The purpose of this article is to protect the public water supply of the City of Louisburg from contamination due to backflow or backsiphonage from any cross connection; and to prohibit and eliminate all cross connections to the public water supply; and to provide for the maintenance of a continuing effective cross connection control program. This program shall include regularly scheduled inspections to detect and eliminate current cross connections and to prevent future cross connections.
No person, company, corporation, or institution shall establish or permit to be established or maintained, any cross connection whereby a private water supply or any source of contamination may enter the regular public water supply of the City of Louisburg, unless said source is approved by the city council of the City of Louisburg, and the Kansas Department of Health and Environment.
(a) The presence of any foreign substance (organic, inorganic or biological) in water which tends to degrade its quality so as to constitute a hazard or impair the usefulness or quality of the water to a degree which does not create an actual hazard to tile public health but which does adversely affect the water.
(b) Reduced Pressure Zone Backflow Preventer. An assembly of two independently acting soft seated approved check valves together with a hydraulically operating mechanically independent differential pressure relief valve located between the check valves and at the same time below the first check valve. The unit shall contain properly located test cocks and resilient seated shut-off valves at each end of the assembly. To be approved these assemblies must be accessible for inspection and testing and be installed in an above ground location where no part of the assembly will be submerged.
(c) Tester. A trained technician certified in the testing and repair of backflow preventers.
(d) Vacuum. Any absolute pressure less than that exerted by the atmosphere.
(e) Vacuum Breaker. A device that permits entrance of air into the water supply distribution line to prevent backsiphonage.
(f) Water, Potable. Water free from impurities in amounts sufficient to cause disease or harmful physiological effects. Its quality shall conform to Kansas Department of Health and Environment requirements for public water supplies.
(g) Water, Non potable. Water that is not safe for human consumption or that is of questionable potability.
(a) Connections to Boilers. Potable water connections to boiler feed water systems in which boiler water conditioning chemicals are or can be introduced shall be made through an air gap or through a reduced pressure zone principle Backflow Preventer located in the potable water line before the point where such chemicals may be introduced.
(b) Some prohibited connections. Connection to the Public Potable water supply system for the following is prohibited unless properly protected by the appropriate backflow prevention device.
(2) Operating, dissection embalming, and mortuary tables or similar equipment – in such installations the hose used for water supply shall terminate at least 12 inches away from every point of the table or attachments.
(3) Pumps for non-potable substances. Priming only through an air gap,
(4) Building drains, sewers or vent systems.
(5) Commercial buildings or industrial plants manufacturing or otherwise using polluting or contamination substances,
(6) Any fixture of similar hazard.
(c) Refrigeration Unit Condensers and Cooling Jackets except when potable water provided for a refrigeration condenser or cooling jacket is entirely outside the piping or tank containing a toxic refrigerant, the inlet connection shall be provided with an approved Backflow Preventer. Heat exchangers used to heat water for potable use shall be of the double wall type.
(d) Approved Devices Required. The type of protective device required under this article shall be determined by the degree of hazard which exists as follows:
(1) Premises having auxiliary water supply shall protect the public system by either an approved air gap or an approved reduced pressure principle backflow prevention assembly.
(2) Premises having water or substances which would be non-hazardous to the health and well-being of the consumers shall protect the public system with no less than an approved double check valve assembly. Premises where material dangerous to health is handled in a manner which creates an actual or potential hazard shall protect the public system by an approved air gap or an approved reduced pressure principle backflow prevention assembly.
(3) Premises where cross connections are uncontrolled shall protect the public water supply by installing an approved air gap or an approved reduced pressure principal backflow prevention device at the service connection.
(4) Premises where because of security requirements or other prohibitions it is impossible to complete an in-plant cross connection inspection, the public system shall be protected by an approved air gap or an approved reduced pressure principle backflow prevention assembly.
Premises which may fall into one or more of the above mentioned categories may be, but are not limited to the following:
(A) Beverage bottling plants
(B) Buildings - Hotels, Apartments, Public or private buildings, or other structures having actual or potential cross connections
(C) Car wash facilities
(D) Chemical manufacturing, handling, or processing plants
(E) Chemically contaminated water
(F) Dairies and cold storage facilities
(G) Film or photography processing laboratory
(H) Fire systems
(I) Hospitals, Medical Centers, Morgues, Mortuaries, Autopsy facilities, Clinics, or Nursing and Convalescent homes
(J) Irrigation Systems Laundries
(L) Metal Cleaning, processing, or fabricating plants
(M) Oil and gas production, storage, or transmission facilities
(N) Packing or food processing plants
(O) Paper and paper products plants
(P) Power Plants
(Q) Radioactive materials plants or handling facilities
(R) Restricted or classified facilities
(S) Rubber plants
Approved devices to protect against backflow of backsiphonage shall be installed at all fixtures and equipment where back- flow or backsiphonage may occur and where there is a hazard of contamination of the potable water supply system.
The Public Works Director or other designate of the city council of the City of Louisburg shall have the right of entry into any building or premises in the city or within the area serviced by the city water supply, as frequently as necessary in order to ensure that plumbing has been installed in a manner as to prevent the possibility of contamination of the public water supply of the City of Louisburg, Kansas.
Pursuant to the authority given under Home Rule Powers and K.S.A. 63-163a, the City of Louisburg, may refuse to deliver water to any premises where a condition exists which might lead to the contamination of the public water and may continue to refuse to deliver water until the condition is corrected to the satisfaction of the city. In addition, the city may immediately terminate water service to a premise where a back- flow or backsiphonage condition exists which may be hazardous to the health of customers served by this public water supply system of the City of Louisburg.
There is hereby incorporated by reference for the purpose of regulating cross connection between the public water supply and any sources of contamination that certain manual adopted by the Governing Body of the City of Louisburg known as “MANUAL OF REGULATIONS REGULATING BACKFLOW AND BACK-SIPHONAGE OF CONTAMINANTS DUE TO CROSS CONNECTION FOR THE CITY OF LOUISBURG PUBLIC WATER SUPPLY.” No fewer than three copies of said manual shall by marked or stamped, “Official Copy as Adopted by Ordinance No. 479,” and to which shall be attached a copy of said ordinance, and filed with the city clerk to be open to inspection and available to the public at all reasonable hours.
