Water Discoloration Notice

The City of Mayville anticipates some temporary water discoloration as a well currently under construction is returned to service. This is a normal part of the process and is related to iron being stirred up as water flow and pathways change within the system.

These improvements will help ensure water quality and regulatory compliance for years to come by replacing aging equipment and processes. We apologize for any inconvenience.

If you experience discolored water, please allow the water to run for 5–10 minutes, or until it runs clear.

If you have any questions or concerns, please contact the Mayville Water & Wastewater Utility at 920-387-7906.

Thank you for your patience and understanding!

HYDRANT FLUSHING NOTICE
April 21 – June 5, 2026

The Mayville Water Utility will be flushing fire hydrants and mains for the semi-annual pressure, flow and maintenance check. Hydrants will be flushed April 21th through

June 5th from 6:00 a.m. to 4:00 p.m. dependent upon weather.

Flushing of the water mains is conducted by opening the fire hydrants. The purpose of flushing is to remove sediment and mineral deposits that settle on the bottom of the water mains. The City of Mayville flushes 31 miles of water main, which allows us to not only remove any sediment that has accumulated in the mains, but to also verify the proper operation of hydrants and valves and maintain firefighting capabilities.

Although this flushing is essential to provide water quality and prevent long-term sedimentation and discoloration issues, it can cause short-term discoloration as the sediment is disturbed due to the higher water flows.
When sediment gets stirred up in the water system, the resulting discoloration will typically last approximately 2-4 hours or less. After this time, the sediment will settle back out, and the water will become clear. You can speed up the process by turning on the cold water tap at full pressure nearest where the water enters your home, such as a basement laundry tub, or a first-floor sink, and allowing the water to run until it is clear.

If you have any questions concerning fire hydrant flushing, please call 387-7906 or e-mail [email protected].
