A method of tracking backflow assemblies is provided. The method comprises the steps of receiving backflow assembly data for water customers associated with a water supply system, generating a database based on the backflow assembly data, transmitting test reminder notifications to testers associated with the water customers, receiving test result data from the testers, updating the database based on the test result data, and transmitting the test result data to municipal administrators. The backflow assembly data includes water customer information, backflow assembly information and backflow test history information. The database is stored within a storage device. The testers are notified based at least partially on the backflow assembly data. The updated database is stored within the storage device.
