City of Sheridan

A Backflow Device (assembly) is used to protect potable water (drinking water) supplies from contamination or pollution due to backflow. Essentially, they help protect our City’s drinking water from pollutants “back-flowing” into our water system. These devices are required to be installed, tested upon installation, and tested annually thereafter. 

In order to remain in compliance with Wyoming DEQ, and City Ordinance No. 1946, your assemblies need to be tested annually. We track the testing of all of the City’s devices to ensure regular testing and maintenance is being completed. Your devices are on an assigned schedule-code, which means your specific devices will be due for testing the same month of each year, which is good to keep in mind for planning ahead. 

Give your backflow tester a call to schedule testing and ensure they can complete testing prior to your due date. If you’re not sure who previously tested the backflow assemblies at your location, don’t hesitate to give us a call at the City and we can let you know who has provided test results in the past. (You may also find this information on a tag located directly on your backflow device at times). That said, you are not required to utilize the same company every year, as long as the devices get tested appropriately and on time, so feel free to call any of the approved providers to schedule.

There are many companies that provide testing for backflow devices. The local testers approved in our system include the following:
