The purposes of this chapter are as follows:
A. Protection Of Water Supply: To protect the Public drinking water supply of LaVerkin City from the possibility of contamination or pollution by requiring compliance with the Utah Public Drinking Water Rules (UPDWR) and the Plumbing Code, as adopted by the State of Utah, require a cross connection control protection of all public drinking water systems in the State of Utah. Compliance with these minimum safety codes will be considered reasonable diligence for the prevention of contaminants or pollutants which could backflow into the public drinking water system; and,
B. Elimination Or Control Of Cross Connections: To promote the reasonable elimination or control of cross connections in the plumbing fixtures and industrial piping system(s) of the consumer, as required by the state regulations and plumbing code to assure water system safety; and,
C. Administration Of Backflow Prevention: To provide for the administration of a continuing program of backflow prevention which will systematically and effectively prevent the contamination or pollution of all drinking water systems. (Ord. 91-01, 2-6-1991; amd. Ord. 2020-06, 12-16-2020)
As used in this chapter, the following terms shall have the meanings specified, unless a different meaning is clearly evident from the context:

AUXILIARY WATER SUPPLY: | Any water supply on or available to the premises other than the purveyor's public water supply will be considered as an auxiliary water supply. These auxiliary waters may include water from another purveyor's public potable water supply or any natural source such as a well, spring, river, stream, harbor, etc., or "used waters" or "industrial fluids". These waters may be contaminated or polluted or they may be objectionable and constitute an unacceptable water source over which the public works director does not have authority for sanitary control. |
BACKPRESSURE: | The phenomenon that occurs when the customer's pressure is higher than the supply pressure. This could be caused by an unprotected cross connection between a drinking water supply and a pressurized irrigation connection, a boiler, a pressurized industrial process, elevation differences, air or steam pressure, use of booster pumps or any other source of pressure. |
BACK SIPHONAGE: | The flow of water or other liquids, mixtures or substances into the distribution pipes of a potable water supply system from any source other than the intended source, caused by the reduction of pressure in the potable water supply system. |
BACKFLOW: | The undesirable reversal of flow of water or mixtures of water and other liquids, gases, or other substances into the distribution pipes of the potable water supply from any source. |
CERTIFIED BACKFLOW TECHNICIAN: | An individual that has successfully completed a Division of Drinking Water approved backflow certification course with a written and practical examination, and has maintained this certification in accordance with R309-305, Certification Rules for Backflow Technicians. |
CONSUMER/ CUSTOMER: | The owner or operator of a privately or publicly owned plumbing system(s) having a service connection from the public drinking water system. |
CONTAINMENT (METER OR POINT OF CONNECTION PROTECTION): | The practice of installing approved backflow prevention assemblies/devices at the service connection of consumers in order to protect the public drinking water system from any backflow from the consumers plumbing system. |
CONTAMINATE: | Any substance introduced into the public drinking water system which creates a threat to the public health such as poisoning, pathogenic organisms or any other public health concern. |
CROSS CONNECTION: | Any physical connection or arrangement of piping or fixtures which may allow nonportable water or industrial fluids or other material of questionable quality to come in contact with potable water inside a distribution system. This would include any temporary connections, such as swing connections, removable sections, four-way plug valves, spools, dummy sections of pipe, swivel or changeover devices or sliding multipart tubes or other plumbing arrangements. |
CROSS CONNECTION, CONTAINMENT: | The installation of an approved backflow assembly at the water service connection to any customer's premises where it is physically and economically infeasible to find and permanently eliminate or control all actual or potential cross connections within the customer's water system; or, it shall mean the installation of an approved backflow prevention assembly on the service line leading to and supplying a portion of a customer's water system where there are actual or potential cross connections which cannot be effectively eliminated or controlled at the point of the cross connection (isolation). |
CROSS CONNECTION, CONTROLLED: | A connection between a potable water system and a nonportable water system with an approved backflow prevention assembly properly installed and maintained so that it will continuously afford the protection commensurate with the degree of hazard. |
DEGREE OF HAZARD: | Either a pollutant (non-health) or contaminate (health) hazard that may be introduced into the public drinking water system through a cross connection. Through an evaluation of the consumers plumbing system, the threat to 6 public health (the degree of hazard) will be determined. In the past these terms have been referred to as high hazard for health and low hazard for non-health. |
ISOLATION (PLUMBING CODE COMPLIANCE): | The practice of installing approved backflow prevention assemblies/devices at each point of cross connection or system outlet as required by Plumbing Code as adopted by the State and its amendments. |
POLLUTANT: | Any substance introduced into the public drinking water system which does not create a threat to the public health, but which does adversely and unreasonably affect the aesthetic quality of the water. |
PUBLIC DRINKING WATER SYSTEM: | A water system that is either publicly or privately owned, that provides water for human consumption and other domestic uses, which: has at least fifteen (15) service connections, and/or serves an average of at least twenty-five (25) individuals at least sixty (60) days out of the year. |
SERVICE CONNECTION: | The terminal end of the public drinking water system where the water purveyor transfers jurisdiction and sanitary control of the water. If a water meter is present, then the service connection exists at the downstream end of the meter. |
WATER PURVEYOR: | The public or private owner or responsible party of a public drinking water system. (Ord. 91-01, 2-6-1991; amd. 1998 Code; Ord. 2020-06, 12-16-2020) |
