Hydro Designs to Manage Cross Connection Control Program

The Algoma Utilities water system delivers safe, high-quality drinking water every day. To continue to protect the public health and keep the water system safe from contaminants and pollutants we are required by the Wisconsin Department of Natural Resources (DNR), Wisconsin Department of Safety and Professional Services (DSPS), and the City of Algoma Municipal Code to maintain a Cross Connection Control Program.

The Algoma Utilities has contracted with Hydro Designs, Inc. (HDI), of New Berlin, Wisconsin to manage our program. HDI is a firm that specializes in backflow prevention education and cross connection control inspections. They currently manage program services for over 115 municipalities and water utilities in Michigan, Wisconsin, and Florida. HDI will perform inspections of commercial, industrial, and residential facilities throughout the city to detect actual and potential cross connections, and make recommendations for the installation of backflow prevention devices or assemblies where necessary. This will help ensure that contaminated or polluted water cannot backflow into clean drinking water. Buildings that have Well Water supply only and have no municipal water supply connection will not require an inspection.

What Is a Cross Connection?

A cross connection is a direct or potential connection between any part of the public water supply system and a source of contamination or pollution. The most common form of cross connection is a garden hose, which is easily connected to the public water supply system and can be used to apply a variety of potentially dangerous substances, including chemicals and fertilizer. Other common cross connections include dishwashers, toilets, pressure washers, boilers, pools, and lawn sprinkler systems.

What is a Cross Connection Survey?

The cross connection survey is the first step in our program. NR 810.15 requires that all residential, industrial and commercial facilities be surveyed for cross connections regularly. A survey is a walk-through of the water-system piping in a building or property, starting at the water meter and ending at the last free-flowing tap. At the end of the survey HDI will produce a report describing any violations or discrepancies found, as well as a time frame for compliance. Inspection notices will be mailed to water customers approximately two weeks before the scheduled inspection date. You, as the customer, should be available during the inspection to answer questions and provide access.

If you are an Algoma Utilities water customer, you may soon be receiving information regarding this program. Please contact HDI at 1-800-315-4305 with questions regarding the cross connection control program and/or inspections. If you have any questions regarding the validity of the inspection, please contact Algoma Utilities at 487-5556.
