(a) Purpose.
(1) To protect the public water supply system from contamination due to backflow or backsiphonage.
(2) To prohibit, eliminate, contain, isolate, or control cross connections between the public water supply system and non-potable water systems, plumbing fixtures, and industrial process systems or other systems which introduce or may introduce contaminants into the public water system or the consumer’s water system.
(3) To provide policy for the maintenance of a continuing program of cross connection control which will prevent the contamination of the public water supply system.
(b) Application. This article shall apply to all consumer’s water systems. It is the intent of the city or its authorized representative to reasonably interpret the ordinance and recognize the varying degrees of hazard and to apply the principle that the degree of protection shall be commensurate with the degree of hazard. The city may also require cross connection control devices at the service connections of other KDHE permitted public water supply systems served by the city.
(Ord. 208; Code 2021)
(a) No water service connection shall be installed or maintained to any premises where actual or potential cross connections to the public water supply system may exist unless such actual or potential cross connections are abated or controlled to the satisfaction of the city or its authorized representative.
(b) No connection shall be installed or maintained whereby an auxiliary water supply may enter a public water supply system.
(c) If, in the judgment of the city or its authorized representative, cross connection protection is required through either piping modification or installation of an approved backflow prevention device, due notice shall be given to the consumer. The consumers shall immediately comply by providing the required protection at their expense. Failure or refusal or inability on the part of the consumer to provide such protection shall constitute grounds for the discontinuation of water service to the premises until such protection has been provided.
(Ord. 208; Code 2021)
(a) An approved backflow prevention device shall be installed on each service line to a consumer’s water system serving premises where, in the judgment of the city or its authorized representative or the KDHE, actual or potential cross connections exist. The type and degree of protection required shall be commensurate with the degree of hazard and/or type of contamination that may enter the public water supply system.
(b) An approved air gap separation or reduced pressure principle backflow prevention device shall be installed at the service connection or within any premises where, in the judgment of the city or its authorized representative or the KDHE, the nature and extent of activities on the premises, or the materials used in connection with the activities, or materials stored on the premises, would present a health hazard or contamination of the public water supply system from a cross connection. This includes but is not limited to the following situations:
(1) Premises having an auxiliary water supply, unless the quality of the auxiliary supply is acceptable to the city or its authorized representative and the KDHE.
(2) Premises having internal plumbing arrangements, which make it impractical to ascertain whether or not, cross connections exist.
(3) Premises where entry is restricted so that inspections for cross connections cannot be made with sufficient frequency or at sufficiently short notice to assure the cross connections do not exist.
(4) Premises having a repeated history of cross connections being established or re- established.
(5) Premises, which due to the nature of the enterprise therein, are subject to recurring modification or expansion.
(6) Premises on which any substance is handled under pressure so as to permit entry into the public water supply system, or where a cross connection could reasonably be expected to occur. This shall include the handling of process waters and cooling waters.
(7) Premises where toxic or hazardous materials are handled.
(c) The following types of facilities fall into one or more of the categories or premises where an approved air gap separation or reduced pressure principle backflow prevention device may be required by the city or its authorized representative or the KDHE to protect the public water supply and must be installed at the following (but not limited to) facilities unless all hazardous or potentially hazardous conditions have been eliminated or corrected by other methods to the satisfaction of the city or its authorized representative and the KDHE:
(1) Agricultural chemical facilities
(2) Auxiliary water systems, wells
(3) Boilers
(4) Bulk water loading facilities
(5) Car washing facilities
(6) Chemical manufacturing, processing, compounding or treatment plants
(7) Chill water systems
(8) Cooling towers
(9) Feedlots
(10) Fire protection systems
(11) Hazardous waste storage and disposal sites
(12) Hospitals, mortuaries, clinics or others as discovered by sanitary surveys
(13) Irrigation and sprinkler systems
(14) Laundries and dry cleaning
(15) Meat processing facilities
(16) Metal manufacturing, cleaning, processing and fabricating plants
(17) Oil and gas production, refining, storage or transmission properties
(18) Plating plants
(19) Power plants
(20) Research and analytical laboratories
(21) Sewage and storm drainage facilities-pumping stations and treatment plants
(22) Veterinary clinics
(Ord. 208; Code 2021)
(a) The consumer’s premises shall be open at all reasonable times to the city or its authorized representative, for the conduction of surveys and investigations of water use practices within the consumer’s premises to determine whether there are actual or potential cross connections in the consumer’s water system.
(b) On request by the city or its authorized representative, the consumer shall furnish requested information on water use practices within his premises and in the consumer’s water system.
(c) On request by the city or its authorized representative, the consumer shall conduct periodic surveys of water use practices on the premises of the consumer’s water system to determine whether there are actual or potential cross connections. The consumer shall provide the survey results to the city or its authorized representative.
