Where do I submit backflow test reports?

The city of Thornton uses Backflow Solutions, Inc. for tracking all backflow test reports.

Brand new never existing installs can be emailed to BSIonline@backflow.com and first test will be submitted with BSI's current fees. Beyond that each individual test report submitted will be charged at BSI’s most current price.
