Towns flush fire hydrants as preventative maintenance. The increased pressure cleans out built-up sediment like iron, tests water line pressure and integrity, flushes stagnant water that can accumulate in "dead legs," and ensures firefighters have reliable access to water during an emergency. When they do this they increase chlorine (sodium hypochlorite) levels to ensure increased sediment levels are properly disinfected to maintain regulatory compliance with NYSDOH. You may experience slight temporary drops in water pressure or rust-colored tap water. The discolored water is usually due to an increase in iron levels which may cause taste and odor problems (usually bleach smell and oily or earthy odors from the iron). You should avoid drinking it until it runs clear and wait to do laundry so your clothes don't stain from the iron. If you notice discolored water, run your cold water taps for 15 to 20 minutes and flush toilets until it clears. Avoid entraining this water into your hot water system as it may take longer to flush it from there. Avoid using refrigerator drinking water filters or other potable water systems like RO filters until the water runs clear as it may bind or clog these filters. You may also need to remove and clean your tap sediment screens of the debris.
