The following definitions and terms shall apply in the interpretation and administration of this Section.
AUXILIARY INTAKE
Any piping or other device whereby water may be secured from a source other than that normally used.
CROSS-CONNECTION
Any physical arrangement whereby a public water system is connected, directly or indirectly, with any other water supply system, sewer, drain, conduit, pool, storage reservoir, plumbing fixture, or other device which contains, or may contain, contaminated water, sewage, or other waste or liquid of unknown or unsafe quality which may be capable of imparting arrangements, jumper connections, removable sections, swivel or changeover devices through which, or because of which, backflow could occur are considered to be cross-connections.
INTERCONNECTION
Any system of piping or other arrangement whereby the public water system is connected directly with a sewer, drain, conduit, pool, storage reservoir, or other device which does or may contain sewage or other waste or liquid which would be capable of imparting contamination to the public water system.
PERSON

PUBLIC WATER SYSTEM
The waterworks system which furnishes water to the City of Hayti, Missouri, for general use and which is recognized as a public water system by the Missouri Department of Natural Resources.
B. 
The Hayti public water system is to comply with the Missouri Department of Natural Resources Rules and Regulations, 10 CSR 60-11.010, Prevention of Backflow, which pertains to cross- connections, auxiliary intakes and interconnections and establish an effective, ongoing program to control these undesirable water uses.
C. 
No person shall cause a cross-connection, auxiliary intake or interconnection to be made, or allow one to exist for any purpose whatsoever, unless the construction and operation of same has been approved by the Missouri Department of Natural Resources and the operation of such cross- connection, auxiliary intake or interconnection is at all times under the direct supervision of the Water Superintendent of the Hayti public water system.
D. 
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 Water Superintendent a statement of the non-existence of unapproved or unauthorized cross-connections, auxiliary intakes or interconnections. Such statement shall also contain an agreement that no cross-connection, auxiliary intake or interconnection will be permitted upon the premises.
E. 
It shall be the duty of the Hayti public water system 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 Water Superintendent of the Hayti public water system, and as approved by the Missouri Department of Natural Resources.
F. 
The Water Superintendent or authorized representative shall have the right to enter, at any reasonable time, any property served by a connection in the Hayti public water system for the purpose of inspecting the piping system or system thereof for cross-connections, auxiliary intakes or interconnections. 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.
G. 
Any person who now has cross-connections, auxiliary intakes 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 Water Superintendent.
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 Hayti public water system 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 manner that the two (2) systems cannot again be connected by an unauthorized person.
Where cross-connections, interconnections or auxiliary intakes are found that constitute an extreme hazard of immediate concern of contaminating the public water system, the manager of the utility shall require that immediate corrective action be taken to eliminate the threat to the public water system. Immediate steps shall be taken to disconnect the public water supply from the on-site piping system unless the hazard is corrected immediately.
H. 
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 Water Superintendent, or his/her designated representative, that the water use and protective features of the plumbing are such as to pose 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 Water Superintendent, or his/her designated representative, shall require the use of an approved protective device on the service line serving the premises to assure that any contamination that may originate in the customer's premises is contained therein. The protective devices shall be a reduced pressure zone type backflow preventer approved by the Missouri Department of Natural Resources as to manufacturer, model and size. The method of installation of backflow protective devices shall be approved by the Water Superintendent 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.
 
The Hayti public water system shall have the right to inspect and test the device or devices on an annual basis or whenever deemed necessary by the Water Superintendent or his/her designated representative. Water service shall not be disrupted to test the device 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 device or devices. Where it is found that only one (1) unit has been installed and continuance of service may be critical, the water system shall notify the Water Superintendent 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. These repairs shall be made by qualified personnel acceptable to the Water Superintendent of the Hayti public water system.
 
If necessary, water service shall be discontinued (following legal notification) for failure to maintain backflow prevention devices in proper working order. Likewise the removal, bypassing, or altering the protective device(s), or the installation thereof, so as to render the device(s) 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 Hayti public water system.
I. 
The requirements contained herein shall apply to all premises served by the Hayti public water system regardless of political subdivision boundaries and are hereby made a part of the conditions required to be met for the Hayti public water system 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 the boundaries of any political subdivision.
J. 
Whenever any person neglects or refuses to comply with any of the provisions of this policy, the Water Superintendent shall discontinue the public water system service at any premises upon which there is found to be a cross-connection, auxiliary intake or interconnection, and service shall not be restored until such cross-connection, auxiliary intake or interconnection has been discontinued.
