Rust-Colored Water: Causes and Explanations

Rust coloring in water can occur when the flow of water through a pipe comes in contact with oxidized iron (rust) sedimentation caused by corrosion inside either water mains or the plumbing in your building. The result is a brown/orange/yellow coloring to the water. Despite this discoloration, the water is safe to drink and there is not a health concern.

What can be done about discoloration depends on the source. Below is some information about what can cause discoloration and what should be done to correct it.

Discoloration caused by municipal water mains.


Discoloration in the municipal water supply is typically caused by an event that impacts the water flow in the distribution system. The sedimentation in the mains is stirred up and mixed into the flow of water. Some examples of these types of events are: a water main break, fire hydrant usage (either hydrant flushing or during a fire), or construction work involving water mains.

Road construction during 2018 was a cause of water discoloration in Mayville. Closing water valves at various locations around the city altered the flow of the water through the system and stirred up the sedimentation in water mains throughout the city. Due to the length of time the water valves had to be closed during construction, it may take several months after the construction is complete for the system to settle back down and return to normal.

Signs discoloration may be caused by municipal water mains:

  • Discoloration is at every faucet in your building
  • It takes several minutes to clear the water when running it at high pressure
  • Discoloration still continues while water is being used


After one of the types of events listed above, the system needs to be cleared of sedimentation. Letting your cold water run for a few minutes near the location where the water enters your building (such as a laundry tub or first floor sink) should help clear it up. It is also recommended that you wait until the water is cleared before using the hot water, dishwasher, or washing machine to avoid allowing the sediment to collect in these appliances.

Routine maintenance of the water distribution system helps reduce the buildup of rust sedimentation in the water mains. This is accomplished by flushing water through the system using fire hydrants. The City of Mayville flushes fire hydrants in May and October of every year. Notices will be posted in advance of the dates the fire hydrants will be flushed – watch for these notices both on your water bill and in the Dodge County Pionier. Please note that if you run your water a short time after flushing has been completed near your building, you may notice some temporary water discoloration.

Discoloration caused by plumbing in your building.


Metal plumbing used inside a building is typically made of either copper or galvanized steel pipe. Galvanized steel piping was used in older buildings and will corrode over time, causing a rusty discoloration of water. An old water heater may also cause discoloration of water.

Signs discoloration may be due to plumbing in your building:

  • Discoloration typically occurs every morning or after several hours of inactivity, then clears later
  • The water clears within 2 minutes or less (the time it takes for all the water that had been sitting in the pipes within the building to clear out and be replaced with fresh water)
  • Discoloration is only at certain faucets in the building
  • Only the hot water is discolored and the cold water is clear


Water discoloration due to plumbing inside your building cannot be fixed through hydrant flushing. It is recommended that you contact a plumber to help locate any plumbing fixtures that may cause water discoloration, such as galvanized steel plumbing or an old water heater.

If you are unsure of the source of discoloration, a Mayville Utility employee can remove your water meter and inspect the water as it enters the building. This will help determine if the water entering the building is discolored or if the source is more likely the plumbing inside the building.

If you have any questions about your water, please feel free to call the Mayville Utility Department at 920-387-7906.
