The Town of Salem’s annual hydrant flushing program will begin the week of April 6, 2026, and will continue every Tuesday for several weeks from 11:00 p.m. to 5:00 a.m.
This important overnight maintenance work helps ensure Salem’s fire hydrants are ready to operate properly in the event of an emergency. During the program, Utilities Department crews will follow predetermined routes throughout town to inspect, service, and flush hydrants under full flow.
As part of the process, crews visually inspect each hydrant for damage, lubricate operating mechanisms, replace gaskets when needed, and confirm that each hydrant drains properly after use to help prevent freezing during colder weather. Crews also trim back vegetation near hydrants to keep them visible and accessible, and all maintenance information is logged for recordkeeping.
Any hydrants found to need repairs are addressed separately during normal shifts. On average, each crew services between 25 and 35 hydrants per shift, and the overall flushing program typically takes about 4 to 6 weeks to complete.
This work plays an important role in maintaining Salem’s water system and fire protection infrastructure. Each year, the Town invests significant time and resources into hydrant maintenance to help ensure reliable water delivery during emergencies and to support Salem’s favorable fire insurance classification.
Residents may notice temporary water discoloration or lower water pressure in some areas during flushing operations. This is normal and typically resolves quickly. Running cold water for a short time can help clear any discoloration.
Property owners are also reminded to keep the area around hydrants free of fences, shrubs, flowers, or other obstructions. Hydrants are serviced at least twice each year, and clear access is essential for both routine maintenance and emergency response.
Anyone who sees a hydrant that appears damaged, has a missing or bent flag, or is being used without authorization is asked to contact the Water Department.
