Cross-Connection Control Program

Get more information:

    The Water and Sewer Department has a Cross-Connection Control Program. We are committed to keeping your water safe and free from pollutants and harmful substances that could affect your health. Our program focuses primarily on containment and prevention.

    A cross-connection is any connection to the drinking water system that could introduce pesticides, fertilizers, used water, fluids, gases, or anything else into the water distribution system. Normally, water flows out of the distribution system under pressure. When a cross-connection exists, a drop in water pressure can cause a reversal of flow, allowing harmful substances to enter the public water system.

    Common residential sources of cross-connection contamination include: irrigation systems, fertilizer injection systems, hoses connected to chemical spray bottles; chemicals in water beds, hot tubs, swimming pools, water features, aquariums, fountains, in-home water treatment systems, solar heating systems, and swamp coolers. Commercial and industrial sites also have the potential for cross connections. Cooling systems, boilers, solvents and chemicals used in manufacturing processes, liquid storage tanks, waste disposal systems, fire sprinkler systems, including applicable residential sources previously listed, also present potential hazards.

    Below are some ways that you can keep the water system safe.

    • Install backflow prevention assemblies to prevent potential cross-connections, and have a certified backflow tester inspect and test your assemblies once a year to ensure they work properly. Click here to get a list of certified backflow testers in the area.

    • If you suspect you may have a cross-connection, contact a qualified plumber who is familiar with cross-connections, hydraulics, and pollution factors.

    • Be observant. Check for potential sources of cross-connections around your home, business, or industrial site.

    • Never leave hoses in buckets, pools, or sinks.

    • A backflow prevention assembly is necessary for all irrigation systems. A copy of a certified backflow tester's report is required to obtain final approval for a sprinkler system permit.

    • All commercial and industrial customers must install backflow prevention assemblies on their water service lines, fire sprinkler systems, and irrigation systems. In the past few years, commercial and industrial sites in Greeley were surveyed to identify potential cross-connections. Each site's water service system was inspected for potential hazards.
    • Residential customers should have backflow prevention assemblies on fire sprinkler systems and irrigation systems.
