to be made of all properties served by the public water
system where cross-connections with the public water system are deemed
possible. The frequency of inspections and reinspections based on
potential health hazards involved shall be established by the Department
of Utilities, and as approved by the Missouri Department of Natural
Resources.
[Ord. No. 14.514 §6, 9-3-1991]
The Superintendent of Utilities or authorized representative
shall have the right to enter, at any reasonable time, any property
served by a connection in the Department of Utilities for the purpose
of inspecting the piping system or systems thereof for cross-connections,
auxiliary supplies or inter-connections. On request, the owner, lessee
or occupant of any property so served shall furnish to the inspection
agency any pertinent information regarding the piping system or systems
on such property. The refusal of such information or refusal of access,
when requested, shall be deemed evidence of the presence of cross-connections.
[Ord. No. 14.514 §7, 9-3-1991]
A.
Any
person who now has cross-connections, auxiliary supplies or interconnections
in violation of this policy shall be allowed a reasonable time within
which to comply with the provisions of this policy. After a thorough
investigation of existing conditions and an appraisal of the time
required to complete the work, the amount of time shall be designated
by the City of California.
B.
The
failure to correct conditions threatening the safety of the public
water system as prohibited by this policy and the Missouri Department
of Natural Resources Rules and Regulations, 10 CSR 60-11.010, Prevention
of Backflow, within a reasonable time and within the time limits set
by the Department of Utilities shall be grounds for denial of water
service. If proper protection has not been provided after a reasonable
time, the utility shall give the customer legal notification that
water service is to be discontinued and physically separate the public
water system from the customer's on-site piping system in such a manner
that the two (2) systems cannot again be connected by an unauthorized
person.
C.
Where
cross-connections, interconnections or auxiliary supplies are found
that constitute an extreme hazard of immediate concern of contaminating
the public water system, the Superintendent of the Department Of Utilities
shall require that immediate corrective action be taken to disconnect
the public water supply from the on-site piping system unless the
hazard(s) is (are) corrected immediately.
[Ord. No. 14.514 §8, 9-3-1991]
A.
Where
the nature of use of the water supplied a premises by the water system
is such that it is deemed:
1.
Impractical to provide an effective air-gap separation;
2.
The owner and/or occupant of the premises cannot or is not willing
to demonstrate to the official in charge of the system, or his/her
designated representative, that the water use and protective features
of the plumbing are such as to propose no threat to the safety or
potability of the water system;
3.
The nature and mode of operation within a premises are such that
frequent alterations are made to the plumbing;
4.
There is a likelihood that protective measures may be subverted,
altered or disconnected.
|
The Superintendent of Utilities, or his/her designated representative,
shall require the use of an approved backflow prevention assembly
on the service line serving the premises to assure that any contamination
that may originate in the customer's premises is contained therein.
The required backflow prevention assembly shall be commensurate with
the degree of hazard and shall be approved by the Missouri Department
of Natural Resources as to manufacturer, model and size. Appendix
C, which is on file in the office of the City Clerk, contains the
most current list of backflow prevention assemblies approved by the
Missouri Department of Natural Resources. The method of installation
of backflow protective assemblies shall be approved by the Superintendent
of Utilities prior to installation and shall comply with the criteria
set forth by the Missouri Department of Natural Resources. The installation
shall be at the expense of the owner or occupant of the premises.
|
B.
The
Department of Utilities shall have the right to require inspection
and testing of the assembly or assemblies on an annual basis or whenever
deemed necessary by the Superintendent of Utilities or his/her designated
representative. Water service shall not be disrupted to test the assembly
without the knowledge of the occupant of the premises.
Where the use of water is critical to the continuance of normal
operations or protection of life, property or equipment, duplicate
units shall be provided to avoid the necessity of discontinuing water
service to test or repair the protective assembly or assemblies. Where
it is found that only one (1) unit has been installed and continuance
of service may be critical, the official in charge of the water system
shall notify in writing the occupant of the premises of plans to discontinue
water service and arrange for a mutually acceptable time to test and/or
repair the device. The water system shall require the occupant of
the premises to make all repairs indicated promptly, and the expense
of such repairs shall be borne by the owner or occupant of the premises.
Following any repair, the unit must be retested by a State certified
backflow prevention assembly tester
C.
If
necessary, water service shall be discontinued, following legal notification,
for failure to maintain backflow prevention assemblies in proper working
order. Likewise the removal, bypassing or altering the protective
assembly/assemblies, or the installation thereof, so as to render
the assembly/assemblies ineffective shall constitute grounds for discontinuance
of water service. Water service to such premises shall not be restored
until the customer has corrected or eliminated such conditions or
defects to the satisfaction of the Department of Utilities.
[Ord. No. 14.514 §9, 9-3-1991]
The requirements contained herein shall apply to all premises served by the Department of Utilities regardless of political subdivision boundaries and are hereby made part of the conditions required to be met for the Department of Utilities to provide water service to any premises. Such action, being essential for the protection of water distribution system against the entrance of contamination which may render the water unsafe healthwise, or otherwise undesirable, shall be enforced rigidly without regard to location of the premises relative to boundaries of any political subdivision. Examples of customer premises considered to be actual or potential sources of contamination are listed in Section 705.250.
[Ord. No. 14.514 §10, 9-3-1991]
Whenever any person neglects or refuses to comply with any of
the provisions of this policy, the City of California shall discontinue
the Public Water System service at any premises upon which there is
found to be a cross-connection, auxiliary supply or interconnection,
and service shall not be restored until such cross-connection, auxiliary
supply or interconnection has been discontinued.
