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.

Odd/Even Watering Restrictions May 1st - October 31st

To reduce peak water usage in areas served the municipal water system, the City of Dayton has implemented an odd-even irrigation ban, pursuant to City Code Chapter 52.057. Irrigation will be restricted from May 1st through October 31st, 2021. Prohibited hours for irrigation are between the hours of 10:00 a.m. through 7:00 p.m. Homeowners and businesses with addresses ending in an odd number, may water on odd numbered calendar days. Those with addresses ending in an even number, may water on even numbered days. The restrictions apply to all City water customers. Residents who use private wells for irrigation are exempt from these restrictions.

New seed and sod are exempt from the odd-even requirement. Sod may be watered every day for four weeks from installation while the irrigation restriction is in place, however, irrigation shall comply with the prohibited hours during this four-week period.

The penalty for violating restrictions is $100 for each day of violation. You will receive one written warning before you are penalized. Property owners will be notified in person (if present) and will receive a violation by mail. Any fine(s) will be added to the utility bill.

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.

Water Conservation

  • Summer generates an increase in water usage; this is due primarily to irrigation of lawns. The majority of new homes have an automatic sprinkler system and these systems are set up initially by the builder to run frequently to establish newly installed sod. Once the turf is established the irrigation system should be adjusted to water less frequently. To maintain a lawn takes approximately 1” of water per week during the summer, which equates to resetting the irrigation system to run 3 times a week for 20 minutes.
  • The City of Dayton has a tiered water billing system, the more water you use the more you are billed. Water used at the home is monitored by a meter that is installed where the water enters the home. Water entering the home is billable no matter what it is used for, so the water used for lawn maintenance is billed in the same way the water used for the laundry or showering is billed. A home with an automatic sprinkler system and an average winter bill of $86 may increase to $228 a billing cycle during peak use due to an unadjusted sprinkler system.
  • Reducing residential watering can save you money and help the City manage future infrastructure costs so improvements do not have to be made prematurely. In addition to preserving water outside, there are ways to conserve water within the household. Some of these things are simple such as turning off the faucet while brushing teeth, taking showers instead of baths, and using only full loads of laundry to be washed so that no water is wasted. Household water leaks may also occur, so make sure those repairs are completed as soon as possible.
