All industrial and commercial customers are required by ordinance to install and maintain backflow prevention assemblies at every water service connection to Charlotte Water. This includes domestic, irrigation, fire line services, and swimming pool meters.
Before beginning any construction project, industrial and commercial customers must submit construction plans to Mecklenburg County Land Use and Environmental Services. There, Charlotte Water will evaluate your plans and inform you of the requirements for a backflow device.
When the backflow prevention assembly is installed, call Charlotte Water Backflow at 704-336-2456 to request an inspection. A Charlotte Water approved and certified tester must test the device upon installation and annually thereafter.
