Backflow Prevention Program

  • The City operates a state-mandated Backflow Prevention Program to prevent drinking water contamination. 

    Backflow is a health issue when drinking water is connected directly to a non-drinking water source. This is commonly called a cross connection.  

    Cross connection sources  

    • Lawn sprinkler systems
    • Swimming pools, hot tubs and spas
    • Cooling and heating systems
    • Portable pressure washers
    • Sprayer hose attachments
    • Garden hoses
    • Radiator flush kits
    • Fire sprinklers
    • Utility sinks
    • Solar systems

    City requirements 

    Without a required valve installed to prevent backflows, contaminants could taint drinking water.

    • Backflow assemblies must be installed on all water-using systems and equipment.
    • Each assembly is required to be tested first upon installation, then once a year.
