Fire Hydrant Flushing


The City of Mattoon Public Works Department, will begin flushing fire hydrants Monday, May 13, 2024 and continue until all lines are flushed.


Flushing will be conducted 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.


Please be advised that the water is completely safe to drink at all times while this work is being done.
