What is the cause of discolored water or water that looks dirty?
Water discoloration is likely a result of rust or iron oxides that comes from the pipes. Some of the Marietta water distribution system is cast iron and ductile iron pipes. When water stands still in public water mains or in a customer's galvanized service line or internal plumbing, it may naturally dissolve the iron. If you have rusty water when you first use it in the morning, the cause is probably from your inside plumbing or service line. If your water suddenly becomes rusty, it may be caused by fire hydrant flushing, construction in the area or fire hydrant use in the area. This is usually temporary and may clear on its own or by having water department personnel flush the line. Water discolored from rust has no health significance. Although it is safe to drink, it is understandable that people will find it aesthetically unappealing.

Our flushing program takes care of this problem in a few minutes, but can also create some problems for you, our customer. If you are running water when we are flushing, you could get some dirty water. If this does happen, you should not run your hot water or do any laundry. Turn on and run your cold water until the dirty water clears out of your pipes, then flush your hot water tank, if necessary, by opening the valve at the bottom of the tank. If you are doing laundry, do not dry these clothes. Washing these items again will normally take care of this problem, but if not, you can contact Marietta Water at 770-794-5230 for help.

We would like to apologize for any inconvenience this may cause. Flushing is done to prevent problems and ensure that you have fresh drinking water at all times.
