Water Administrative Assistant
The City of Kingman's Backflow Prevention Program is a containment program as defined by state regulation, R18-4-232. This program has an employee assigned to administer the Backflow Prevention Program.
The purpose of installing a backflow prevention device is to protect the public water supply of the City of Kingman from the possibility of contamination or pollution. A backflow prevention device provides isolation within the user's system from contaminants or pollutants that could backflow into the public water supply. The Backflow Prevention Program provides for the monitoring and enforcement of a continuing program of backflow prevention.
Article X, Cross-Connection Control Policy And Procedures
Section 1 : Administration of Program
Arizona's drinking water rules were substantially revised with new rules adopted on August 8, 1991. Some significant changes include new requirements for backflow prevention. These rules were passed and adopted by the mayor and the common council of the City of Kingman, Arizona, on the 20th day of June 1994.
The City of Kingman's Cross-Connection Control program was established to ensure the quality of the public water supply. The City of Kingman Water Department (hereinafter called the "Department") has the responsibility to provide safe drinking water to the public, and also to protect it from the reversal of any pollutants or contaminants due to backflow or back siphonage. The Department's program will be limited to system protection (containment) with all internal protection (isolation) problems being handled by the local health agency.
The Department is vested with the authority and responsibility for implementation of an effective Cross-Connection Control program. The specialist is responsible for several aspects of the program. The specialist will be able to conduct surveys to determine the degree of hazard on the premises, record keeping (records shall be kept for three years), review by DEQ or other delegated agency inspectors, and notification of required installation and annual testing.
Section 2 : Auxiliary Water Systems
The term "auxiliary water supply" shall mean any water supply on or available to the premises other than the water purveyor's approved public potable 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. They may be polluted or contaminated or they may be objectionable and constitute an unacceptable water source over which the water purveyor does not have sanitary control.
Section 3 : Certified Testers
The City of Kingman will maintain a list of certified backflow prevention assemblies testers. Backflow assemblies will be tested and repaired by persons who have demonstrated their competency in testing these such assemblies and can properly test any type of assembly. The customer who is responsible for installing, maintaining and testing the assembly should be given the opportunity to select from a number of certified testers.

Section 4 : Change of Occupancy or Use
After a thorough survey of the water system has been conducted, it is necessary to keep up with the changes that may affect the safety of the water system. One method used to keep up with these changes is to re-survey, another is to use the building department and the customer service section. The specialist should be notified of any noticeable changes to billing due to water usage.
Section 5 : Combined Services
There are occasions when the customer requests that the meter be set so that the internal piping can be used to provide both domestic water and either industrial or fire sprinkler water. The water purveyor determines the type of backflow protection required on a case-by-case basis after a complete inspection of the property by the specialist.
Section 6 : Critical Services
Critical services are water services that cannot be shut off, even for a few moments, at any time. When such a water use condition is made known by the consumer, the Department will recommend that two services be established to the property. In such case, the same level of protection would be required for each service.
Section 7 : Dual Services
Dual services is a condition whereby two or more services supply water to one property. (Example: One meter is installed for domestic use and the other for irrigation.) The level of protection is to be determined by the specialist. An (AVB) Atmospheric Vacuum Breaker installed properly is minimum protection for any irrigation system.
Section 8 : Existing Assemblies
A specialist may deal with existing assemblies in one of two ways:
- If these Backflow Prevention Assemblies ("BPA"s) (approved by the Foundation for Cross-Connection Control and Hydraulic Research) are approved, then they are left in service and notation of make, model and serial number are entered into the agency's records.
- If the assembly is no longer approved, but was an approved assembly by the water purveyor at the time of installation, then the assembly will remain in service as long as it continues to function properly, with the period of testing reduced. If the assembly was never an approved assembly then it should be removed and replaced with an approved assembly.
Section 9 : Fire Sprinkler Systems
Class 1 and Class 2, fire sprinkler systems, constructed of non potable material prior to August 8, 1991, shall be given the option to retrofit with an appropriate BPA, or to have the single check valve or alarm check valve inspected at least quarterly by way of a Flow and Valve Confidence Test. Results will be provided to the water purveyor and the local fire marshal within 30 days. Any fire sprinkler system which fails two consecutive quarterly inspections shall be re-engineered with an appropriate BPA. The City fire chief or appointed person shall be responsible for the installation and inspection of all private fire lines and fire sprinkler systems, including BPAs, new installations and retrofits. The Department shall be responsible for the annual testing and recordkeeping of said assemblies.
Class 3 - Class 6 fire systems will require backflow protection.
Section 10 : High and Low Water Pressure Systems
Code specifies that the minimum distribution pressure at the point of delivery shall be 40 psi (pounds per square inch). If the distribution pressure is low, but still above this minimum level, the water purveyor may recommend that the customer installs a booster pump within the property to adequately serve all their needs. If the customer does install a booster pump, it will also be required as minimum protection that an approved double check assembly be installed, so that backpressure water from the customer's property cannot be induced into the water agency system.
Section 11 : Irrigation Systems
Irrigation systems are not limited to commercial irrigation. Any water usage of this water agency for irrigation will be protected by a backflow device. An AVB, properly installed, (6" above any downstream piping or outlets), is minimum protection for any irrigation system. A PVB will be installed 12" above any downstream piping and outlets if under backpressure. When it is not practical to install a PVB, or where chemigation is used, an RP assembly will be installed with a 12" minimum ground clearance and a height not to exceed 36 inches.
Section 12 : Non-Compliance
The water department has the right to refuse service or terminate water service whenever inspection of the premises shows that a required backflow prevention assembly has either not been installed properly or, if installed, has not been tested and/or maintained as required.
Section 13 : Restricted or Classified Services
Whenever a legal representative of the water agency is refused admission to a property for the purpose of inspecting it for actual or potential cross-connections, the water agency may take one of two lines of action:
- refuse to serve water to the property
- require maximum backflow protection at the meter
Section 14 : Solar Heating Systems
Solar heating systems may be roughly grouped as follows -
- There is no need for backflow prevention devices for once-through systems for heating domestic water only (as a pre-heater for domestic hot water heater).
- If the weep hole or vent is easily visible, there may be no need for backflow protection for a double-walled heat exchanger system with fluid in the solar side of the system, providing it is totally separated from the domestic hot water by an air space that is vented to the atmosphere. The specialist will inspect and determine if there is cause for an assembly.
- Any system having a single-walled heat exchanger is suspect and usually requires a reduced pressure principal backflow assembly on the domestic hot water line to this unit. The reason that a single-walled heat exchanger is suspect is because chemicals may be added as a corrosion inhibitor or anti-freeze may be added for freeze protection.
Section 15 : Sump & Lift Stations
Whenever a property is located so that the drainage water or the sanitary discharge must be caught in a sump and pumped up to the storm drain or the sanitary sewer, the water supply to that property must contain an approved reduced pressure principal assembly.
Assemblies must be installed by a licensed contractor.
Standard detail installation requirements can be obtained from George Sedich at the Public Works Facility, 3700 E. Andy Devine, Kingman, AZ 86401, (928)692-3121.
Do not forget to protect your assembly from freezing!. Your installer or tester can help you with the proper protection.
