Aspen utility backflow testing requirements

• Aspen uses BSI for notification and tester reporting.
• The city publishes a certified tester list rather than leaving customers to guess.
• The public guidance separates irrigation and fire-system device expectations.
• Initial notifications now come directly from BSI.
• Backflow testers are required to submit reports through the BSI portal.
• Residents still choose their preferred certified tester from the city's list.

• Aspen explicitly mentions residential lawn sprinkler systems as an isolation-device example.
• Residential users are not outside the system if they have irrigation or another protected cross-connection risk.

• Commercial and multi-family accounts have been in Aspen's containment program for years and sit on a clear annual cadence.
• The BSI workflow makes Aspen operationally stronger than a generic city explainer page.

Aspen publicly calls out irrigation systems as common cross-connections and says irrigation systems generally require a vacuum breaker.

• The city lists irrigation systems among common cross-connection examples.
• Aspen's public guidance says irrigation systems generally use a vacuum breaker.
• Residential lawn sprinkler systems are a specific example of an isolation device.

Aspen specifically calls out fire systems and says fire systems generally use a double check backflow preventer.

• Aspen includes fire systems in its common cross-connection examples.
• The city guidance says fire systems generally use a double check backflow preventer.
• Aspen's tester list separates domestic-and-irrigation capability from fire-capable testers.

Testing is market-priced, but Aspen's certified-list and BSI workflow shape the real customer path.

Repair and retest cost depends on whether the assembly is domestic, irrigation, or fire-related.

Aspen's strongest commercial signal is the utility's operational discipline around reminders, list-based routing, and BSI reporting.
