Public Water Systems should be aware that the addition of antifreeze to fire hydrants does not comply with Section 19-13-B80 of the Regulations of Connecticut State Agencies. In the past Public Water Systems or local fire department personnel may have added chemicals to fire hydrants in an effort to prohibit freezing of water in the hydrants during the winter season. While freezing of fire hydrants is a concern, adding chemicals creates a risk of water quality contamination and also has security implications, involving a port of entry into the distribution system. Public Water Systems should minimize freezing of water in fire hydrants, by such methods as repairing or replacing hydrants, and should involve the local fire department in this matter. More information on this topic, such as the New England Water Works Association's video "Being Prepared: Procedures for Fire Hydrant Maintenance" and the American Water Works Association (AWWA) Manual "Installation, Field Testing, and Maintenance of Fire Hydrants (M17)", can be obtained from the AWWA web site.
