Current through Register Vol. XLI, No. 50, December 13, 2024
Section 64-15-3 - Definitions
3.1. Air Gap Separation. -- A physical separation between the free-flowing discharge end of a water supply pipe and the flood level rim of a vessel open to the atmosphere having a minimum unobstructed vertical distance between the supply pipe equal to twice its inside diameter or one inch, whichever is greater.
3.2. Approved. -- Accepted by the Commissioner as being suitable for the proposed use.
3.3. Approved Backflow Prevention Assembly. -- A double check valve assembly, reduced pressure backflow prevention assembly, other devices or methods approved by the Commissioner for preventing backflow.
3.4. Auxiliary Water Supply. -- Any water source or system available within the building or premises other than the community public water system including, but not limited to, individual wells, springs, and cisterns. A private water storage tank supplied by a community public water system is considered an auxiliary water supply unless its design meets the most current minimum design standards required for storage tanks for community public water systems, and the water contained in them is potable.
3.5. Backflow. -- The flow of water or other liquids, mixtures, or substances into the distributing pipes of a potable supply of water from any source or sources other than its intended source. Backsiphonage is one type of backflow.
3.6. Commissioner. -- The Commissioner of the Bureau for Public Health or his or her designee.
3.7. Cross-Connection. -- Any physical connection or arrangement between two otherwise separate systems or sources, one of which contains potable water and the other either water, steam, gas, or chemical of unknown or questionable safety whereby there may be a flow from one system or source to the other, the direction of flow depending on the pressure differential between the two systems.
3.8. Degree of Hazard. -- The potential risk to health and potential adverse effects upon the public water system based on the probability of backflow occurring and the type or nature of the contaminant.
3.9. Double Check Valve Assembly. -- An arrangement or device consisting of two single, independently acting watertight check valves with connections for testing the water-tightness of each check valve.
3.10. Flood Level Rim. -- The edge of the vessel or receptacle from which water overflows.
3.11. Health Hazard. -- Any condition, device, or practice that in the judgment of the Commissioner creates or may create a danger to the health and well-being of the water customer.
3.12. Interchangeable Connection. -- An arrangement or device that allows the alternate but not simultaneous use of two sources of water.
3.13. Low-Suction Pressure Cut-Off Controller. -- An arrangement or device designed to shut off a pump when the pressure at the suction side of the pump falls below a specified level.
3.14. Person. -- An individual, partnership, association, syndicate, company, firm, trust, corporation, government corporation, institution, department, division, bureau, agency, or any entity recognized by law.
3.15. Potable Water. -- Water free from impurities in amounts sufficient to cause disease or harmful physiological effects, with bacteriological, chemical, physical, and radiological quality conforming to applicable regulations and standards of the bureau for public health.
3.16. Public Water System (PWS). -- Any water supply or system that regularly supplies or offers to supply water for human consumption through pipes or other constructed conveyances, if serving at least an average of 25 individuals per day for at least 60 days per year, or which has at least 15 service connections, and shall include:
(1) Any collection, treatment, storage, and distribution facilities under the control of the owner or operator of the system that are used primarily in connection with the system; and
(2) Any collection or pretreatment storage facilities not under the control of the owner or operator of the PWS that are used primarily in connection with the system. A PWS does not include a system that meets all of the following conditions:
(1) Consists only of distribution and storage facilities and does not have any collection and treatment facilities;
(2) Obtains all of its water from, but is not owned or operated by, a PWS that otherwise meets the definition;
(3) Does not sell water to any person; and
(4) Is not a carrier conveying passengers in interstate commerce.
3.17. Reduced Pressure Backflow Prevention Assembly. -- A device containing a minimum of two independently acting check valves, an automatically operated pressure differential relief valve located between the two check valves and watertight valves located at each end of the assembly, with connections for testing the operation of the device.
3.18. Severe Health Hazard. -- A hazard to the health of the user that could reasonably be expected to result in significant morbidity or death.
3.19. Unprotected Cross-Connection -- Any cross-connection with no approved backflow prevention assembly, air gap separation, double check valve assembly, or reduced pressure backflow prevention assembly installed.
3.20. Water Customer. -- The owner or person in charge of any building or premises supplied by or in any manner connected to a community public water system.
3.21. Water Service Line. -- A pipe or water line, with or without a meter and valves, through which the water customer conveys the water from the public water system to the initial point of use.
