Nov 3 AFD Hydrant Inspections Begin in Zone 5

AFD operation runs to November 14. This operation may cause pressure drop, rusty water, check water before doing laundry.  

The Fire Department will inspect fire hydrants in Zone 5 (south east corner of Arlington, pictured below). Hydrants in this zone are opened, flushed, and inspected to verify proper drainage, ensuring they do not freeze in winter. The flushing is not as involved as the DPW operation and is unlikely to result in significant loss of water pressure or rusty water. However, if you see this activity in your neighborhood, and experience rusty water, it is advised that you run your cold faucets until you have clean water. Do not run your hot water or do laundry until your water is clear. If problems persist, please contact DPW Dispatch at 781-316-3301. 

Zone 5 is approximately the area south of Mass Ave to Route 2 from Grove Street to the Cambridge line.

DPW Annual Hydrant Flushing and Valve Testing Planned for Spring 2026

To better information the public of these operations, Arlington Public Works Water Division initiate an Arlington Alert when they will be in their area flushing hydrants. The calls will go out between 1:00-2:00 p.m. the day of a flushing operation. Flushing operations generally occur between 3:00 p.m. - 11:00 p.m. 
 
In order to receive these notifications, you must have your contact information in our Arlington Alert System. If you are already subscribed to Arlington Alerts, no further action is required by you. If you are not, or are not sure, you can subscribe from the Arlington Alerts page. 

Please note the Arlington Alert system can send targeted notifications and DPW is good at finishing the areas they plan to work on. However, some calls may reach beyond the targeted region and DPW may be forced to return to an area due to unforeseen delays. This may result in residents receiving multiple calls during the hydrant flushing season.
