NEW BRUNSWICK, NJ (October 13, 2025) - Fall hydrant flushing in New Brunswick begins on Oct. 14. Most City fire hydrants will be flushed between 10 p.m. and 2 a.m., at a time when demand is reduced.
Hydrant flushing programs are conducted in New Brunswick twice a year to remove iron deposits that build in water mains. Discoloration of the water may occur due to flushing, but the water remains safe for use. The discoloration during the flushing process occurs because iron deposits are dislodged from pipes by water pressure, a necessary maintenance step to maintain water quality and flow.
Residents should avoid using hot water or doing laundry until the water discoloration disappears, as iron deposits can build up in water heaters and possibly stain laundry.
To find out where and when the hydrant flushing is scheduled, please check the City's website, Facebook page, or X (formerly known as Twitter) feed each day.
