State regulations require the City of Boulder to maintain a Backflow Prevention Program to track the installation and annual testing of backflow prevention assemblies on all hazardous cross-connections (potential points for contamination and backflow).
In 2023, the City of Boulder received three violations from the Colorado Department of Public Health and Environment for not fully meeting state regulatory requirements. As of December 2023, these violations are now resolved, and the city is in full compliance with the state’s backflow regulations.
