The City of League City uses a third party, Backflow Solutions Inc., to maintain electronic records of backflow testing information. Backflow test reports and tester licensing and gauge information are entered by testers or testing company representatives online via the internet in the BSI database. BSI sends testing due and over-due notices to customers with the last tester of record listed on the letter as a convenience. Testing is due on the same date every month and not a year from the last test date.

Contact BSI by phone at 800-414-4990, email BSI, or mail it to:
