Local answer

What to check for Aurora

Aurora does not publish a separate irrigation mini-program as strongly as Denver does, but the annual testing and protected-service rules still apply to landscape risk when an assembly is required.

  • Due basis: Aurora says operational tests by a certified technician must be conducted upon installation and at least annually thereafter, and results must be submitted online before the annual test due date.
  • Who is affected: Aurora Water customers and property owners whose service requires a backflow prevention assembly, including hydrant users who need RP protection.
  • Program phone: 303-326-8520

Signals that matter before you act

  • Annual test discipline still applies once an irrigation-related assembly is required.
  • Landscape and outdoor water uses can surface cross-connection risks even when the page is not branded as an irrigation program.
  • Hydrant-related outdoor water use explicitly requires RP protection.
Workflow

Aurora workflow order

  1. Confirm whether the irrigation or temporary outdoor use requires city-recognized backflow protection.
  2. Use the correct RP or other required assembly for the setup.
  3. Keep the online annual test submission current once the device is active.
