The Michigan Department of Environment, Great Lakes, & Energy in conjunction with the Village of Empire Ordinance No. 113, requires that all public water suppliers have a Cross Connection Control Program that tests all backflow prevention devices on a yearly basis by a certified plumber. Common types of testable backflow prevention devices include, but not limited to:

  • Lawn/greenhouse irrigation systems
  • Fire Suppression Systems
  • Chemical/fertilizer injection pumps
  • Boiler Systems

Any plumber certified to do this inspection must hold a current ASSE 5110 license.
