Backflow Prevention. Preventing backflow is a matter of avoiding the reverse flow of unwanted substances into the drinking water by using special plumbing devices and practices. Preventing backflow is accomplished by requiring physical plumbing methods (air-gaps) or requiring the installation of mechanical devices (backflow prevention assemblies or devices) designed specifically to prevent backflow within certain customer premises. Fairfax Water hydrant meters are supplied with dual check valves (3” meters) and vacuum breakers (5/8” meters) to help protect against cross-connections and backflow events. If a hydrant meter is being used to fill a tank or container, further protection is needed by utilizing an air-gap separation between the hose and whatever is being filled. The air-gap must be a separation of two times the size of the inside diameter of the water supply pipe between the pipe outlet and the flood rim level of the tank, container, and/or basin with a minimum of 6 inches. A hose must never be submerged into the water while filling a tank, container, or pool. Any equipment such as tank trucks and/or portable water tanks that are filled using the hydrant meter shall be properly equipped to prevent contamination of the water system from backflow or backsiphonage. The use of any hydrant meter in a manner that jeopardizes the Fairfax Water supply and violates the Fairfax Water Cross-Connection Control and Backflow Prevention Program Manual shall be grounds for immediate confiscation of the meter and potential charges and/or prosecution.

Backflow Prevention. If the requested tap is to serve commercial property, an approved, properly installed, backflow prevention assembly must be installed on each potable line serving the property (see specification information). If the requested tap is to serve an existing house or building, Missoula Water must inspect the property to determine if a private well or other auxiliary water supply is located on the property. Missoula Water must also perform an inspection if the tap is to serve a property, either new or existing, on which a private well or auxiliary water supply is planned to be installed. If there is to be a private well or other source of water in addition to the Missoula Water potable supply, state law requires either an approved backflow prevention assembly be installed on each Missoula Water potable line serving the property or the private well or auxiliary water supply be abandoned per DNRC specifications. Contact Missoula Water (552-6756) for specifics on the proper assembly to be installed and the installation specifications. The contractor is responsible for providing a job site that meets all local, state, and federal laws, statutes and regulations and must also perform work in accordance with Missoula Water’s specifications. Missoula Water’s specifications require that the service line be 6 feet deep with trace wire. The curb box must be installed and ready for review for adherence to Missoula Water specifications. The service line and main must be bedded properly. A safe work site is required and each contractor must provide a properly sloped trench or a trench box with adequate room in the trench box to properly complete the tap. Any tap larger than two inches will require the contractor to provide the appropriate equipment and an operator to assist Missoula Water personnel in lowering tapping equipment into the trench. If such equipment is not provided, Missoula Water has the authority to deny the tap being performed. Properly designed, installed and maintained traffic control will be provided by the excavator and the traffic control plan will be approved by the City of Missoula or applicable party. While Missoula Water personnel are on the job site, no equipment will be operated in the vicinity of the tap and the contractor and their employees will not enter any unsafe trench (See tap site requirements). These specific requirements do not relieve the contractor from following all other laws, regulations or statutes not specifically mentioned. When m...
