City of Mattoon Fire Hydrant Flushing

City of Mattoon Fire Hydrant Flushing

October 9, 2026

The City of Mattoon, Public Works Department, will begin flushing fire
hydrants on Monday October 12th, 2026, and continue until all lines are
flushed. Flushing will be conducted on weekdays between 6:00 a.m. and
3:00 p.m.
Hydrant flushing is done to ensure all City hydrants and water lines are
operating properly and will be usable during a fire emergency.
Hydrant flushing may cause discoloration of your household water in or near
the areas being tested, which is a result of iron deposits being disturbed
during the flushing process.
Iron deposits can build up inside pressure tanks, water heaters and water
pipes. It occasionally breaks loose, causing rusty water to flow when faucets
are first opened. This happens especially when city or household water lines
are disturbed, (e.g., moved, replaced, back flushed, or repaired) and rust
breaks loose from old pipes
Residents are advised to check their water for signs of discoloration prior to
doing laundry. If you notice discoloration in the water, let it run until it clears
before doing laundry, usually this takes less than five minutes. If laundry
appears stained, keep the articles wet and rewash them using a rust
removing compound which is sold at local stores. Do not bleach stained
laundry as it will “set” the stain.
Please be advised that the water is completely safe to drink at all times While
this work is being done.
