The Cross Connection Control program oversees annual testing of devices to prevent backflow into the potable water system.
For Customers: The City issues letters to notify customers when tests are due. Customers are then responsible for making arrangements for the testing of backflow devices, which must be completed by a Sacramento County Environmental Management Department certified backflow prevention assembly tester.
For Testers: All backflow test reports should be submitted electronically at Folsom.tokaytest.com. To request a username and password for the site, please submit the Backflow Tester's information form. For assistance using the site, please watch the video tutorial linked below.
