Backflow Prevention Program
Installation and annual testing of backflow prevention assemblies is a state requirement to help protect water quality and public health.
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). This applies to all commercial/industrial, large multifamily and some smaller multifamily and residential customers connected to the city's water supply. Properly working backflow prevention assemblies keep drinking water clean and safe.
