CHAPTER 15. UTILITIESCHAPTER 15. UTILITIES\Article 2. Cross-Connection Control

(a)   Purpose: This article is necessary:

(1)   To protect the public potable water supply of the City from pollution or contamination due to cross-connection;

(2)   To prohibit and eliminate uncontrolled cross-connections within the potable water supply system;

(3)   To provide for the establishment of a cross-connection control program; and,

(4)   To comply with Kansas Administrative Regulation (K.A.R.) 28-15-18(h).

(b)   Scope: All potable water distributed by the City Utilities Department, whether to public or private users, and whether supplied directly or indirectly, is regulated by the cross-connection control program, as established under this article and the regulations adopted under the authority set out in Section 15-211 hereof.

(c)   Intent:

(1)   Through this article, it is the intent of the City to recognize the varying degrees of hazard and to apply the principle that the degree of protection be commensurate with the degree of hazard, in accordance with Kansas Department of Health and Environment criteria.

(2)   Provisions of this article are intended to supplement, not supersede or replace, provisions of the Uniform Plumbing Code, as adopted by the City.

(Code 1961, 9-15-1; Code 2023)

(a)   The City Manager will maintain primary responsibility for the development, implementation, and enforcement of the cross-connection control program. All City utility departments and personnel shall cooperate as necessary, to fulfill the objectives of this program.

(b)   Customers/Consumers:

(1)   The customer has the primary responsibility of preventing pollutants and contaminants from entering a private potable water system or the public potable water system.

(2)   The customer, at no expense to the City, shall install, operate, test, maintain, and repair approved backflow prevention devices as directed by the City Manager and shall maintain accurate records for all such devices, as required by this article.

FREE WATER SURFACE: A water surface at atmospheric pressure.

FLOOD LEVEL RIM: The edge of the receptacle from which water overflows.

HAZARDOUS CONDITIONS: Actual or potential threat of a physical or toxic nature to the public water supply that would be a danger to the health of the consumer.

HEALTH HAZARD: Any condition, device or practice in the public water supply system which would or could create a danger to the health and wellbeing of anyone using the water or would or could allow contamination of the water.

KDHE: Kansas Department of Health and Environment.

PLUMBING: The practices, materials and fixtures used in the installation, maintenance, extension and alteration of all piping, fixtures, appliances and appurtenances.

POLLUTION: The presence of any foreign substance (organic, inorganic, radiological 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 the public health but which does adversely affect the water.

PRESSURE VACUUM BREAKER (PVB): A mechanical device used to prevent backflow due to backsiphonage. A PVB may be used under continuous line pressure.

PUBLIC WATER SUPPLY SYSTEM: The public water system and the consumer’s water system.

To be approved, these assemblies must be readily accessible for inspection and testing and be installed in an aboveground location where no part of the assembly will be submerged.

SERVICE CONNECTION: The terminal end of the service line from the public water system. If a meter is installed at the end of the service, then the service connection means the downstream end of the meter.

TESTER: A trained technician certified in the testing and repair of backflow prevention devices. See “approved technician”.

VACUUM: Any absolute pressure less than that exerted by the atmosphere.

VACUUM BREAKER: A device that permits entrance of air into the water supply distribution line to prevent backsiphonage.
