Greenville Water: backflow test rules

  • Who must test. Most commercial, industrial, irrigation (as noted) and private fire protection customers are required to install, maintain and test a backflow prevention assembly. Source.
  • Notices and deadlines. Greenville Water mails the initial test notice 45 days before the device test due date, and allows a 15-day grace period after the due date. Source.
  • How the report is filed. All certified backflow testers must upload test results through Greenville Water's Backflow Test Result Portal (backflow.greenvillewater.com). Source.
  • Tester registration. Testers new to Greenville Water must email a picture of their certification to bfp@greenvillewater.com; portal registration requires a valid SCDHEC certificate. Source.
  • If a test is missed. A test 15 days late draws a $500 non-compliance fee, and Greenville Water hires a third party to test the device. Source.
