Water & Sewer

Areas of Dayton have begun the transition from private water and sewer systems to city services. As more businesses and residents hook up to these utilities, we have been inspecting the work of the contractors to ensure old septic tanks have been properly abandoned. As part of the utility hook ups, MXU devices are being installed to make reading water meters less invasive for property owners, and to cut costs for staff. The water and sewer department monitors the City’s infrastructure and provides maintenance. Some maintenance most noticeable to the public is the routine flushing of fire hydrants which happens in April and October each year.

Hydrant Flushing

The semi-annual water main flushing program occurs every fall and spring. The process of flushing the water system may result in low water pressure, cloudy or discolored water during the days the system is being flushed. The discolored water is not dangerous to your health. Please be aware of the water quality while doing laundry or other tasks that require rust-free water.  Flushing fire hydrants and water mains provide several benefits to the water users of our systems including improving water quality and verifying operation for maintenance or repair.

Resident Tips When Hydrant Flushing:

  • Avoid using washing machine during times of hydrant flushing.
  • If discolored water occurs, simply run the cold water for a few minutes until it clears.  This will allow the sediment to work through your pipes.
  • In some cases, the discoloration may linger for a few hours.  This discoloration of the water only affects the appearance and does not affect the water quality.
  • If water pressure remains low after the flushing has been completed, check your faucet screens or any water filters for trapped particles.
  • If the problem persists, please contact Public Works.

For questions or concerns, please do not hesitate to contact Public Works at (763) 427-3224. 

Water Quality Reporting Forms

There are two forms, an initial questionnaire which needs to be filled out on the first contact which is designed to gather specific information about the home and types of treatment the home has. The water quality tracking form should be used for every subsequent reporting of water quality issues. If you have questions please contact Public Works on 763-427-3224.
