Low-Flow Hydrant Flushing

Low-Velocity Water Main Flushing Program: TWW is conducting low-velocity flushing at fire hydrants in targeted areas throughout the service area. These efforts will continue into the summer months to optimize chlorine residuals which help mitigate pathogens' growth, including Legionella. These efforts include opening fire hydrants, sometimes for extended periods, and sampling until the area receives optimal chlorine residuals. By conducting these efforts, TWW will be able to identify areas requiring permanent flushing devices. Residents need to know that fire hydrants opened and equipped with specialized equipment to facilitate the low-velocity water main flushing may remain open for extended periods with signage. Please do not tamper with flowing hydrants.
